Brazilian monkeys offer lessons on how to return species to the wild
Efforts included letting golden lion tamarins roam free in urban U.S. parks. Restoring natural behaviors was key to their survival in the wild.
- Climate
Microbes that dwell in tree bark devour major climate gases
Hidden in plain sight, this huge community of tree-bark microbes dines on gases — such as methane — that warm Earth’s atmosphere.

Mummies suggest a way to help reintroduce cheetahs to Arabia
DNA from Arabian cheetah remains reveals that these now-extinct populations might be replaced by rewilding close cheetah relatives from northwest Africa.
- Physics
Could a person ever wield lightning as a weapon?
From the shocking powers of electric eels to laser-guided lightning, aiming electricity is more real than it sounds.
- Animals
As toddlers, chimps are major risk takers
Human kiddos are generally too closely supervised to be able to monkey around as much as young chimps. Instead, older kids — teens — are usually the bigger risk takers.
- Environment
Antarctica faces a green and weedy future
Warming is allowing alien species to invade a land that had been isolated for 30 million years. They now threaten local ecosystems unique to Antarctica.
- Plants
Scientists Say: Pollination
Plants call upon wind, water or helpful animals to carry out this crucial step of their life cycle.
- Fossils
Prehistoric ‘sea’ monster also lurked in rivers, data show
A 66-million-year-old fossil tooth turned up alongside remains of a T. rex and ancient crocodile. This shows some mosasaurs roamed into rivers.
- Tech
Scientists Say: Cryogenic
This deep-frozen field of science allows conservation biologists to preserve the DNA of endangered species and more.

You need to eat protein — but the right mix really matters
All proteins are not equal, research is showing. So while most Americans get plenty of protein, they might not be eating the most nutritious blend.

Let’s learn about Tyrannosaurus rex
These fearsome predators truly were enormous — with the bone-crushing bite power to match.

Lions have a second roar that scientists have only just discovered
This insight from machine-learning analyses of recordings of calls in the wild might help detect where lions are declining.
