Using antioxidants to combat radiation poisoning

This week, researchers from The University of Pittsburgh have found that a chemical similar to that found in red wine can protect against radiation sickness. Specifically, they looked at gamma (γ) radiation and how its effects might be reduced by a substance similar to resveratrol. Resveratro...

The Brain's First Whiff of Nicotine

A new study sheds more light on how the brain responds to its first ever whiff of nicotine. By looking at activity in the brain tissue of a rat as it’s exposed to nicotine for the very first time, Professor Daniel McGehee, at the University of Chicago, can help to understand how exposure to an addi...
