Scientists unravel the mystery of marine methane oxidation

Posted: 12 Nov 2012 05:56 AM PST

Microbiologists and geochemists from the Max Planck Institute for Marine Microbiology, along with their colleagues from Vienna and Mainz, show that marine methane oxidation coupled to sulfate respiration can be performed by a single microorganism, a member of the ancient kingdom of the Archaea, and does not need to be carried out in collaboration with a bacterium, as previously thought. They published their discovery as an article in the renowned scientific journal Nature.

Scientists Uncover a New Pathway that Regulates Information Processing in the Brain

Scientists at The Scripps Research Institute (TSRI) have identified a new pathway that appears to play a major role in information processing in the brain. Their research also offers insight into how imbalances in this pathway could contribute to cognitive abnormalities in humans.

The study, published in the November 9, 2012 issue of the journal Cell, focuses on the actions of a protein called HDAC4. The researchers found that HDAC4 is critically involved in regulating genes essential for communication between neurons.

Early stress may sensitize girls' brains for later anxiety
