Surprising New Role for Calcium in Sensing Pain

September 2, 2014 1:54 pm | Videos | Comments

When you accidentally touch a hot oven, you rapidly pull your hand away. Although scientists know the basic neural circuits involved in sensing and responding to such painful stimuli, they are still sorting out the molecular players. Now, researchers have made a surprising discovery about the role of a key molecule involved in pain.

Training Your Brain to Prefer Healthy Foods

September 2, 2014 1:42 pm | News | Comments

It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods. A brain scan study in adult men and women suggests that it is possible to reverse the addictive power of unhealthy food while also increasing preference for healthy foods.
