Taking science to the track
An athlete took on science research with a few friends and a heart monitor.

Insects can patch their broken ‘bones’
When insects suffer wounds, they can mend their ‘skeleton’ with a patch on the inside. This makes the leg strong again, new data show.

Some air pollutants seep through skin
The skin is the body’s largest organ. And it can let in as much or more of certain air pollutants than enter through the lungs, a new study finds.

New light on brain science
A combination of physics, biology and engineering lets scientists use light to trigger actions by specific brain cells. Called optogenetics, this technology is shining new light on how the brain works.

These bubbles treat wounds
New research shows bubble-powered drugs can travel upstream, against the flow of blood, to seal wounds shut.

Hummingbird tongues may be tiny pumps
Scientists had thought that hummingbird tongues work through capillary action. A new study, though, concludes they work like little pumps.

Explainer: The nico-teen brain
Both e-cigarettes and tobacco products can release large amounts of nicotine during use. Nicotine is the chemical that makes tobacco addictive — and the teen brain is especially vulnerable to it.
