Newborn brains grow vision and movement regions first
The regions of the brain that control vision and other sensory information grow dramatically in the first few months following birth, while the area that controls abstract thought experiences very little growth during the same period, University of North Carolina at Chapel Hill researchers have found.
Decision-making -- Demonstration of a link between cognition and execution
For the first time, a team of researchers in the Movement, Adaptation, Cognition Laboratory (CNRS/University Victor Ségalen, Bordeaux) has revealed the existence of an interaction at the cellular level between cognitive information and motor information. This discovery provides the missing link between studies on decision-making processes and those relative to the execution of motor acts. It constitutes a fundamental advance in our understanding of the physiological role of the basal ganglia and, more specifically, of Parkinson's disease. This work was published on January 31 in The Journal of Neuroscience. more
Africa's first large-scale HIV vaccine study launches

The trial will involve up to 3,000 participants at five sites throughout South Africa and is expected to continue for four years. more
Standard therapy more effective than diabetes drug in helping women with PCOS achieve pregnancy
Metformin, a drug used to treat diabetes and once thought to have great promise in overcoming the infertility associated with polycystic ovary syndrome (PCOS), is less effective than the standard fertility drug treatment, clomiphene, according to researchers from the University of Pennsylvania School of Medicine and the National Institutes of Health Reproductive Medicine research network. This is the largest, most comprehensive effort yet to compare the two drugs in helping PCOS patients achieve successful pregnancy. The findings appear in the February 8th, 2007 issue of the New England Journal of Medicine. more
New study discovers how Pycnogenol lowers blood glucose levels in type 2 diabetes
A new study to be published in an upcoming edition of the journal of Diabetes Research and Clinical Practice reveals that French maritime pine tree extract known as Pycnogenol® (pic-noj-en-all) delays the uptake of glucose from a meal 190 times more than prescription medications, preventing the typical high-glucose peak in the blood stream after a meal.
Horse genome assembled
The first draft of the horse genome sequence has been deposited in public databases and is freely available for use by biomedical and veterinary researchers around the globe, leaders of the international Horse Genome Sequencing Project announced today. more
