Sugar damage in the body was thought to be irreversible. But the new enzyme made 75-year-old tissue look chemically like a 30-year-old's. The post Designer Enzyme Strips Decades of Rust From Aging Human Tissue appear...

Researchers discovered that the youth-associated protein TIMP2 restores healthy immune function in the aging brain by rejuvenating microglia.

Basic biology courses teach that cells contain organelles-such as the nucleus, mitochondria and Golgi apparatus-set apart by lipid membranes to get things done. Recent cell biology research has revealed another organizat...

A new analysis of skulls from a 14th-century battle in Sweden reveals a spiked club inflicted the death blow.

A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of ...

To cut the cost of key stage 2 assessments, a UK government project proposes to use scripts generated by ChatGPT instead of real children's writing as examples supplied to moderators who check that grades are awarded...

A drug made up of THC, the main psychoactive component of cannabis, reduced the severity and incidence of nightmares in people with PTSD

In the Leiden Declaration, mathematicians issued a treatise on how AI challenges their field. Others must do the same. The post Biology Needs an AI Declaration appeared first on SingularityHub.

A strange-sounding treatment may offer relief for people with a little-understood type of excessive belching.

The use of explosives to kill fish is widespread across the tropics, and acoustic monitoring in an Indonesian archipelago detected more than 3500 explosions in 483 days

Almost three-quarters of England is now in drought conditions, resulting in restrictions on water use in many areas and severe wildfires - here's how it's affecting farming, wildlife and trees

New research suggests some of Brazil's most important aquifers, located beneath major agricultural regions, aren't being replenished. What does this mean for the country's water supply and food exports?

Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the blood begin entering the...

A reconstruction of East Africa's environment 1.75 million years ago suggests wildfires spiked during wetter times, which may have influenced human evolution

A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate autonomously inside quantum...

Simply choosing the stairs could have surprisingly big benefits for your heart and longevity. A large analysis involving more than 480,000 people found that regular stair climbers were 39% less likely to die from cardiov...

We've perhaps been conditioned to not ask too many questions, in case it comes across as rude or prying. But columnist David Robson argues that asking people open-ended questions benefits our wellbeing, and doesn'...

A surprising stress-related signal may help the brain repair itself after injury. Researchers found that myelin-producing precursor cells rapidly release the stress hormone CRH near damaged brain tissue, helping control ...

Women who used estrogen-only hormone therapy later in life were less likely to develop dementia and showed fewer signs of Alzheimers disease in their brains, according to a large study of more than 21,000 participants. H...

Researchers have found strong evidence that original collagen can survive inside dinosaur fossils for tens of millions of years, overturning a long-standing assumption about fossilization. The discovery could unlock hidd...

Scientists have found that the AMOC may be far more vulnerable to rapid warming than to temperature alone. When warming happens slowly, the ocean can adapt, but at faster rates similar to todays, the massive Atlantic cir...

JWST has uncovered surprising clues that Neptunes strange inner moons may be the wreckage of an ancient cosmic catastrophe. Researchers detected clay-like minerals on Larissa, Galatea, and Neptunes rings that form in the...
