Difference in talking louder, talking over noise depends on verbal cues, internal targets
...Surprising and differing results from three simple tasks
The researchers asked 15 men and 15 women in their early 20s to read short and long sentences at four "sound pressure levels" (SPL): comfortable, twice as loud as the comfortable level, 10 decibels (dB) higher than comfortable (with a visual clue fo...

involving that part of the brain. Schizophrenia patients typically perform poorly on such tasks. Earlier studies had shown that inheriting two copies of the more common val version leads to a slightly higher risk for schizophrenia and a signature pat...

such as carbon sequestration, phytoremediation, or the production of bio-fuels -- could also use functional imaging to help track their progress. In the New Phytologist study, the scientists asked how plants deal with an external stress, such as an i...
Tiny scaffolding allows stem cells to become working fat cells

Cooperation is keya new way of looking at MicroRNA and how it controls gene expression
... of gene expression is one of the most fundamental tasks
of every cell in the body because many of our genes encode proteins that may only be needed occasionally. Indeed, having some of these proteins around when they are not needed can create any number of problems for an organism, and failing to properly...
