Mathematicians show how shallow water may help explain tsunami power Posted: 18 Sep 2012 03:57 PM PDT While wave watching is a favorite pastime of beach-goers, few notice what is happening in the shallowest water. A closer look by two applied mathematicians has led to the discovery of interacting X- and Y-shaped ocean waves that may help explain why some tsunamis are able to wreak so much havoc.

Prejudice can cause depression at the societal, interpersonal, and intrapersonal levels Posted: 18 Sep 2012 03:56 PM PDT Although depression and prejudice traditionally fall into different areas of study and treatment, a new article suggests that many cases of depression may be caused by prejudice from the self or from another person. In a new article, experts argue that prejudice and depression are fundamentally connected.

Music underlies language acquisition, theorists propose Posted: 18 Sep 2012 03:56 PM PDT Contrary to the prevailing theories that music and language are cognitively separate or that music is a byproduct of language, theorists advocate that music underlies the ability to acquire language.

Statins are unlikely to prevent blood clots, large analysis finds Posted: 18 Sep 2012 03:56 PM PDT Despite previous studies suggesting the contrary, statins (cholesterol-lowering drugs) may not prevent blood clots (venous thrombo-embolism) in adults, according to a large analysis.

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.

Is magnetic therapy effective for tinnitus? Posted: 18 Sep 2012 03:47 PM PDT Loyola University Medical Center is studying whether a new form of non-invasive magnetic therapy can help people who suffer debilitating tinnitus (ringing in the ears).

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.
