- Fossils
American crocs seem to descend from kin that crossed the Atlantic
A fossil hints that early crocodiles crossed over from Africa, millions of years ago, to colonize a new land.
- Agriculture
Scientists Say: Carbohydrate
Carbohydrates are molecules with carbon, oxygen and hydrogen. Animals break down these chemicals in food to get energy.

You don’t see as much color as you think
It might seem like we live in a world full of color. But when scientists flip it into black and white, most people never notice the switch.
- Humans
Let’s learn about early humans
Homo sapiens are the last member left of our genus. But many other species of early humans existed before us.
- Animals
Viral scents? Dogs sniff out coronavirus in human sweat
Researchers train dogs to sniff out COVID-19. In the United Arab Emirates, sniffer dogs have already begun identifying infected passengers at airports.
- Animals
To figure out your dog’s ‘real’ age, you’ll need a calculator
What’s your dog’s human-equivalent age? Just multiply how old it is times seven, right? Uh, no. And here’s why.
- Animals
Superblack fish can disappear in the deep sea’s darkness
Some fish that live in the ocean’s depths are superblack due to a special layer of light-absorbing structures in their skin.
- Animals
Dolphins can learn from their peers how to use shells as tools
Some bottlenose dolphins seem to look to their peers, rather than mom, to learn how to trap prey in shells.
- Physics
Flying snakes wriggle their way through the air
Flying snakes go tens of meters (yards) without wings. They do it by undulating back and forth and up and down, a new study shows.
- Fossils
Early dinosaurs may have laid soft-shelled eggs
Scientists for the first time have turned up evidence of fossils from soft-shelled dinosaur eggs. This has scientists rethinking how dinosaur eggs evolved.
- Ecosystems
Scientists Say: Deforestation
Trees slurp up carbon dioxide and help keep our planet cool. But deforestation cuts those trees down in large numbers.
- Earth
On an Alaskan glacier, little green moss balls roll in herds
Oval balls of moss, nicknamed ‘glacier mice,’ roll across some glaciers. A new study explores the mysteries behind their herd-like motion.
