    Nature News ^ | 15 February 2012 | Heidi Ledford
    Changes to metabolism disrupt cells' ability to differentiate. The mystery of how mutations in a gene called isocitrate dehydrogenase 1 (IDH1) cause brain cancer and leukaemia is beginning to be unravelled. Researchers have discovered that the mutations cause the production of an enzyme that can reconfigure on–off switches across the genome and stop cells from differentiating. The findings, published in three papers today in Nature1–3, could be used in the development of drugs for cancers with these mutations — a search that is already under way in many pharmaceutical companies. Some cancer patients could benefit from new treatments that target...

Credit: Jan Kranendonk/iStockphoto You might assume that if you're healthy, you have a normal, healthy genome. But there is no such thing as a normal genome—all of us carry a number of mutated and nonfunctioning genes. Now researchers have estimated exactly how many such genes there are in the average person: about 100, including 20 mutated and completely inactive genes. We probably don't need some of this DNA and in some cases could even be better off without it. Soon after researchers began to...

    The scattered islands of the vast Pacific Ocean were settled by seafarers who set out from the eastern coasts and islands of Asia and traveled thousands of kilometers by boat. Meanwhile pre-Columbian South America was populated by people who crossed a now-vanished land bridge far to the north. Did these two groups ever meet in the New World? There's a good chance of that, according to a new study, which finds evidence that Easter Islanders may have reached South America and mixed with the Native Americans already there. University of Oslo immunologist Erik Thorsby first began analyzing the people of...

    A person's intelligence is mostly inherited, it's in their genes, but whether a person can expect to be a clever grandma or grandpa relies on both genes and environment. "Until now, we have not had an estimate of how much genetic differences affect how people's intelligence changes across the lifetime," study researcher Ian Deary, of the University of Edinburgh in the United Kingdom, said in an email to LiveScience. "These new results mean that researchers can seek both environmental and genetic contributionsto successful cognitive aging." Previous studies of the genetics of intelligence have been performed on sets of twins or...

    Researchers scanning the genomes of African-Americans say they see evidence of natural selection as their ancestors adapted to the harsh conditions of their new environment in America. The scientists, led by Li Jin of the Chinese Academy of Sciences in Shanghai, report in the journal Genome Research that certain disease-causing variant genes became more common in African-Americans after their ancestors reached American shores — perhaps because they conferred greater, offsetting benefits. Other gene variants have become less common, the researchers say, like the gene for sickle cell hemoglobin, which in its more common single-dose form protects against malaria. The Shanghai...

    Studies track biochemical patterns from just after conception to old age Human brains all work pretty much the same and use roughly the same genes in the same way to build and maintain the infrastructure that makes people who they are, two new studies show. And by charting the brain’s genetic activity from before birth to old age, the studies reveal that the brain continually remodels itself in predictable ways throughout life. In addition to uncovering details of how the brain grows and ages, the results may help scientists better understand what goes awry in brain disorders such as schizophrenia...

"Given the genetic variation of people today, [Venema] says scientists can't get that [starting] population size below 10,000 people at any time in our evolutionary history," NPR reported.2 But this claim fails for three reasons.

    Genetic differences between people account for up to half of the variation in intelligence, according to a study of more than 3,000 individuals. Intelligence is known to run in families, but no single genes have yet been identified that can be reliably linked to mental ability. Instead, researchers think, many hundreds or thousands of genes could be involved, each with a small influence on a person's overall intelligence. "It has been getting clearer and clearer that any genetic contribution to traits on which people differ – like height and weight – comes about from large numbers of gene differences, each...

Mr. Holbrooke, 69, was a larger-than-life figure, a fearless and robust man who was apparently struck down without warning. He became ill on a Friday, and was dead by Monday. According to government officials, the cause was a tear in his aorta, the artery that carries blood from the heart to vessels that feed the rest of the body. Mr. Holbrooke underwent 21 hours of surgery from Friday to Saturday to repair the damage, and then another seven-hour operation on...

    The Insanity VirusSchizophrenia has long been blamed on bad genes or even bad parents. Wrong, says a growing group of psychiatrists. The real culprit, they claim, is a virus that lives entwined in every person's DNA. by Douglas Fox Steven and David Elmore were born identical twins, but their first days in this world could not have been more different. David came home from the hospital after a week. Steven, born four minutes later, stayed behind in the ICU. For a month he hovered near death in an incubator, wracked with fever from what doctors called a dangerous viral infection....

    There’s a feud brewing on the prairie between faith and farming. Another church has voted to leave the Evangelical Lutheran Church in America, but this time it’s over a new stance the denomination’s leadership plans to take. Congregation members at Anselm Trinity Lutheran Church in rural Sheldon, N.D., don’t like the ELCA’s proposed position on genetics — specifically in relation to farmers’ use of genetically modified seeds, which are common in Red River Valley agricultural production. The congregation voted Sunday to leave the ELCA because it feels the group’s draft social statement on genetics is an attack on farmers. The...

    Liberals may owe their political outlook partly to their genetic make-up, according to new research from the University of California, San Diego, and Harvard University. Ideology is affected not just by social factors, but also by a dopamine receptor gene called DRD4. The study's authors say this is the first research to identify a specific gene that predisposes people to certain political views. Appearing in the latest edition of The Journal of Politics published by Cambridge University Press, the research focused on 2,000 subjects from The National Longitudinal Study of Adolescent Health. By matching genetic information with maps of the...

    Researchers have determined that genetics could matter when it comes to some adults' political leanings. According to scientists at UC San Diego and Harvard University, "ideology is affected not just by social factors, but also by a dopamine receptor gene called DRD4." That and how many friends you had during high school. The study was led by UCSD's James Fowler and focused on 2,000 subjects from the National Longitudinal Study of Adolescent Health.

    In 2008, Time magazine named retail DNA testing the invention of the year. A scant two years later it is questionable whether this exciting new industry will survive heavy-handed regulation by the U.S. Food and Drug Administration (FDA). In June, the FDA sent letters [PDF] to the leading direct to consumer (DTC) genetic testing companies asserting the agency's authority to require "premarket review" of their tests in order to "protect the public from medical products that may pose an unreasonable risk of harm." So what are the "unreasonable risks" posed by the DTC tests?Unlike X-rays or pharmaceuticals, there are no...

  • Bayer admits GMO contamination out of control

    (NaturalNews) Drug and chemical giant Bayer AG has admitted that there is no way to stop the uncontrolled spread of its genetically modified crops. "Even the best practices can't guarantee perfection," said Mark Ferguson, the company's defense lawyer in a recent trial. Two Missouri farmers sued Bayer for contaminating their crop with modified genes from an experimental strain of rice engineered to be resistant to the company's Liberty-brand herbicide. The contamination occurred in 2006, during an open field test of the new rice, which was not approved for human consumption. According to the plaintiffs' lawyer, Don Downing, genetic material from...

    jenningsthecat writes "A study published in December 2009 in the International Journal of Biological Sciences found that three varieties of Monsanto genetically-modified corn caused damage to the liver, kidneys, and other organs of rats. One of the corn varieties was designed to tolerate broad-spectrum herbicides, (so-called 'Roundup-ready' corn), while the other two contain bacteria-derived proteins that have insecticide properties. The study made use of Monsanto's own raw data. Quoting from the study's 'Conclusions' section: 'Our analysis highlights that the kidneys and liver as particularly important on which to focus such research as there was a clear negative impact on the...

    Enlarge Image Buried gem. Researchers have uncovered "fossil virus" inside the zebra finch genome. Credit: Peripitus/Wikimedia The hepatitis B virus and its ilk have been around for a long, long time. A newly uncovered "viral fossil" buried deep in the genome of the zebra finch indicates that the hepatitis B family of viruses—known as hepadnaviruses—originated at least 19 million years ago. Together with recent findings on other viruses, the work suggests that all viruses may be much older than thought. No one knows exactly where or when viruses originated. They don't leave fossils, so scientists have begun scouring the...

    A pensioner who has smoked almost 300,000 cigarettes during his lifetime has celebrated his 100th birthday. Arthur Langran, who survived being blown up by a grenade during the Second World War, claims the secret behind his longevity is always doing what everyone tells him not to. The father-of-two started smoking when he was 20 and has smoked at least ten cigarettes every day since then - the equivalent of 292,000. The centenarian, from Bury St Edmunds in Suffolk, also drinks a glass of single malt whisky every night before he goes to bed, another factor he credits for his long...
