935,000,000,000 YBN | 4) There is a pattern in the universe. Light particles move from highly dense volumes of space to volumes of less density. In low density volumes, light particles slowly accumulate to form atoms of Hydrogen and Helium which exist as gas clouds (like the Magellanic Clouds or Orion nebula). These gas clouds, called nebulae continue to accumulate trapped light particles. At points of high density planets and stars form and the cloud is eventually dense enough to become a galaxy of stars. The stars emit light particles back out to the rest of the universe, where the light again becomes trapped and forms new clouds. Around each star are many planets and pieces of matter. On many of the planets rotating around stars, living objects evolve that can copy themselves by converting matter around them into more of them. Living objects need matter to replace matter lost from the constant emitting of light particles (decay). Like bacteria, these living objects grow in number, with the most successful organisms occupying and moving around many stars. These advanced organisms then move the groups of stars they control, as a globular cluster, away from the plane of the spiral galaxy. As time continues, all of the stars of a galaxy are occupied by living objects who have organized their stars into globular clusters, and these globular clusters together, form a globular galaxy. The globular galaxy may then exist for a long time living off the matter in stars, in addition to matter from external sources. So free light particles are trapped into volumes of space that grow in density first forming atoms, then gas clouds, then stars, a spiral galaxy, and finally a globular galaxy. Stars at our scale may be light particles at a much larger scale, just as light particles at our scale may be stars at a much smaller scale. This system may go on infinitely in both larger and smaller scale. |

Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard's Loop - a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion. But the obscuring dust of LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away. At that distance, this 1 degree wide field of view would span less than 10 light-years. PD source: http://apod.nasa.gov/apod/image/ 0705/ldn1622_carboni.jpg | |

Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers. Still, this beautiful digital image shows off the Iris Nebula's range of colors and symmetries in impressive detail. Within the Iris, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the dusty clouds glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs. As shown here, the bright blue portion of the Iris Nebula is about six light-years across.

M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the constellation Sagittarius. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars, which lie outside the picture to the upper left. The glow of these patterns accentuates the three-dimensional structure of the gases. The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The warmed surfaces glow orange and red in this photograph. The intense heat and pressure cause some material to stream away from those surfaces, creating the glowing veil of even hotter greenish gas that masks background structures. The pressure on the tips of the waves may trigger new star formation within them. The image, roughly 3 light-years across, was taken May 29-30, 1999, with the Wide Field Planetary Camera 2. The colors in the image represent various gases. Red represents sulfur; green, hydrogen; and blue, oxygen.

Currently, space weather forecasters are observing a moderate geomagnetic storm (G-2 on the NOAA Space Weather Scales) and a minor (S-1) solar radiation storm. Earlier Wednesday an X-class flare produced a strong (R-3) radio blackout. (Click image for larger view of the sun taken on Jan. 19, 2005, at 2:19 p.m. EST.

[1] RNA is a versatile molecule. In its most familiar role, RNA acts as an intermediary, carrying genetic information from the DNA to the machinery of protein synthesis. RNA also plays more active roles, performing many of the catalytic and recognition functions normally reserved for proteins. In fact, most of the RNA in cells is found in ribosomes--our protein-synthesizing machines--and the transfer RNA molecules used to add each new amino acid to growing proteins. In addition, countless small RNA molecules are involved in regulating, processing and disposing of the constant traffic of messenger RNA. The enzyme RNA polymerase carries the weighty responsibility of creating all of these different RNA molecules. The RNA Factory RNA polymerase is a huge factory with many moving parts. The one shown here, from PDB entry 1i6h, is from yeast cells. It is composed of a dozen different proteins. Together, they form a machine that surrounds DNA strands, unwinds them, and builds an RNA strand based on the information held inside the DNA. Once the enzyme gets started, RNA polymerase marches confidently along the DNA copying RNA strands thousands of nucleotides long. Accuracy As you might expect, RNA polymerase needs to be accurate in its copying of genetic information. To improve its accuracy, it performs a simple proofreading step as it builds an RNA strand. The active site is designed to be able to remove nucleotides as well as add them to the growing strand. The enzyme tends to hover around mismatched nucleotides longer than properly added ones, giving the enzyme time to remove them. This process is somewhat wasteful, since proper nucleotides are also occasionally removed, but this is a small price to pay for creating better RNA transcripts. Overall, RNA polymerase makes an error about once in 10,000 nucleotides added, or about once per RNA strand created. Poisoning Polymerase Since RNA polymerase is absolutely essential for the life of the cell, it is a sensitive target for poisons and toxins. The most powerful of these poisons is alpha-amanitin, a small circular peptide created by the death cap mushroom. Eating even one of these mushrooms will lead to coma and death in a manner of days, as the poison attacks RNA polymerase throughout the body. Surprisingly, it binds on the back side of RNA polymerase, away from the active site and away from the binding site for the DNA and RNA. It does not physically block the active site, like most inhibitors, but instead jams the mechanism of the enzyme. RNA polymerase is a highly mobile enzyme, that flexes and changes shape as it performs the sequential steps of binding to DNA, unwinding it, and then building the RNA strand. As seen in PDB entry 1k83, the poison binds between two subunits of the protein, gluing them together and blocking these essential motions.

This tree emphasizes vertical (as opposed to horizontal) evolution and the close relationship between eukaryotes and the Archaebacteria. The deep branching (>3.5 Giga (109) years ago, Gya) of CYANOBACTERIA (Cy) and other Eubacteria (purple), the shallow branching (approx1 Gya) of plants (Pl), animals (An) and fungi (Fu), and the early origin of mitochondria (Mi), were based on interpretations of the geochemical and fossil record7, 8. Some deeply branching amitochondriate (Am) species were believed to have arisen before the origin of mitochondria44. Major symbiotic events (black dots) were introduced to explain the origin of eukaryotic organelles42, but were not assumed to be associated with large transfers of genes to the host nucleus. They were: Eu, joining of an archaebacterium host with a eubacterium (presumably a SPIROCHAETE) to produce an amitochondriate eukaryote; Mi, joining of a eukaryote host with an alpha-proteobacterium (Ap) symbiont, leading to the origin of mitochondria, and plastids (Ps), joining of a eukaryote host with a cyanobacterium symbiont, forming the origin of plastids on the plant lineage and possibly on other lineages. b) The present view, based on extensive genomic analysis. Eukaryotes are no longer considered to be close relatives of Archaebacteria, but are genomic hybrids of Archaebacteria and Eubacteria, owing to the transfer of large numbers of genes from the symbiont genome to the nucleus of the host (indicated by coloured arrows). Other new features, largely derived from molecular-clock studies16, 39 (Box 1), include a relatively recent origin of Cyanobacteria (approx2.6 Gya) and mitochondria (approx1.8 Gya), an early origin (approx1.5 Gya) of plants, animals and fungi, and a close relationship between animals and fungi. Coloured dashed lines indicate controversial aspects of the present view: the existence of a premitochondrial symbiotic event and of living amitochondriate eukaryotes, ancestors of which never had mitochondria. c) The times of divergence of selected model organisms from humans, based on molecular clocks. For the prokaryotes (red), because of different possible origins through symbiotic events, divergence times depend on the gene of interest. source: http://www.nature.com/nrg/journa l/v3/n11/full/nrg929_fs.html | |

[1] Evolutionary relationships of model organisms and bacteria that show unusual reproductive strategies. This phylogenetic tree (a) illustrates the diversity of organisms that use the alternative reproductive strategies shown in (b). Bold type indicates complete or ongoing genome projects. Intracellular offspring are produced by several low-GC Gram-positive bacteria such as Metabacterium polyspora, Epulopiscium spp. and the segmented filamentous bacteria (SFB). Budding and multiple fission are found in the proteobacterial genera Hyphomonas and Bdellovibrio, respectively. In the case of the Cyanobacteria, Stanieria produces baeocytes and Chamaesiphon produces offspring by budding. Actinoplanes produce dispersible offspring by multiple fission of filaments within the sporangium. source: http://www.nature.com/nrmicro/jo urnal/v3/n3/full/nrmicro1096_fs.html (Nature Reviews Microbiology 3 [2] Electron micrograph of a Pirellula bacterium from giant tiger prawn tissue (Penaeus monodon).

[1] Listeria monocytogenes is a Gram-positive bacterium, in the division Firmicutes, named for Joseph Lister. It is motile by means of flagella. Some studies suggest that 1 to 10% of humans may carry L. monocytogenes in their intestines. Researchers have found L. monocytogenes in at least 37 mammalian species, both domesticated and feral, as well as in at least 17 species of birds and possibly in some species of fish and shellfish. Laboratories can isolate L. monocytogenes from soil, silage, and other environmental sources. L. monocytogenes is quite hardy and resists the deleterious effects of freezing, drying, and heat remarkably well for a bacterium that does not form spores. Most L. monocytogenes are pathogenic to some degree. source: http://en.wikipedia.org/wiki/Ima ge:Listeria.jpg [2] These are bacteria (about 0.3 µm in diameter) that do not have outer walls, only cytoplasmic membranes.

2,730,000,000 YBN | 80) Endo and exocytosis evolve. Cells can now eat other cells. In endocytosis the plasma membrane folds inward to bring substances into the cell. In Exocytosis substances contained in vesicles are released from the cell. |
[1] Endocytosis and Exocytosis: For example, this electron micrograph is showing the process of exocytosis . The process begins by fusion of the membranes at the peripheral pole of the granule. Then an opening is created which widens to look like an omicron figure. This opening allows the granular material to be released. The membrane is now part of the plasma membrane and any proteins carried with it can be incorporated into the plasma membrane. Note that there is no coating on the membrane. This figure was taken from Alberts et al, Molecular Biology of the Cell, Garland Publishing Third Edition, 1994 In contrast, this micrograph shows a figure which looks something like an omicron, however, this view is showing receptor mediated endocytosis of virus particles. In both cases, the membrane is coated with clathrin and these represent classical receptor mediated endocytosis profiles. Most ligands cannot be visualized by themselves, like a virus particle. Therefore, the cytochemist must attach label to the ligand. Alternatively, the cytochemist could immunocytochemically detect the receptor with antibodies that recognize the extracellular domain. This figure was taken from Endocytosis, Edited by Ira Pastan and Mark C. Willingham, Plenum Press, N.Y., 1985 COPYRIGHTED source: http://www.cytochemistry.net/cel l-biology/end7.jpg [2] Pinocytosis In the process of pinocytosis the plasma membrane froms an invagination. What ever substance is found within the area of invagination is brought into the cell. In general this material will be dissolved in water and thus this process is also refered to as ''cellular drinking'' to indicate that liquids and material dissolved in liquids are ingested by the cell. This is opposed to the ingestion of large particulate material like bacteria or other cells or cell debris. UNKNOWN source: http://academic.brooklyn.cuny.ed u/biology/bio4fv/page/endocytb.htm | |
2,700,000,000 YBN | 60) Eukaryotic cell. The first cell with a nucleus. The first protist. The nucleus may develop from the infolding of plasma membrane. In prokaryotic cells the DNA is not membrane enclosed while in eukaryotic cells most of the DNA is contained in a nucleus. Eukaryotic cells are generally much larger than prokaryotic cells. Unlike prokaryotic cells, eukaryotic cells have a cytoskeleton. Eukaryotic cells may have mitochondria and plastids, which prokaryotic cells lack. DNA in prokaryotic cells is usually a single circular chromosome, while DNA in the nucleus of eukaryotes contains linear chromosomes. Like prokaryotes, this cell is probably haploid (a single unique DNA), most eukaryotes are diploid (having two sets of DNA). All protists, fungi, animals and plant cells descend from this common eukaryotic cell. |

2,690,000,000 YBN | 208) The eukaryote flagellum and cilia evolve. |
[1] Cilia and flagella are projections from the cell. They are made up of microtubules , as shown in this cartoon and are covered by an extension of the plasma membrane. They are motile and designed either to move the cell itself or to move substances over or around the cell. The primary purpose of cilia in mammalian cells is to move fluid, mucous, or cells over their surface. Cilia and flagella have the same internal structure. The major difference is in their length. This figure shows a cross section of a cilium next to a longitudinal section. Below, we will see how the microtubules are organized in the core (shown in the cartoon in this figure). Also shown is the centriole or basal body that organizes the formation and direction of the cilia. COPYRIGHTED source: Description Transmission electron microscope image, showing an example of green algae (Chlorophyta). Chlamydomanas reinhardtii is a unicellular flagellate used as a model system in molecular genetics work and flagellar motility studies. This image is a longitudinal section through the flagella area. In the cell apex is the basal body that is the anchoring site for a flagella. Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets(see structure at bottom center of image). The two inner microtubules of each triplet in a basal body become the two outer doublets in the flagella. This image also shows the transition region, with its fibers of the stellate structure. The top of the image shows the flagella passing through the cell wall. Date 20 September 2007 Source Source and public domain notice at http://remf.dartmouth.edu/imagesindex.ht ml Author Dartmouth Electron Microscope Facility, Dartmouth College PD [2] This figure shows an electron micrograph of a cross section of a cilium. Note that you can see the dynein arms and the nexin links. The dynein arms have ATPase activity. In the presence of ATP, they can move from one tubulin to another. They enable the tubules to slide along one another so the cilium can bend. The dynein bridges are regulated so that sliding leads to synchronized bending. Because of the nexin and radial spokes, the doublets are held in place so sliding is limited lengthwise. If nexin and the radial spokes are subjected to enzyme digestion, and exposed to ATP, the doublets will continue to slide and telescope up to 9X their length.

(a) Each chromosome is made up of a tightly coiled strand of DNA. (b) DNA’s uncoiled state reveals its familiar double helix shape. If DNA is pictured as a twisted ladder, its sides, made of sugar and phosphate molecules, are connected by (c) rungs made of chemicals called bases. DNA has four bases—adenine, thymine, guanine, and cytosine—that form interlocking pairs. The order of the bases along the length of the ladder is the DNA sequence.

[1] snowball Earth UNKNOWN source: http://www.cosmosmagazine.com/fi les/imagecache/feature/files/features/pr int/20090528_snowball_earth.jpg [2] Snowball Earth Snowball Earth describes a theory that for millions of years the Earth was entirely smothered in ice, stretching from the poles to the tropics. This freezing happened over 650 million years ago in the Pre-Cambrian, though it's now thought that there may have been more than one of these global glaciations. They varied in duration and extent but during a full-on snowball event, life could only cling on in ice-free refuges, or where sunlight managed to penetrate through the ice to allow photosynthesis.

2,300,000,000 YBN | 48) The oldest "Red Beds", iron oxide formed on land, begin here, and are also evidence of more free oxygen in the air of Earth. |
[1] http://www.kgs.ukans.edu/Extension/redhi lls/redhills.html source: http://www.kgs.ukans.edu/Extensi on/redhills/redhills.html [2] In Archean rocks, metals tend to occur in low oxidation states (for example, Fe2+ instead of Fe3+) indicating a high metal:oxygen ratio in the oceans and atmosphere. The sediments are essentially rust-free. After the late Proterozoic, sedimentary deposits often have reddish colors and are called red beds due to the presence of iron-oxide coatings between sand grains. From the later Proterozoic onward, enough free oxygen has been available to oxidize iron in sediments. A sandstone butte outside of Sedona, Arizona. Public domain image by Jon Sullivan.

Unbroken lines indicate phylogenetic relationships that are firmly supported by available data; broken lines indicate uncertainties in phylogenetic placement, resolution of which will require additional data. Color coding of organismal genus names indicates mitochondrial genomes that have been completely (Table 1), almost completely (Jakoba, Naegleria and Thraustochytrium) or partially (*) sequenced by the OGMP (red), the FMGP (black) or other groups (green). Names in blue indicate those species whose mtDNAs are currently being sequenced by the OGMP or are future candidates for complete sequencing. Amitochondriate retortamonads are positioned at the base of the tree, with broken arrows denoting the endosymbiotic origin(s) of mitochondria from a Rickettsia-like eubacterium.

1,570,000,000 YBN | 197) The ancestor of all living eukaryotes divides into bikont and unikont descendants. Bikonts lead to all Chromalveolates, Excavates, Rhizaria, and Plants. Unikonts lead to all Amoebozoa, Animals and Fungi. |
[1] Figure 1: Figure 1. Eukaryote phylogeny integrating ultrastructure, sequence trees, gene fusions and molecular cladistic markers. The unikont topology is established, but the branching order of the six bikont groups remains uncertain. The single enslavement [12] of a red alga (R) to create chromalveolates is supported by a plastid glyceraldehyde phosphate dehydrogenase (GAPDH) replacement [13]. Whether there was a single enslavement of a green alga (G) to form cabozoa or two separate enslavements (asterisks) to form Cercozoa and Excavata is uncertain [12], as is the position of Heliozoa [14]. Polyubiquitin [15] and EF-1α[16] insertions strongly support the clades core Rhizaria and opisthokonts. The inset shows the BamHI restriction fragment from H. cantabrigiensis that was sequenced and analysed in this study, spanning the DHFR and the amino terminus of the TS gene (red, introns are green). The length of the noncoding regions upstream and downstream of the DHFR gene from one of the clones is indicated.

[1] Volvoxcell differentiation. The pathways leading to germ cells or somatic cells are controlled by genes that cause cells to follow one or the other fate. Mutations can prevent the formation of one of these lineages. http://www.devbio.com/chap02/link0204.sh tml Although all the volvocaceans, like their unicellular relative Chlamydomonas, reproduce predominantly by asexual means, they are also capable of sexual reproduction, which involves the production and fusion of haploid gametes. In many species of Chlamydomonas, including the one illustrated in Figure 2.10, sexual reproduction is isogamous (“the same gametes”), since the haploid gametes that meet are similar in size, structure, and motility. However, in other species of Chlamydomonas—as well as many species of colonial volvocaceans—swimming gametes of very different sizes are produced by the different mating types. This pattern is called heterogamy (“different gametes”). But the larger volvocaceans have evolved a specialized form of heterogamy, called oogamy, which involves the production of large, relatively immotile eggs by one mating type and small, motile sperm by the other (see Sidelights and Speculations) UNKNOWN source: http://www.ncbi.nlm.nih.gov/book s/NBK10031/bin/ch2f12.jpg [2] Description English: Four Different Species of Volvocales Algae.

[1] Fig. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b). The position of the eukaryotic root has been nearly as controversial, but is less hard to establish: it probably lies between unikonts and bikonts (Lang et al., 2002; Stechmann and Cavalier-Smith, 2002, 2003). For clarity the basal eukaryotic kingdom Protozoa is not labelled; it comprises four major groups (alveolates, cabozoa, Amoebozoa and Choanozoa) plus the small bikont phylum Apusozoa of unclear precise position; whether Heliozoa are protozoa as shown or chromists is uncertain (Cavalier-Smith, 2003b). Symbiogenetic cell enslavement occurred four or five times: in the origin of mitochondria and chloroplasts from different negibacteria, of chromalveolates by the enslaving of a red alga (Cavalier-Smith, 1999, 2003; Harper and Keeling, 2003) and in the origin of the green plastids of euglenoid (excavate) and chlorarachnean (cercozoan) algae—a green algal cell was enslaved either by the ancestral cabozoan (arrow) or (less likely) twice independently within excavates and Cercozoa (asterisks) (Cavalier-Smith, 2003a). The upper thumbnail sketch shows membrane topology in the chimaeric cryptophytes (class Cryptophyceae of the phylum Cryptista); in the ancestral chromist the former food vacuole membrane fused with the rough endoplasmic reticulum placing the enslaved cell within its lumen (red) to yield the complex membrane topology shown. The large host nucleus and the tiny nucleomorph are shown in blue, chloroplast green and mitochondrion purple. In chlorarachneans (class Chlorarachnea of phylum Cercozoa) the former food vacuole membrane remained topologically distinct from the ER to become an epiplastid membrane and so did not acquire ribosomes on its surface, but their membrane topology is otherwise similar to the cryptophytes. The other sketches portray the four major kinds of cell in the living world and their membrane topology. The upper ones show the contrasting ancestral microtubular cytoskeleton (ciliary roots, in red) of unikonts (a cone of single microtubules attaching the single centriole to the nucleus, blue) and bikonts (two bands of microtubules attached to the posterior centriole and an anterior fan of microtubules attached to the anterior centriole). The lower ones show the single plasma membrane of unibacteria (posibacteria plus archaebacteria), which were ancestral to eukaryotes and the double envelope of negibacteria, which were ancestral to mitochondria and chloroplasts (which retained the outer membrane, red).

The neon water is brimming with dinoflagellates, single-celled plankton with tails that slosh around together in vast numbers. These creatures have been highlighting Earth’s coastlines for 1.2 billion years, and for the past few millennia, they’ve puzzled humans, who used to attribute the glow of some ocean water to magic or the gods.Dinoflagellates still puzzle us; we know how they glow, but not why. They might have evolved bioluminescence as a way of frightening predators, or to reveal those predators’ locations by flashing when touched. Alternatively, their bioluminescence may just be a fancy way of ridding themselves of oxygen radicals (because the chemical reaction requires oxygen). Whatever the answer, they certainly make for a nice holiday in the Bahamas. UNKNOWN source: http://www.lifeslittlemysteries. com/images/i/1651/original/dinoflagellat e.jpg | |

The cells are cylindrical with a rounded anterior and tapered posterior. The chloroplasts are well-developed, bright green, and sometimes have pyrenoids. They are often discoidal in shape but can also be ovate, lobate, elongate, U-shaped, or ribbon-shaped. Some researchers use the structure and position of the chloroplasts to divide the group into three subgenera. Even though they are able to photosynthesize, Euglena cells also have a phagotrophic ingestion apparatus. Euglena has one long, protruding flagellum and a shorter flagellum that is not usually visible. The euglenoids can glide and swim using their flagella, or can ooze along a substrate with an undulating, shape-changing, contraction motion called metaboly. The cytoplasm of Euglena and other euglenoids contains many paramylon starch storage granules. The euglenoid cells are covered by a pellicle composed of ribbonlike, woven strips of proteinaceous material that cover the cell in a helical arrangement from apex to posterior. Freshwater euglenoids have a contractile vacuole. Euglenoids sense light using a red pigmented eyespot or stigma and the paraflagellar body located at the base of the emergent flagella.

Note the parasite forms branching hyphae-like structures. Ichthyophonus hoferi has caused massive mortalities in herring in the Atlantic ocean, and has recently been reported to cause disease in wild Pacific herring from Washington through Alaska. COPYRIGHTED EDU source: http://oregonstate.edu/dept/salm on/projects/images/16Ichthyophonus.jpg [2] Microscopic appearence of the organism is dependent on its stage of development. The stages include (1) spore at ''resting'' stage, (2) germinating spore, (3) hyphal stage. It is believed that there are two forms of Ichthyophonus, both belonging to one genus. One of them is known as the ''salmon'' form, occuring in freshwater and cold-preferring sea fishes: this form is characterized by its ability to produce long tubulose germ hyphae. The other is called the ''aquarium fish'' form, typical of the tropical freshwater fishes. This form is completely devoid of hyphae. Developmental cycle of Ichthyophonus hoferi: 1-5 - development of ''daughter'' spores, 7-11 - development of resting spore from the ''daughter'' spore, 12-19 - development of resting spore by fragmentation.

[1] A general view of the life in the time frame from about 605 to 542 million years ago (the Vendian), is found at this New Zealand site which concentrates on the Ediacaran epoch; it mentions Australian and other geographic localities where the assemblages have been found. The fossil life is represented entirely by creatures with soft parts only. It is suggested that these may be ancestral to later phylla observed at the beginning of the Paleozoic.

Individual zooids can crawl about freely within the colony, but are connected to one another by thin “cables,” quickly retracting if disturbed. What makes the Pterobranchs even stranger than corals is that these slimy, slithering weirdos are “hemichordates,” closer to us vertebrates than to invertebrates like worms and jellyfish.

The ancestor of all chordates evolves "upside-down". Unlike earlier invertebrates, this ancestor and all vertebrates have their nerve cord near their back and their heart near their front. |

[1] FIG. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b). The position of the eukaryotic root has been nearly as controversial, but is less hard to establish: it probably lies between unikonts and bikonts (Lang et al., 2002; Stechmann and Cavalier-Smith, 2002, 2003). For clarity the basal eukaryotic kingdom Protozoa is not labelled; it comprises four major groups (alveolates, cabozoa, Amoebozoa and Choanozoa) plus the small bikont phylum Apusozoa of unclear precise position; whether Heliozoa are protozoa as shown or chromists is uncertain (Cavalier-Smith, 2003b). Symbiogenetic cell enslavement occurred four or five times: in the origin of mitochondria and chloroplasts from different negibacteria, of chromalveolates by the enslaving of a red alga (Cavalier-Smith, 1999, 2003; Harper and Keeling, 2003) and in the origin of the green plastids of euglenoid (excavate) and chlorarachnean (cercozoan) algae-a green algal cell was enslaved either by the ancestral cabozoan (arrow) or (less likely) twice independently within excavates and Cercozoa (asterisks) (Cavalier-Smith, 2003a). The upper thumbnail sketch shows membrane topology in the chimaeric cryptophytes (class Cryptophyceae of the phylum Cryptista); in the ancestral chromist the former food vacuole membrane fused with the rough endoplasmic reticulum placing the enslaved cell within its lumen (red) to yield the complex membrane topology shown. The large host nucleus and the tiny nucleomorph are shown in blue, chloroplast green and mitochondrion purple. In chlorarachneans (class Chlorarachnea of phylum Cercozoa) the former food vacuole membrane remained topologically distinct from the ER to become an epiplastid membrane and so did not acquire ribosomes on its surface, but their membrane topology is otherwise similar to the cryptophytes. The other sketches portray the four major kinds of cell in the living world and their membrane topology. The upper ones show the contrasting ancestral microtubular cytoskeleton (ciliary roots, in red) of unikonts (a cone of single microtubules attaching the single centriole to the nucleus, blue) and bikonts (two bands of microtubules attached to the posterior centriole and an anterior fan of microtubules attached to the anterior centriole). The lower ones show the single plasma membrane of unibacteria (posibacteria plus archaebacteria), which were ancestral to eukaryotes and the double envelope of negibacteria, which were ancestral to mitochondria and chloroplasts (which retained the outer membrane, red). source: http://aob.oxfordjournals.org/cg i/content/full/95/1/147/FIG2 [2] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

Arthropods include the trilobites, the crustaceans (shrimps, crabs, and lobsters), the Myriapoda (centipedes and millipedes), the Chelicerata (arachnids and horseshoe crabs) and the insects. All arthropods have a segmented body covered by an exoskeleton containing chitin, which serves as both armor and as a surface for muscle attachment. |

Representatives of three extinct groups. The head armor is especially well developed in Hemicyclaspis, an ostracoderm of the ''Cephalapsis'' type, in which the head is flattened and expanded into a large filter-feeding basket. Ostracoderms lacked the paired (pectoral and pelvic) fins of more advanced fish. In some cases, small spines were present at the points where paired fins develop in higher fishes. In Hemicyclaspis, one sees a pair of anterior, flipper-like structures in lieu of pectoral fins. From Romer, A. S. 1964. The Vertebrate Body. W. B. Saunders. Philadelphia.

[1] Yes, it's time for the Palaeozoic scenes of Life before Man. Or some of them, anyway - if you really want to see a load of trilobites, you're probably Richard Fortey, and I will ignore any comments that claim otherwise. (Also, I can't include everything - otherwise we'd have to rename this blog Love in the Time of Burian, which sounds a bit rubbish.) My bias is most definitely towards vertebrates and, in particular, tetrapods, and the below scene - featuring Ichthyostega - marks their first appearance in the book. This painting is perhaps unique in this book as it combines the elements of the animal-free landscapes with, well, some animals. Burian's skill is in making this scene, filled as it is with flora so utterly different to what we are accustomed to seeing today, look as if he just took a casual stroll out into the country to paint it.

[1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

Organisms are divided into three main groups distinguished by mitochondrial cristal shape (either discoidal, flattened or tubular). Unbroken lines indicate phylogenetic relationships that are firmly supported by available data; broken lines indicate uncertainties in phylogenetic placement, resolution of which will require additional data. Color coding of organismal genus names indicates mitochondrial genomes that have been completely (Table 1), almost completely (Jakoba, Naegleria and Thraustochytrium) or partially (*) sequenced by the OGMP (red), the FMGP (black) or other groups (green). Names in blue indicate those species whose mtDNAs are currently being sequenced by the OGMP or are future candidates for complete sequencing.

Endothermy is the physiological maintenance by a body, of a constant temperature independent of the external environmental temperature. Hair for insulation is correlated to endothermy. Both birds and mammals are endothermic (also called "warm blooded") as opposed to many other vertebrates which are ectothermic (or "cold blooded) and cannot internally generate heat. |

[1] 260 Ma Late Permian UNKNOWN source: http://jan.ucc.nau.edu/~rcb7/260 _Permian_2globes.jpg [2] In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root ''to build.'' Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and small plates that are moving relative to one another as they ride atop hotter, more mobile material. Before the advent of plate tectonics, however, some people already believed that the present-day continents were the fragmented pieces of preexisting larger landmasses (''supercontinents''). The diagrams below show the break-up of the supercontinent Pangaea (meaning ''all lands'' in Greek), which figured prominently in the theory of continental drift -- the forerunner to the theory of plate tectonics.

[1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove.

They were common herbivores during the en:Cretaceous period, and prey to en:therapods such as en:Tyrannosaurus. Spectacular fossils of hadrosaurs have been found, including mummified specimens in which soft tissue was preserved, skin impressions, tracks of footprints, and nest sites that demonstrate the animals had parental care of offspring. Animals are shown to scale. A crisp diagram showing the evolutionary relationships between the tribes of the Hadrosauroidea, with representative individuals shown to scale. Conveys the diversity of the group. Every dinosaur shown has passed review for scientific accuracy at en:Wikipedia:WikiProject Dinosaurs/Image review.

[1] Fig. 4. Our phylogeny differs from and agrees with previous classifications. We merged well-supported (>70% bootstrap values) monophyletic clades at the tips with the same ordinal designation across all three classifications (e.g., 24 species called Passerines). Only higher relationships supported by bootstrap values >50% are shown. Colors are as in Fig. 2. Color bars to the right of the tree show membership in three different classifications: Peters' (25) (left), Sibley and Monroe's (30) (middle), and Livezey and Zusi's (13) (right). Black text within the bars indicates monophyletic orders in our phylogeny, whereas white text within the bars indicates nonmonophyletic orders. Ordinal name codes: ANS (Anseriformes), APO (Apodiformes), APT (Apterygiformes), ARD (Ardeiformes), BAL (Balaenicipitiformes), BUC (Bucerotiformes), CAP (Caprimulgiformes), CAS (Casuariiformes), CHA (Charadriiformes), CIC (Ciconiiformes), CLM (Columbiformes), COL (Coliiformes), COR (Coraciiformes), CRA (Craciformes), CUC (Cuculiformes), FAL (Falconiformes), GAL (Galliformes), GAV (Gaviiformes), GLB (Galbuliformes), GRU (Gruiformes), MUS (Musophagiformes), OPI (Opisthocomiformes), PAS (Passeriformes), PEL (Pelecaniformes), PIC (Piciformes), POD (Podicipediformes), PRO (Procellariiformes), PSI (Psittaciformes), RAL (Ralliformes), RHE (Rheiformes), SPH (Sphenisciformes), STH (Struthioniformes), STR (Strigiformes), TIN (Tinamiformes), TRC (Trochiliformes), TRO (Trogoniformes), TUR (Turniciformes), and UPU (Upupiformes).

[1] Australopithecus squinted at the blue African sky. He had never seen a star in broad daylight before, but he could see one today. White. Piercing. Not as bright as the Sun, yet much more than a full moon. Was it dangerous? He stared for a long time, puzzled, but nothing happened, and after a while he strode across the savanna unconcerned. Millions of years later, we know better. ''That star was a supernova, one of many that exploded in our part of the galaxy during the past 10 million years,'' says astronomer Mark Hurwitz of the University of California-Berkeley. Right: Human ancestors, unconcerned by odd lights in the daytime sky. This image is based on a painting featured in The Economist.

The disappearance of elephants helped kill off Homo erectus, and paved the way for Homo sapiens - modern humans - to take over. Findings from the University of Tel Aviv reveal how important the huge animals were to the diet of early humans - researchers that elephants provided 60 per cent of the meat eaten by Homo erectus.

101,000 YBN [99000 BC] | 594) Homo sapiens move out of Africa into Eurasia. This is the beginning of differences in race within the human species. |
[1] The northern route (along the Danube) is represented by the 'classic' Aurignacian technologies, while the southern (Mediterranean) route is represented by the 'proto-Aurignacian' bladelet technologies (Fig. 3)-with their inferred origins in the preceding early Upper Palaeolithic technologies in the Near East and southeastern Europe. Dates (in thousands of years bp) indicate the earliest radiocarbon dates for these technologies in different areas, expressed in thousands of radiocarbon years before present (bp). (These are likely to underestimate the true (calendar) ages of the sites by between 2,000 and 4,000 yr; see ref. 32). Dashed lines indicate uncertain routes. COPYRIGHTED source: http://www.nature.com/nature/jou rnal/v432/n7016/fig_tab/nature03103_F1.h tml [2] The figure shows the geographical and temporal distribution of hominid populations, based on fossil finds, using different taxonomic schemes. The new finds from Herto4, 5 (H) represent early Homo sapiens. a, This reflects the view that both Neanderthals and modern humans derived from a widespread ancestral species called H. heidelbergensis2. b, However, evidence is growing that Neanderthal features have deep roots in Europe2, 8, so H. neanderthalensis might extend back over 400,000 years. The roots of H. sapiens might be similarly deep in Africa, but this figure represents the alternative view that the ancestor was a separate African species called H. rhodesiensis. Different views of early human evolution are also shown. Some workers prefer to lump the earlier records together and recognize only one widespread species, H. erectus2 (shown in a). Others recognize several species, with H. ergaster and H. antecessor (or H. mauritanicus) in the West, and H. erectus only in the Far East8 (shown in b). Adapted with permission from refs 8, 11. 8.

Belonged to a man - or woman - who inhabited the ancient forests of the Carpathian Mountains in Romania, about 35,000 years ago. The reconstruction of the artist - a face that can be of a male or of a female - is based on the parts of the skull and jaw found in a cave in which it was known that bears hibernate. The facial features indicate the close affinity of these first Europeans with their immediate ancestors Africans, even if it was not yet possible to determine the sex of the person.

[1] Tell-tale signs of 'bit damage' found by researchers in Kazakhstan are evidence that horses were harnessed and may have been ridden as early as 5,500 years ago. Researchers found traces of the use of thong bridles, which are simply leather thongs draped over the gap between the teeth of a horse's lower jaw and knotted under the chin, with the trailing ends acting as the reins. This is a depiction of the use of a rawhide thong bridle on a primitive domesticated horse. The thong loops over the bar, or diastema, between the anterior and cheek teeth, and is knotted below the chin. Credit: Illustration by Sandra Olsen, Carnegie Museum of Natural History Evidence of thong bridle use suggests horses may have been ridden as early as 5,500 years ago.

3,500 YBN [1500 BC] | 6228) Water clock (Clepsydra {KlePSi-Dru}). | Egypt |
[1] clepsydra Egyptian clepsydra An Egyptian clepsydra Also known as a water clock, an instrument in which the discharge of water from a storage tank is monitored in order to measure the passing of time. Clepsydras were used from ancient times until the Renaissance. ''Clepsydra'' is Greek for ''water thief.'' UNKNOWN source: http://www.daviddarling.info/ima ges/Egyptian_clepsydra.jpg [2] The Karnak clepsydra In 1904, archaeological excavations within the ancient temple complex of Karnak in Egypt led to the recovery of fragments of a large conical vessel. The presence of an outlet near the base, plus calibration scales on the interior walls, showed the object to be a classic example of an outflow clepsydra. Figure 6: A full-size reconstruction of the Karnak clepsydraA full-size reconstruction (Fig. 6) may be seen in the New Walk Museum, and illustrates how it could act as a timekeeper independent of the Sun. The vessel is filled with water to a mark near the rim, and then allowed to empty via a narrow jet near the base. With a cylindrical container the rate of flow diminishes as the head of water within the pot decreases, so the water surface drops more slowly with time. The ancient Egyptian designer (Amenhemhet, about 1550 B.C.) has cleverly compensated for this by employing a conical vessel, and trials conducted during the construction of this exhibit have shown that the chosen angle gives rise to an excellent approximation to a linear descent of the water surface. The hieroglyphics covering the outside of the vessel (delineated by Dr. Sarah Symons) do not explain how the water clock was to be used: they are simply traditional decorations in praise of the gods. More information is given alongside the exhibit. UNKNOWN source: http://www.sundials.co.uk/leices ter/fig06.jpg |

Courtesy of the Israel Antiquities Authority (8) The Torah Precepts Scroll This scroll, apparently in the form of a letter, is unique in language, style, and content. Using linguistic and theological analysis, the original text has been dated as one of the earliest works of the Qumran sect. This sectarian polemical document, of which six incomplete manuscripts have been discovered, is commonly referred to as MMT, an abbreviation of its Hebrew name, Miqsat Ma`ase ha-Torah. Together the six fragments provide a composite text of about 130 lines, which probably cover about two-thirds of the original. The initial part of the text is completely missing. Apparently it consisted of four sections: (1) the opening formula, now lost; (2) a calendar of 364 days; (3) a list of more than twenty rulings in religious law (Halakhot), most of which are peculiar to the sect; and (4) an epilogue that deals with the separation of the sect from the multitude of the people and attempts to persuade the addressee to adopt the sect's legal views. The ''halakhot,'' or religious laws, form the core of the letter; the remainder of the text is merely the framework. The calendar, although a separate section, was probably also related to the sphere of ''halakhah.'' These ''halakhot'' deal chiefly with the Temple and its ritual. The author states that disagreement on these matters caused the sect to secede from Israel. References: Strugnell, J., and E. Qimron. Discoveries in the Judaean Desert, X. Oxford, forthcoming.

1,950 YBN [50 AD] | 1078) Steam engine. | Alexandria, Egypt |
[1] Name of Image: Hero's Engine MIX #: 9513982 NIX #: MSFC-9513982 Date of Image: 2004-04-15 Category: Early Rockets Full Description: Legendary characters used the power of mythology to fly through the heavens. About 200 BC, a Greek inventor known as Hero of Alexandria came up with a new invention that depended on the mechanical interaction of heat and water. He invented a rocket-like device called an aeolipile. It used steam for propulsion. Hero mounted a sphere on top of a water kettle. A fire below the kettle turned the water into steam, and the gas traveled through the pipes to the sphere. Two L-shaped tubes on opposite sides of the sphere allowed the gas to escape, and in doing so gave a thrust to the sphere that caused it to rotate.

[1] Fig 1: Byzantine, ivory casket c.1000 (from Museo Nazionale, Florence, Coll. Carrand, No.26) - earliest depiction of a rebec like instrument. Has pear shaped body blending into long narrow neck. There is a definite anchorpoint at the base, with a kind of fleur tailpiece, though the pegs appear to be missing from the depiction (no other anchorpoint is clearly indicated). There are only two strings, and the bow is very long and narrow (though it may simply be the artist trying the show that the bow is perpendicular to the surface of the strings, thus appearing flat when viewed edge on). No sound holes are shown, the soundboard seems to be a distinct, attached piece (possibly a skin covering much like in rababs). This is the instrument in transition. PD source: http://crab.rutgers.edu/~pbutler /ob09.jpg [2] Fig 2: Spanish, Catalan Psalter, c.1050. (''King David and musicians tuning their instruments'' in Bibliotheque Nationale, Paris, MS Lat. 11550, fol. 7v)- Shows a normal pear body shape. Three distinct strings, attached to a triangular tailpiece at the base, and to vertically mounted pegs at the other end. The pegbox is a round disk that appears to be made of the same piece as the neck/body, suggesting that this is a unibody construction. Again a little endpiece or endpeg is indicated. There are two round sound holes set far back on the instrument. The bow is a simple curved bow with end pressure grip (see below). This image is also somewhat suspect from the distortion of the left hand, which has the fingers curling backwards rather than forward as they actually must.

Early in the 16th century, Wan Hu decided to take advantage of China's advanced power and fireworks technology to launch himself into outer space. He had a chair built with 47 ''rockets'' attached. On the day of lift-off, Wan climbed into his rocket chair and held one enormous kite in each hand. The ignition of the 47 fuses caused a huge explosion and sent him into the sky. But unfortunately, he failed to go into orbit and his body smashed into pieces on the ground. UNKNOWN source: http://images.china.cn/images1/2 00710/410673.jpg |

It is engraved on the bottom: ''PHIL{IP}. MELA{NCHTHON}. GOTT. ALEIN. DIE. EHR{E}. 1530'' (Philip Melanchthon, to God alone the glory, 1530). There are very few watches existing today that predate 1550; only two dated examples are known--this one from 1530 and another from 1548. There is no watchmaker's mark, although Nuremberg is considered the birthplace of spherical watches (called ''Nuremberg Eggs''). A single winding kept it running for 12 to 16 hours, and it told time to within the nearest half hour. The perforations in the case permitted one to see the time without opening the watch. This watch was commissioned by the great German reformer and humanist Philip Melanchthon (1497-1560).

Santorio Santorio (1561-1636) made a similar instrument in Venice in 1612. A precursor of the modern thermometer, the thermoscope consists of a glass vessel with a long neck. The vessel was heated with the hands and partially immersed, in an upright position, in a container full of water. When the heat of the hands was taken away, the water was observed to rise in the thermoscope neck. The experiment showed the changes in air density produced by variations in temperature.

[1] Kalthoff 1641 translated with Google from: http://www.earmi.it/A-Enciclopedia/ripet izione.html The first attempt at a mechanical repetition of the shot goes back to the German Peter Kalthoff, which operates in Denmark, who in 1641 invented and built in 1646. It was a rifle with a wheel in the dust reservoir a reservoir for calcium and balls under the barrel, breech block has three rooms that can move sideways. PD source: http://www.earmi.it/A-Encicloped ia/img/Kalthoff.png [2] translated with Google from: http://www.earmi.it/A-Enciclopedia/ripet izione.html In Italy as early as 1572 the Milan Marcantonio Valgrana proposes a rifle capable of firing 4 shots below, but of questionable functionality. This was followed in 600 different mechanical repeating rifles, probably inspired by Kalthoff, but with original solutions. It certainly reminds weapon Berselli James (1660) and other Fresh Water Sebastiano (1619-1692) and the Florentine Michele Lorenzoni (died 1735). These have gone down in history as ''system Lorenzoni'' and are innovative compared to Kalthoff. Tanks for powder and ball (well 25) both are in football, behind a circular rotor driven by an external lever, the gun with the barrel is turned down so that powder and ball fall under gravity, the first movement of lever drops a ball in the barrel where it is retained by a ring of forcing, the second movement takes a dose of dust. There followed many other weapons, but none went beyond the experimental models. The technology of the time did not allow the creation of mechanisms are too delicate and until the invention of the metal cartridge case was difficult to keep the power is communicated by a charge al'altra. The first weapon is the repetition really functioning Paterson Colt revolver of 1936 followed by rifle-revolver .44 Rifle Dragon namely the Whitneyville-Hartford Dragon Colt Revolver of 1847. To solve the problem remained that the number of hits greater than 6-8. The first weapon taken from a manual repeater army Spencer (March 1860) that has a reservoir of calcium and seven cartridges in a loading lever with shutter lock shooting. The cartridge was rimfire cartridge case with copper, was calculated. 13.3 mm which represented an improvement over the previous much larger calibers.

It is a combination of images taken through three filters that are sensitive to red, green and violet light. It shows approximately what Titan would look like to the human eye: a hazy orange globe surrounded by a tenuous, bluish haze. The orange color is due to the hydrocarbon particles which make up Titan's atmospheric haze. This obscuring haze was particularly frustrating for planetary scientists following the NASA Voyager mission encounters in 1980-81. Fortunately, Cassini is able to pierce Titan's veil at infrared wavelengths (see PIA06228). North on Titan is up and tilted 30 degrees to the right. The images to create this composite were taken with the Cassini spacecraft wide angle camera on April 16, 2005, at distances ranging from approximately 173,000 to 168,200 kilometers (107,500 to 104,500 miles) from Titan and from a Sun-Titan-spacecraft, or phase, angle of 56 degrees. Resolution in the images is approximately 10 kilometers per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.

Engraving of the first reaping machine for harvesting grain, invented by Cyrus Hall McCormick (1809-1884) in 1831. As the wheel (at centre) spun, the paddles on it pushed the crop onto a moving cutter bar and knife. This design feature has been retained in modern combine harvesters although McCormick's machine was pulled by horses rather than being pushed. McCormick patented his invention in 1834, made his first sale in 1840 and moved to Chicago in 1847 to begin large-scale production. The six million harvesters he manufactured opened the prairie lands to intensive agriculture, a major factor in America's prosperity.

The bright stars visible are the star cluster Pleiades. The date March 22, 1988 was chosen because the moon occulted stars within the pleides as visible from North America. NOTE: This diagram is geometrically accurate, although not physically possible to see since the moon was not actually above the horizon in half the views. Specifically you can never see the Pleiades from the south pole! They were just picked as extreme views from the earth, the limit of what might be seen from a set of four locations in a square on a great circle and a moon just above the horizon in all four locations.

Aperture for the air to rush from the receiver when the piston has been drawn beyond it. B. Bladder containing the gas to be experimented on. The piston-rod works air-tight in a collar of leathers, and the operation of the pump will be easily understood without further description. If it be required to examine the gas after experiment, a bladder, or tube leading to a pneumatic trough, can be attached at the extrmeity over the valve V.

The machine traveled 120 ft (36.6 m) in 12 seconds at 10:35 a.m. at Kitty Hawk, North Carolina. Orville Wright was at the controls of the machine, lying prone on the lower wing with his hips in the cradle which operated the wing-warping mechanism. Wilbur Wright ran alongside to balance the machine, and just released his hold on the forward upright of the right wing in the photo. The starting rail, the wing-rest, a coil box, and other items needed for flight preparation are visible behind the machine. This was considered ''the first sustained and controlled heavier-than-air, powered flight'' by the Fédération Aéronautique Internationale. Français : L’un des premier vols habités de l’histoire dans un aéronef plus lourd que l’air (36.6 mètres en 12 secondes), par les frères Wright le 17 décembre 1903 à 10h35 sur la plage de Kitty Hawk en Caroline du Nord. Orville est aux commandes, allongé sur le ventre sur l’aile basse et les hanches dans la nacelle qui servait à contrôler le mouvement des ailes ; Wilbur court le long de l’appareil et vient de lacher l’aile droite.

[1] Paul Cornu's helicopter was the first to achieve free flight while carrying a passenger (1907). Credits -National Air and Space Museum, Smithsonian Institution (SI Neg. No. 93-640) The French bicycle maker and engineer Paul Cornu, born in 1881 in Lisieux, France, was the first person to design and build a helicopter that achieved free flight while carrying a passenger. His twin-rotor craft flew for about 20 seconds on November 13, 1907, rising about one foot (0.3 meter) off the ground. A 24-horsepower (18-kilowatt) engine powered the helicopter, which had counter-rotating rotors. The helicopter had no effective means of control and was abandoned after a few flights. Cornu died in 1944. PD source: http://www.centennialofflight.go v/essay/Dictionary/Cornu/DI18G1.jpg [2] Paul Cornu in his first helicopter in 1907. Note that he is sitting between the two rotors, which rotated in opposite directions to cancel torque. This helicopter was the first flying machine to have risen from the ground using rotor blades instead of wings.

[1] Pioneer 11 Image of Saturn and Its Moon Titan {ULSF: Titan is at the upper left} The Pioneer 11 spacecraft launched from Cape Canaveral forty years ago, on April 5, 1973. Pioneer 11's path through Saturn's outer rings took it within 21,000 km of the planet, where it discovered two new moons (almost smacking into one of them in September 1979) and a new ''F'' ring. The spacecraft also discovered and charted the magnetosphere, magnetic field and mapped the general structure of Saturn's interior. The spacecraft's instruments measured the heat radiation from Saturn's interior and found that its planet-sized moon, Titan, was too cold to support life. This image from Pioneer 11 shows Saturn and its moon Titan. The irregularities in ring silhouette and shadow are due to technical anomalies in the preliminary data later corrected. At the time this image was taken, Pioneer was 2,846,000 km (1,768,422 miles) from Saturn. › NASA Celebrates Four Decades of Plucky Pioneer 11 Image credit: NASA Ames PD source: http://www.nasa.gov/images/conte nt/739507main_739460main_AC79-9107.3_160 0-1200.jpg [2] Pioneer 10 PD source: http://quest.nasa.gov/sso/cool/p ioneer10/graphics/lasher/slide4.jpg |

[1] Description Uranus.jpg English: NASA photo of Uranus taken by Voyager 2. Caption: This pictures of Uranus was compiled from images recorded by Voyager 2 on January 10, 1986, when the NASA spacecraft was 18 million kilometers (11 million miles) from the planet. The images were obtained by Voyager's narrow-angle camera; the view is toward the planet's pole of rotation, which lies just left of center. The picture has been processed to show Uranus as human eyes would see it from the vantage point of the spacecraft. The dark shading of the upper right edge of the disk is the terminator, or day-night boundary. The blue-green appearance of Uranus results from methane in the atmosphere; this gas absorbs red wavelengths from the incoming sunlight, leaving the predominant bluish color seen here. Images shuttered through different color filters were added and manipulated by computer, greatly enhancing the low-contrast details in the original images. The planet reveals a dark polar hood surrounded by a series of progressively lighter convective bands. The banded structure is real, though exaggerated here. The Voyager project is managed for NASA by the Jet Propulsion Laboratory.

[1] A picture of Neptune taken by Voyager 2, showing off the Great Dark Spot which has since disappeared from the planet's surface. Original Caption Released with Image: During August 16 and 17, 1989, the Voyager 2 narrow-angle camera was used to photograph Neptune almost continuously, recording approximately two and one-half rotations of the planet. These images represent the most complete set of full disk Neptune images that the spacecraft will acquire. This picture from the sequence shows two of the four cloud features which have been tracked by the Voyager cameras during the past two months. The large dark oval near the western limb (the left edge) is at a latitude of 22 degrees south and circuits Neptune every 18.3 hours. The bright clouds immediately to the south and east of this oval are seen to substantially change their appearances in periods as short as four hours. The second dark spot, at 54 degrees south latitude near the terminator (lower right edge), circuits Neptune every 16.1 hours. This image has been processed to enhance the visibility of small features, at some sacrifice of color fidelity.

High-resolution surface images and measurements made by NEAR's Laser Rangefinder (NLR) have been combined into the above visualization based on the derived 3D model of the tumbling space rock. NEAR allowed scientists to discover that Eros is a single solid body, that its composition is nearly uniform, and that it formed during the early years of our Solar System. Mysteries remain, however, including why some rocks on the surface have disintegrated. On 2001 February 12, the NEAR mission drew to a dramatic close as it was crash landed onto the asteroid's surface, surviving well enough to return an analysis of the composition of the surface regolith. In December of 2002, NASA made an unsuccessful attempt to communicate with the spacecraft after it spent 22 months resting on the asteroid's surface. NEAR will likely remain on the asteroid for billions of years as a monument to human ingenuity at the turn of the third millennium.

[1] Hitachi Develops a New RFID with Embedded Antenna µ-Chip --Makes Possible Wireless Links that Work Using Nothing More Than a 0.4mm X 0.4mm Chip, One of the World's Smallest ICs-- A New RFID with Embedded Antenna MU-Chip Tokyo, September 2, 2003-Hitachi, Ltd. (TSE: 6501) today announced that it has developed a new version of its RFID µ-Chip embedding an antenna. When using Hitachi's original µ-Chip, one of the world's smallest RFID ICs measuring only 0.4mm X 0.4mm, an external antenna must be attached to the chip to allow external devices to read the 128-bit ID number stored in its ROM (Read-Only-Memory). This newly developed version, however, features an internal antenna, enabling chips to employ the energy of incoming electrical waves to wirelessly transmit its ID number to a reader. The 0.4mm X 0.4mm chip can thus operate entirely on its own, making it possible to use µ-Chip as RFID IC tags without the need to attach external devices. This breakthrough opens the door to using µ-Chips as RFID IC tags in extremely minute and precise applications that had been impractical until now. For example, the new µ-Chip can be easily embedded in bank notes, gift certificates, documents and whole paper media etc. The µ-Chip, announced by Hitachi in July 2001, is one of the world's smallest IC chips at 0.4mm X 0.4mm. The chip data is recorded in read-only memory during the semiconductor production process, and therefore cannot be rewritten, thus guaranteeing its authenticity. Applications of the µ-Chip include a system for managing the SCM materials on sites, and entrance tickets for Expo 2005 Aichi Japan which opens on March 25, 2005. The primary features of this revolutionary µ-Chip are as follows. (1) A RFID IC chip measuring only 0.4mm X 0.4mm with built-in antenna Despite its extremely small size, this µ-Chip has a built-in antenna to permit contactless communications (at very close proximity) with other devices without using an external antenna. (2) No need for special manufacturing equipment The antenna is formed using bump-metalization technology (used to create the electrical contacts of an IC), a process already widely used by semiconductor manufacturers, thus eliminating any need for specialized equipment. (3) Complete compatibility with conventional µ-Chip With ID numbers and support systems that are fully compatible with those of existing µ-Chip, the new chip is fully compatible with all systems that use current µ-Chip technology. Hitachi plans to develop numerous markets for this chip that take full advantage of its outstanding features. Embedding the chip in securities, identification and other valuable documents such as vouchers offers a highly sophisticated means of preventing counterfeiting. Another high-potential application is agricultural products, where the chips can help ensure the safety of food by providing traceability of ingredients. Additionally, the chips can be embedded in business forms to automate logistics systems and many other business processes.

[1] Credit: Zettl Research Group LBNL, University of California, Berkley Electric Drives - Special Purpose Motors (Description and Applications) Motor Construction Special purpose designs have been developed to solve a wide range of drive problems. Some common examples are included here. Integrated Starter Generator (ISG) The electronically controlled integrated starter generator used in mild hybrid electric vehicles (HEVs) combines the automotive starter and alternator into a single machine. The conventional starter is a low speed, high current DC machine, while the alternator is a variable speed 3 phase AC machine. The ISG has four important functions in a hybrid vehicle application It enables the ''start-stop'' function, turning off the engine when the vehicle is stationary saving fuel. It generates the electrical energy to power all the electrical ancillaries. It provides a power boost to assist the engine when required, permitting smaller engines for similar performance. In some configurations it recuperates energy from regenerative braking. In a typical implementation (below), the ISG is a short axis, large diameter ''pancake'' shaped switched reluctance machine mounted directly on the end of the engine crankshaft between the engine and the clutch in the gearbox bell housing. Image source Long, Schofield, Howe, Piron & McClelland ''Design of a Switched Reluctance Machine for Extended Speed Operation'' IMEDC June 2003 The ISG is a bi-directional energy converter acting as a motor when powered by the battery or a generator when driven by the engine. The system voltage in a mild HEV is 42 Volts which means that, for the same cranking power as a 12 Volt machine, the starter current can be reduced. Typical power throughput is between 5kW and 15 kW with a possible peak power of 70 kW for cold cranking.. The brushless ISG design eliminates one rotating machine completely as well as the associated commutator and brushes from the DC machine and the sliprings and brushes from the AC machine. The starter solenoid, the Bendix ring (starter gear) and the pulley or gear drive to the alternator are also no longer needed and because of the higher system voltage, the diameter and weight of the copper cabling is also reduced substantially. The savings however come at a cost. The system must be integrated with several subsystems as follows An AC/DC converter to rectify the generator output voltage. A DC/DC converter to supply the vehicle's electrical power system voltages. Power electronics and software to control the ISG current, voltage, speed, torque and temperature as appropriate. An overall energy management system integrated with the vehicle's engine, battery and brakes. Larger versions of this construction are also used in full hybrid electric vehicles. The switched reluctance machine with its simple rotor of inert iron is very robust, able to operate at high speed and to withstand the harsh operating conditions in the engine compartment. History Outer Rotor Motors There are many designs using this construction, mostly for small sizes. Two examples of low power motors are shown below. High power versions are used for ''in wheel'' automotive applications. Inside Out Motor These are permanent magnet motors with the moving magnets arranged around the periphery of a multi pole fixed stator carrying the field windings. Used for automotive drive systems including in-wheel motors. Low power versions used in small cooling fans and direct drive record player turntables. Toroidal Coil Motor This is an ''inside out'' brushless permanent magnet motor with a toroidal wound stator covered by a cup shaped permanent magnet outer rotor. Because of the low inertia and friction free rotor, the toroidal motor is capable of speeds up to 25,000 RPM. Suitable for low power applications it is used for example to drive the polygonal rotating mirrors which are mounted directly on the rotor in laser printers. Linear Motors In most cases the linear motor can be considered as a conventional rotary motor with both the stator and the rotor split and rolled out flat. The same electromagnetic forces apply and these have been employed in similar classes of AC and DC machines. Except for traction motors the travel of the motor armature is usually quite short. Linear Stepping Motors The most common application is the stepping motor. Stator poles are laid out along the track and excited by windings fed from a pulsed DC source. Permanent magnets forming the armature are held in the carriage. The carriage moves along the track in response to pulses sent to the the stator windings in much the same way as the rotor turns in a brushless DC motor. Closed loop control is possible by mounting a position sensor on the carriage. Despite the elegance of the linear motor, linear motion is more often provided by the less expensive and more mundane method of using a rotary stepping motor driving a lead screw. Maglev Traction Motors The principle of the linear induction motor is used to propel high speed Maglev (Magnetic Levitation) trains which float on a magnetic field created by electromagnets in the trackbed under the train . A separate set of trackside guidance magnets is used to control the lateral position of the train relative to the track. Thus the maglev train uses electromagnetic forces for three different tasks, to suspend, to guide and to propel the train. Maglev trains have been developed in several countries of the world using a variety of configurations. Examples of the essential features are described below. Propulsion The train has no onboard motor. Electromagnets in the trackbed are excited in sequence creating a linear rather than a rotating field. By transformer action, the trackbed coils induce currents in coils on board the train which are used to energise powerful electromagnets. The Lorentz force between the trackbed currents and the the onboard electromagnets causes the magnets to be propelled along by the moving field. The principles involved are very similar to those of the induction motor but with the static and moving parts interchanged. See diagram below. For illustrative purposes the track can be likened to a ladder formed by the unrolled squirrel cage rotor of the induction motor. In this case however it is fixed and it supplies the moving field. Currents are induced in the train's electromagnets which are equivalent to the stator poles of the induction motor but in this case the magnets are free to move. In practical designs the trackbed currents are actually provided in a series of individual coils laid along the track. Levitation Various levitation schemes are used. The force holding the train aloft can be created by the magnetic repulsion between the same electromagnets on the track and the onboard electromagnets in the train which are used for propulsion. The train's levitating magnets are powered by direct current supplied by a battery which is kept charged by an induction generator taking its power from the currents induced by the trackbed coils in the onboard generator coils. In the diagram above, when the magnet is directly above the current carrying conductor as shown, the magnetic forces (north and south poles) from the two adjacent current loops cancel out and there is no lift. If however the magnet is moving very quickly over the coils, it will reach a position over like, repulsive, poles (north poles in the diagram) which are displaced from the attractive south poles so that the net effect is a force repelling the magnet away from the track. This is only possible because the current in the trackbed magnets lags the voltage due to the inductance of the windings, creating a delay in the build up of the balanced field by which time the magnet has moved into the adjacent region where there is a net repulsive force. This effect only happens when the magnet on the train is moving at high speed across the trackbed magnets. Thus the train needs to be in motion for this system to work and the train needs wheels for support as it accelerates from rest and when it is slowing to a halt. Alternatively levitation can be provided by separate windings. The train's levitation magnets protrude from the side of the train and run between pairs of vertically separated electromagnets in guideways at each side of the train, rather than in the trackbed. This arrangement creates an attractive force above the train's magnets combined with a repulsive force beneath the train's magnets to provide the levitating force. Guidance For guidance the train uses magnetic fields provided by a separate set of weaker magnets along each side of the train. Similar in principle to the levitation magnets they are used to control the lateral position of the train relative to the track. Excitation of the trackside magnets is arranged such that only the section under the train is active. As the train moves along the track between sections the current to the previous section is switched off and the current to the next section is switched on pulling the train along. This serves the dual purpose of avoiding losses by energising only the section of track directly under the train and at the same time, since the power to the rest of the track is switched off, it provides security against electric shock to anybody near to the track and avoids the possibility of accidentally short circuiting the system by dropping rubbish onto live conductors. Very high armature currents of thousands of amps or more are involved and some designs use high temperature superconductors ( HTS ) in the onboard magnets, cooled with liquid nitrogen or helium to minimise the resistive losses. As might be expected some sophisticated control systems are needed to keep everything on track. History Axial Field Motors Axial field motors have been developed for applications which require short, flat, ''pancake'' construction. Printed Circuit (PCB) or ''Pancake'' Motor The printed circuit motor is an example of an ironless or coreless motor with several unique features. The pancake construction uses an axial magnetic field to achieve the short flat construction. Radial field PCB motors are also possible. Construction The rotor windings are printed, stamped or welded onto a thin, disc shaped glass fibre circuit board which rotates in the air gap between pairs of permanent magnets arranged around the periphery of the disk. The windings fan out in a series of radial loops around the surface of the disk. The magnets are arranged alternatively north and south so that the magnetic fields in the air gaps of adjacent magnet pairs are in opposite directions. The magnets are held in place by two iron end caps in a compact ''pancake'' shaped block to complete the magnetic circuit. Current is fed to the rotor windings via brushes through precious metal commutator segments printed on the disc. Operating Principle Traditional electric motors have a radial magnetic field or flux with the rotor current flowing axially along the length of the rotor. In typical printed circuit motors the construction is reversed. The magnetic field is axial (oriented along the axis of the machine) and the current flows radially from the axis to the edge of the disc and back again. A tangential force on the disk is created by the current passing through the magnetic fields in the air gaps between the pole pairs of the permanent magnets. So that the return current does not cancel out the effect of the outgoing current, the return wire is physically separated or displaced to one side from the outgoing wire by the width of the magnet. In this way it interacts with the magnetic field of the adjacent magnet which is in the opposite direction and thus reinforces the tangential force on the disk. In many ways it is similar to Faraday's 1831disk or homopolar motor which used a single magnet and was driven by a unidirectional current fed by brushes at the centre and on the periphery of the disk. Applications The printed circuit motor is a very compact and light weight design making it useful in confined spaces. Since the rotor does not have drag a lump of iron around, it has very low inertia and can run up to speed very quickly. Because of the many commutator segments and the low current capability of the windings, the PCB motor is only suitable for low power applications and is not suitable for continuous operation. It is however ideal for servo systems and industrial controls and automotive applications such as electric window winders. Micro-motors (Micro-ElectroMechanical Systems - MEMS) Electrostatic Motor The motor shown below is an example of semiconductor manufacturing technology used to fabricate very small mechanical components. It measures 100 microns across, or about the width of a human hair. Similar in principle to a reluctance motor, it depends on electrostatic attraction, rather than magnetic attraction, between the stator and rotor poles. Because the dimensions are so tiny, very high electric fields can be built up with only a few volts between the motor poles. Fan Long-Shen, Tai Yu-Chong and Richard S.

Electron Devices The motor is not assembled from individual components.

Micromachined micromotors can be monolithically integrated together with the necessary CMOS drive circuits, containing oscillators, frequency dividers and counters, and transistors for the drive circuit all on one silicon chip. Common uses include defense/munitions applications, computer hard drives, optics, sensors and actuators. History Nano-motors (Nano-ElectroMechanical Systems - NEMS) Electrostatic Motor Even smaller motors have been made using nanotechnology. An example is shown below. It consists of a tiny gold slab rotor, about 100 nm square, mounted on concentric carbon nanotubes. The outer tube carries the rotor, driven by electrostatic electrodes, rotating around an inner tube which acts as a supporting shaft. By applying voltage pulses of up to 5 Volts between the rotor plate and stators, the position, speed and direction of rotation of the rotor can be controlled. It measures about 500 nanometers across, 300 times smaller than the diameter of a human hair. UNKNOWN source: http://www.mpoweruk.com/images/n ems.gif [2] Credit: Zettl Research Group LBNL, University of California, Berkley Electric Drives - Special Purpose Motors (Description and Applications) Motor Construction Special purpose designs have been developed to solve a wide range of drive problems. Some common examples are included here. Integrated Starter Generator (ISG) The electronically controlled integrated starter generator used in mild hybrid electric vehicles (HEVs) combines the automotive starter and alternator into a single machine. The conventional starter is a low speed, high current DC machine, while the alternator is a variable speed 3 phase AC machine. The ISG has four important functions in a hybrid vehicle application It enables the ''start-stop'' function, turning off the engine when the vehicle is stationary saving fuel. It generates the electrical energy to power all the electrical ancillaries. It provides a power boost to assist the engine when required, permitting smaller engines for similar performance. In some configurations it recuperates energy from regenerative braking. In a typical implementation (below), the ISG is a short axis, large diameter ''pancake'' shaped switched reluctance machine mounted directly on the end of the engine crankshaft between the engine and the clutch in the gearbox bell housing. Image source Long, Schofield, Howe, Piron & McClelland ''Design of a Switched Reluctance Machine for Extended Speed Operation'' IMEDC June 2003 The ISG is a bi-directional energy converter acting as a motor when powered by the battery or a generator when driven by the engine. The system voltage in a mild HEV is 42 Volts which means that, for the same cranking power as a 12 Volt machine, the starter current can be reduced. Typical power throughput is between 5kW and 15 kW with a possible peak power of 70 kW for cold cranking.. The brushless ISG design eliminates one rotating machine completely as well as the associated commutator and brushes from the DC machine and the sliprings and brushes from the AC machine. The starter solenoid, the Bendix ring (starter gear) and the pulley or gear drive to the alternator are also no longer needed and because of the higher system voltage, the diameter and weight of the copper cabling is also reduced substantially. The savings however come at a cost. The system must be integrated with several subsystems as follows An AC/DC converter to rectify the generator output voltage. A DC/DC converter to supply the vehicle's electrical power system voltages. Power electronics and software to control the ISG current, voltage, speed, torque and temperature as appropriate. An overall energy management system integrated with the vehicle's engine, battery and brakes. Larger versions of this construction are also used in full hybrid electric vehicles. The switched reluctance machine with its simple rotor of inert iron is very robust, able to operate at high speed and to withstand the harsh operating conditions in the engine compartment. History Outer Rotor Motors There are many designs using this construction, mostly for small sizes. Two examples of low power motors are shown below. High power versions are used for ''in wheel'' automotive applications. Inside Out Motor These are permanent magnet motors with the moving magnets arranged around the periphery of a multi pole fixed stator carrying the field windings. Used for automotive drive systems including in-wheel motors. Low power versions used in small cooling fans and direct drive record player turntables. Toroidal Coil Motor This is an ''inside out'' brushless permanent magnet motor with a toroidal wound stator covered by a cup shaped permanent magnet outer rotor. Because of the low inertia and friction free rotor, the toroidal motor is capable of speeds up to 25,000 RPM. Suitable for low power applications it is used for example to drive the polygonal rotating mirrors which are mounted directly on the rotor in laser printers. Linear Motors In most cases the linear motor can be considered as a conventional rotary motor with both the stator and the rotor split and rolled out flat. The same electromagnetic forces apply and these have been employed in similar classes of AC and DC machines. Except for traction motors the travel of the motor armature is usually quite short. Linear Stepping Motors The most common application is the stepping motor. Stator poles are laid out along the track and excited by windings fed from a pulsed DC source. Permanent magnets forming the armature are held in the carriage. The carriage moves along the track in response to pulses sent to the the stator windings in much the same way as the rotor turns in a brushless DC motor. Closed loop control is possible by mounting a position sensor on the carriage. Despite the elegance of the linear motor, linear motion is more often provided by the less expensive and more mundane method of using a rotary stepping motor driving a lead screw. Maglev Traction Motors The principle of the linear induction motor is used to propel high speed Maglev (Magnetic Levitation) trains which float on a magnetic field created by electromagnets in the trackbed under the train . A separate set of trackside guidance magnets is used to control the lateral position of the train relative to the track. Thus the maglev train uses electromagnetic forces for three different tasks, to suspend, to guide and to propel the train. Maglev trains have been developed in several countries of the world using a variety of configurations. Examples of the essential features are described below. Propulsion The train has no onboard motor. Electromagnets in the trackbed are excited in sequence creating a linear rather than a rotating field. By transformer action, the trackbed coils induce currents in coils on board the train which are used to energise powerful electromagnets. The Lorentz force between the trackbed currents and the the onboard electromagnets causes the magnets to be propelled along by the moving field. The principles involved are very similar to those of the induction motor but with the static and moving parts interchanged. See diagram below. For illustrative purposes the track can be likened to a ladder formed by the unrolled squirrel cage rotor of the induction motor. In this case however it is fixed and it supplies the moving field. Currents are induced in the train's electromagnets which are equivalent to the stator poles of the induction motor but in this case the magnets are free to move. In practical designs the trackbed currents are actually provided in a series of individual coils laid along the track. Levitation Various levitation schemes are used. The force holding the train aloft can be created by the magnetic repulsion between the same electromagnets on the track and the onboard electromagnets in the train which are used for propulsion. The train's levitating magnets are powered by direct current supplied by a battery which is kept charged by an induction generator taking its power from the currents induced by the trackbed coils in the onboard generator coils. In the diagram above, when the magnet is directly above the current carrying conductor as shown, the magnetic forces (north and south poles) from the two adjacent current loops cancel out and there is no lift. If however the magnet is moving very quickly over the coils, it will reach a position over like, repulsive, poles (north poles in the diagram) which are displaced from the attractive south poles so that the net effect is a force repelling the magnet away from the track. This is only possible because the current in the trackbed magnets lags the voltage due to the inductance of the windings, creating a delay in the build up of the balanced field by which time the magnet has moved into the adjacent region where there is a net repulsive force. This effect only happens when the magnet on the train is moving at high speed across the trackbed magnets. Thus the train needs to be in motion for this system to work and the train needs wheels for support as it accelerates from rest and when it is slowing to a halt. Alternatively levitation can be provided by separate windings. The train's levitation magnets protrude from the side of the train and run between pairs of vertically separated electromagnets in guideways at each side of the train, rather than in the trackbed. This arrangement creates an attractive force above the train's magnets combined with a repulsive force beneath the train's magnets to provide the levitating force. Guidance For guidance the train uses magnetic fields provided by a separate set of weaker magnets along each side of the train. Similar in principle to the levitation magnets they are used to control the lateral position of the train relative to the track. Excitation of the trackside magnets is arranged such that only the section under the train is active. As the train moves along the track between sections the current to the previous section is switched off and the current to the next section is switched on pulling the train along. This serves the dual purpose of avoiding losses by energising only the section of track directly under the train and at the same time, since the power to the rest of the track is switched off, it provides security against electric shock to anybody near to the track and avoids the possibility of accidentally short circuiting the system by dropping rubbish onto live conductors. Very high armature currents of thousands of amps or more are involved and some designs use high temperature superconductors ( HTS ) in the onboard magnets, cooled with liquid nitrogen or helium to minimise the resistive losses. As might be expected some sophisticated control systems are needed to keep everything on track. History Axial Field Motors Axial field motors have been developed for applications which require short, flat, ''pancake'' construction. Printed Circuit (PCB) or ''Pancake'' Motor The printed circuit motor is an example of an ironless or coreless motor with several unique features. The pancake construction uses an axial magnetic field to achieve the short flat construction. Radial field PCB motors are also possible. Construction The rotor windings are printed, stamped or welded onto a thin, disc shaped glass fibre circuit board which rotates in the air gap between pairs of permanent magnets arranged around the periphery of the disk. The windings fan out in a series of radial loops around the surface of the disk. The magnets are arranged alternatively north and south so that the magnetic fields in the air gaps of adjacent magnet pairs are in opposite directions. The magnets are held in place by two iron end caps in a compact ''pancake'' shaped block to complete the magnetic circuit. Current is fed to the rotor windings via brushes through precious metal commutator segments printed on the disc. Operating Principle Traditional electric motors have a radial magnetic field or flux with the rotor current flowing axially along the length of the rotor. In typical printed circuit motors the construction is reversed. The magnetic field is axial (oriented along the axis of the machine) and the current flows radially from the axis to the edge of the disc and back again. A tangential force on the disk is created by the current passing through the magnetic fields in the air gaps between the pole pairs of the permanent magnets. So that the return current does not cancel out the effect of the outgoing current, the return wire is physically separated or displaced to one side from the outgoing wire by the width of the magnet. In this way it interacts with the magnetic field of the adjacent magnet which is in the opposite direction and thus reinforces the tangential force on the disk. In many ways it is similar to Faraday's 1831disk or homopolar motor which used a single magnet and was driven by a unidirectional current fed by brushes at the centre and on the periphery of the disk.

[1] Once built and populated, a colony with excellent recycling will need only a few materials to replace leaks and losses. However, a great deal of materials will be needed to build a space colony, particularly shielding. If a colony expands, builds new colonies, or builds solar power satellites or other export products, a lot of material will be necessary. There are several sources of materials to consider: Earth, the Moon, asteroids, other planets, and other moons. All the materials necessary for space colonies are available on Earth. In addition, manufacturing facilities to provide finished products are readily available.

Stretching a supercoil of DNA between its lower pair of robot arms, the nanomachine gently pulls the unwound strand through an opening in its prow for analysis. Upper arms, meanwhile, detach regulatory proteins from the chain and place them in an intake port. The molecular structures of both DNA and proteins are compared to information stored in the database of a larger nanocomputer positioned outside the nucleus and connected to the cell-repair ship by a communications link. Irregularities found in either structure are corrected and the proteins reattached to the DNA chain, which re-coils into its original form. With a diameter of only 50 nanometers, the repair vessel would be smaller than most bacteria and viruses, yet capable of therapies and cures well beyond the reach of present-day physicians. With trillions of these machines coursing through a patient's bloodstream, ''internal medicine'' would take on new significance. Disease would be attacked at the molecular level, and such maladies as cancer, viral infections and arteriosclerosis could be wiped out. Copyright Info: © Copyright 1989 by Time-Life Books Inc.

[1] {ULSF: adapted by Ted Huntington from below:} Description This picture is an artist's impression showing how the binary star system of Sirius A and its diminutive blue companion, Sirius B, might appear to an interstellar visitor. The large, bluish-white star Sirius A dominates the scene, while Sirius B is the small but very hot and blue white-dwarf star on the right. The two stars revolve around each other every 50 years. White dwarfs are the leftover remnants of stars similar to our Sun. The Sirius system, only 8.6 light-years from Earth, is the fifth closest stellar system known. Sirius B is faint because of its tiny size. Its diameter is only 7,500 miles (about 12 thousand kilometres), slightly smaller than the size of our Earth. The Sirius system is so close to Earth that most of the familiar constellations would have nearly the same appearance as in our own sky. In this rendition, we see in the background the three bright stars that make up the Summer Triangle: Altair, Deneb, and Vega. Altair is the white dot above Sirius A; Deneb is the dot to the upper right; and Vega lies below Sirius B. But there is one unfamiliar addition to the constellations: our own Sun is the second-magnitude star, shown as a small dot just below and to the right of Sirius A.

[1] Adapted from: The Missing Craters of Asteroid Itokawa Credit & Copyright: ISAS, JAXA Explanation: Where are the craters on asteroid Itokawa? No one knows. The Japanese robot probe Hayabusa recently approached the Earth-crossing asteroid and is returning pictures showing a surface unlike any other Solar System body yet photographed -- a surface possibly devoid of craters. One possibility for the lack of common circular indentations is that asteroid Itokawa is a rubble pile -- a bunch of rocks and ice chunks only loosely held together by a small amount of gravity. If so, craters might be filled in whenever the asteroid gets jiggled by a passing planet -- Earth in this case. Alternatively, surface particles may become electrically charged by the Sun, levitate in the microgravity field, and move to fill in craters. Over the weekend, Hayabusa lowered itself to the surface of the strange asteroid in an effort to study the unusual body and collect surface samples that could be returned to Earth in 2007.

800 YAN [2800 AD] | 4628) Humans change the motion of a moon. (A moon of Jupiter). | Jupiter |
[1] A map of Io This map of Io was created by taking three relatively low resolution Voyager 2 maps of Io and composing them into a color map. These maps were taken from this FTP site. Each of the three original maps was created from images taken through differently colored filters. I then replaced the luminosity channel of the color map with a very high resolution grayscale map from the above site. That map was created from Voyager 1 photos. The result was impressive despite the fact that Io changed somewhat between the two Voyager flybys (it is after all the most volcanically active body in the solar system !). I then removed the most prominent seams and color discontinuities. Some seams still remain (I was more lazy when creating this map than e.g. the Europa map ;) but remarkably they are usually not visible in 3D renderings except for renderings showing Io from a close range. I may remove these defects some day. Finally I replaced small, black areas near the poles (where no imagery is available) with fictional data created by cloning adjacent areas. This map is aesthetically better than the ones at David Seal's site and also of higher resolution but the color is probably less realistic than in his ''yellowish'' map. His maps are also more realistic in the sense that there is no fictional data at the poles, they are simply blank. Click the map below to view the 2880x1440 pixel (442 KB JPG) full size map. Actually my original map is 5760x2880 pixels but I do not have space for such a monster here.

[1] International Space Station crew members are trained to observe and document dynamic events on the Earth’s surface, such as hurricanes, forest fires, and volcanic eruptions. Their observations provide scientists and the general public a different perspective on these events. Earlier this week, astronauts in the crew of the ISS-5 mission were able to observe Mt. Etna’s spectacular eruption, and photograph the details of the eruption plume as well as smoke from fires triggered by the lava as it flowed down the 11,000-foot mountain. This image is looking obliquely to the southeast over the island of Sicily. A wider view (ISS005-E-19016) shows the ash plume curving out toward the horizon, caught first by low-level winds blowing to the southeast, and to the south toward Africa at higher altitudes. Ashfall was reported in Libya, more than 350 miles away. The lighter-colored plumes downslope and north of the summit (see detailed view, ISS005-E-19024) are produced by gas emissions from a line of vents on the mountain’s north flank. The detailed image provides a three-dimensional profile of the eruption plume. This was one of Etna’s most vigorous eruptions in years. The eruption was triggered by a series of earthquakes on October 27. These images were taken on October 30, 2002. Sicilans have learned to live with Etna’s eruptions. Although schools were closed and air traffic was diverted because of the ash, no towns or villages were threatened by the lava flow. Astronaut photographs ISS005-E-19016 and ISS005-E-19024 were taken on October 30, 2002, at about 11:30 GMT and are provided by the Earth Sciences and Image Analysis Laboratory at Johnson Space Center. Additional images taken by astronauts and cosmonauts can be viewed at the NASA-JSC Gateway to Astronaut Photography of Earth.

The cluster, which is found to be only 500 000 years old — a blink of an eye in the Universe’s history — resides at the outskirts of the central region of the Carina Nebula, located some 8000 light-years away towards the constellation of Carina (the Keel). Trumpler 14 is not only the youngest, but also one of the most populous clusters within the nebula. Astronomers counted about 2000 stars in the very central parts of this cluster. The MAD instrument allows astronomers to obtain very sharp images over a wide area and this image is the adaptive optics image that so far covers the widest area on the sky. The field of view is about 2 arcminutes across and the image is based on data obtained through two different filters (K and H).

[1] Humans touch advanced life of another star by Ted Huntington with background image of: Double Cluster in Perseus Credit & Copyright: Roth Ritter (Dark Atmospheres) Explanation: Some 7,000 light-years away, this pair of open or galactic star clusters is an easy binocular target, a lovely starfield in the northern constellation Perseus. Also visible to the unaided eye from dark sky areas, it was cataloged in 130 BC by Greek astronomer Hipparchus. Now known as h and chi Persei, or NGC 869(above right) and NGC 884, the clusters themselves are separated by only a few hundred light-years and contain stars much younger and hotter than the Sun. In addition to being physically close together, the clusters' ages based on their individual stars are similar - evidence that both clusters were likely a product of the same star-forming region.

[1] Open Star Cluster M38 Credit & Copyright: NOAO, AURA, NSF Explanation: Open cluster M38 can be seen with binoculars toward the constellation of Auriga. M38 is considered an intermediately rich open cluster of stars, each of which is about 200 million years old. Located in the disk of our Milky Way galaxy, M38 is still young enough to house many bright blue stars, although it's brightest star is a yellow giant shining 900 times brighter than our Sun. The cluster spans roughly 25 light-years and lies about 4000 light-years away. M38, pictured above, is found only about 2.5 degrees northwest of open cluster M36. Loosely bound by gravity, open clusters spread out over time as they orbit the galactic center and their member stars slowly escape. PD source: http://apod.nasa.gov/apod/image/ 0301/m38_noao.jpg |

[1] Hyades for the Holidays Image Credit & Copyright: Jerry Lodriguss (Catching the Light) Explanation: Recognized since antiquity and depicted on the shield of Achilles according to Homer, stars of the Hyades cluster form the head of the constellation Taurus the Bull. Their general V-shape is anchored by Aldebaran, the eye of the Bull and by far the constellation's brightest star. Yellowish in appearance, red giant Aldebaran is not a Hyades cluster member, though. Modern astronomy puts the Hyades cluster 151 light-years away making it the nearest established open star cluster, while Aldebaran lies at less than half that distance, along the same line-of-sight. Along with colorful Hyades stars, this stellar holiday portrait locates Aldebaran just below center, as well as another open star cluster in Taurus, NGC 1647 at the left, some 2,000 light-years or more in the background. Just slide your cursor over the image to identify the stars. The central Hyades stars are spread out over about 15 light-years. Formed some 800 million years ago, the Hyades star cluster may share a common origin with M44 (Praesepe), a naked-eye open star cluster in Cancer, based on M44's motion through space and remarkably similar age.

50,000 YAN [52000 AD] | 4658) All asteroids are consumed. |
[1] Adapted from: The Missing Craters of Asteroid Itokawa Credit & Copyright: ISAS, JAXA Explanation: Where are the craters on asteroid Itokawa? No one knows. The Japanese robot probe Hayabusa recently approached the Earth-crossing asteroid and is returning pictures showing a surface unlike any other Solar System body yet photographed -- a surface possibly devoid of craters. One possibility for the lack of common circular indentations is that asteroid Itokawa is a rubble pile -- a bunch of rocks and ice chunks only loosely held together by a small amount of gravity. If so, craters might be filled in whenever the asteroid gets jiggled by a passing planet -- Earth in this case. Alternatively, surface particles may become electrically charged by the Sun, levitate in the microgravity field, and move to fill in craters. Over the weekend, Hayabusa lowered itself to the surface of the strange asteroid in an effort to study the unusual body and collect surface samples that could be returned to Earth in 2007.

[1] Adapted from: Description This picture is an artist's impression showing how the binary star system of Sirius A and its diminutive blue companion, Sirius B, might appear to an interstellar visitor. The large, bluish-white star Sirius A dominates the scene, while Sirius B is the small but very hot and blue white-dwarf star on the right. The two stars revolve around each other every 50 years. White dwarfs are the leftover remnants of stars similar to our Sun. The Sirius system, only 8.6 light-years from Earth, is the fifth closest stellar system known. Sirius B is faint because of its tiny size. Its diameter is only 7,500 miles (about 12 thousand kilometres), slightly smaller than the size of our Earth. The Sirius system is so close to Earth that most of the familiar constellations would have nearly the same appearance as in our own sky. In this rendition, we see in the background the three bright stars that make up the Summer Triangle: Altair, Deneb, and Vega. Altair is the white dot above Sirius A; Deneb is the dot to the upper right; and Vega lies below Sirius B. But there is one unfamiliar addition to the constellations: our own Sun is the second-magnitude star, shown as a small dot just below and to the right of Sirius A.

[1] Globular Star Cluster 47 Tuc Image Credit & Copyright: Dieter Willasch (Astro-Cabinet) Explanation: Globular star cluster 47 Tucanae is a jewel of the southern sky. Also known as NGC 104, it roams the halo of our Milky Way Galaxy along with some 200 other globular star clusters. The second brightest globular cluster (after Omega Centauri) as seen from planet Earth, it lies about 13,000 light-years away and can be spotted naked-eye near the Small Magellanic Cloud in the constellation of the Toucan. The dense cluster is made up of several million stars in a volume only about 120 light-years across. Red giant stars on the outskirts of the cluster are easy to pick out as yellowish stars in this sharp telescopic portrait. Globular cluster 47 Tuc is also home to exotic x-ray binary star systems.

[1] Designation NGC 3115, Bennett 42, Caldwell 53, the Spindle Galaxy Object type Type S(0) lenticular galaxy Coordinates 10 h 05 min - 07° 43' Sextans (Sex) Description NGC 3115 is also known as the ''Spindle Galaxy.'' It is a lenticular, a ''spiral galaxy without spiral structure'', i.e. a smooth disk galaxy, where stellar formation has stopped because the interstellar matter was used up. From their appearance and stellar contents, they can often hardly be distinguished from ellipticals observationally. Dreyer calls this lenticular galaxy very bright (mag 9.7), large (8.3'x3.2'), very much elongated (P.A. 46°), and brightening sharply to a brightened, elongated nucleus. It lies 4.8° north of Lambda Hydrae. North is to the right in the 15 x 10 arcmin field of view.

These stars formed together and are gravitationally bound. Stars orbit the center of the cluster, and the cluster orbits the center of our Galaxy. So far, about 140 globular clusters are known to exist in a roughly spherical halo around the Galactic center. Globular clusters do not appear spherically distributed as viewed from the Earth, and this fact was a key point in the determination that our Sun is not at the center of our Galaxy. Globular clusters are very old. There is a straightforward method of determining their age, and this nearly matches the 13.7 billion-year age of our entire universe.

[1] Elliptical Galaxy Centaurus A from CFHT Credit & Copyright: Jean-Charles Cuillandre (CFHT) & Giovanni Anselmi (Coelum Astronomia), Hawaiian Starlight Explanation: Why is peculiar galaxy Centaurus A so dusty? Dramatic dust lanes that run across the galaxy's center mark Cen A. These dust lanes are so thick they almost completely obscure the galaxy's center in visible light. This is particularly unusual as Cen A's red stars and round shape are characteristic of a giant elliptical galaxy, a galaxy type usually low in dark dust. Cen A, also known as NGC 5128, is also unusual compared to an average elliptical galaxy because it contains a higher proportion of young blue stars and is a very strong source of radio emission. Evidence indicates that Cen A is likely the result of the collision of two normal galaxies. During the collision, many young stars were formed, but details of the creation of Cen A's unusual dust belts are still being researched. Cen A lies only 13 million light years away, making it the closest active galaxy. Cen A, pictured above, spans 60,000 light years and can be seen with binoculars toward the constellation of Centaurus.

In the Center of the Virgo Cluster Credit & Copyright: Jean-Charles Cuillandre (CFHT), Hawaiian Starlight, CFHT Explanation: The Virgo Cluster of Galaxies is the closest cluster of galaxies to our Milky Way Galaxy. The Virgo Cluster is so close that it spans more than 5 degrees on the sky - about 10 times the angle made by a full Moon. It contains over 100 galaxies of many types - including spiral, elliptical, and irregular galaxies. The Virgo Cluster is so massive that it is noticeably pulling our Galaxy toward it. The cluster contains not only galaxies filled with stars but also gas so hot it glows in X-rays. Motions of galaxies in and around clusters indicate that they contain more dark matter than any visible matter we can see. Pictured above, the center of the Virgo cluster might appear to some as a human face, and includes bright Messier galaxies M86 at the top, M84 on the far right, NGC 4388 at the bottom, and NGC 4387 in the middle.
