Stealthy leprosy pathogen evades critical vitamin D-dependent immune response

Posted: 29 Jan 2012 12:11 PM PST

Researchers discovered that the leprosy pathogen Mycobacterium leprae was able to evade immune activity that is dependent on vitamin D, a natural hormone that plays an essential role in the body's fight against infections. A better understanding of how these pathogens can escape the immune system may be helpful in designing more effective therapies.

Do baby-faced opponents have a better chance of gaining your trust? By subtly altering fictional politicians' faces, researchers examined whether minor changes in appearance can affect people's judgment about "enemy" politicians and their offer to make peace. In the context of the Israeli-Palestinian conflict, the research showed that peace offers from baby-faced politicians had a better chance of winning over the opposing population than the exact same offer coming from more mature-looking leaders.

Genetic regulation of metabolomic biomarkers: Paths to cardiovascular diseases and type 2 diabetes

Posted: 29 Jan 2012 12:10 PM PST

Scientists have revealed eleven new genetic regions associated with the blood levels of the metabolites, including new loci affecting well-established risk markers for cardiovascular disease and potential biomarkers for type 2 diabetes. The findings may help in elucidating the processes leading to common diseases.
