This AI can predict ship-sinking ‘freak’ waves minutes in advance

Rogue waves are freakishly large ridges of water known for rising out of the blue to ambush hapless ships and beachgoers. But a new artificial intelligence model can predict most of these surprising swells up to five minutes in advance,…

Something weird is happening to Earth’s inner core

An illustration of the Earth sliced in half to expose a glowing inner core

Something strange is happening at Earth’s center. Decades of earthquake data show that Earth’s inner core has been rotating slower than its mantle and surface since around 2010, researchers report June 12 in Nature. The study appears to confirm a…

Landfills belch toxic ‘forever chemicals’ into the air

What’s dumped into a landfill is supposed to stay there, but a new study finds that toxic “forever chemicals” are wafting from the waste into the air. Per- and polyfluoroalkyl substances, or PFAS, have been detected in the gas exuded…

A black hole made from pure light is impossible, thanks to quantum physics

An artistic rendering shows a glowing orb of light with light beams streaming in

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re often formed when a star’s core implodes at the end…

A Dune-inspired spacesuit turns astronaut pee into drinking water

In the science-fiction series Dune, the desert-dwelling Fremen of the arid planet Arrakis recycle their body’s moisture using specially designed outfits called stillsuits. Inspired by such imaginings, a new prototype spacesuit converts astronauts’ urine into drinkable water, researchers report July…

World record speeds for two Olympics events have fallen over time. We can go faster

Usain Bolt crouches next to a digital display showing his new world record while pointing to a crowd in a stadium

Ready, set, go break a record. As elite athletes compete for top accolades in the 2024 Summer Olympics in Paris, at least a few world records will undoubtedly fall. But some of the Olympics’ speediest events — the 100-meter dash…

The second law of thermodynamics underlies nearly everything. But is it inviolable?

Art of four eggs, from left to right, getting progressively more cracked. In the far right egg, it

In real life, laws are broken all the time. Besides your everyday criminals, there are scammers and fraudsters, politicians and mobsters, corporations and nations that regard laws as suggestions rather than restrictions. It’s not that way in physics. For centuries,…

In spring 2022, a handful of red foxes in Wisconsin were behaving oddly. Veterinary pathologist Betsy Elsmo learned that a local wildlife rehabilitation center was caring for foxes with neurological symptoms like seizures, tremors, uncoordinated movements and lethargy. But tests…

Strange observations of galaxies challenge ideas about dark matter

Streaks around the galaxy cluster Abell 370 reveal more distant galaxies whose light has been bent and distorted by an effect called gravitational lensing.

Head-scratching observations of distant galaxies are challenging cosmologists’ dominant ideas about the universe, potentially leading to the implication that the strange substance called dark matter doesn’t exist. That’s one possible conclusion from a new study published June 20 in The…

Why this year’s climate conditions helped Hurricane Beryl smash records

Hurricane Beryl, the Atlantic Ocean’s first hurricane in 2024, began roaring across the Caribbean in late June, wreaking devastation on Grenada and other Windward Islands as it grew in power. It’s now swirling on like a buzzsaw toward Jamaica and…
