UV light

Researchers turn to high resolution sequencing to explain recurrent melanoma mutations caused by UV exposure.

Mice with low vitamin D had exaggerated craving for opioids and felt the drugs’ effects more strongly—results supported in part by human medical records—suggesting that supplements should be explored as treatments for opioid use disorders.

Researchers develop a caspase inhibitor that only works after being irradiated with UV light, giving them control over apoptosis in human cells.

Water bears can survive extreme temperatures, oxidative stress, UV radiation, and more, but as work in climate change biology shows, they’re not invulnerable to everything.

A new inhibitor gives researchers the ability to control programmed cell death in cultured human T cells.

Under UV light, flying squirrels give off a rosy glow.

A university investigation has so far found no wrongdoing by the principal investigator.

A new nanoparticle-based sunblock is effective, long-lasting, and may eliminate absorption of potentially harmful chemicals into the skin and bloodstream, a mouse study shows.

Researchers uncover a previously unknown way UV light can act on melanin, spurring cancer-causing mutations hours after sun exposure.

Chronic exposure to ultraviolet light leads to endorphin release and signs of addiction in mice.

UV light-emitting power lines may spook reindeer and other animals, a study finds.
