Bite-size Science: Epigenetics help protect the aging brain

Epigenetics change which genes are active and which are inactive. Research over the past few years has shown that these changes are important for protecting the brain from neurodegeneration and injury. A review paper came out on May 18th in the journal Nature Reviews Neuroscience that summarizes this research. Check out the infographic for a description of the review paper.

Teleportation! Hippocampal Oscillations during Navigation

Who hasn’t wanted to snap their fingers and dive into the pages of the gorgeous places featured in National Geographic?  Caught in a miserable physics exam that you haven’t studied for?  No problem, with teleportation you can be whisked away to an expedition to Mars or an Australian beach.  Afraid of heights but curious about skydiving?  Immersion into an artificial, computer-simulated environment can emulate the look and feel of the real thing without any danger or risk.  Virtual reality enables the military to train pilots to fly planes without leaving the safety of the base.  Virtual environments are almost limitless in scope, allowing researchers to study complex motor behaviors.  These virtual environments are often experienced with a head mounted display that allows the participant to move freely within the perceived environment — be it a pre-historic landscape or a lunar landing.Continue reading
