Medical Xpress / Healthy aging shaped by more varied biology than previously thought
Molecular changes in aging are far more unique than previously thought, meaning two healthy individuals of identical age can experience significantly different aging journeys.
Medical Xpress / Experimental brain implants are on the rise. What happens after the trials are over?
In 2024, Elon Musk's Neuralink put its first brain implant into a human amid doubt from scientists and allegations of animal cruelty.
Phys.org / How hibernating squirrels retain sense of touch in the cold
For most mammals, cold suppresses neural activity and diminishes the sense of touch. But the thirteen-lined ground squirrel can detect touch in conditions as low as 4°C (39°F), about as cold as the inside of a refrigerator, ...
Medical Xpress / Immune cells may have a biological memory that makes weight loss harder after obesity
According to the World Health Organization, one in eight people lives with obesity. Yet despite numerous health education programs, books, articles and treatments, many individuals still struggle to lose weight once they ...
Phys.org / Quantum-optical spin glass could improve how AI remembers and learns
A new study has demonstrated that it is possible to make a network of atoms and photons that could improve how artificial intelligence stores and recalls memories. This network, called a quantum-optical spin glass, works ...
Phys.org / Mammalian genes can combine to make previously unknown mRNAs and proteins
For decades, scientists have understood that each of the roughly 20,000 genes in the human body carries instructions for a single kind of protein. Now, researchers at Harvard Medical School have discovered that instructions ...
Phys.org / New 'devil flower' species discovered in Thai national park
Researchers have described a new species of leafless flowering plant found on the forest floor of a national park in western Thailand, and its otherworldly appearance has earned it a fittingly dramatic name: Thismia daemona, ...
Phys.org / How an unassuming wildflower thrives in salt-laden air that kills other plants
On the windswept coasts of Oregon and California lives an unassuming little plant that can withstand salty blasts that kill its inland counterparts. It's called the yellow monkeyflower. Now, researchers are beginning to understand ...
Medical Xpress / Over 90% of people carry this virus—and it can cause more than chickenpox and shingles
New research published in Nature Reviews Disease Primers is shedding light on the surprisingly broad range of neurological and systemic diseases that can be caused by varicella zoster virus (VZV), the virus that causes chickenpox ...
Phys.org / Hubble tracks new decagon encircling Saturn's south pole
Recent observations with NASA's Hubble Space Telescope have revealed a giant, evolving, 10-sided atmospheric wave encircling Saturn's south pole. This discovery marks the first time a large, regular-sided jet pattern has ...
Phys.org / 'Soft crosslinking' strategy makes brittle, glassy plastics tougher
Glassy polymers are those whose chains become immobilized below their glass transition temperature. The immobilized chains make them hard and stiff but also brittle, causing them to fracture when stretched. One promising ...
Medical Xpress / 3D atomic-level snapshots reveal ketamine binds to human opioid receptors
Ketamine, a drug approved for medical use in 1970 as a short-acting anesthetic, including during the Vietnam War for battlefield surgery, is still a pharmacological mystery. For a long time, scientists knew that ketamine, ...
