An artist's reconstruction of Edmontosaurus some 66 million years ago

Scientists Finally Know What This ‘Mummified’ Dinosaur Looked Like

A recent study suggests the unique geology of an area in Wyoming makes it a trove of unusually preserved fossils

The carpa uasi served as the bottom level of this building. It originally ended to the left of the arch.

This Inca Building—the Only Surviving Structure of Its Kind—Might Have Been Designed to Amplify Sound and Music

Researchers will use 3D modeling to assess what the “carpa uasi” in Huaytará, Peru, originally looked like and how sound traveled through it

A new study found that women with no history of heart disease can decrease their risk of disease with about half as much exercise as men.

Women Need About Half as Much Exercise as Men for the Same Heart Benefits, Study Suggests

Researchers analyzed the activity and health records of 85,000 U.K. adults over roughly eight years

The conference billed itself as the first to feature all A.I.-generated research.

A New Conference Presented Scientific Papers Written and Reviewed by A.I. as an Experiment. Here’s What Happened

While some researchers note the models made tasks more efficient, many scientists remain skeptical about using A.I. to author scientific work

Epiatheracerium itjilik lived in a forested lake habitat on Devon Island 23 million years ago. 

Scientists Discover ‘Frosty’ Polar Rhino That Roamed the Canadian Arctic 23 Million Years Ago

The newly identified species was small, hornless and possibly covered in fur, which would have helped it survive dark, cold winters above the Arctic Circle

Tim Andrews and his wife leave the hospital after he received the pig kidney transplant about nine months ago.

Pig Kidney Transplant Removed From Patient After a Record-Breaking 271 Days

Tim Andrews was the fourth patient in the United States to receive a pig kidney transplant. He will now return to dialysis and wait for a kidney from a human donor

The skin of the three-striped poison dart frog, Ameerega trivittata, contains a cocktail of lethal toxins that interfere with the function of key cell proteins. That’s a challenge for any prospective predator.

These Animals Eat Poisons and Don’t Die. Some Even Become Toxic in Turn

Critters consuming species that harbor deadly toxins have evolved a suite of clever strategies to keep out of harm’s way. Scientists are starting to unravel how these protections work on the molecular level

One of the stelae mentioning Ix Ch’ak Ch’een

Cool Finds

Archaeologists Decipher Crumbling Hieroglyphs to Reveal the Name of a Forgotten Maya Queen Who Ruled 1,400 Years Ago

Ix Ch’ak Ch’een reigned over the city of Cobá in Mexico’s Yucatan Peninsula. Historians didn’t know her name before they began translating a series of inscriptions discovered in 2024

For two days at the start of monsoon season on the Indian subcontinent, male Asian common toads (right) turn bright yellow, while females (left) stay brown.

For Two Days Each Year, These Drab Brown Toads Turn a Dazzling Neon Yellow—and Scientists Finally Know Why

When monsoon rains begin to fall on the Indian subcontinent, Asian common toads congregate at temporary puddles for a frenzied, two-day mating spree

New research reveals that Earth's Northern Hemisphere is growing darker faster than the Southern Hemisphere is.

Earth Is Getting Dimmer—and the Northern Hemisphere Is Losing Brightness Faster Than Scientists Expected

New research challenges the idea that the hemispheres’ matching brightness is a fundamental property of the planet

Psilocybe cubensis, a mushroom that produces the psychoactive compound psilocybin.

Magic Mushrooms Evolved Psilocybin Not Once, but Twice

Two different types of mushroom evolved the same psychedelic compound in completely unrelated ways, a recent study finds

Thousands of men died as Napoleon's army retreated from Russia in 1812.

Cold, Hungry and Thirsty, Napoleon’s Troops Also Suffered From Several Diseases as They Retreated From Russia

New research finds evidence of two previously undocumented infections that likely plagued the French emperor’s Grande Armée during the retreat from Moscow

The moai at the Rano Raraku site on Easter Island

New Research

Did Easter Island’s Mysterious Moai Statues Waddle to Their Final Locations? Here’s What That May Have Looked Like

Based on 3D modeling and testing on a moai replica, researchers think that small groups of people may have used ropes to “walk” the large statues across the island

Two T. rex dinosaurs square up for a fight in an illustration. Dinosaurs in the Cretaceous were thriving until the Chicxulub asteroid initiated a mass extinction.

The Dinosaurs of North America Were Thriving Up Until an Asteroid Wiped Them Off the Face of the Earth, Scientists Argue

A new study of dinosaur biodiversity challenges the belief that the megafauna were on their way out 66 million years ago

To capture snake strikes on video, scientists put medical gel on a stick and warmed it to mimic the body temperature of a mammal. Then, they waited for the snakes to attack.

Slow-Motion Videos Reveal What Really Happens When Snakes Bite

Different snakes put their own spin on striking their prey. Scientists captured the powerful attacks on camera

A mother breastfeeds a baby at home

Breastfeeding Has Long Been Linked to Reducing Cancer Risk. Scientists May Have Just Discovered Why

Patients with a history of breastfeeding showed higher levels of specialized immune cells in their breasts that may protect against malignant cancers

Human remains excavated in an ancient well in Croatia were likely those of ancient Roman soldiers, a new study suggests.

Seven Skeletons Found in a Croatian Well Were Likely Ancient Roman Soldiers Who Died During a Troubled Time for the Empire

The tall, adult men probably died during the battle of Mursa in 260 C.E., according to a new analysis of their remains

An illustration shows the types of megafauna that may have lived near Australia's Mammoth Cave about 50,000 years ago. From left to right: Murrayglossus hacketti, a giant long-beaked echidna; Procoptodon browneorum, the giant kangaroo whose bone is the subject of new research; Zygomaturus trilobus, a giant diprotodontid; and Thylacinus cynocephalus, a Tasmanian Thylacine

A Giant Kangaroo Bone Is Challenging the Idea That Humans Wiped Out Australia’s Megafauna

Indigenous Australians may have been early “paleontologists,” not big-game hunters, according to a new analysis

Storage jars found among the cargo known as Dor L1

New Research

Three Shipwrecks Discovered Off the Coast of Israel Shed New Light on the History of Iron Age Maritime Trade

An anchor, basket handles, jars and other artifacts were found among the cargoes at the three sites, the oldest of which dates to the 11th century B.C.E.

Of the 14 athletes studied in this research, ten competed in ultramarathons and ran up to about 7,000 miles over the course of the year.

How Far Is Too Far for Ultra-Endurance Athletes? This Study of Metabolism Found Out

Individual athletes ran an average of 4,000 miles over a year to help define the human body’s limit for energy expenditure
