Although sunscreen does help protect our skin from the sun's harmful UV rays, it isn't designed to keep that skin cool. An experimental new sunscreen does that very thing, however, while maintaining an SPF rating of about 50.

No matter how important something is, too much of anything is bad for you. Scientists have now put that principle to work to kill cancer, with a new drug that causes calcium to build up and choke the tumor to death.

“Astronomers discover a completely unknown object floating around in space” is a common news theme, but it’s fun every time. The latest is a brand new type of star – ancient red giants the team has nicknamed “Old Smokers.”

It’s easy to forget that most animals don’t see the world the way humans do. In fact, many perceive colors that are invisible to us. But now, for the first time, scientists have found a way to capture footage as seen by animals, and it's mesmerizing.

Astronomers have discovered the most distant – and therefore earliest – known black hole. Hiding in a galaxy called GN-z11, this black hole is bigger than should be possible given the age of the universe.

The James Webb Space Telescope may have been touted a successor to Hubble, but the old-timer still has some life left in it. These two iconic instruments have now teamed up to take a deep-field image of the colorful “Christmas Tree galaxy cluster.”

The best places to search for life beyond Earth aren’t planets like Mars – they’re icy moons like Europa. The case for life on this watery world just got stronger, as the James Webb Space Telescope has detected a fresh carbon source there.

The James Webb Space Telescope has achieved one of the first major science goals announced for it way back in 2017. The infrared instrument has now probed the atmosphere around one of the TRAPPIST-1 exoplanets.

When Captain Kirk stepped out with a tricorder in hand in Star Trek in 1966, the data sensing, scanning and analyzing gadget seemed a rather useful but far-in-the-future piece of technology. With the Swift Ray 1, we're a step closer to its reality.

Astronomers have witnessed an apocalypse from across the galaxy, as a planet crashed into its star. It’s an event long assumed to happen in many star systems – including our own someday – but this is the first time it’s ever been seen directly.

Astronomers have detected a supermassive black hole ripping a passing star to shreds. Not only was this closer to Earth than ever seen before, but its location and light emissions were unusual, hinting at a large unseen population of these events.

Unlike the stuff underneath your TV cabinet, interstellar dust plays a major part in the total luminosity of the galaxy. Scientists have used long-term observational data to see how interstellar dust correlates with a star’s brightness.
