How do the chemicals in sunscreen protect our skin from damage?
Energy from the sun's rays can cause skin damage and cancers. Sunscreens can absorb or reflect the dangerous UV light. Here's how it works.
Academic rigor, journalistic flair

The world’s first glow-in-the-dark frog found in Argentina
Scientists in Argentina have discovered a frog that glows in moonlight and at twilight.
The future of electronics is light
As electronic transistors get tinier, they approach a point at which they won't be able to get smaller. How can we keep shrinking our devices, and making them more powerful at the same time? Light.
Hold it right there: how (and why) to stop light in its tracks
Freezing light in mid-air isn't just the realm of Star Wars, as new research shows. But what do you do with the light once it's trapped? One option is to use it to develop new forms of computers.
Small and bright: what nanophotonics means for you
Nanophotonics deals with photons at the nanometre scale, and it's set to transform everything from internet speeds to turning your smartphone into a portable science lab.
‘Supernova in a bottle’ will help create matter from light
In 1934, two physicists came up with a theory that described how to create matter from pure light. But they dismissed the…
The power of one: single photons illuminate quantum technology
Quantum mechanics, which aims to describe the nano-scale world around us, has already led to the development of many technologies ubiquitous in modern life, including broadband optical fibre communication…
Scientists create ‘light saber’ state of matter
Scientist have managed to bind light together to form molecules, a state of matter which has been compared to creating a…
Teleportation just got easier – but not for you, unfortunately
Thanks to two studies published in Nature last Thursday, the chance of successful teleportation has considerably increased. Which is a good thing, right? Whether or not you’ve ever been on a long-haul…
‘Louder’ light could power a brighter quantum future
All of the light we see around us comes in chunks of energy known as photons. As well as making up light, photons can be used to carry and process information and their quantum properties make possible…
New solar technique to turbo charge cells
Cheap solar cells could attain a record-breaking 40 percent efficiency level following the development of a “turbo” technology…
