Active volcanoes were erupting on the far side of the moon 2.8 billion years ago, the first lunar samples returned from the far side reveal.

Current AI models struggle to solve research-level math problems.

While investigating a rare developmental disorder, researchers ended up discovering a spectrum of conditions that are all linked to one gene.

A low-pressure system headed for Northern California and Oregon is likely to bring extreme rain and strong winds.

The Lafayette meteorite was discovered in a drawer at Purdue University in 1931, with no clear indication of how it got there. A new analysis of the rock reveals evidence of liquid water on Mars 742 million years ago.

A teenager in Canada is critically ill with the country's first human case of H5N1 bird flu. Health officials aren't sure how the youth was exposed.

The clonal quaking aspen known as Pando is between 16,000 and 80,000 years old.

Hurricane Helene sent gravity waves rippling through the atmosphere far above the southeastern United States, new NASA images reveal.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

We now know the nerve responsible for dogs shaking water all over your dry clothes.

A scathing new report points to unclear protocols and multiple failures to raise alarms at the Arecibo Observatory in Puerto Rico before the collapse of the site's radio telescope in 2020.

An eruption of Indonesia's Lewotobi Laki-laki stratovolcano rained debris and ash on villages on the island of Flores.

Earth surface is covered with rigid plates that move, crash into each other and dive into the planet's interior. But when did this process begin?

On a young Earth, giant meteors might have been a harbinger of life, not death.

A father and daughter team based in the U.S. have decoded a mock "alien signal" beamed from ESA's ExoMars Trace Gas Orbiter a year ago — but the meaning of the extraterrestrial message remains a mystery.

The mantle is split up into two domains — the African and the Pacific — that emerged when supercontinent Pangaea broke apart.

Researchers think that microgravity could help grow liver "organoids" that could be used in medical research and even in transplant surgeries, someday.

Lava that erupts from hotspots around the world seems to come from a similar ancestral magma, new research finds.

An odd phenomenon called lithospheric dripping might occur wherever mountains form.

There's a theoretical limit to the maximum sustained wind speeds of hurricanes, but climate change may increase that "speed limit."

Scientists were able to treat a "macular hole" in a monkey, helping to restore the animal's vision thanks to human stem cells.

A newly discovered doughnut shape in Earth's outer core may reveal elements that help drive the formation of the planet's magnetic field.

The ancient coelacanth, which has existed for some 419 million years, never stopped evolving despite its reputation as a "living fossil." A new discovery reveals that it evolved faster when plate tectonics were most active.

Volcanoes spewing carbon dioxide 250 million years ago heated the climate so much that extreme El Niño events became the norm, pushing most life on Earth past its limits.
