    Platypus genome is as weird as its looks 18:00 07 May 2008 NewScientist.com news service Emma Young It's part-reptile, part-mammal, part-bird – and totally unique. Two centuries after European scientists deemed a dead specimen so outlandish it had to be a fake, the bizarre genetic secrets of Australia's platypus has been laid bare. Platypuses lay eggs and produce venom like some reptiles, but they sport furry coats and feed their young with milk like mammals. The odd creatures are classed as monotremes, with only one close relative – the echidna. But as primitive mammals that share the same ancestor as...

    Eight New Human Genome Projects Offer Large-scale Picture Of Genetic Difference ScienceDaily (May 2, 2008) — A nationwide consortium led by the University of Washington in Seattle has completed the first sequence-based map of structural variations in the human genome, giving scientists an overall picture of the large-scale differences in DNA between individuals. The project gives researchers a guide for further research into these structural differences, which are believed to play an important role in human health and disease. The results appear in the May 1 issue of the journal Nature. The project involved sequencing the genomes of eight people...

    Scientists find a fingerprint of evolution across the human genome The Human Genome Project revealed that only a small fraction of the 3 billion “letter” DNA code actually instructs cells to manufacture proteins, the workhorses of most life processes. This has raised the question of what the remaining part of the human genome does. How much of the rest performs other biological functions, and how much is merely residue of prior genetic events? Scientists from Cold Spring Harbor Laboratory (CSHL) and the University of Chicago now report that one of the steps in turning genetic information into proteins leaves genetic...

    “The gene is dead... long live the gene,” announced subtitles to an article in Science News this week.1 Geneticists have come to a striking conclusion over the last few years: genes are not the most important things in DNA, if they even exist as a concept. The “central dogma” of genetics, since Watson and Crick determined the structure of DNA, is that genetic information flows one-way – from the gene to the protein. In the textbooks, a gene was supposed to be a finite stretch of DNA that, when read by the translation process, produced a messenger RNA, which recruited...

    The study also found that these similarities were absent from fruit fly and nematode genomes, contradicting the widely held belief that organisms become more complex through evolution. The findings suggest that the ancestral animal genome was quite complex, and fly and worm genomes lost some of that intricacy as they evolved. It’s surprising to find such a “high level of genomic complexity in a supposedly primitive animal such as the sea anemone,” Koonin told The Scientist. It implies that the ancestral animal “was already extremely highly complex, at least in terms of its genomic organization and regulatory and signal transduction...

    Small but perfectly formed, Pelagibacter ubique is a lean machine stripped down to the bare essentials for life.Humans have around 30,000 genes that determine everything from our eye colour to our sex but Pelagibacter has just 1,354, US biologists report in the journal Science. What is more, Pelagibacter has none of the genetic clutter that most genomes have accumulated over time. There are no duplicate gene copies, no viral genes, and no junk DNA. 'Chicken soup'The spareness of its genome is related to its frugal lifestyle. The shorter the length of DNA that needs to be copied each generation, the...

    Opening a new front in the battle against cancer, federal officials are planning to compile a complete catalog of the genetic abnormalities that characterize it. The proposed Human Cancer Genome Project, as it is being called for now, would be greater in scale than the Human Genome Project, which mapped the human genetic blueprint. It would seek to determine the DNA sequence of thousands of tumor samples, looking for mutations that give rise to cancer or sustain it. Full Story

    1997PORTLAND, Oregon (CNN) -- Scientists have produced sibling rhesus monkeys from cloned embryos in the technology's closest application yet to a species related to humans. The monkeys were developed using cells from different embryos, so they are not genetically identical, said Don Wolf, senior scientist at the Oregon Regional Primate Research Center.

    Geographer of the Male Genome The notion of the Y sex chromosome as a genetic wasteland still entices biologists. David C. Page has spent a good part of his career knocking down that myth By Gary Stix DAVID C. PAGE: THE Y FILES Led what he calls an "anal-compulsive" effort to sequence the Y chromosome, a process akin to drawing a map of a hall of mirrors. The Y sequence shows that men and women differ as much in their genetic makeup as do, say, human and chimpanzee males. On the fascination with the "rotting Y": "It has to do...

    Black Death mutant gene resists Aids, say scientists Jan 4 2005 By Alan Weston, Daily Post IT HAS been described as the 'world's greatest serial killer'. The Black Death was a catastrophe which wiped out nearly half the European population, with 20m people dying between 1348 and 1350. But new research being carried out by a team from Liverpool University has shown that the disease may have produced an unexpected side-effect - resistance to the deadly HIV/Aids virus. Professor Christopher Duncan and Dr Susan Scott have already caused shockwaves among historians with their claim that the Black Death was caused...

    Controversial theorist Aubrey de Grey insists that we are within reach of an engineered cure for aging. Are you prepared to live forever? On this glorious spring day in Cambridge, England, the heraldic flags are flying from the stone towers, and I feel like I could be in the 17th century—or, as I pop into the Eagle Pub to meet University of Cambridge longevity theorist Aubrey de Grey, the 1950s. It was in this pub, after all, that James Watson and Francis Crick met regularly for lunch while they were divining the structure of DNA and where, in February 1953,...

    An e-friend breezed by the other day — a person, I mean, whom I had previously known only through his website and some e-mail exchanges on topics of common interest. He didn't stay long. I was at home with my son. My wife and daughter were out (shopping, ballet practice). My son was in his room playing a computer game. The guest impressed Danny tremendously by greeting him with: "Word!" Then, leaving the boy to his game, we went downstairs and chatted over a drink. The guest showed me some interesting websites. My wife came home and was introduced. I...
  • Human genome hits halfway mark

    Four years after publishing a draft of the human genetic sequence, researchers have hit the halfway mark in producing the "gold standard" version. They have just published a detailed run-down of a 12th chromosome - known as chromosome five - which means there are just 12 left to complete. [Snip] It is not just the genes in chromosome five that the scientists are interested in. Volumes of genetic material lie in between the genes, which for a long time were dismissed as "junk" by researchers. But on closer inspection, it seems this judgement was premature. The fact that sequences of...
  • Evolution's “Molecular Clock”: Not So Dependable After All?

    DNA mutates, and it's a good thing it does. If it didn't, there could only be one kind of life, not the millions there are today, and species could not adapt to new challenges. This is because mutations in genes—the coding portion of DNA—are the raw material for evolution. However, genes make up a surprisingly small fraction of our DNA. If the genome were a cookbook, its 30,000-odd genetic recipes would be scattered among millions of pages of apparently meaningless nonsense. Mutations affect all DNA, not just the genes, and this provides population geneticists with a veritable toolbox of methods...

    <p>Safeguarding your DNA is a huge 21st century privacy issue, says author George Annas. So why is the government sitting on its hands?</p> <p>In an election year, only vote-getting legislation seems to get Congress' attention. So I suppose it comes as no surprise that an important House bill, the Genetic Nondiscrimination in Health Insurance & Employment Act, has quietly been shunted -- once again -- to the bottom of the agenda. The bill, sponsored by Representative Louise Slaughter (D-N.Y.), would, as the name suggests, forbid employers from using genetic information to make hiring decisions or insurers from denying coverage or raising premiums.</p>

    NEW YORK - When noted biologist David Botstein was lured from Stanford University to head the Lewis-Sigler Institute for Integrative Genomics at Princeton, he had his choice of computing systems. But Botstein says he outfitted the center almost soup to nuts with Apple computers and servers, which are used for everything from desktop applications to comparing lengths of genetic code. By eschewing the more expensive workstations that high-tech biologists have come to rely on, he says he has also cut down on the cost of maintaining his number-crunching machines. Botstein's not alone. Apple Computer and its Macintosh, which has long...

    Scientists hail new 'map of life' By Dr David Whitehouse BBC News Online science editor A fruit fly and its protein interaction map Biologists have produced a detailed map of protein interactions in a complex organism - the fruit fly. Proteins, which are made by genes, are the building blocks of tissues as well as the basis for molecular interactions that enable an organism to live. The protein interaction map will allow a new insight into a highly complex metabolic system, similar in many ways to the human one. The research is to be published in a future issue of...

    Researchers have built the genome of a tiny virus from scratch in a feat they say will improve the speed and accuracy of constructing synthetic organisms. Led by genome sequencing pioneer J. Craig Venter, researchers from the Institute for Biological Energy Alternatives in Rockville, Maryland built the 5,386 base pair virus phiX174 using commercially available parts. IBEA researchers hope to use synthetic organisms for energy production and carbon sequestration, but their work also has potential for the production of health-related proteins and genes. Improved understanding "Work in creating a synthetic chromosome/genome will at its most basic level give us a...
