We summarize the week's scientific breakthroughs every Thursday.
- Life
10 billion snow crabs have disappeared off the Alaskan coast. Here’s why
In the eastern Bering Sea, the snow crab population plummeted after a marine heat wave in 2018. The crabs may have starved, a new study finds.
- Climate
Róisín Commane sleuths out greenhouse gas leaks to fight climate change
From New York City to the Arctic, atmospheric chemist Róisín Commane tries to account for the greenhouse gases in the air.
- Animals
A global report finds amphibians are still in peril. But it’s not all bad news
A survey of about 8,000 amphibian species provides the latest update on extinction risk trends stretching back to 1980.
- Animals
In noisy environs, pied tamarins are using smell more often to communicate
Groups of the primate, native to Brazil, complement vocalizations with scent-marking behavior to alert other tamarins to dangers in their urban home.
- Paleontology
New computer analysis hints volcanism killed the dinosaurs, not an asteroid
Scientists take a creative approach to investigating what caused the mass extinction 66 million years ago, but the debate is far from settled.
- Climate
‘Our Fragile Moment’ finds modern lessons in Earth’s history of climate
Michael Mann’s latest book, Our Fragile Moment, looks through Earth’s history to understand the current climate crisis.
- Earth
To form pink diamonds, build and destroy a supercontinent
The Argyle deposit in Australia formed about 1.3 billion years ago, a study shows, along a rift zone that sundered the supercontinent Nuna.
- Physics
A laser gyroscope measured tiny variations in the lengths of days on Earth
An underground gyroscope known as ‘G’ uses laser beams traveling in opposite directions to precisely measure Earth’s rotation.
- Oceans
‘The Deepest Map’ explores the thrills — and dangers — of charting the ocean
A new book follows the race to map the seafloor, documenting how it’s done, why and what a clear view of the deep sea could mean for Earth’s future.
- Climate
What’s driving an increasing number of hurricanes to rapidly intensify?
Hurricane Lee is just the latest storm to explode in power in only hours. The phenomenon is linked to a warming world.
- Earth
When discussing flora and fauna, don’t forget ‘funga’
Conservation efforts often overlook fungi. That can change by using “mycologically inclusive language,” researchers say.
- Earth
How thunderstorms can spawn damaging ‘downbursts’
Powerful winds called downbursts are not the same as a tornado, but the damage they cause can be similar — and can hit with little warning.
