New research suggests some catastrophic event—such as a natural disaster or a virus—killed the world's last known population of mammoths on Wrangel Island

The frog saunas are easy to make and cost around $50 to put together.

'Frog Saunas' May Be the Key to Saving Amphibians From a Deadly Fungal Infection

Providing frogs with sun-warmed bricks inside mini-greenhouses can help them recover from chytrid and make them more resilient against the disease in the future, a new study finds

Captured by the Hubble Space Telescope, the heliosphere of a young star, LL Orionis, collides with an interstellar medium of dust. A similar event with our own sun, researchers say, might have occurred between two and three million years ago.

A Giant Interstellar Cloud May Have Once Enveloped Earth, Potentially Causing Ice Ages

Astronomers suggest this cold, dense cloud compressed our sun's protective field between two and three million years ago, leaving the Earth exposed to cosmic material

Newly examined fossils suggest monotremes—egg-laying mammals—were once much more abundant in Australia than they are today.

Meet the 'Echidnapus,' an Extinct Creature That Resembles Both the Echidna and Platypus of Today

The species is among three newly identified monotremes, or egg-laying mammals, discovered from fossils in Australia that are shedding light on the odd animals' evolution

Flamingos were nearly hunted to extinction for their feathers by the early 1900s. But, thanks in part to conservation and habitat restoration efforts, they're making a comeback in Florida. This flamingo was spotted in Miami Beach in 2018.

More Than a Century Ago, Flamingos Disappeared From Florida. Now, They're Coming Home

Likely transported by Hurricane Idalia last August, more than 100 of the pink birds were counted in a February census in the Sunshine State, where they are considered a native species

Owner Andreas Pernerstorfer thought he'd found a piece of wood, but then he remembered something his grandfather had said about finding teeth in the cellar decades ago

This illustration shows how the two-inch-long, curved teeth may have protruded from the extinct salmon's face.

These Massive, Extinct Salmon Had Spiky Teeth Like a Warthog's Tusks

For decades, scientists thought the teeth pointed downward, similar to those of a saber-toothed cat, but now they believe the fish's chompers jutted out sideways

Female northern white rhinos Najin and Fatu are the last of their species and reside at the Ol Pejeta Conservancy in Kenya.

World's First IVF Rhino Pregnancy Could Save a Nearly Extinct Subspecies

Only two northern white rhinos remain, but the new reproductive breakthrough may pull them back from the brink of erasure

The 2023 Doomsday Clock on display before a Bulletin of the Atomic Scientists event on January 24, 2023. The Bulletin has been setting the clock since 1947 based on analysis of threats facing humans from technologies people have made. 

Doomsday Clock Stays at 90 Seconds to Midnight Amid Climate Change, War and A.I.

For the second year in a row, the clock is the nearest it has ever been to signaling our total annihilation

To understand Elma's life, researchers cut her tusk lengthwise and took samples to study the elements present in the ivory.

Meet Elma, a Woolly Mammoth Who Roamed Far and Wide More Than 14,000 Years Ago

By analyzing a fossilized tusk, scientists have pieced together the animal's movements

What Caused the Mysterious Extinction of 'Giganto,' the World's Largest Ape?

The massive primates were unable to shift their diet to keep pace with a changing climate, according to a new study, forcing them to eat less nutritious bark and twigs

A California grizzly bear specimen at the Santa Barbara Museum of Natural History. The brown bear subspecies went extinct around 1924.

California Grizzlies Weren't as Big—or Bloodthirsty—as People Once Thought

The now-extinct bears were mostly vegetarians and measured about the same size as today's North American grizzlies

This A.I.-generated illustration shows what some of the undiscovered extinct birds might have looked like.

Humans May Have Driven Twice as Many Bird Species to Extinction as Previously Thought

Statistical modeling of undiscovered extinctions suggests 1,430 bird species have disappeared during modern human history

A De Winton's golden mole. A member of the species hadn't been definitely seen since 1936.

Scientists Uncover a Golden Mole Species Thought to Be 'Possibly Extinct'

A scent-detecting dog led the team to the discovery in South Africa, and traces of mole DNA helped confirm it

The jawbone likely belonged to a Columbian mammoth.

Fossil Hunter Pulls Massive Mammoth Jawbone Out of Florida River

John Kreatsoulas, who made the discovery while diving in southwest Florida, initially thought the 60-pound mandible was a log

Dust from the Chicxulub impact may have plunged the planet into a cold, dark winter and halted photosynthesis.
