Earth
We summarize the week's scientific breakthroughs every Thursday.
- Earth
Earth’s mantle may be hotter than thought
Earth’s mantle is warmer than previously thought, suggests a new experiment that better accounts for water content in rocks.
- Planetary Science
Saturn’s ‘Death Star’ moon may not conceal an ocean after all
A lack of cracks on Mimas suggests that the icy moon of Saturn doesn’t conceal a subsurface ocean of liquid water.

- Environment
Most fish turned into fishmeal are species that we could be eating
Millions of tons of food-grade fish are turned into fishmeal for aquaculture and agriculture.
- Earth
Newly identified continent Zealandia faces a battle for recognition
Geologists make the case for a new continent, dubbed Zealandia, found largely submerged beneath the southwestern Pacific Ocean.
- Quantum Physics
Readers amazed by Amasia
Quantum spookiness, shifting landmasses and more in reader feedback.
- Animals
Too many stinkbugs spoil the wine
Stinkbugs can ruin wine if enough are accidentally processed alive with the grapes. Three or fewer stinkbugs per grape cluster don’t have a noticeable effect on red wine.
- Chemistry
New, greener catalysts are built for speed
Researchers are designing catalysts to move chemical reactions without using precious metals, or at least using less of them.
- Climate
Antarctic sea ice shrinks to record low
The Antarctic sea ice extent has reached a new low just two years after hitting a record high.
- Ecosystems
Seagrasses boost ecosystem health by fighting bad bacteria
Seagrasses might reduce bacteria levels in ocean water.
- Physics
Sound waves could take a tsunami down a few notches
A tsunami’s ferocious force could be taken down a few notches with a pair of counter waves.
- Climate
Desert songbirds increasingly at risk of dehydration
With no efforts to curb climate warming, hot spots in the U.S. Southwest could turn uninhabitable for some songbirds.
