Fires in the Amazon forest may melt sea ice in Antarctica
Satellite data reveal a link between the amount of black carbon in the atmosphere and rates of Antarctic sea ice loss in recent years.
- Animals
Some penguins save energy by riding ocean currents
When navigating home, Magellanic penguins alternate between heading straight back in calm waters and swimming with the flow in strong ocean currents.

Penguin poop gives Antarctic cloud formation a boost
Penguin poop provides ammonia for cloud formation in coastal Antarctica, potentially helping to mitigate the impacts of climate change in the region.
- Paleontology
Earth’s first waterfowl may have lived in Antarctica 69 million years ago
A few fossilized body parts hinted at an enigmatic bird's close ties to waterfowl like ducks and geese. A newfound skull may bolster that idea.
- Paleontology
Crystallized dino eggs provide a peek into the tumultuous Late Cretaceous
Definitively dating the age of a clutch of fossil dinosaur eggs at a famous site in China may let scientists link eggshell features to environmental shifts at the time.

An unexpected ice collapse hints at worrying changes on the Antarctic coast
The Conger Ice Shelf disintegrated in 2022. Satellite data leading up to the collapse hint at worrying changes in a supposedly stable ice sheet.
- Plants
A newly discovered gene helped this moss defy gravity
A gene called IBSH1 helped spreading earthmoss thrive at high gravity, hinting at how plants adapted to photosynthesize on land.
- Environment
See how aerosols loft through Earth’s sky
Aerosols, small particles in the atmosphere like salt and dust, may offset a third of human-caused climate warming, though their influence is fading.

Can geoengineering plans save glaciers and slow sea level rise?
As climate change melts West Antarctica’s glaciers, scientists are proposing bold ideas to avoid devastating sea level rise. Will they work?
- Earth
NASA images may help track sewage in coastal waters
Sewage-contaminated water absorbs certain wavelengths of light, leaving a signature that can be detected by space-based instruments, a new study finds.
- Climate
Hidden Antarctic lakes could supercharge sea level rise
An overlooked Antarctic water system could raise sea levels by more than 2 meters by 2300, computer simulations show.
