A glowing new way to measure antibodies
Researchers invent a way to detect and measure antibodies with glowing proteins. Antibodies can mark exposure to various diseases.
- Life
Let’s learn about alligators and crocodiles
Alligators and crocodiles seem similar — but they live in different places and look different, too.
- Chemistry
Stinky success: Scientists identify the chemistry of B.O.
They turned up the enzyme in bacteria behind that underarm stench. Understanding how it works could pave the way to new types of deodorant.
- Animals
A single chemical may draw lonely locusts into a hungry swarm
Swarms of locusts can destroy crops. Scientists have discovered a chemical that might make locusts come together in huge hungry swarms.
- Microbes
Some deep-seafloor microbes still alive after 100 million years!
Some starving microbes nap while awaiting their next meal. For some living miles below the ocean surface, that nap may exceed 100 million years.

Analyze This: Hurricanes may help lizards evolve better grips
Lizards have larger toepads in areas that tend to have higher hurricane activity. This suggests high winds select for those that can hang tight.

A Hong Kong man got the new coronavirus twice
His is the first confirmed case of reinfection with this virus. His second bout was detected by accident, because he showed no symptoms.
- 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.
- 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.
- 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.

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.

For teens, big problems may lead to meaningful research
Several teens who competed at the Regeneron Science Talent Search applied their STEM know-how to solve problems they or their communities faced.
