High school football players have changes in their brain function long before they have recognizable signs of a concussion, according to a new study.

Reporting in PLoS Biology, researchers write that they were able to correlate words a person was hearing to specific electrical activity in the brain. Study co-author neuroscientist Robert Knight discusses future applications of this research and concerns that it amounts to mental wiretapping.

As it circles Earth, NASA's Interstellar Boundary Explorer hunts for particles streaming in from beyond the solar system. It has intercepted hydrogen, helium, neon and oxygen atoms. IBEX principal investigator Dave McComas discusses how the abundance of those atoms hints at the Milky Way's composition.

In That's Disgusting: Unraveling the Mysteries of Repulsion, psychologist Rachel Herz discusses the origins of disgust — what she calls the 'instinct that's learned' — and why humans turn up their noses at smelly feet but devour expensive cheeses cultured with some of the very same stinky bacteria.
