As a group, young ADHD drivers are two to four times more likely to have a car accident than non-ADHD drivers. Daniel Cox, Ph.D., professor of psychiatry and neurosciences at the University of Virginia Health System, has conducted research aimed at improving those odds. His team's newest study will look at the effects of methylphenidate (MPH), a controlled-release stimulant, on young ADHD drivers facing real-life distractions.

Scientists at CNRS and the Pasteur Institute, collaborating with physicians in Gabon, have just undertaken a study on cerebral malaria in children living in an endemic region. This study, which was published in PLoS ONE, should allow us to better understand this severe form of malaria which affects 20 to 40 percent of people infected by the Plasmodium falciparum parasite, and is fatal in 30 to 50 percent of cases. The study also provides a lead on how to perfect a diagnostic test, which should allow for better patient care.

An oral vaccine can prevent mice from developing Prion disease. Prion diseases, which include scrapie, mad cow disease, and chronic wasting disease, are fatal and there is no treatment or cure.

The disease spreads when an animal eats the body parts of other animals contaminated with prions. The disease causes dementia and abnormal limb movements.

Plants scavenge nearly every photon of available light energy to produce food. Yet after many years of careful research into its exact mechanisms, some key questions remain about this fundamental biological process that supports all life on earth.

Children of women who took the epilepsy drug valproate during pregnancy appear to be at a greater risk for lower IQ, according to research presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28 – May 5, 2007.

The study looked at IQ results for 187 two-year-old children of mothers who took the epilepsy drugs carbamazepine, lamotrigine, phenytoin, or valproate during pregnancy.

Imagine taking a vitamin for longevity! Not yet, but a Dartmouth discovery that a cousin of niacin prolongs lifespan in yeast brings the tantalizing possibility a step closer.

The research, reported in the May 4 issue of Cell, shows how a new vitamin extends lifespan in yeast cells, much like calorie restriction does in animals. It could pave the way for developing supplements to benefit humans.
