Brains may need flexible networks to learn well
New data suggest that brain cells may learn best when they are able to easily make and break off communications with neighbors — or distant brain regions.
- Ecosystems
As trees come down, some hidden homes are disappearing
Animals such as frogs, toucans and possums live in tree hollows. But as people have cut down trees, a wildlife housing shortage has developed in some places.

Molecular scissors fix disease-causing flaw in human embryos
Researchers moved closer to being able to fix gene-edited embryos in people. They removed a flawed gene that causes heart failure

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.

Mindfulness in eating pays the body big dividends
Schools are starting to use mindful eating in the classroom — and science shows that it can reduce overeating and improve overall health.

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.

Could a dragonfly’s wings be alive — and breathing?
Highly magnified image showing what looks like breathing tubes suggests the morpho dragonfly’s wings may be unexpectedly alive.

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.
