Mandatory arrest in domestic violence call-outs causes early death in victims Posted: 02 Mar 2014 04:54 PM PST Researchers followed up on a landmark domestic violence arrest experiment and found that African-American victims who had partners arrested rather than warned were twice as likely to die young.

Talking Neanderthals challenge the origins of speech Posted: 02 Mar 2014 03:52 PM PST We humans like to think of ourselves as unique for many reasons, not least of which being our ability to communicate with words. But ground-breaking research shows that our 'misunderstood cousins,' the Neanderthals, may well have spoken in languages not dissimilar to the ones we use today.

Study of antibody evolution charts course toward HIV vaccine Posted: 02 Mar 2014 11:36 AM PST In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2. Many researchers believe that if a vaccine could elicit potent antibodies to a specific conserved site in the V1V2 region, one of a handful of sites that remains constant on the fast-mutating virus, then the vaccine could protect people from HIV infection.

First glimpse of brain circuit that helps experience to shape perception Posted: 02 Mar 2014 11:36 AM PST How do our memories shape the way sensory information is collected? For the first time, scientists have demonstrated a way to observe how our experiences shape sensory information in awake animals. The team was able to measure the activity of a group of inhibitory neurons that links the odor-sensing area of the brain with brain areas responsible for thought and cognition. This connection provides feedback so that memories and experiences can alter the way smells are interpreted.

Protective mutations for type 2 diabetes pinpointed Posted: 02 Mar 2014 11:36 AM PST Mutations in a gene that can reduce the risk of developing type 2 diabetes, even in people who have risk factors such as obesity and old age, has been found by an international team of researchers. The results focus the search for developing novel therapeutic strategies for type 2 diabetes; if a drug can be developed that mimics the protective effect of these mutations, it could open up new ways of preventing this devastating disease. Type 2 diabetes affects over 300 million people worldwide and is rising rapidly in prevalence. Lifestyle changes and existing medicines slow the progression of the disease, but many patients are inadequately served by current treatments.

In first moments of infection, a division and a decision Posted: 02 Mar 2014 11:35 AM PST Using technologies and computational modeling that trace the destiny of single cells, researchers describe for the first time the earliest stages of fate determination among white blood cells called T lymphocytes, providing new insights that may help drug developers create more effective, longer-lasting vaccines against microbial pathogens or cancer.

As one food allergy resolves, another may develop: Same food may trigger both allergies Posted: 02 Mar 2014 11:35 AM PST Some children who outgrow one type of food allergy may then develop another type of allergy, more severe and more persistent, to the same food. The more severe allergy is eosinophilic esophagitis (EoE), which has been increasing in recent years.

Brain research tracks internet safety performance, dispels assumptions, identifies traits of those at-risk Posted: 28 Feb 2014 09:11 AM PST Researchers used a novel methodology to gain new neurological insights into how users face security questions and how their personalities might affect their performance.
