As artificial intelligence systems rapidly outgrow traditional academic benchmarks, researchers have unveiled an ambitious new test designed to probe the true limits of machine intelligence.

A new genetic analysis reveals that human females and Neanderthal males interbred far more than the reverse, for reasons that remain mysterious.

A rare celestial event will be taking place in the sky above California on Saturday night, as six planets are expected to be visible in what is being called a "planetary parade."

If you want to be as efficient as you possibly can be, build yourself a nice aerodynamic recumbent velomobile with a small e-bike assist motor this summer.

A new fossil discovery suggests that Earth's first mass extinction may have been far more sudden and severe than previously believed, reshaping our understanding of ancient ecosystems.

Quantum technologies, computers or other devices that operate leveraging quantum mechanical effects, rely on the precise control of light and matter. Over the past decades, quantum physicists and material scientists have been trying to identify systems that can reliably generate photons (i.e., light

A new bioengineered neuronal circuit board "BioConNet" allows scientists to artificially engineer human brain-like wiring at scale and can be used to engineer any possible circuit. The fully programmable, open-source system allows generation of large-scale ci…

It looks like a cartoon panda character hiding in plain sight on the ocean floor. Spotted by divers and shared online, this tiny marine creature puzzled scientists before earning a name of its own.

Scientists from the University of California, Santa Cruz have just taken a huge step in the long history of lab-cultured brains.

A new project allowed AI chatbots to interrupt, stay silent or speak up the way humans do in conversation, and it made them smarter and more accurate.

MIT researchers have uncovered chemical evidence suggesting that ancient sea sponges were among the first animals on Earth, offering new insights into the origins of life.

A new NASA analysis concludes that it is "reasonable to hypothesize" that living things could have formed the odd organic molecules discovered on Mars.

Some creatures can dramatically alter their internal temperature — a strategy called heterothermy — and outlast storms, floods and predators.

Genetic analysis of 5,500-year-old remains from a Swedish burial site has uncovered surprising family connections, revealing the important role of extended kinship in prehistoric communities.

Scientists placed bacteria and fungi on a meteorite in space. The metals they managed to release may reshape deep space missions.

A vast geoid anomaly beneath Antarctica is revealing secrets from deep inside Earth.

A statistical analysis of a series of signs carved into artifacts from around 40,000 years ago suggests humans developed proto-writing in the Stone Age.

Six hundred million years ago, a tiny sea creature with a single eye on its forehead drifted through ancient oceans. It lost its vision, then rewrote the future of sight.
