    Platypus genome is as weird as its looks 18:00 07 May 2008 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...

    White Americans are both genetically weaker and less diverse than their black compatriots, a Cornell University-led study finds. Researchers analyzed the genetic makeup of 20 Americans of European ancestry and 15 African-Americans. The Europeans showed much less variation among 10,000 tested genes than did the Africans, which was expected, but also that Europeans had many more possibly harmful mutations than did African, which was not.

    DR. FEERO is a family physician with a doctorate in human genetics from the University of Pittsburgh. He is a senior adviser for genomic medicine in the Office of the Director at the National Human Genome Research Institute. Our understanding of the genome is changing rapidly and drastically. For starters, the Human Genome Project has revealed that humans are, on a numerical basis, genetically less complex than a mustard plant (Arabidopsis). In fact, our genome contains between 20,000 and 25,000 sequences suggestive of “genes” encoding proteins, whereas Arabidopsis contains about 27,000. If that doesn't make much sense to you, don't...

    Environment can change the way our genes work Environmental factors such as stress and diet could be affecting the genes of future generations leading to increased rates of obesity, heart disease and diabetes.A study of people suffering post-traumatic stress disorder (PTSD) after the 9/11 attacks in New York made a striking discovery. The patients included mothers who were pregnant on 9/11 and found altered levels of the stress hormone cortisol in the blood of their babies. This effect was most pronounced for mothers who were in the third trimester of pregnancy suggesting events in the womb might be responsible....

    Human Genome Has Four Times More Imprinted Genes Than Previously IdentifiedIn classic genetics, children inherit two copies of a gene, one from each parent, and both actively shape how the child develops. But in imprinting, one of those copies is turned off by molecular instructions coming from either the mother or the father. (Credit: Jane Ades, NHGRI) ScienceDaily (Nov. 30, 2007) — Scientists at Duke University have created the first map of imprinted genes throughout the human genome, and they say a modern-day Rosetta stone -- a form of artificial intelligence called machine learning -- was the key to their...

But where this technology will eventually lead to is of great concern to both the Danish Council of Ethics and the Council for Animal Ethics, who Tuesday presented their proposals for dealing with the unnerving prospect of combining human...

    The successful efforts of the Human Genome Project rightfully stand amongst the greatest intellectual achievements of human history. The brilliance and diligence displayed in this research cannot be quantified or described in a way that does it all justice. However, the question now becomes what we actually do with the knowledge of the human genome? Given the previous history of human technology, the heroic industry and intelligence of the scientists who achieved this discovery will in no way guarantee that it won’t fall into the hands of evil despots or malicious haters. It becomes possible that human beings as we...

    “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...

    PARIS (AFP) - Scientists in France and Italy have deciphered the complete genetic code for the plant producing wine grapes, according to a study published Sunday. While the findings will do nothing to enhance the mystique of winemaking, they could pave the way for gene-based manipulations to boost flavour and improve resistance against disease. Dozens of researchers analyzing the Pinot Noir varietal of Vitis vinifera, the core species from which virtually all grape wine is made, found twice as many genes contributing to aroma than in other sequenced plants, suggesting that wine flavours could be traced to the genome level....

    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...

    Researchers studying Neanderthal DNA say it should be possible to construct a complete genome of the ancient hominid despite the degradation of the DNA over time. There is also hope for reconstructing the genome of the mammoth and cave bear, according to a research team led by Svante Paabo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. Their findings are published in this week's online edition of Proceedings of the National Academy of Sciences. Debate has raged for years about whether there is any relationship between Neanderthals and modern humans. Some researchers believe that Neanderthals were simply...

    The researchers hope to scale the work up to the whole of the genome A close-up view of the human genome has revealed its innermost workings to be far more complex than first thought.The study, which was carried out on just 1% of our DNA code, challenges the view that genes are the main players in driving our biochemistry. Instead, it suggests genes, so called junk DNA and other elements, together weave an intricate control network. The work, published in the journals Nature and Genome Research, is to be scaled up to the rest of the genome. Views transformed...

    An international research consortium today published a set of papers that promise to reshape our understanding of how the human genome functions. The findings challenge the traditional view of our genetic blueprint as a tidy collection of independent genes, pointing instead to a complex network in which genes, along with regulatory elements and other types of DNA sequences that do not code for proteins, interact in overlapping ways not yet fully understood.
