    • Evolutionary Theory Takes Big Leap With Evo-Devo

      New York Times  |  Jun 26, 07 9:39 AM CDT

      Evolutionary Theory Takes Big Leap With Evo-Devo

      (Newser) - Evolutionary theory is in the early days of its third great expansion, the New York Times reports, following Darwin’s original formulation almost 150 years ago and the so-called “modern synthesis” of 1930-50. Dubbed “evo-devo” because it focuses on the embryonic development of organisms, the newest science explores how specific genes control significant aspects of an organism’s growth. More »

    • Early Immunity to Chimp Virus Leaves Humans Open to HIV

      Scientific American  |  Jun 22, 07 10:36 AM CDT

      Early Immunity to Chimp Virus Leaves Humans Open to HIV

      (Newser) - Humans are more susceptible to HIV than other primates because our ancestors evolved a protein that could fight off a different retrovirus that infected chimps, says Scientific American . The most conspicuous difference between the chimpanzee genome sequenced in 2005 and the human one, says a Seattle virologist, was 130 copies of a retrovirus that inserted its DNA into cells, as HIV does today.

      Amazon Tribe Broods Over Poached Blood

      (Newser) - An Amazon tribe is bilious after scientists took blood samples in exchange for medicine they never got, the Times reports. Doctors collected DNA from the Karitiana Indians in the late '70s and again in 1996, and then sold it to researchers for $85 a pop. But now the once remote tribe has made contact with the Western world, and wants compensation. More »

    • Breast Cancer Can Come From Dad, Too

      Associated Press  |  Jun 20, 07 4:53 AM CDT

      Breast Cancer Can Come From Dad, Too

      (Newser) - Half of congenital breast cancer victims inherit the disease from their fathers, not their mothers, according to a new study. And unless dad has female relatives with the affliction, the responsible gene may go undiscovered. The study in JAMA warns doctors, increasingly screening family trees for cancer, not to overlook the paternal genetic danger of the devastating disease. More »

    • Dog Breeders Deploy DNA Tests

      New York Times  |  Jun 12, 07 8:11 AM CDT

      Dog Breeders Deploy DNA Tests

      (Newser) - With the first map of a dog genome recently completed, scientists are hot on the trail of  genes for individual canine traits from coat color to cocking their heads in a cutesy way—and dog breeders are right behind them. Without any of the inhibitions attached to eugenics in humans, they're snapping up genetic tests to improve their breeds. More »

    • Genes Give Up Secrets of 7 Serious Diseases

      BBC  |  Jun 7, 07 8:18 AM CDT

      Genes Give Up Secrets of 7 Serious Diseases

      (Newser) - In an outcome one scientist describes as a "new dawn," researchers have identified genetic variations linked to seven common diseases, opening the door to improved tests and treatments. The study, which focused on depression, Crohn's disease, coronary artery disease, hypertension, rheumatoid arthritis, and Type 1 and 2 diabetes, also found unexpected links between some of the ailments.

    • Chemicals in Tap Water, French Fries May Cause Breast Cancer

      Chemicals in Tap Water, French Fries May Cause Breast Cancer

      (Newser) - Hundreds of common chemicals—from a substance used in French fries to one found in tap water—may cause breast cancer, a new report linking the disease to everyday products suggests. Researchers say they've found a link between cancer in animals and more than 200 common chemicals, many of which the federal government doesn't regulate. More »

    • Researchers Link Gene, Heart Disease

      New York Times  |  May 4, 07 7:50 AM CDT

      Researchers Link Gene, Heart Disease

      (Newser) - A gene that can more than double the risk of heart disease, especially in relatively young people, is present in about half of those of European descent, researchers say. The discovery, reported this week, raises hopes of more accurate genetic testing for heart disease—the world's leading cause of death—but not for prevention or treatment. More »

      Twins Found to Be &quot;Semi-identical&quot;

      (Newser) - A new kind of twin has been discovered, neither strictly identical nor fraternal. Now toddlers, the babies look identical but one is anatomically male while the other has ambiguous genitalia. Genetic tests show the children are identical on their mother's side but share only half their father's DNA. More »

      NASA Shutters Ideas Factory

      (Newser) - In a cost-cutting move, NASA is shutting down its futuristic think tank, source of way-ahead-of-the-curve ideas, many of them worthy of a Star Trek script. Closing the Institute for Advanced Concepts will save $4 million out of NASA’s $16 billion dollar budget. But former NASA scientist Keith Cowing describes the decision as “just plan stupid.. explorers without the right tools die.” More »
