7:26 PM | Researchers find new clues in treating chronic pain
A chemical in the brain typically associated with cognition, movement and reward-motivation behavior — among others — may also play a role in promoting chronic pain, according to new research. The chemical, dopamine, sets the stage for many important brain functions, but the mechanisms that cause it to contribute to chronic pain are less well understood.

6:36 PM | Mind reading: Researchers observe moment a mind is changed
Researchers studying how the brain makes decisions have, for the first time, recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. The findings result from experiments led by electrical engineering Professor Krishna Shenoy, whose Stanford lab focuses on movement control and neural prostheses – such as […]

11:22 PM | Fracked, shale-drilling additives in drinking-water taps near leak
Shale oil has helped the US see lower gas prices and even an opportunity to start exporting. However, it isn’t as great as it might sound, hydraulic fracturing — also known as fracking — has been scrutinized by environmentalists since it’s inception. As it turns out, for good reason, substances commonly used for drilling or […]
