Powerful magnets could unlock detection of high-frequency gravitational waves

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection experiments could function as highly precise gravitational wave detectors, thereby establishing an entirely ...

First hominin fossils recovered from submerged Sundaland

The Sunda Shelf is home to a rich Pleistocene hominin fossil record, including specimens of Homo floresiensis, Homo luzonensis, Homo erectus, and archaic Homo. Much of the Sunda Shelf is submerged. At times during the Pleistocene, ...

Will asteroid 2024 YR4 hit the moon?

Asteroid 2024 YR4 made headlines earlier this year when its probability of impacting Earth in 2032 rose as high as 3%. While an Earth impact has now been ruled out, the asteroid's story continues.

New 'smart capsule' tracks health of the GI tract

Scientists are increasingly finding that the gastrointestinal (GI) tract plays a vital role in our overall health. While its main functions center around digestion, the GI tract is also involved in the production of hormones, ...

Novel yet simple model provides smooth answer to friction mystery

Atoms slip against one another, eventually sticking in various combinations. Tectonic plates do the same, sliding across each other until they stick in a stationary state. Everything from the tiniest particles to unfathomably ...

Scientists develop stable all-perovskite tandem solar cells

A research group led by Prof. Ge Ziyi from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has developed an innovative strategy to alleviate NiOx corrosion, enabling ...

The 'born-again dynamo' of the sun's elder twin

An international team, led by Instituto de Astrofísica e Ciências do Espaço (IA) researcher Ângela Santos, has made the first measurement of the magnetic field of β Hydri, a nearby aged solar analog subgiant star. This ...

Killer whales make seaweed 'tools' to scratch each other's backs

Killer whales have been seen detaching lengths of seaweed and using them to massage each other—the first evidence of tool-making by marine mammals. The whales bite off the end of a kelp stalk, position it between themselves ...

Orbiter pair expands view of Martian ionosphere

Like Earth, Mars is surrounded by an ionosphere—the part of its upper atmosphere where radiation from the sun knocks electrons off of atoms and molecules, creating charged particles. The Martian ionosphere is complex and ...

AI's arrival at work reshaping employers' hunt for talent

Predictions of imminent AI-driven mass unemployment are likely overblown, but employers will seek workers with different skills as the technology matures, a top executive at global recruiter ManpowerGroup told AFP at Paris's ...

Decoding high energy physics with AI and machine learning

In the world of particle physics, where scientists unravel the mysteries of the universe, artificial intelligence (AI) and machine learning (ML) are making waves with how they're increasing understanding of the most fundamental ...
