While there already are materials that change color in response to UV exposure, those color-changes involve reorganization of the material's molecular structure, so it can only be used a few times. A new material known as SensoGlow, however, can be used to detect and measure UVs over and over.

An international team of astronomers has completed the most comprehensive ultraviolet survey of the local universe to date, with the help of the Hubble Space Telescope. The survey could help scientists better understand how stars come to form, and how galaxies like our own evolve over time.

Researchers have developed a new “mat” that can adsorb and destroy pollutants from water. It's made up of titanium dioxide nanoparticles embedded into polymer fibers, which destroys contaminants through UV light. The team says the design is faster, safer and more energy efficient than other systems.

For decades, it's been known that broad-spectrum UVC light kills viruses and bacteria. Unfortunately, it also causes skin cancer and cataracts in people. Now, however, scientists have discovered that a narrow spectrum of UVC can eradicate airborne viruses without harming humans.

Vitiligo destroys skin pigment, leaving areas of skin looking like they've been bleached white. Although steroid creams may help in some cases, often there isn't much that can be done. Help may be on the way, however, as doctors have had success using a combination of an arthritis drug and UV light.

UV Sense, L'Oréal's new ultraviolet light sensor, fits on the user's thumbnail. To get a reading from the device, you have to pass your smartphone over it. What if you want things to be even simpler, though? Well, you might want to try the no-phone-required LogicInk UV.

A team of researchers at the University of Alberta in Canada has uncovered an extraordinary new, previously undiscovered, fat-burning mechanism. The new study reveals fat cells just under the skin are sensitive to a specific spectrum of sunlight and shrink when exposed.

We've already seen bracelets that monitor the wearer's exposure to the sun's ultraviolet rays. Now, L’Oréal has teamed up with Northwestern University to create a thumbnail-mounted gadget that does the same job. According to the university, it is the world's smallest wearable device.

White-nose syndrome is a disease that infects bats as they hibernate, and it's been reducing their numbers in recent years. There may be new hope, however, as scientists have discovered that the fungus behind the disease is killed by exposure to UV light.

A new NASA study has poured another bucket of cold water on hopes of one day discovering life on the closest exoplanet ever discovered – the Earth-sized world Proxima b, which is thought to orbit in the habitable zone of the red dwarf Proxima Centauri.
