‘Woolly mice’ were just a start. De-extinction still faces many hurdles
Scientists created transgenic mice with woolly mammoth–like traits. But does it really bring us closer to bringing back woolly mammoths?

An ancient bone recasts how Indigenous Australians treated megafauna
A new look at cuts on a giant kangaroo bone reveal First Peoples as fossil collectors, not hunters who helped drive species extinct, some scientists argue.

Dietary evidence bolsters Clovis hunters’ reputation as mammoth killers
Mammoths made up as much as 40 percent of the ancient North Americans’ diet, a chemical analysis of human remains reveals.
- Paleontology
Sloths once came in a dizzying array of sizes. Here’s why
A new fossil and DNA analysis traces how dozens of sloth species responded to climate shifts and humans. Just two small tree-dwelling sloths remain today.

What the longest woolly rhino horn tells us about the beasts’ biology
A nearly 20,000-year-old woolly rhino horn reveals the extinct herbivores lived as long as modern-day rhinos, despite harsher Ice Age conditions.
- Paleontology
Giant camel-like creatures lived thousands of years longer than once thought
Fossilized teeth from two ancient megafauna suggest they roamed Brazil 3,500 years ago. The find “opens the door to rewrite South American history.”

The last woolly mammoths offer new clues to why the species went extinct
The last population of woolly mammoths did not go extinct 4,000 years ago from inbreeding, a new analysis shows.
- Genetics
Freeze-drying turned a woolly mammoth’s DNA into 3-D ‘chromoglass’
A new technique for probing the 3-D structure of ancient DNA may help scientists learn how extinct animals functioned, not just what they looked like.

The story of dire wolves goes beyond de-extinction
Some question whether the pups are really dire wolves, or just genetically tweaked gray wolves. But the technology could be used to help at-risk animals.

These are our favorite animal stories of 2024
Pigeons that do somersaults, snakes that fake death with extra flair and surprised canines are among the organisms that enthralled the Science News staff.

Of frogs and the people who love them
Editor in chief Nancy Shute discusses frogs and chytrid fungus, trilobite fossils and a dinosaur named after the Norse god of mischief.

Humans, not climate change, may have wiped out Australia’s giant kangaroos
About 40,000 years ago, giant kangaroos vanished Down Under. Dental analyses suggest a varied diet, meaning climate change was not the main cause.
