Compound found in purple corn may aid in developing future treatments for type 2 diabetes, kidney disease Posted: 18 Sep 2012 03:47 PM PDT Diabetic nephropathy is one of the most serious complications related to diabetes, often leading to end-stage kidney disease. Purple corn grown in Peru and Chile is a relative of blue corn, which is readily available in the U.S. The maize is rich in anthocyanins (also known as flavonoids), which are reported to have anti-diabetic properties. Scientists investigated the cellular and molecular activity of purple corn anthocyanins (PCA) to determine whether and how it affects the development of diabetic nephropathy (DN). Their findings suggest that PCA inhibits multiple pathways involved in the development of DN, which may help in developing therapies aimed at type 2 diabetes and kidney disease.

Erroneous link between prostate cancer and retrovirus from mice confirmed: Contamination of XMRV in cancer tissue sample Posted: 18 Sep 2012 03:47 PM PDT A once-promising discovery linking prostate cancer to an obscure retrovirus derived from mice was the result of an inadvertent laboratory contamination, a forensic analysis of tissue samples and lab experiments -- some dating back nearly a decade -- has confirmed.

Rating HPV biomarkers in head, neck cancers Posted: 18 Sep 2012 11:56 AM PDT A new study of head and neck cancers finds that combinations of biomarkers are better than DNA alone in determining whether the human papillomavirus is involved. That's important because people with HPV-caused cancers are likely to fare much better than people whose cancer came from causes like smoking. Reliably assessing HPV's presence could prevent overtreatment.

Like a spring in a toy car: Catalysis mechanism of cell growth protein Ras clarified Posted: 18 Sep 2012 11:50 AM PDT Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists. Using a combination of infrared spectroscopy and computer simulations, they showed that Ras puts a phosphate chain under tension to such an extent that a phosphate group can very easily detach -- the brake for cell growth. Mutated Ras is involved in tumor formation, because this reaction slows down and the brake for cell growth fails.

Dictionary completed on language used everyday in ancient Egypt Posted: 18 Sep 2012 11:50 AM PDT A dictionary of thousands of words chronicling the everyday lives of people in ancient Egypt -- including what taxes they paid, what they expected in a marriage and how much work they had to do for the government -- has been completed by scholars at the University of Chicago.

Surprising demographic shifts in endangered monkey population challenge conservation expectations Posted: 18 Sep 2012 11:50 AM PDT At first glance, the northern muriqui monkey is a prime conservation success story. These Brazilian primates are critically endangered, but in the past 30 years a population on a private reserve has grown from just 60 individuals to some 300, now comprising almost a third of the total remaining animals. A recent analysis of the factors contributing to this population's tremendous growth reveals surprising trends that raise new questions about conservation, recovery and what constitutes a healthy population.

Sea surface temperatures reach record highs on Northeast continental shelf Posted: 18 Sep 2012 09:15 AM PDT During the first six months of 2012, sea surface temperatures in the Northeast Shelf Large Marine Ecosystem were the highest ever recorded. The annual 2012 spring plankton bloom was intense, started earlier and lasted longer than average. This has implications for marine life from the smallest creatures to the largest marine mammals like whales. Atlantic cod continued to shift northeastward from its historic distribution center.

Lack of sleep affects bone health and bone marrow activity Posted: 18 Sep 2012 09:15 AM PDT Scientists specializing in neurology, cell biology, neurobiology and anatomy have discovered abnormalities in bone and bone marrow in rats undergoing chronic lack of sleep. They discovered abnormalities in serum markers of bone metabolism in sleep-deprived rats, which led them to conduct direct measurements of bone parameters; this time in rats experiencing recurrent sleep restriction during a large portion of their young adulthood.

Oral bacteria may signal pancreatic cancer risk Posted: 18 Sep 2012 09:15 AM PDT Pancreatic cancer is highly lethal and difficult to detect early. In a new study, researchers report that people who had high levels of antibodies for an infectious oral bacterium turned out to have double the risk for developing the cancer. High antibody levels for harmless oral bacteria, meanwhile, predicted a reduced pancreatic cancer risk.

Protection for humans on Mars Posted: 18 Sep 2012 09:15 AM PDT For six weeks NASA's Mars rover Curiosity has been working on the Red Planet. NASA also plans to send humans to Mars within the next 20 years.

Women speak less when they're outnumbered Posted: 18 Sep 2012 09:12 AM PDT Scholars examined whether women speak less than men when a group collaborates to solve a problem. In most groups that they studied, the time that women spoke was significantly less than their proportional representation – amounting to less than 75 percent of the time that men spoke. The disparity vanished when groups followed a unanimous voting rule.

How much product information do consumers want? Posted: 18 Sep 2012 08:34 AM PDT In a new study, psychologists at Brown University and the University of Colorado found that while some people require a detailed explanation of how a product works before they'll be willing to pay more, others became less willing to pay when confronted with that additional detail. A simple, standard test predicted the desire for detail — who wants more, who wants less.

Quasars: Mileposts marking the universe's expansion Posted: 18 Sep 2012 08:34 AM PDT Researchers have found a possible way to map the spread and structure of the universe, guided by the light of quasars.

Researchers have now identified 21 proteins that specifically bind to the protein ataxin-1. Twelve of these proteins enhance the misfolding of ataxin-1 and thus promote the formation of harmful protein aggregate structures.

Obesity is major contributor to heart disease, impediment to diagnosis and treatment Posted: 18 Sep 2012 08:28 AM PDT Obesity is a major contributor to heart disease that substantially hinders the disease's proper diagnosis and treatment, says a cardiologist researching the impact of obesity and weight loss on the heart. With obese youth as the fastest-growing demographic group, the country's problem is only going to get worse, a preventive cardiologist says.

Longer exercise provides added benefit to children's health Posted: 18 Sep 2012 08:28 AM PDT Twenty minutes of daily, vigorous physical activity over just three months can reduce a child's risk of diabetes as well as his total body fat -- including dangerous, deep abdominal fat -- but 40 minutes works even better, researchers report.

Body fat location may determine type 2 diabetes risk for obese patients Posted: 18 Sep 2012 08:28 AM PDT Obese individuals with excess visceral fat (abdominal fat that surrounds the body's internal organs) have an increased risk for the development of Type 2 diabetes, according to a new study by researchers at UT Southwestern Medical Center.
