Brain’s immune system can play role in weight gain
Weight isn’t just calories in, calories out. When mice eat a fatty diet, immune cells in their brains become inflamed. That makes the animals gain more weight.

Many U.S. football players had brain disease, data show
The brains of more than 200 former football players were donated to science upon their deaths. Signs of severe brain trauma showed up in the vast majority.

Mild brain injury can cause bead-like swellings in brain cells
Mild head bumps cause temporary swellings — like beads in a necklace — within brain cells. If cells get enough time to heal, those “beads” will disappear.

Night lights have a dark side
Artificial light at night not only affects our view of the night sky, but also has the ability to impair animal behaviors — and probably our health.

Adolescents are brain-dense — and that’s good
Gray matter is densely packed in adolescents, brain researchers now find. This may explain how developing adults cope with decreasing gray matter volume.

Tongues ‘taste’ water by sensing sour
Water doesn’t taste like much, but our tongues need to detect it somehow. They may do it by sensing acid, a new study shows.
