Coral bleaching occurs when corals are stressed by high water temperatures and other factors, causing them to expel the symbiotic algae living within them. Given that fact, scientists are now looking into saving reefs by pumping up cool water from the ocean's depths.

Researchers at the Mayo Clinic have developed a test, called the Gut Microbiome Health Index, that can predict a person’s general health status by measuring the levels of 50 gut microbial species.

One method of 3D printing involves selectively exposing liquid resin to ultraviolet (UV) light, causing that resin to harden into a solid. Now, scientists have developed a new resin that works with safer, more energy-efficient visible light.

Some vaccines aren't very effective, which is due at least partially to the amount of time that they're active within the body. A new injectable hydrogel, however, could allow them to act for a longer period of time, making them more potent.

The Shyn Sonic Rechargeable Electric Toothbrush — complete with assorted brush heads, charger, and travel case — takes at-home oral care to a whole new level. Usually priced at $120, you can sport a healthier smile for only $52.99 — that's 55% off.

Sony has finally answered the last lingering questions about the PlayStation 5. After playing coy for months, the company has now revealed the next-generation console’s price, release date, plus a few new games and subscription service features.

NASA has discovered a strange star system where a gas giant planet is tightly orbiting a tiny white dwarf. This the first sighting of such an arrangement, raising questions about how the planet survived the star’s expansive death in the first place.

One of the largest, most complete and most famous Tyrannosaurus rex skeletons is about to go under the hammer. The dinosaur, nicknamed “Stan,” has been on display in the Black Hills Institute for decades, but will now be auctioned off by Christie’s.

Ultra wide-angle fisheye lenses are typically thick, bulbous contraptions, that can't easily be incorporated into devices such as smartphones. That could be about to change, though, as engineers have now created one that's completely flat.

Data captured by the Cassini spacecraft has been used to create a new infrared map of Saturn's moon Enceladus. The images highlight the icy world's dramatic "Tiger Stripe" vent formation, which leads to a subsurface ocean that could play host to life.

The German Aerospace Center has revealed a working prototype of a multi-use urban mobility and logistics vehicle called U-Shift, which is made up of an electric U-shaped base platform that's used to ferry around various pod modules.

While folding electric scooters are now a common sight, most of them still have fully rigid frames that bang over obstacles on the road. The Splach e-scooter is different, though, in that it incorporates front and rear coil-sprung suspension.
