Scientists finally see how nature moves energy so efficiently

Researchers have captured key steps in a chemical reaction that helps nature transfer energy with remarkable efficiency. Ultrafast X-rays revealed how changes involving electrons and protons are closely linked to the rearrangement of surrounding water molecules. Because similar r

Vagus Nerve Stimulation Could Help New Skills Stick

Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect was linked to rhythmic changes in brain blood vessels, hinting that body-to-brain

Powerful simulations reveal how the first stars changed the universe

Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron. The MEGATRON project could bridge JWST observations of the earliest galaxies with chemical clues preserved in ancient stars today.

Electrons slow to a crawl in a strange new quantum state

Scientists at the University of Chicago have uncovered a surprising quantum state in the layered magnetic material Fe5GeTe2, where huge numbers of electrons move together unusually slowly while remaining quantum coherent. The behavior contradicts existing theoretical predictions

This diet may slow brain aging by 2.5 years

People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss over time, with the strongest differences equivalent to about 2.5 years of delayed brain aging. Berries and poultry were linked with healthier brain changes, while sweets and fr

A record-breaking X-ray flash may reveal the birth of a magnetar

Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way to find these extreme cosmic m

Brain scans reveal which disorders are linked to faster brain aging

A massive MRI study found that Alzheimer’s disease, mild cognitive impairment, psychiatric disorders, and addiction are associated with distinct patterns of accelerated brain aging. The strongest effects appeared in Alzheimer’s and mild cognitive impairment, while ADHD and autism
