Brain food fight: Rutgers maps the hidden switch that turns cravings on and off

Scientists know the stomach talks to the brain, but two new studies from Rutgers Health researchers suggest the conversation is really a tug-of-war, with one side urging another bite, the other signaling “enough.” Together, the papers in Nature Metabolism and Nature Communications trace the first complementary wiring diagram of hunger…

Scientists just solved a 40-year-old mystery about quasicrystals

A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of atoms, according to a study from the University of Michigan. The findings come from the first quantum-mechanical simulations of quasicrystals — a type of solid that scientists once thought couldn’t exist.…

Your breath is one of a kind. A study published June 12 in the Cell Press journal Current Biology demonstrated that scientists can identify individuals based solely on their breathing patterns with 96.8% accuracy. These nasal respiratory “fingerprints” also offer insights into physical and mental health. The research stemmed from…

The 10,000-mile march through fire that made dinosaurs possible

The forerunners of dinosaurs and crocodiles in the Triassic period were able to migrate across areas of the ancient world deemed completely inhospitable to life, new research suggests. In a paper published in Nature Ecology and Evolution on June 11, researchers from the University of Birmingham and University of Bristol have used…

Sleep-in science: How 2 extra weekend hours can calm teen anxiety

A new study to be presented at the SLEEP 2025 annual meeting found that teens who get moderate — but not excessive — catch-up sleep on weekends have fewer symptoms of anxiety. Results show that teens who got up to two more hours of sleep on weekends than on weekdays…

Running rewires your brain cells—igniting memory-saving genes against alzheimer’s

Using advanced single-nuclei RNA sequencing (snRNA-seq) and a widely used preclinical model for Alzheimer’s disease, researchers from Mass General Brigham and collaborators at SUNY Upstate Medical University have identified specific brain cell types that responded most to exercise. These findings, which were validated in samples from people, shed light on…

New MIT study reveals how biofilms help stop microplastic build-up

The accumulation of microplastics in the environment, and within our bodies, is an increasingly worrisome issue. But predicting where these ubiquitous particles will accumulate, and therefore where remediation efforts should be focused, has been difficult because of the many factors that contribute to their dispersal and deposition. New research from…

Rivers are exhaling ancient carbon — and climate math just changed

A new study has revealed for the first time that ancient carbon, stored in landscapes for thousands of years or more, can find its way back to the atmosphere as CO2 released from the surfaces of rivers. The findings, led by scientists at the University of Bristol and the cover…

NASA’s Webb telescope reveals monster star clumps in galactic wreckage

Astronomers have surveyed massive, dense star factories, unlike any found in the Milky Way, in a large number of galaxies across the local universe. The findings provide a rare glimpse into processes shaping galaxies in the very early universe and possibly the Milky Way a few billion years from now.…

Beyond Ozempic: New weight loss drug rivals surgery

Weight loss drugs like Ozempic and Wegovy are used by over 15 million adults in the U.S., or 4.5% of the population. Despite their effectiveness, they have drawbacks. Their effect may not last after discontinuing use, and side effects including osteoporosis and muscle loss have raised concerns about long-term harms.…

Brain-computer interface restores real-time speech in als patient

Researchers at the University of California, Davis, have developed an investigational brain-computer interface that holds promise for restoring the voices of people who have lost the ability to speak due to neurological conditions. In a new study published in the scientific journal Nature, the researchers demonstrate how this new technology…

Scientists warn of bat virus just one mutation from infecting humans

A group of bat viruses closely related to the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) could be one small mutation away from being capable of spilling over into human populations and potentially causing the next pandemic. A recent study published in the journal Nature Communicationsexamined an understudied group of…

Atom-thin tech replaces silicon in the world’s first 2D computer

UNIVERSITY PARK, Pa. — Silicon is king in the semiconductor technology that underpins smartphones, computers, electric vehicles and more, but its crown may be slipping according to a team led by researchers at Penn State. In a world first, they used two-dimensional (2D) materials, which are only an atom thick…

Cleaner fish: Tiny healers or hidden spreaders in coral reef ecosystems?

Where do you go when you’re a fish and you need a skincare treatment? Coral reefs contain natural “beauty salons,” lively social hubs of activity where fish “clients” swim up and wait to be serviced by smaller fish cleaners. The little cleaners dart under and around their much bigger clients…

Smart nanoparticles launch genetic attack on lung cancer and cystic fibrosis

Scientists have made a key breakthrough for treating respiratory diseases by developing a new drug delivery system that transports genetic therapies directly to the lungs, opening promising possibilities for patients with conditions like lung cancer and cystic fibrosis. The research, led by Gaurav Sahay of Oregon State University’s College of…

Something more toxic than gators is hiding in the swamps

New research from the University of Georgia’s Odum School of Ecology and Marine Extension and Georgia Sea Grant suggests there may be elevated levels of mercury in Georgia and South Carolina waters.
