    After nearly 30 years studying how plants use their genes to defend against viruses, Vicki Vance, a professor at the University of South Carolina, doesn’t see genetically modifying plants as a malevolent or arrogantly God-like endeavor. “There’s DNA in the world and it gets passed from one organism to another and it’s the natural thing. If that’s the problem you have with transgenic plants, that’s not a good reason to be against them,” Vance says. She does, however, have a problem with mega corporations allegedly using their money and power to hide the risks of new forms of genetic technology....

    A new bill to mandate labeling of genetically altered food gets history and science all wrong.Last week, in a victory for California’s radical anti-technology minority, S.B. 131 passed the state’s senate Health Committee by a vote of five to two. This misguided piece of legislation, introduced by state senator Noreen Evans, would require that “any food, except as provided, offered for retail sale in the state be considered misbranded if it is entirely or partially genetically engineered, as defined, and that fact is not disclosed in a specified manner.” In other words, it would require a label to inform consumers...

    Sometime in the future, technicians will go over the scene of the crime. They’ll uncover some DNA evidence and take it to the lab. And when the cops need to get a picture of the suspect, they won’t have to ask eyewitnesses to give descriptions to a sketch artist – they’ll just ask the technicians to get a mugshot from the DNA. That, at least, is the potential of new research being published today in PLOS Genetics. In that paper, a team of scientists describe how they were able to produce crude 3D models of faces extrapolated from a person’s...

    A MURDER has been committed, and all the cops have to go on is a trace of DNA left at the scene. It doesn't match any profile in databases of known criminals, and the trail goes cold. But what if the police could issue a wanted poster based on a realistic "photofit" likeness built from that DNA? Not if, but when, claim researchers who have developed a method for determining how our genes influence facial shape. One day, the technique may even allow us to gaze into the faces of extinct human-like species that interbred with our own ancestors. It's...

    Woolly mammoths are coming back, say cloning scientists In what sounds like it could be the plot for the next Jurassic Park movie, a team of scientists in Siberia says there's a 'high chance' that they will be able to clone a woolly mammoth. The breakthrough comes as a result of last year's discovery of an incredibly well-preserved mammoth carcass, frozen in the permafrost of Siberia's Malolyakhovskiy island. The scientists estimate that the animal is about 43,000 years old, and was 50-60 years old when it died in distress after getting stuck in the ice. In the ten months since...

    The roots of inheritance may extend beyond the genome, but the mechanisms remain a puzzle. When Brian Dias became a father last October, he was, like any new parent, mindful of the enormous responsibility that lay before him. From that moment on, every choice he made could affect his newborn son's physical and psychological development. But, unlike most new parents, Dias was also aware of the influence of his past experiences — not to mention those of his parents, his grandparents and beyond. Where one's ancestors lived, or how much they valued education, can clearly have effects that pass down...

    WASHINGTON (AP) - Federal health regulators will consider this week whether to green light a provocative new fertilization technique that could eventually create babies from the DNA of three people, with the goal of preventing mothers from passing on debilitating genetic diseases to their children. The Food and Drug Administration has framed its two-day meeting as a "scientific, technologic and clinical" discussion about how to test the approach in humans. But the technique itself raises a number of ethical questions, including whether the government should sanction the creation of genetically modified humans.

    "Because our approach uses only genetic data, it provides information independent from other sources. Many of our genetic observations match historical events, and we also see evidence of previously unrecorded genetic mixing. For example, the DNA of the Tu people in modern China suggests that in around 1200 C.E., Europeans similar to modern Greeks mixed with an otherwise Chinese-like population. Plausibly, the source of this European-like DNA might be merchants travelling the nearby Silk Road."

    This post has been elaborated here.1. Just because an argument is politically strategic, does not make it true: A couple of years ago, the Human Rights Campaign, arguably the country’s most powerful lesbian and gay organization, responded to politician Herman Cain’s assertion that being gay is a choice. They asked their members to “Tell Herman Cain to get with the times! Being gay is not a choice!” They reasoned that Cain’s remarks were “dangerous.” Why? “Because implying that homosexuality is a choice gives unwarranted credence to roundly disproven practices such as ‘conversion’ or ‘reparative’ therapy.

    Researchers say they’ve found more DNA evidence that possibly shows gay men don’t have a choice — that their biological makeup drives them to homosexuality. In a study at Chicago University, researchers looked at DNA chains of 400-plus pairs of gay brothers and found what they said were two distinct bits of genetic material that they claim are linked to homosexuality, The Daily Mail reported. The gay brothers were identified and recruited to help with the study over the course of several years’ worth of Gay Pride festivals and marches. The research was highlighted during the recent annual American Association...

Stoltzfus, who heads Monsanto's Piilani seed production farm on Maui, was referring to the white disposable coveralls that protesters wear for the TV cameras when "decontaminating" biotech crop fields. Hawaii is the epicenter of a furious campaign to shut down production farms that yield genetically modified seed. It was September,...

    Being gay could be in the DNA. Scientists have found two stretches of DNA linked to homosexuality in men. The confirmation of the existence of a ‘gay gene’ or genes will strengthen arguments that homosexuality is a matter of biology, rather than choice. However, it also raises the prospect of a genetic test that could be used by insurance companies to discriminate against clients or by pregnant women to abort gay babies. In the study, Chicago University researchers analysed the DNA of more than 400 pairs of gay brothers, recruited at Gay Pride festivals at marches over several years. This...

But a new genetic study is stirring the waters, suggesting comb jellies, gelatinous marine animals that look similar to jellyfish, are actually the first animals to have evolved over 600 million years ago.

    Scientists have discovered a second code hiding within DNA. This second code contains information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease. UW scientists were stunned to discover that genomes use the genetic code to write two separate languages. One describes how proteins are made, and the other instructs the cell on how genes are controlled. One language is written on top of the other, which is why the second language remained hidden for so long. The genetic code uses a 64-letter alphabet called codons. The UW team...

Most researchers agree that Paleoamericans moved across the Bering Land Bridge from Asia sometime before 15,000 years ago, suggesting roots in East Asia. But just where the source populations arose has long been a mystery. Now comes a surprising twist, from the complete nuclear genome of a Siberian boy who died 24,000 years ago—the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today's Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or...

    t is unlikely that a mammoth could be cloned in the way we created Dolly the sheep, as has been proposed following the discovery of mammoth bones in northern Siberia. However, the idea prompts us to consider the feasibility of other avenues. Even if the Dolly method is not possible, there are other ways in which it would be biologically interesting to work with viable mammoth cells if they can be found. In order for a Dolly-like clone to be born it is necessary to have females of a closely related species to provide unfertilised eggs, and, if cloned embryos...

    By differentiating between bacterial and viral fevers, a new test may help doctors decide whether to prescribe antibiotics. Fevers are a common symptom of many infectious diseases, but it can be difficult to tell whether viruses or bacteria are the cause. By measuring gene activity in the blood of 22 sick children, Gregory Storch, a pediatrician and infectious disease researcher at Washington University in St. Louis and colleagues were able to distinguish bacteria-sparked fevers from ones kindled by viruses. The activity of hundreds of genes changed as the children’s immune systems responded to the pathogens, but the team found that...

    Scientists say they have established a genetic link between three North American women, one who died 5,000 years ago, one 2,500 years ago and one living. The evidence shows the living woman, a Tsimshian from the Metlakatla First Nation in British Columbia, is descended from the women who died centuries ago or from one of their close female relatives, PostMedia News reported. All three had the same mitogenome or mitochondrial DNA, which is passed from mother to child. The research conducted by Canadian and U.S. scientists was published this week in PLoS ONE, one of the journals produced by the...

    In a study that could change the way scientists view the process of protein production in humans, University of Chicago researchers have found a single gene that encodes two separate proteins from the same sequence of messenger RNA. Published online July 3 in Cell, their finding elucidates a previously unknown mechanism in human gene expression and opens the door for new therapeutic strategies against a thus-far untreatable neurological disease. "This is the first example of a mechanism in a higher organism in which one gene creates two proteins from the same mRNA transcript, simultaneously," said Christopher Gomez, MD, PHD, professor...

Credit: Mark Knobil/Creative Commons Cholera kills thousands of people a year, but a new study suggests that the human body is fighting back. Researchers have found evidence that the genomes of people in Bangladesh—where the disease is prevalent—have developed ways to combat the disease, a dramatic case of human evolution happening in modern times. Cholera has hitchhiked around the globe, even entering Haiti with UN peacekeepers in 2010, but the disease's heartland is...

    Enlarge Image Burning fat in the cold. White fat cells sense cold directly, and release energy to warm up. Credit: Biophoto Associates/Science Source Transforming fat cells into calorie-burning machines may sound like the ultimate form of weight control, but the idea is not as far-fetched as it sounds. Unexpectedly, some fat cells directly sense dropping temperatures and release their energy as heat, according to a new study; that ability might be harnessed to treat obesity and diabetes, researchers suggest. Fat is known to help protect animals from the cold—and not only by acting as insulation. In the early 1990s,...

    This bit of science arcanum is especially cringe-worthy. Many years ago, scientists first discovered that a large minority of women have Y-chromosome gene sequences in their blood. At first glance, this seems strange. Men are born with Y-chromosomes but most women are not. The male cells in these women must’ve come from somewhere else. But where? The most obvious source is a fetus. Nearly every woman who has ever been pregnant or had a baby has cells from her fetus circulating in her bloodstream. These cells filter through the placenta and reside in the mother’s bloodstream and/or organs — including...

    An team of scientists and researchers from across the world have managed to reconstructed a dozen medieval and modern leprosy genomes. The results suggest a European origin for the North American leprosy strains found in armadillos and humans, and there is a common ancestor of all leprosy bacteria within the last 4000 years.Humans appear to be the ones who adapted to leprosy, causing its decline in Europe. Credit: EPFL A breakthrough in sequencing ancient bacteria It is the first time scientists have reconstructed an ancient genome without a reference sequence (de novo) due to the extraordinary preservation of the medieval...

    The Supreme Court unanimously ruled Thursday that human genes isolated from the body can’t be patented, a victory for doctors and patients who argued that such patents interfere with scientific research and the practice of medicine. The court was handing down one of its most significant rulings in the age of molecular medicine, deciding who may own the fundamental building blocks of life. The case involved Myriad Genetics Inc., which holds patents related to two genes, known as BRCA1 and BRCA2, that can indicate whether a woman has a heightened risk of developing breast cancer or ovarian cancer. Justice Clarence...

    Paris, France: Low levels of vitamin D can trigger hypertension, according to the world's largest study to examine the causal association between the two. Although observational studies have already shown this link, a large-scale genetic study was necessary before the cause and effect could be proven, the annual conference of the European Society of Human Genetics (ESHG) will hear today (Tuesday). Dr. Vimal Karani S, from the Institute of Child Health, University College London, London, UK, will tell the meeting that data from the D-CarDia collaboration, involving 35 studies, over 155,000 individuals, and numerous centres in Europe and North America,...
