The quadrupedal machine finished the course in a solid four hours, 19 minutes and 52 seconds—and on just one battery charge

Independent auditors are emerging as a key part of plans to rein in frontier AI. But the systems are evolving faster than the methods used to evaluate them

Giving old mice semaglutide—commonly sold as Wegovy or Ozempic—extends their lifespan remarkably, a new study finds

The Red Planet’s global geography of low-lying northern plains and rugged southern highlands seems to have surprisingly deep roots, with profound implications for Mars’s ancient habitability

Growing crystals “like alchemy,” researchers plotted out the ideal site within the lattice to build a nuclear clock

One in 7,000 people carry this gene mutation

Scientists analyzing modern genomes may have found a long-lost branch of the human family tree

Moonshot AI’s Kimi K3 shows how opening a model to outsiders can turn other companies’ computing power into a competitive advantage

Bacteria send protein packages to dormant neighbors to endure antibiotic attack

A new model uses a routine ECG to flag people at high risk of sudden cardiac death—and reveals a warning sign in the heart’s electrical activity

Mapping their starting point like bees do helps autonomous drones find their way

A study of people who underwent surgery to treat epilepsy suggests the hippocampus may process words and speech when people are under general anesthesia, even though the study participants didn’t remember them

An engineered E. coli strain survived after one amino acid was designed out of many of its ribosomal proteins—an early test of whether life’s chemistry can be simplified

When an earthquake rupturing along a fault hits a barrier, it creates a seismic signature called the “stopping phase.” Scientists have isolated this and could use it to better predict earthquake risk

Researchers pinpointed the purpose of mysterious heart neurons in mice—and humans have them, too

Medieval poets, including a Japanese noble, provided key descriptions to track down solar events

The arrival of AI-generated research papers marks a turning point that could radically accelerate discovery—or drown it in automated mediocrity

Scientists have finally pinned down the mechanism behind cold- and menthol-sensing proteins

The sun rode a massive galactic migration wave to the Milky Way’s suburbs

Four worlds around a small, dim star are challenging theories of planet formation

Lung cancer tumor cells in mice communicate with the brain, sending signals to deactivate the body’s immune response, a study finds

A wobbling jet from a giant, voracious black hole is suppressing star formation in a distant galaxy—and astronomers have never seen anything quite like it before

New work pinpoints the origins of the planet Theia, whose ancient collision with Earth likely produced the moon

A fresh analysis of old data has found rich organic chemistry within the hidden ocean of Saturn’s moon Enceladus
