The FDA has given marketing authorization to Zyn nicotine pouches. That doesn't necessarily mean they're safe to use, especially for young people, and experts say there's little evidence that they help adults quit smoking.

Scientists have found an elusive third form of magnetism that could help solve a longstanding puzzle about superconductors.

A new study suggests that the explosive deaths of the universe's earliest stars created surprising quantities of water that may have sparked extraterrestrial life in the very first galaxies.

A historic winter snowstorm has reached the Gulf Coast, smothering the region in Arctic air and dropping record-breaking amounts of snow on northern Florida.

A rare breed of star recently discovered by the Hubble Space Telescope spins faster by feeding on its stellar siblings.

Boom Supersonic's XB-1 demonstrator craft could become the first commercial jet to break the sound barrier since Concorde after acing its 11th test and reaching 0.95 Mach at low altitudes.

A man was diagnosed with skeletal fluorosis, which likely emerged due to him inhaling substances that damaged his bones.

"As yet, nobody has managed to understand what gives rise to this strange phenomenon, and explaining dark energy remains one of the most formidable challenges of modern science."

A nuclear fusion reactor in China, dubbed the "artificial sun," has broken its own record to bring humanity one step closer to near-limitless clean energy.

New photos of comet C/2024 G3 (ATLAS) suggest that it could be disintegrating due to "thermal stress" from its recent slingshot around the sun. However, its fate is still unclear.

A Roman-era cemetery, found ahead of a construction project in England, holds an unusual burial at its center.

Data collected by NASA's InSight lander suggest that ancient internal processes are responsible for the "Martian dichotomy" that splits the Red Planet into two distinct halves.

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.

Researchers unveiled a super-strong nanoscale material made from the first two-dimensional mechanically interlocked polymers. The material resembles medieval chainmail at the molecular level and could be used in body armor.

The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with more than 200 million individually resolved stars.

The world's fastest supercomputer 'El Capitan' can reach a peak performance of 2.746 exaFLOPS, making it the planet's third exascale computer.

Newly described scorpion can spray and inject its venom — the first South American species known to do this.

Quiz How's your knowledge of Earth's geology? Flat, round or global?

Earth from space A stunning composite image, made up of three years' worth of satellite photos, shows the ancient lava of Libya's Haruj volcanic field interspersed with patches of golden sand.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.
