| 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.  |
| That which does not kill yeast makes it stronger Posted: 29 Jan 2012 12:11 PM PST Stress-induced genomic instability facilitates rapid cellular adaption in yeast.  |
| Body clock receptor linked to diabetes in new genetic study Posted: 29 Jan 2012 12:10 PM PST Scientists have found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes.  |
| Cancer sequencing initiative discovers mutations tied to aggressive childhood brain tumors Posted: 29 Jan 2012 12:10 PM PST A cancer sequencing initiative has discovered mutations tied to aggressive childhood brain tumors. Early evidence suggests the alterations play a unique role in other aggressive pediatric brain tumors as well.  |
| 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.  |
| Astronomers solve mystery of vanishing electrons in Earth's outer radiation belt Posted: 29 Jan 2012 12:09 PM PST Researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt using data collected from a fleet of orbiting spacecraft.  |
| Tracking the birth of evolutionary arms race between HIV-like viruses and primate genomes Posted: 26 Jan 2012 09:30 AM PST Using a combination of evolutionary biology and virology, scientists have traced the birth of the ability of some HIV-related viruses to defeat a newly discovered cellular-defense system in primates.  |
