These Tiny Ants Crawled All Over Larger Ants and Licked Them Clean. Scientists Aren’t Sure How This Behavior Benefits Any of Them

After witnessing the interactions in an Arizona desert, a Smithsonian researcher suggests that the little ants picked off tasty treats and that the big ants got thoroughly groomed in hard-to-reach places

Biologists with the California Department of Fish and Wildlife are working hard to eradicate nutria from the state.

Large Invasive Rodents Are Wreaking Havoc in California. New Research Suggests Someone Deliberately Introduced Them

Genetic testing revealed that nutria living in California since 2017 are most closely related to a population in central Oregon—too far for the creatures to have traveled on their own

How Do Different Psychedelics Affect the Brain? Scientists Analyzed More Than 500 Neural Scans to Find Out

A new study suggests that four psychoactive compounds work in surprisingly similar ways, and that they break down the separation between how we think internally and how we perceive the outside world

Smell influences food intake in cats, according to a new study.

Does Your Cat Always Leave Behind a Half-Full Bowl of Food? New Research Points to Why Our Furry Friends Can Be Such Picky Eaters

A new study suggests that domestic cats get bored of monotonous meals. Switching up their food—or even just nearby scents—could help them join the clean plate club

The clitoris is larger than most people think, and much of the organ is internal.

Scientists Just Made the Most Complete Map of the Clitoris’s Sensory Nerve Network. Here’s What They Found

Cultural taboos around female sexuality have hindered research on the organ. But a new study provides pivotal insights that can inform important surgeries and health care

Nearly 200 hippos are estimated to roam in Colombia.

Colombia Plans to Euthanize Dozens of ‘Cocaine Hippos,’ Descendants of Animals Brought by Notorious Drug Trafficker Pablo Escobar

If nothing is done to control the invasive creatures, officials estimate the population could grow to 1,000 animals by 2035. So, they aim to cull about 80 individuals later this year

When male greater sage grouse attempt to attract a mate, they puff up their chest, droop their wings and fan their tail feathers into a starburst shape.

One of the American West’s Most Iconic Birds Is Attempting to Mate Near a Dangerous Airport. Could Robo-Birds Help Save Them?

Conservationists are deploying dancing animatronic birds to lure male greater sage grouse away from the Jackson Hole Airport, where dozens of the creatures have been struck and killed by planes

This Nearly 300-Million-Year-Old Mummified Reptile Reveals the Evolutionary Origins of How We Breathe

Unusually well-preserved fossils have provided the earliest known evidence of a land vertebrate that could pump air in and out of its chest using muscles between the ribs—the same strategy used by modern mammals, reptiles and birds

An artificially colored human B cell, the type of immune cell that caused all three autoimmune diseases in the patient

In a First, This Personalized Cell Therapy Treated Three Life-Threatening Autoimmune Diseases in One Patient

The patient was bedridden and needed daily blood transfusions, and she had tried nine different therapies that didn’t bring lasting effects. So, researchers modified some of her immune cells so they would attack her faulty cells

Artemis 2's Orion capsule splashed down in the Pacific Ocean off the coast of San Diego.

After Nearly 80 Years of Doubt, Scientists Say a Spear Lodged Between Elephant Ribs Offers Evidence That Neanderthals Hunted Big Game

In 1948, amateur archaeologists unearthed the remains, which should have shifted researchers’ views of Neanderthals. But poor documentation sowed skepticism in the scientific community

Adult emperor penguins have waterproof feathers. But they replace all of them every year during their catastrophic molt, which makes them vulnerable.

As Their Antarctic Habitat Melts Away, Emperor Penguins Are Now Considered an Endangered Species

The International Union for Conservation of Nature predicts that the birds’ population could be cut in half by the 2080s. The organization also changed the statuses of Antarctic fur seals and southern elephant seals
