Researchers found that specific brain circuits help decide which jobs bees perform as they age. When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties. The ...

Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the ...

Ancient sediment reveals that some of K'gari's deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the sacred lakes known as the .. ...

China's Chang'e-6 samples have uncovered a surprising difference between the Moon's two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth's magnetosphere slows the particles that reach the near side. Noble gases ...

Ancient DNA from China's vast 4,000-year-old Shimao settlement is revealing how one of East Asia's earliest complex societies was organized. Researchers found that its people were largely descended from local Yellow River farming communities, but ...

Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals' stomachs. All four infected whales showed serious digestive damage, including inflammation, ...

Two elephant-sized South American sauropods were unusually well built for standing on their hind legs. Digital tests showed that their robust femurs handled the enormous forces better than those of larger species, especially while the dinosaurs were ...

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth's climate. Scientists warn that this widespread deoxygenation is closely ...

Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent's unique mammals evolved. The discovery challenges the idea that Australia ...

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have .. ...
