Scientists identify culprit in obesity-associated high blood pressure
Jan. 31, 2013 Researchers have described a key mechanism responsible for the brain’s regulation of obesity-associated disease. Obesity and its related conditions such as type 2 diabetes, cardiovascular disease and stroke are among the most challenging of today’s healthcare concerns
Linchpin of skin response to UVA light discovered
Jan. 21, 2013 Researchers have strengthened their understanding of how skin cells called melanocytes sense ultraviolet light and act to protect themselves with melanin. In a new study, they report experiments showing that an ion channel well-known elsewhere in the body for its chemical sensitivity, plays a central role in this process
DNA chip to diagnose attention deficit hyperactivity disorder?
Jan. 21, 2013 Attention Deficit Hyperactivity Disorder (ADHD) is the most common childhood neuropsychiatric disorder. Yet there is currently no tool that will confirm the diagnosis of ADHD
Surgical technique spots cancer invasion with fluorescence
Jan. 10, 2013 One of the greatest challenges faced by cancer surgeons is to know exactly which tissue to remove, or not, while the patient is under anesthesia. A team of surgeons and scientists at University of California, San Diego School of Medicine have developed a new technique that will allow surgeons to identify during surgery which lymph nodes are cancerous so that healthy tissue can be saved
New target for common heart condition identified
Jan. 8, 2013 Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation (AF), a common heart condition that causes an irregular and often abnormally fast heart rate.

‘Junk DNA’ made visible before the final cut
Jan. 7, 2013 Research findings from the University of North Carolina School of Medicine are shining a light on an important regulatory role performed by the so-called dark matter, or “junk DNA,” within each of our genes
Mimicking a natural defense against malaria to develop new treatments
Dec. 27, 2012 One of the world’s most devastating diseases is malaria, responsible for at least a million deaths annually, despite global efforts to combat it. Researchers from the Perelman School of Medicine at the University of Pennsylvania, working with collaborators from Drexel University, The Children’s Hospital of Philadelphia, and Johns Hopkins University, have identified a protein in human blood platelets that points to a powerful new weapon against the disease
New class of malaria drugs using essential calcium enzyme developed
Dec. 27, 2012 Calpain, a calcium-regulated enzyme, is essential to a host of cellular processes, but can cause severe problems in its overactivated state. It has been implicated as a factor in muscular dystrophy, AIDS, Alzheimer’s disease, multiple sclerosis, and cancer
