Phys.org / JWST may solve a 20-year mystery behind a rule-breaking gamma-ray burst
Astronomers may have finally solved the mystery behind a nearly two-decade-old cosmic explosion that seemed to break the rules of physics. The energy output of a powerful gamma-ray burst, GRB 061201, discovered in 2006, did ...
Medical Xpress / Gut bacteria linked to key brain chemicals in first-of-its-kind human study
The neuroactive potential of bacteria living in the human gut is associated with levels of key chemicals in the brain, according to a new study published in Molecular Psychiatry. The research team from the University of Surrey ...
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 / 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 / Iron helped scientists trace Earth's oxygen. Now it's telling a bigger story
For decades, scientists have studied iron preserved in ancient rocks to reconstruct how Earth's oceans and atmosphere became rich in oxygen. A new study suggests iron has recorded other major transformations too.
Phys.org / Newly discovered 1666 manuscript may trace four-lens telescope experiments to Galileo
A potentially history-altering finding by a University of Limerick researcher may provide the most detailed technical analysis of a telescope demonstrably made by the famous astronomer and scientist Galileo Galilei.
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.
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 / '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 ...
Phys.org / JWST reveals likely Type II supernova from when universe was only 2 billion years old
Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195—so far away that its light has been traveling ...
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 ...
