Life from Scratch? :: Astrobiology Magazine :: Search for Life in the Universe "The goal is to fundamentally understand the components of the most basic living cell." According to the scientists' interview with the Washington Post : "We are wondering if we can come up with a molecular definition of life," Venter said. Despite such assertions, Knoll maintains that those who insist nanobes are alive have yet to prove their claims. www.astrobio.net /news/article319.html

TalkOrigins Archive - Feedback for February 2000 Also, there is an enormous gap between amino acids and a one celled organism. Why cant a 21 chromesome paired decay (still again i use that word) into a 22 celled organism? Plants have rigid cell walls, while animals have cell membranes which are more flexible, and plants include a cellular organelle (component) called a "chloroplast", itself the fusion of a eukaryote cell with another older form of cell known as a blue-green algae. www.talkorigins.org /origins/feedback/feb00.html

B020519A.Evidence5.htm As more and more work is done on how the DNA in every cell works in replication, this point becomes an even larger obstacle for the evolutionary explanation of all life forms being the result of mutations from a single-celled organism. When one considers the number of changes that would have to take place in order to change a single-celled organism into every life form in existence and the length of time necessary for each change, the problem becomes a mathematical one. Though one or two billion years is a great deal of time, various mathematical models have shown that even the time speculated would not provide enough time for the number of mutations which had to be made to result in the present life forms if we all started from a single-celled organism. www.reasonforhope.org /Bulletins/2002/B020519A.Evidence5.htm

Movement Of Single Molecules Imaged In Live Organism Over a period of a few seconds, the spots, which represent single molecules of cAMP bound to its receptor, move within the cell membrane before dropping off at random. "We can see single molecules binding to receptors and actually watch the receptors move," says Devreotes. Now, in the Oct. 26 issue of the journal Science, Japanese scientists and Devreotes describe success in imaging single molecules of cAMP as they interact with docking points, or receptors, on the surface of these amoebae. www.sciencedaily.com /releases/2001/10/011030072828.htm

Bacterium Researchers have abandoned this model, but the three-domain system has gained general acceptance. Some bacterial cells have capsules outside their cell walls, which are made up of polysaccharides, and form a covering or envelope around the cell. Bacterial flagella are arranged in many different ways. www.sciencedaily.com /encyclopedia/bacterium

Fungi: Straddling the Realms of Micro- and Macrobiology Hyphae are very tiny, measuring only a few microns in diameter in some cases. Many decades ago, scientists thought that fungi were primitive kinds of plants. A few fungal species have no cell dividers: just a long, continuous cell dotted by multiple nuclei spread throughout. www.microbeworld.org /htm/aboutmicro/microbes/types/fungi.htm

Article of the Month: 'The Sophisticated Ciliate" The process is rapid and amongst abundant food, like yeast cells which it appears to relish, it may engulf up to a hundred or more cells at one "sitting". The same goes for single celled animals, protozoa, like the ciliate Paramecium caudatum. Acid conditions maintain the dye as red or orange. www.imagequest3d.com /pages/articles/articleofmonth/ciliate

BBC News SCI/TECH Processing power of single cells The best known ciliate is called Paramecium, and all members of this order get their name from the tiny hairs, or cilia, that all these single-celled organisms use to get around and trap food. One large nucleus is used to keep the organism running on a day-to-day basis and is made up of separate strands of DNA, each one holding thousands of copies of the same gene. The technique is an economical way of searching and preserving the connections between lists of information. news.bbc.co.uk /hi/english/sci/tech/newsid_1535000/1535945.stm

Revolution With the one three-word phrase, ‘feeling of feeling,’ as he used it for his single term prehension, Whitehead inaugurated a new epoch in the intellectual history of mankind. To clarify your feel for the meaning of "prehension," a thought experiment may help, so imagine that you are back in your high-school science lab, and that you are observing the behavior of a very simple, single-celled organism, an amoeba, under a microscope. The objection is not solely that God would be made responsible for the imperfect adaptations and discords in nature. www.hyattcarter.com /revolution.htm

NIGMS -- News & Events: Tackling a 'Hairy Beast': NIGMS and NSF Fund Sequencing of Tetrahymena Genome Two new federal grants will allow scientists to sequence and analyze the genome of the single-celled model organism Tetrahymena thermophila in a collaborative effort that will benefit a wide range of research, from experimental cell and molecular biology to comparative and functional genomics. Tetrahymena is a member of a group of single-celled organisms called ciliates which are characterized by hairlike projections, or cilia, that allow them to swim. Major fundamental advances based on studies of Tetrahymena include determination of the structure and function of telomeres--the caps that protect the ends of chromosomes in eukaryotes--and the Nobel Prize-winning discovery that RNA can catalyze biochemical reactions. www.nigms.nih.gov /news/releases/tetrahymena.html

Yeast Underscores Complexity Of Genetic Variation Between People Finding multiple genetic regions implicated in any one disease or trait has been difficult because the human genome is so vast, containing some 30,000 genes through which to sift. But we have found that yeast also provides a great model for looking at genetic complexity in general," said Kruglyak, an associate member of Fred Hutchinson's Human Biology and Public Health Sciences divisions and a Howard Hughes Medical Institute investigator. This finding allows researchers for the first time to regard yeast as a viable model for understanding complex genetic traits and diseases in higher organisms, including humans. www.sciencedaily.com /releases/2002/04/020423080028.htm

Scientists Planning to Make New Form of Life (washingtonpost.com) Many of the 200 genes to be deleted will be ones that confer the ability to survive in a hostile environment, so that the end result will be a delicate creature, at home only in the warm nutrient bath of a laboratory dish. The more immediate plan is to try to puzzle out, and eventually model in a computer, every conceivable aspect of the biology of one organism, a feat science has never come close to accomplishing. People, by contrast, have an estimated 30,000 to 50,000 genes. www.washingtonpost.com /ac2/wp-dyn/A17496-2002Nov20?language=printer
