Early humans were bringing fire into caves 1.8 million years ago

A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was likely carried in and maintained by human ancestors. The discovery pushes back the timeline for fire use and reveals surprisingly sophisticated behavior long before humans could create fire on demand.

One of the world’s most popular weedkillers may be fueling deadly superbugs

Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller. The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far beyond healthcare settings.

A tiny diamond defect could reveal a mysterious new kind of magnetism

A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency of antiferromagnets with some of the useful electronic properties of traditional magnets, making them promising candidates for next-generation electronics.

A rare interstellar visitor triggered a SETI search for alien technology

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural origin and showcased how future interstellar visitors can be investigated for signs of intelligent life.

This four-winged dinosaur may have terrorized Earth's earliest birds

A newly discovered feathered dinosaur called Jian changmaensis may be the missing predator responsible for mysterious piles of crushed prehistoric bird bones in China. The four-winged glider, a close cousin of Velociraptor, helps reveal how early birds and their dinosaur relatives shared the same ancient landscape.

Scientists open a million-year-old time capsule hidden beneath New Zealand

A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived.

Scientists say most people need more protein than current guidelines suggest

A new review suggests that doing more exercise and eating more protein than current minimum recommendations may help people stay stronger, sharper, and more independent as they age. The goal isn't building a beach body—it's extending healthspan and maintaining the ability to fully enjoy life for decades longer.

More trees can mean fewer birds, new study reveals

Trees planted to protect farmland from wind may not be the biodiversity boost many assume. In Japan’s wetland farming landscapes, shelterbelts benefited some birds but sharply reduced grassland and wetland species that need open space. Researchers found grassland bird abundance dropped by more than 70% near shelterbelts.

Ebola and hantavirus can start like the flu but turn deadly fast

Two dangerous viruses are back in the spotlight, reminding health officials how quickly infectious diseases can become serious threats. Hantavirus, often linked to rodents, can cause severe heart and lung complications and has no specific treatment or vaccine, while certain strains can even spread between people. Ebola remains one of the world's most feared diseases, with some outbreaks killing up to half of those infected, although vaccines and antivirals have improved outcomes for some strains.
