The study uses fMRI to map brain activity in response to cocaine, revealing a broader range of brain structures involved than previously thought. The nucleus accumbens and amygdala play key roles in the reward system, with the former associated with reinforcement and the latter with incentive.
A new electronic device can detect even small holes in high-pressure gas pipelines, issuing an immediate warning if a pipeline or tank is struck by a hard object. The system relies on listening devices that analyze signal changes from within the vessel to identify leaks.
Scientists have discovered a crucial region on nerve cells that may be essential for the actions of inhaled anesthetics, potentially leading to safer, more potent pain medications. The finding also provides insight into the genetics of alcohol addiction and may help develop new treatments.
