Anxiety Significantly Reduced With Manipulation of a Single Brain Molecule

Rhesus monkeys at the University of California – Davis are showing promise to cure anxiety after scientists isolated and boosted a single brain molecule. Researchers Andrew Fox, of UC Davis, and Tade Souaiaia, of SUNY, lead a study to determine if manipulation of the amygdala could mitigate behaviors that relate to anxiety and depression. The amygdala is the portion of the brain that controls memories and the emotions associated with them.

Brain Implant Device Controlled by Smartphone App

Yes, there’s an app for that! Korean and American scientists have invented a device capable of controlling neural circuits and distributing light and drug therapies to defined areas of the brain that is completely manipulated by a smartphone app. Neuroscientists now have a tool to trigger any specific combination or sequence of light and drug delivery into an implanted target animal without being present in the laboratory.

New Hereditary Mutation Identified to Increase Pancreatic Cancer Risk

While studying a cancer-prone family, scientists have identified an inherited gene mutation that considerably enhances the risk of pancreatic and other cancers. The previously unknown mutation was defined in Nature Genetics by researchers at Dana-Farber/Brigham and Women’s Cancer Center. The discovery could lead to the routine testing of those with a family history of pancreatic cancers to uncover the mutation known as RABL3. If the mutation is identified, pancreatic cancers may be diagnosed earlier and in a stage that is much more treatable.
