This 2023 astronaut photo shows three glaciers merging into a single massive ice mass in the Karakoram mountains. The stripy glaciers have gained ice in recent decades, despite the effects of human-caused climate change.

A new study shows how math helps explain why babies nap erratically, teens stay up late, and older adults wake earlier. Researchers expanded the classic two-process sleep model by adding the effects of light exposure, un...

Scientists developed a computational "aging clock" that measures the biological age of brain cells and identifies compounds with rejuvenating potential. By analyzing gene activity from healthy and neurodegenerative brain...

The tiny 'backward' brain of an ancient sea creature hints that spider ancestors might have gotten their start in the ocean.

A new study warns of "AIPasta," a strategy that uses generative AI to craft many slightly different versions of false claims to mimic widespread public belief. Unlike traditional CopyPasta, which repeats the same message...

A new study reveals how pleasant touch fosters social bonds between humans and rats by activating oxytocin signaling in the brain. Researchers found that repeated tickling of rats increased their vocalizations, preferenc...

An experimental birth control pill for males works by blocking sperm production, and it just passed its first safety test in humans.

The efficiency of quantum computers, sensors and other applications often relies on the properties of electrons, including how they are spinning. One of the most accurate systems for high-performance quantum applications...

Living through the Covid-19 pandemic may have accelerated brain ageing, even in people who were never infected, a new study finds. Brain scans of nearly 1,000 adults showed older, male, and disadvantaged individuals were...

Researchers have developed the first sort-in-memory hardware system capable of tackling complex, nonlinear sorting tasks without traditional comparators. Using a novel Digit Read mechanism and Tree Node Skipping algorith...

Reducing air pollution is critical for improving public health, but it has brought big climate trade-offs

Two minor meteor showers -- the Southern Delta Aquariids and Alpha Capricornids -- peak overnight on July 29-30, making it a great night for stargazing.

Children exposed to more green space before birth and during early childhood have a lower risk of neurodevelopmental disorders, a new study shows. Analysis of over 1.8 million mother-child pairs revealed reduced rates of...

A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar to claims made about 'Oumuamua. But experts have called it "nonsense".

AI chatbots often overestimate their own abilities and fail to adjust even after performing poorly, a new study finds. Researchers compared human and AI confidence in trivia, predictions, and image recognition tasks, sho...

Two AI models have achieved gold medal standard for the first time in a prestigious competition for young mathematicians - and their developers claim these AIs could soon crack tough scientific problems

Leaf-toed geckos were thought to be locally extinct on Rabida Island, but the diminutive reptiles have re-emerged after a campaign to eliminate invasive rats

For the more than 7 per cent of people over the age of 20 who don't have any of their own teeth, the only option is artificial substitutes. But an era of regrowing living teeth may now be almost upon us

The covid-19 pandemic changed our lives, and the world, in many ways - and now we are starting to understand its wider neurological effects

A 500-million-year-old sea creature called Mollisonia shared a similar brain structure to modern spiders, suggesting that arachnids first evolved in the sea

A 3D-printed hybrid drone can quickly transition between air and water thanks to variable pitch propellers. Watch a video of the drone in action.

Gray wolves were reintroduced in Yellowstone National Park in 1995 to help control the numbers of elk that were eating young trees, and it is finally paying off for quaking aspen.
