Researchers have identified how CBD interacts with cannabinoid receptors to mitigate the negative effects of THC, the psychoactive component of cannabis. Unlike THC, which fully activates the receptor and causes side eff...

Multiferroic materials, in which electric and magnetic properties are combined in promising ways, will be the heart of new solutions for data storage, data transmission, and quantum computers. Meanwhile, understanding th...

Researchers have discovered that positive emotions enhance perceptual memories during sleep, particularly in the non-REM stage. Using mice, they found that memories linked to rewarding experiences lasted longer than neut...

When humans kick swim through water, vortices form around their legs, generating the force that propels them forward. However, the mechanisms underlying variations in the structure of these vortices with swimming speed r...

The sounds that make up humpback whale songs follow some of the same statistical rules seen in human languages, which may be because of how they are learned

Scientists are studying the vaginal microbiome in populations all around the world to see how it might differ in different people and in health and disease.

A 2,000-year-old Herculaneum scroll buried by the eruption of Mount Vesuvius is filled with lost words that scholars can now decipher thanks to AI and a particle accelerator.

Jupiter and Mars will appear to make ultraclose approaches to the moon on two nights this week. Here's how to get the best view, starting tonight.

AI transformational impact is well under way. But as AI technologies develop, so too does their power consumption. Further advancements will require AI chips that can process AI calculations with high energy efficiency. ...

A new virus that is related to the deadly Nipah and Hendra viruses has been detected in shrews in the U.S. However, scientists say there is currently "no evidence" that it has infected humans and the risk of it doing so ...

Researchers at Tohoku University have achieved a significant advancement in opto-magnetic technology, observing an opto-magnetic torque approximately five times more efficient than in conventional magnets. This breakthro...

Genetic analysis suggests a form of mosquito found in urban subway systems evolved in the Middle East thousands of years ago

If you have the patience to repeatedly switch an egg between a hot and a colder pan, you'll be rewarded with an amazing taste and texture, say physicists

Archaeologists discovered ancient Roman inscriptions and a 1,900-year-old coin wedged between rock formations while exploring a cave called the Cova de les Dones in eastern Spain.

How does cold milk disperse when it is dripped into hot coffee? Even the fastest supercomputers are unable to perform the necessary calculations with high precision because the underlying quantum physical processes are e...

New 3D maps of the Greenland Ice Sheet show how huge cracks in the ice that accelerate melting expanded between 2016 and 2021.

A lidar scanner has a resolution so high it can image ridges and indentations only 1 millimetre deep on objects hundreds of metres away - and capture objects as distant as 1 kilometre

Researchers have designed a single-photon time-of-flight LiDAR system that can acquire a high-resolution 3D image of an object or scene up to 1 kilometer away. The new system could help enhance security, monitoring, and ...

A new study has greatly expanded the number of gene variants thought to be tied to bipolar disorder.

Scientists using the Hubble Space Telescope have spotted a record-smashing galaxy wrapped in 9 rings of stars -- along with the dwarf galaxy that violently plunged through its center.

More than a quarter million beads found in a tomb with female skeletons were used to decorate the women's ceremonial dresses, suggesting they were powerful leaders five millennia ago.

February's full Snow Moon will have a royal companion as it rises alongside Regulus, a star nicknamed "Heart of the Lion", before Valentine's Day.
