Two Components of Red Meat Combined With Alteration in DNA Repair Increase Risk for Bladder Cancer Posted: 18 Oct 2012 08:17 AM PDT Two components of red meat — dietary protein and dietary iron — may combine to form powerful carcinogens, N-nitroso compounds, which increase risk for bladder cancer. Moreover, individuals with reduced ability to reverse the effects of N-nitroso compounds because of a genetic variation in their RAD52 gene could be at particularly high risk. read more

A cancer diagnosis does not make young people religious Posted: 18 Oct 2012 08:13 AM PDT A sociologist of religion from the University of Copenhagen has interviewed 21 young patients diagnosed with a life-threatening cancer about their religious beliefs. She concludes that a cancer diagnosis will not make young people, who are not religious already, turn to religion. But it can confirm already existing beliefs. read more

Viruses act like self-packing suitcases Posted: 18 Oct 2012 07:57 AM PDT Researchers at the University of Leeds have identified a crucial stage in the lifecycle of simple viruses like polio and the common cold that could open a new front in the war on viral disease. The team are the first to observe at a single-molecule level how the genetic material (genome) that forms the core of a single-strand RNA virus particle packs itself into its outer shell of proteins. Lead researcher Professor Peter Stockley said their results overturn accepted thinking about the process and could open a chink in the armour of a wide range of viruses. read more

Evolution mostly driven by brawn, not brains Posted: 18 Oct 2012 07:31 AM PDT The most common measure of intelligence in animals, brain size relative to body size, may not be as dependent on evolutionary selection on the brain as previously thought, according to a new analysis by scientists. Brain size relative to body size has been used by generations of scientists to predict an animal’s intelligence. For example, although the human brain is not the largest in the animal kingdom in terms of volume or mass, it is exceptionally large considering our moderate body mass. read more

Pacific Islanders, South Asians and Filipinos Have Higher Rates of Diabetes Than All Other Ethnic Groups Posted: 17 Oct 2012 06:49 PM PDT Rates of diagnosed diabetes are much higher among some Asian subgroups than is apparent when aggregating all Asians as a whole, according to a new study by the Kaiser Permanente Division of Research and the University of California, San Francisco (UCSF) which appears in the current online issue of Diabetes Care. read more

Doctors who go digital provide higher quality healthcare Posted: 17 Oct 2012 06:44 PM PDT The use of electronic health records is linked to significantly higher quality care, according to a new study by Lisa Kern and her team, from the Health Information Technology Evaluation Collaborative in the US. Their work appears online in the Journal of General Internal Medicine², published by Springer. Electronic health records (EHRs) have become a priority in the US, with federal incentives for 'meaningful' use of EHRs. Meaningful use entails tracking and improving specific patient outcomes, as well as gathering and storing information. read more

Study Finds Potential New Drug Therapy for Crohn’s Disease Posted: 17 Oct 2012 03:49 PM PDT Ustekinumab, an antibody proven to treat the skin condition psoriasis, has now shown positive results in decreasing the debilitating effects of Crohn’s Disease, according to researchers at the University of California San Diego, School of Medicine.  The study will appear in the October 18, 2012 issue of the New England Journal of Medicine (NEJM). read more

PMS may not exist, research shows Posted: 17 Oct 2012 03:42 PM PDT There is no clear link between women’s negative moods and the pre-menstrual phase of their cycles, according to a review of research led by University of Toronto experts. The team analyzed 41 research studies that tracked women’s daily moods through their menstrual cycles. Their findings — which showed no clear evidence that pre-menstrual syndrome (PMS) exists — are published online now in the journal Gender Medicine and are drawing international attention in the news world and blogosphere. read more

New military apparel repels chemical and biological agents Posted: 17 Oct 2012 03:34 PM PDT Lawrence Livermore National Laboratory scientists and collaborators are developing a new military uniform material that repels chemical and biological agents using a novel carbon nanotube fabric. read more

Proof at last: Moon was created in giant smashup Posted: 17 Oct 2012 12:06 PM PDT It’s a big claim, but Washington University in St. Louis planetary scientist Frédéric Moynier says his group has discovered evidence that the Moon was born in a flaming blaze of glory when a body the size of Mars collided with the early Earth. read more

HIV may leave gut vulnerable to infections Posted: 17 Oct 2012 11:59 AM PDT An HIV-like virus in primates appears to leave the gastrointestinal tract vulnerable to infection with other potentially harmful viruses, according to new research at Washington University School of Medicine in St. Louis, Harvard Medical School and other institutions. read more

Keck observations bring weather of Uranus into sharp focus Posted: 17 Oct 2012 11:56 AM PDT In 1986, when Voyager swept past Uranus, the probe's portraits of the planet were "notoriously bland," disappointing scientists, yielding few new details of the planet and its atmosphere, and giving it a reputation as a bore of the solar system. Now, however, thanks to a new technique applied at the Keck Observatory, Uranus is coming into sharp focus through high-resolution infrared images, revealing in incredible detail the bizarre weather of the seventh planet from the sun. read more

Daily multivitamin reduces cancer risk, offering enormous medical potential Posted: 17 Oct 2012 11:48 AM PDT One of the largest, longest, placebo-controlled clinical trials ever done on the use of a daily multivitamin/mineral to prevent cancer in men has shown a remarkable 8 percent drop in overall cancers during a 13-year study period – findings that may have repercussions on health care around the world. read more

Cognitive training helps adults with HIV, Study finds Posted: 17 Oct 2012 11:03 AM PDT As more effective antiretroviral therapy has evolved over the past 30 years, HIV/AIDS has shifted from an acute to a chronic condition. But as patients live longer, research indicates that they are experiencing cognitive impairments at a higher rate than people without the disease. read more

Breech births cause more problems for moms and babies when water breaks early Posted: 17 Oct 2012 10:32 AM PDT Breech births increase the risk of complications for the mother and baby when the amniotic sac ruptures early.
