What goes in doesn’t go out?
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
Diatoms - like those seen under a microscope here - can teach us a lot about harvesting light.
Diatoms' tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
Don’t skimp on the SPF.

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.
A male Hypsiboas punctatus frog in daylight.
Scientists in Argentina have discovered a frog that glows in moonlight and at twilight.
A basic design of a light-based chip.
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.
A visualisation of simulation data showing light successfully trapped at a standstill.
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.
Nanophotonics uses photons to do amazing things.
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.
Every day stuff for supernovae.
In 1934, two physicists came up with a theory that described how to create matter from pure light. But they dismissed the…
No photon bunches, please.
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…
Scientist have managed to bind light together to form molecules, a state of matter which has been compared to creating a…
Teleportation is still well and truly entrenched in science fiction, unless you’re a photon.
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…
When you shine a torch into a dusty room, not all the photons reach their destination.
Simon Greig (xrrr)
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…
Cheap solar cells could attain a record-breaking 40 percent efficiency level following the development of a “turbo” technology…
