Natural compound could fight rheumatoid arthritis at its source

A natural compound extracted from a medicinal plant has shown surprising promise against rheumatoid arthritis. In rats, it reduced joint swelling, protected cartilage, and calmed the immune responses responsible for chronic inflammation. Scientists discovered that the compound works by targeting a specific protein and restoring balance to fatty acid metabolism, revealing a previously underexplored way to fight the disease.

A simple 15-minute treatment could help patients avoid carpal tunnel surgery

A simple, steroid-free procedure could offer lasting relief for people struggling with carpal tunnel syndrome, potentially helping them avoid surgery. In a clinical trial involving 63 patients, researchers found that ultrasound-guided hydrodissection, which uses fluid to free a compressed nerve in the wrist, provided longer-lasting improvements in pain, numbness, and hand function than traditional steroid injections.

Illegal fishing is thriving in African waters—a satellite system could help change that

A patrol boat off the coast of Gabon intercepted three trawlers in July 2026, inside the Grand Sud Reserve. This is one of West and Central Africa's largest marine reserves, where industrial trawling is banned. None of the trawlers held a valid license. The patrol found them because analysts at the nonprofit Global Fishing Watch had studied satellite data and worked out where to look.

People are taking an unapproved weight-loss drug. AI found something surprising

Researchers analyzing nearly 150,000 Reddit posts uncovered unexpected symptom reports linked by users to unapproved versions of retatrutide, including increased appetite, sleep disturbances, and elevated heart rates. The findings differ from clinical trial results and highlight how AI could help identify potential drug safety signals that warrant further investigation.

Horror films exploit how human vision works to deliver movies' best scares

Imagine you're in the movie theater watching 2018's "Hereditary." During one of the film's most unsettling sequences, the main character, Peter, wakes up in bed disoriented. As he sits up, you hear a couple of gasps from others in the audience. The camera stays locked on Peter as he moves through his house and enters the dim living room.

A rock plunged 90 kilometers into Earth and revealed something unexpected

Scientists discovered a rock in Papua New Guinea that plunged more than 90 kilometers beneath Earth's surface, revealing a bizarre temperature pattern that challenges established theories of Earth's interior. The unexpected shift from unusually hot to relatively cold conditions could transform our understanding of tectonic plate movements, earthquakes, and volcanoes.

Student motivation and responsibility shown to be key to tackling bullying in physical education

Physical education has traditionally been one of the most eagerly awaited classes of the school day, since it lets students get out of the classroom, move around and interact with their classmates in a different way—conditions that are conducive to learning values such as camaraderie and cooperation. However, the physical exposure and the dynamics of interaction, comparison and competition that the class can entail still make some students uneasy, and, in settings where bullying occurs, turn it into a potentially unsafe space.

AI listens to bee buzzes to monitor activity without lethal traps

Populations of many pollinators, including bumblebees, have been crashing over the last few decades, thanks to the widespread use of chemical pesticides, loss of habitat and the acceleration of climate change. But it can be hard to know just how bad the problem is, or whether conservation strategies are helping, without relying on lethal traps—which can kill tens of thousands of bees in order to get an accurate count of their populations.

New optogenetic tool inhibits activity in neurons and heart muscle cells

Researchers from Ruhr University Bochum have partnered with colleagues in Göttingen, Berlin, Paris and Essen to develop new optogenetic tools that can selectively inhibit cellular activity through light. These tools could help investigate diseases in which the balance between excitation and inhibition is disrupted, such as cardiac arrhythmias.

James Webb telescope discovers surprising trove of metals around the Milky Way's supermassive black hole

The Milky Way's supermassive black hole is surrounded by a surprising trove of heavy metals, according to new observations by the James Webb Space Telescope (JWST). The metals may offer new clues about how Earth got its share of heavy elements — but it could also make one of the greatest mysteries about our local black hole even harder to solve.In astronomy, metals refer to any element heavier than hydrogen or helium, with common examples including oxygen, carbon, iron or gold. These elements are forged through nuclear fusion in the hearts of stars that are reaching the ends of their lives, before being sprayed into space and incorporated into new generations of stars. Scientists say the mat...

Extremely rare Viking Age coin from the reign of 'Olaf the Holy' may have been 'held in the king's own hand'

A rare silver coin minted during the reign of a famous Viking king has been discovered in a massive hoard in Norway that now comprises 5,500 coins and counting.The coin is inscribed with the name of the Norwegian king Olaf Haraldsson, who ruled from 1015 to 1028 and, as St. Olaf or "Olaf the Holy," is considered the national saint of Norway.Fewer than 20 coins minted during Olaf's reign have ever been discovered, and the newfound coin is a "national treasure," according to a statement from the University of Oslo's Museum of Cultural History."Here we have a coin bearing the king's portrait and a cross, with another cross on the reverse," University of Oslo coin expert Svein Gullbekk said in t...
