Three ancient Maya cities have been discovered by archaeologists in Guatemala.

A new study finds the genetic backgrounds of people in the U.S. are "highly complex" and may differ from their self-defined racial or ethnic groups.

Earth lost contact with the private Japanese spacecraft "Resilience" during an attempted moon landing on Thursday. The lander was carrying what would have been the first European-built rover to explore the moon.

A new study shows that mice, like humans, can experience a sense of embodiment toward an artificial limb--similar to the famous rubber-hand illusion. When their real limb was hidden and both real and fake limbs were brus...

Scientists have introduced a new laboratory model that could help them study how artificial limbs can be better designed.

Taurine supplements have previously been found to extend the lifespan of monkeys and mice, but a new study in humans shows that the amino acid doesn't decline with age

Metallic nanoparticles injected into the retina partly restored vision in blind mice and could work as a treatment for conditions that damage light-sensitive cells in the eye

Brain-inspired computers could boost AI efficiency--a tantalizing prospect as the industry's energy bills mount. The post Sandia Fires Up a Brain-Like Supercomputer That Can Simulate 180 Million Neurons appeared first on...

A pair of new studies has revealed that the hellish skies of exoplanet WASP-121b contain silicon monoxide gas, which has never been found in any planetary atmosphere to date.

Quantum materials exhibit remarkable emergent properties when they are excited by external sources. However, these excited states decay rapidly once the excitation is removed, limiting their practical applications.

In rare cases where users are vulnerable to psychological manipulation, chatbots consistently learn the best ways to exploit them, a new study has revealed.

For reasons still unknown, Earth's energy imbalance is rising much faster than models can account for. Now, scientists are calling for long-term investment in monitoring capability, so that they can make informed predict...

Researchers have published the demonstration of a fully-integrated single-chip microwave photonics system, combining optical and microwave signal processing on a single silicon chip.

Two brain regions seem to work together to determine whether we are seeing something real, or merely a product of our imaginations - and understanding them further may help treat visual hallucinations

Thousands of tiny nematode worms can join up to form tentacle-like towers that can straddle large gaps or hitch rides on larger animals

A new study shows that AI can create internet memes rated as funny and shareable as those made by humans--but the best jokes still come from people. Researchers compared memes made by humans, AI, and human-AI teams, usin...

The bizarre behavior had previously been observed in experimental settings and was thought to be a competitive attempt to escape from the rest of the group. But new research suggests a more cooperative motivation.

Populations of dopamine neurons don't simply signal reward prediction errors--they encode rich maps of possible future outcomes, including when and how much a reward might be. This diverse, adaptable neural code mirrors ...

A new study reveals that strong family relationships and parental engagement are linked to longer, healthier sleep in children aged 9 to 11. Eating dinner together, planning the next day, and participating in community a...

Researchers have developed an AI-based diagnostic tool that uses smartphone video and cloud computing to detect nystagmus--a key symptom of balance and neurological disorders. Unlike traditional methods like videonystagm...

These 10 incredible things can be easily observed at home, in the lab or in the classroom.

FDA-approved HIV drugs targeting reverse transcriptase (RT) may reduce Alzheimer's risk by blocking similar enzymatic activity in the aging brain. Scientists discovered unexpected RT activity in neurons of healthy and Al...
