In adult monkeys, an antidepressant treatment has induced new nerve cell growth in the hippocampus, a brain area responsible for learning and memory. A similar process may occur in humans, the research suggests, and may help explain the effectiveness of antidepressant treatments.

Euthanasia for newborn babies with lethal and disabling conditions is illegal worldwide, but in reality, its acceptance and practice vary between different countries.

In the Netherlands, about 200,000 live births occur annually; of these, 10-20 babies – mostly with severe congenital malformations – are thought to be actively killed. Yet between 1997 and 2004 only 22 such deaths were reported to the authorities, writes Kate Costeloe, Professor of Paediatrics at the University of London.

COROT has provided its first image of a giant planet orbiting another star and the first bit of ‘seismic’ information on a far away, Sun-like star- with unexpected accuracy.

The unanticipated level of accuracy of this raw data shows that COROT will be able to see rocky planets - perhaps even as small as Earth - and possibly provide an indication of their chemical composition.

This is an artist’s impression of a Jupiter-sized planet passing in front of its parent star.
Such events are called transits. When the planet transits the star, the star’s apparent brightness drops by a few percent for a short period.

Astronaut Walter M. "Wally" Schirra Jr., one of the original Mercury Seven astronauts and the only man to fly on all three of NASA's early space missions, has died at the age of 84, a NASA official confirmed Thursday.

Schirra, who commanded the first rendezvous of two spacecraft in orbit, died of natural causes, according to NASA.

"We have spoken with his family and we can confirm he did die of natural causes.

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.

A new museum in Petersburg, Kentucky greets visitors with a 20ft tall tumbling waterfall and at its base, mannequins of frolicking children play amongst dinosaurs. The Creation Museum, which cost $25 million to build, is home to many unusual sites: a diorama of ancient people overshadowed by a towering T. rex, Adam and Eve swimming in a river with giant reptiles, and even a scale model of Noah's Ark.

It seems Noah solved the problem of fitting dinosaurs into his vessel by only taking baby dinosaurs. Indeed, the ark has a detailed display of many animals happily boarding the boat: dinosaurs cavort with giraffes, penguins, hippos, and bears.

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.
