We summarize the week's scientific breakthroughs every Thursday.
- Life
Ancient giant eruptions may have seeded nitrogen needed for life
A new study bolsters the idea that on the young Earth volcanic lightning may have provided some materials that made it possible for life to emerge.
- Oceans
Satellite data reveal nearly 20,000 previously unknown deep-sea mountains
By looking for tiny bumps in sea level caused by the gravity of subsurface mountains, researchers have roughly doubled the number of known seamounts.
- Climate
Thawing permafrost may unleash industrial pollution across the Arctic
As the frozen ground warms due to climate change, industrial pollutants could flow free from thousands of sites across the Arctic.
- Plants
Ultrasound reveals trees’ drought-survival secrets
Scientists used ultrasound sensors and electrical probes to reveal how drought affects the tissues of living trees.
- Earth
A massive cavern beneath a West Antarctic glacier is teeming with life
A subglacial river has carved out the cavern beneath the Kamb Ice Stream, a West Antarctic glacier, and may be supplying nutrients necessary for life.
- Climate
Methane may not warm the Earth quite as much as previously thought
Methane absorbs both longwave and shortwave radiation, with competing effects on climate, a study finds. The gas remains a potent warmer of the planet.
- Earth
The Great Salt Lake is shrinking. What can we do to stop it?
A dropping lake level affects agriculture, public health and the environment — but water conservation can halt the decline.
- Climate
The summer of 2021 was the Pacific Northwest’s hottest in a millennium
Tree ring data from the Pacific Northwest reveal that the region’s average summer temperature in 2021 was the highest since at least the year 950.
- Climate
‘Flash droughts’ are growing increasingly common
Droughts are forming faster more often in much of the world due to climate change, a new study finds.
- Environment
Satellite imagery reveals ‘hidden’ tornado tracks
Twisters that churn over barren landscapes leave scars that are invisible to human eyes but are detectable with infrared light.
- Climate
How an Indigenous community in Panama is escaping rising seas
The Indigenous Guna peoples' relocation from Panama could offer lessons for other communities threatened by climate change.
- Climate
Baseball’s home run boom is due, in part, to climate change
Higher air temperatures led to an average of 58 more home runs each MLB season from 2010 to 2019, a study shows.
