The heat index is expected to soar this weekend. Here's what to know about the scale, potential dangers and how to protect yourself from UV radiation.

UV radiation damages skin cells Sunburns are an immune system response, not a "mindset," as the post alleges. When ultraviolet light from the sun makes contact with skin, it can induce the ...

Such ultraviolet radiation also heats the surface of the planet-forming disk of gas and dust, and as the gases on the surface of the disk warm up, they expand and are subject to being dragged away ...

Radiation from nail dryers may damage DNA and cause permanent mutations in human cells, a study has found. Dermatologists weigh in on the risks and whether they avoid gel manicures.

A type of lichen was able to survive extreme UV radiation in the lab, suggesting that ozone protection might not be required for life on exoplanets.

Induction of apoptosis of keratinocytes by ultraviolet (UV) radiation is a protective phenomenon relevant in limiting the survival of cells with irreparable DNA damage. Changes in UV-induced ...

Americans are being urged against using eight ultraviolet wands used to disinfect surfaces because of high levels of radiation the products emit that can cause injuries to the skin and eyes of ...

Last summer the U.S. Food and Drug Administration issued a warning about eight brands of UV wands that it said give off unsafe levels of radiation.

Ultraviolet radiation from sunshine seems to thwart multiple sclerosis, but perhaps not the way most researchers had assumed, a new study in mice suggests. If validated in further research, the ...
