Common Oral Osteoporosis Drugs Linked To Serious Jaw Necrosis (January 2, 2009) -- Clinical data links oral bisphosphonates to increased jaw necrosis. The study is among the first to acknowledge that even short-term use of common oral osteoporosis drugs may leave the jaw vulnerable to devastating necrosis. Fosomax is the most widely prescribed oral bisphosphonate. ... > full story
Nothing To Sneeze At: Real-time Pollen Forecasts (January 2, 2009) -- Researchers in Germany are reporting an advance toward development of technology that could make life easier for millions of people allergic to plant pollen. It could underpin the first automated, real-time systems for identifying specific kinds of allergy-inducing plant pollen circulating in the air. ... > full story
Obesity Increases Lymphedema Risk For Breast Cancer Survivors (January 2, 2009) -- Throughout the world, 10 million breast cancer survivors have a lifetime risk for developing lymphedema, a chronic condition that involves swelling of the limbs and impacts physical and psychosocial health. In a new study, researchers found that the risk of developing lymphedema is 40 percent to 60 percent higher in women with body mass index classified as overweight or obese compared to normal weight women. The researchers recommend increased health education for breast cancer survivors. ... > full story
Structure Of New Botulism Nerve Toxin Subtype Revealed (January 2, 2009) -- Scientists have determined the structure of a third subtype of botulinum neurotoxin -- a deadly toxin that causes the disease botulism, and is also used in cosmetic and therapeutic applications. The structure reveals a unique arrangement of the active components that may help explain why subtype E is faster-acting than others -- and may have implications for improving vaccines and/or therapeutic agents. ... > full story
Toxicity Mechanism Identified For Parkinson's Disease (January 2, 2009) -- Alpha-synuclein is the main component of Lewy bodies, the clumps of aggregated proteins that form in the brains of Parkinson's disease patients. The alpha-synuclein gene is mutated or triplicated in some cases of inherited Parkinson's. A process called chaperone-mediated autophagy (CMA) plays an important role in recycling of specific proteins in brain cells. Alpha-synuclein disrupts a key survival circuit in brain cells by interfering with CMA and the recycling of the protein MEF2D. ... > full story
Weakened RNA Interference Reduces Survival In Ovarian Cancer (January 2, 2009) -- Levels of two proteins in a woman's ovarian cancer are strongly associated with her likelihood of survival, a research team reports ... > full story
Doctors Not Properly Diagnosing Overweight And Obesity In Children (January 2, 2009) -- Despite recent widespread media attention given to studies that have indicated one-third of American children have a weight problem, a new study shows just one-third of children who are overweight or obese actually receive that diagnosis by a pediatrician. The study also stresses that this failure to diagnose appears to mostly impact children who may most greatly benefit from early intervention. ... > full story

Religion May Have Evolved Because Of Its Ability To Help People Exercise Self-control (January 1, 2009) -- Psychologists reveal that religion facilitates the exercise of self-control and attainment of long-term goals. A psychology professor has found a strong correlation between religion and self-control, or self-regulation. He explains that religious people may have at their disposal a set of unique resources that makes them better suited to adhering to long term goals. ... > full story
How Chromosomes Meet In The Dark: Switch That Turns On X Chromosome Matchmaking (January 1, 2009) -- A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development. This is an important mechanism as the binding together of too many of too few of a particular chromosome can cause a number of medical conditions such as Down Syndrome. ... > full story
Grape-seed Extract Kills Laboratory Leukemia Cells, Proving Value Of Natural Compounds (January 1, 2009) -- An extract from grape seeds forces laboratory leukemia cells to commit cell suicide. Researchers found that within 24 hours, 76 percent of leukemia cells had died after being exposed to the extract. ... > full story
Evidence For Protective Effect Of Fish Oil Not Conclusive (January 1, 2009) -- Fish oil protects against deaths from heart problems, but doesn't provide a clear benefit in heart rhythm problems, according a new study. ... > full story
