Science News: Recent scientific discoveries and expert analysis

When does daylight saving time begin in 2026? Here's a look at when the time changes this year, and why we change our clocks in the first place.

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a black hole.

A 12th-century sword spotted jutting out of the seabed in Israel was designed for one-handed combat during the Crusades.

With potential safety improvements and lower manufacturing costs, Na-ion batteries are coming of age at precisely the right time

The experimental manufacturing process could one day deliver a vehicle with a 1,000-plus mile range, researchers say.

Some civilizations in inland China underwent dramatic changes and population drops 3,000 years ago. Now, researchers are using oracle bones, archaeological evidence and climate modeling to find out why.

An academic dives into the physics of multiple dimensions and whether it's possible to tie a knot in 4D.

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward Earth from 8 billion light-years away and was spotted thanks to a weird space-time trick first predicted by Einstein.

Detached orca fins scored with distinctive tooth marks suggest that killer whale cannibalism is happening — and it might explain some complex orca societies.

NASA's Artemis II is on track to shoot for the moon in April after engineers fixed the helium issue that grounded the mission's rocket last month.

Researchers have revealed that North American birds are declining at an accelerating rate in three regional hotspots associated with intense agriculture.

The portable computing powerhouse is capable of running 120-billion-parameter LLMs, roughly three times larger than GPT-3, without needing to access the internet or the cloud.

Antarctica is covered by a miles-thick ice sheet, but was that always the case? And when was the coldest continent ice-free?

Scientists have described Tanyka amnicola, a newly identified species of prehistoric creature that lived 275 million years ago and had a bizarre twisted jaw with sideways-facing teeth.

A new study suggests that "little red dots" spied by the James Webb Space Telescope could be the universe's short-lived first generation of gigantic stars, challenging an existing theory.

A study of 125 skeletons from two Neolithic cemeteries in Hungary has revealed that men and women had clear gender roles — but sometimes those roles were fluid.

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

A gold coin featuring the son of Charlemagne may have been a keepsake from a Viking invader who fought in the Great Heathen Army.

Here are the first images of the March 3 'blood moon' total lunar eclipse visible over North America, Australia, and eastern Asia.

A rare Japanese ant is the only species known to lack female workers and males; all of its young develop into parasitic queens that try to take over other colonies.
