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.

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.

Children's exposure to alcohol advertising during early adolescence appears to influence both beer drinking and their intentions to drink a year later, according to a RAND Corporation study issued today.

The study of children in the sixth and seventh grades found that those exposed to alcohol advertising at high levels – from television, magazines, in-store displays and promotional items like T-shirts and posters – were 50 percent more likely to drink and 36 percent more likely to intend to drink than children whose exposure to alcohol advertising was very low.

When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells. Researchers from the European Molecular Biology Laboratory (EMBL) have now worked out the mechanism underlying asymmetric cell division in nematode worms. The study, which is published in the current issue of Cell, reveals that interactions between the mitotic spindle and the cell cortex are crucial for asymmetric division.

After every meal, the body must prevent the immune system from launching an all-out fight against food. Now, researchers report the identity of a nutrient "floodgate" that serves to protect against such an inflammatory immune response.

The researchers found that animals lacking a protein enriched in fat cells, called STAMP2, develop acute inflammation in deep pockets of visceral fat. The animals also showed symptoms of metabolic syndrome—including insulin resistance and fatty liver disease—even while eating a regular diet.

IBM today announced the first-ever application of a breakthrough self-assembling nanotechnology to conventional chip manufacturing, borrowing a process from nature to build the next generation computer chips.

The natural pattern-creating process that forms seashells, snowflakes, and enamel on teeth has been harnessed by IBM to form trillions of holes to create insulating vacuums around the miles of nano-scale wires packed next to each other inside each computer chip.
