A new study suggests a severe decline in the number of young America pikas in the Rocky Mountains as the climate warms.

MIT researchers find large language models sometimes mistakenly link grammatical sequences to specific topics, then rely on these learned patterns when answering queries. This can cause LLMs to fail on new tasks and could be exploited by adversarial agents to…

Paleontologists have analyzed an exceptionally long sauropod trackway at the West Gold Hill Dinosaur Tracksite in Colorado, the United States. Their results show that the giant dinosaur which made it may have been limping.

Atoms found deep inside our planet argue that parts of “proto-Earth,” the early version of our planet, still survive inside the mantle.

Chinese start-up LandSpace is set to launch its first reusable rocket on Saturday. If it succeeds, it will give China’s space sector a major boost.

New gamma-ray evidence hints we may finally be “seeing” dark matter for the first time.

An undersea cable records 56,000 icebergs breaking off of glaciers in Greenland, revealing hidden signals that transform the ice melt.

The two stars in the nearby system ZTF J2130 are spiraling toward a catastrophic supernova. In the meantime, scientists are using the pair's slow orbital decay to put Einstein's theory of gravity to the test.

In a re-evaluation of Hockett's foundational features that have long dominated linguistic theory—concepts like "arbitrariness," "duality of patterning," and "displacement"—an international team of linguists and cognitive scientists shows that modern science d…

What: Falcon 9 rocket launch from Vandenberg Space Force in Santa Barbara County.  When: Between 10:18 a.m. and 11:25 a.m. Wednesday, according to SpaceX.

New research challenges long-held assumptions, revealing that Mars may have supported life for billions of years longer than previously believed.

NASA’s nearly complete Nancy Grace Roman Space Telescope has made another set of critical strides toward launch. This fall, the outer portion passed two tests

NASA's Perseverance rover spotted a possible space rock on the surface of Mars. The meteorite's nickname is 'Phippsaksla.'

The 2025 ozone hole is the fifth smallest since 1992, signaling significant progress in the recovery of Earth’s protective ozone layer thanks to international efforts like the Montreal Protocol.

The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they are measured, and the very act of measuring a quantum system changes everything. But according to new research published in Physical Re…

Technical advances allow researchers to trace the genetic changes that occur over time.

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants.

Stunning new photos show the pieces of the "other ATLAS," C/2025 K1, breaking apart in space after the golden comet suddenly exploded earlier this month.

High above a storm, a mysterious red ring appeared for a split second. Here's how one photographer captured the elusive "elve."

According to the team, the object likely came from the direction of Sagittarius, and will depart our Solar System towards Gemini. Before it leaves, it may have a course-altering encounter with our largest gas giant.

A rare Neanderthal fossil has just given scientists a peek into the past—and the findings inside its nose are more surprising than anyone expected.

Up to 30% of life, by weight, is underground. Seismic activity may renew the energy supply for subterranean ecosystems. Published in PNAS Nexus, Eric Boyd and colleagues chronicled the ecological changes in subsurface microbial communities that took place aft…

Superconductive materials can conduct electricity with no resistance, but typically only at very low temperatures. Realizing superconductivity at room temperature could enable advanced, energy-efficient electronics and other technologies.

The supercollider is now being used to explore quantum phenomena, including a “magic” form of quantum entanglement.
