Take a pot of scalding water, remove all the oxygen, mix in a bit of poisonous carbon monoxide, and add a pinch of hydrogen gas. It sounds like a recipe for a witch's brew. It may be, but it is also the preferred environment for a microbe known as Carboxydothermus hydrogenoformans. more  

Mutations in HRAS gene sequence confirmed in patients with Costello syndrome

Gene mutations in the HRAS sequence are present in most patients affected with Costello syndrome, according to a new study in the American Journal of Medical Genetics. The mutations occurred de novo in patients, meaning, they were not observed in their parents' genes. The study is published in the December issue of the journal. more

Chemical used in food containers disrupts brain development  

The chemical bisphenol A (BPA), widely used in products such as food cans, milk container linings, water pipes and even dental sealants, has now been found to disrupt important effects of estrogen in the developing brain. more
