A new once-daily weight-loss pill called orforglipron delivered better weight loss and blood sugar improvements than the leading oral semaglutide in a major clinical trial. The tablet could offer a more convenient alternative to injectable drugs like ...

Researchers have created an AI-based simulation that makes it much faster to model how neutron star mergers produce many of the universe's heaviest elements. The new tool could improve predictions of these powerful explosions while helping scientists ...

Researchers rebuilt long-extinct versions of a crucial enzyme that helps make nitrogen available to life, offering an unprecedented glimpse into Earth's distant past. The breakthrough could aid the search for extraterrestrial life while helping ...

A centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display surprisingly deep quantum behavior. The discovery could help solve the mystery of strange metals while opening new ...

A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, . ...

Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies ...

Scientists at the University of Illinois Chicago have turned an unlikely source into a potential new weapon against cancer: bacteria that naturally live inside tumors. They developed a peptide called aurB, inspired by a bacterial protein, that ...

Almost half of the takeaway meals tested contained more salt than advertised, with some dishes delivering nearly twice the recommended daily limit in a single serving. Surprisingly, classic fish and chips ranked among the lowest-salt options, while . ...

A new study suggests human hair grows in a way scientists never expected. Researchers found that hair is pulled upward by coordinated cell movements inside the follicle rather than simply being pushed out by dividing cells at the root. Advanced 3D .. ...
