Plants are continuously exposed to solar ultraviolet (UV) radiation, which, while potentially damaging, also functions as an essential environmental signal. The responses to UV radiation encompass a ...

Lichen from the Mojave Desert can survive, and replicate, under levels of extreme solar radiation found on Earth-like planets in other solar systems. The question of whether Earth is alone in ...

Lichen from the Mojave Desert has stunned scientists by surviving months of lethal UVC radiation, suggesting life could exist on distant planets orbiting volatile stars. The secret? A microscopic ...

Ultraviolet radiation, a high-frequency form of energy from the sun, is classified in the same risk category as X-rays and nuclear radiation. As temperatures and sun exposure increase, experts at the ...

A long-running Queensland study has found children today are developing significantly fewer moles than kids 25 years ago, with predictions of a major reduction in future melanoma risk. The Brisbane ...

Weather forecasts usually include a UV index, a measure of the intensity of ultraviolet radiation from the sun. The higher the number, the greater the risk to people. Most of the radiation that ...

For years, medical advice on sun exposure has remained largely consistent: limit direct sunlight, apply sunscreen liberally, and wear protective clothing to minimize the risk of skin cancer. But as ...

Airplane windows don’t fully block ultraviolet rays, so dermatologists recommend wearing sunscreen—especially in the window seat. At high altitudes, UV exposure is more than double what you would be ...

LED or Light-emitting diode bulbs are household things these days. These have become the dominant technology for lighting thanks to their energy efficiency and long life values. There’s no doubt that ...
