Fossils

An oceanographer explains how climate change, warming oceans and a souped-up atmosphere are creating conditions for deadly floods.

When navigating home, Magellanic penguins alternate between heading straight back in calm waters and swimming with the flow in strong ocean currents.

Anxious dogs might react nervously to some television sounds, a survey of dog owners reports, while hyper ones might try to play chase.

Earth has survived huge temperature swings over eons of climate change. Humans might not be so lucky.

Snow leopard cubs have been photographed in Mongolia - the first time researchers have visited one of the animals' dens since 2019

The cells helps the snakes absorb the bones of their prey — and might show up in other animals that chomp their meals whole.

Serrations at the edges of a fossilized flipper of the ancient marine reptile Temnodontosaurussuggests it may have been able to swim silently.

A young sunlike star called HOPS 315 seems to host a swirling disk of gas giving rise to minerals that kick-start the planet formation process.

Defense lawyers have called shaken baby syndrome, or abusive head trauma, junk science. But doctors say shaking a baby is dangerous.

In human beings, egg cells need to survive for about five decades, much longer than most other cell types – and they may achieve this unusually long lifespan by slowing down their natural cell processes

The image offers the first evidence for a previously unconfirmed origin story of type 1a supernovas.

Blood tests could pave the way for distinguishing between Alzheimer’s, Parkinson’s and some dementias, aiding early treatment for brain diseases.

Blood proteins that reveal some organs age faster than others — and that may predict disease and lifespan.

Ambitious projects aim to put dire wolves, woolly mammoths and passenger pigeons back into our ecosystems. But with so many technical and ethical hurdles, what is the real motivation?

In Empire of AI, journalist Karen Hao investigates OpenAI and the social and environmental costs of a multinational tech arms race.

Tracks of dinosaur footprints can hint at how fast the extinct animals moved. Here’s how guinea fowl can help fact-check those assumptions.

Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

For centuries, we’ve imagined Neanderthals as distant cousins — a separate species that vanished long ago. But thanks to AI-powered genetic research, scientists have revealed a far more entangled history. Modern humans and Neanderthals didn’t just cross paths; they repeatedly interbred, shared genes, and even merged populations over nearly 250,000 years. These revelations suggest that Neanderthals never truly disappeared — they were absorbed. Their legacy lives on in our DNA, reshaping our understanding of what it means to be human.

A major breakthrough in Maya archaeology has emerged from Caracol, Belize, where the University of Houston team uncovered the tomb of Te K'ab Chaak—Caracol’s first known ruler. Buried with elaborate jade, ceramics, and symbolic artifacts, the tomb offers unprecedented insight into early Maya royalty and their ties to the powerful Mexican city of Teotihuacan.

A university student on a fossil-hunting field trip in Dorset made a stunning discovery: a 145-million-year-old jawbone belonging to a previously unknown mammal species with razor-like teeth. With the help of CT scanning, 3D printing, and expert analysis, the fossil was revealed to be Novaculadon mirabilis, a multituberculate that lived alongside dinosaurs. This is the first find of its kind from the area in over a century, and the fossil’s preservation and sharp-toothed structure are offering new insights into early mammal evolution — all thanks to a beach walk and a sharp eye.
