Medical Xpress / How do GLP-1 agonists affect gene expression?
GLP-1s are building a reputation as "wonder drugs." First characterized for their ability to improve insulin release and treat diabetes, the drugs were later found to promote weight loss and improve cardiovascular health. ...
Medical Xpress / Empathy's roots in parenting? Study in mice reveals brain circuits behind why we comfort others
Humans and animals share a remarkable capacity to sense when others are in distress and respond with comforting behavior. But the motivation for doing so, and why it sometimes breaks down, has been poorly understood. UCLA ...
Phys.org / Large area MoS₂ reduces energy loss in magnetic memory films
Scientists at the University of Manchester have discovered that placing magnetic films on atomically thin molybdenum disulfide (MoS₂) fundamentally changes how they lose energy, a finding that could bring 2D‑material ...
Phys.org / Neutrons reveal magnetic signatures of chiral phonons
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...
Phys.org / Meet 'Tous'—an entirely new genus of mammal
Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people picture biodiversity, ...
Medical Xpress / Open-source, privacy-focused platform aims to help researchers examine how digital interactions influence health
Numerous sensors allow smartphones to silently witness everything we do, says Ian Kim, a postdoctoral fellow in psychology at Stanford University. They count each smartphone owner's steps, measure their sleep, record where ...
Medical Xpress / Researchers detect complex emotions by combining multiple optical signals
Researchers have developed a new way to recognize human emotions by combining fiber-based physiological signals with thermal images of the face. The portable emotional recognition system could eventually be used to support ...
Phys.org / Binary star population of open cluster NGC 2158 explored with Hubble
Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster known as NGC 2158. Results of the study, published Feb. 25 on the arXiv pre-print server, provide essential ...
Phys.org / New LVK catalog adds 128 gravitational-wave candidates, more than doubling detections
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...
Medical Xpress / New study shows how sickle cell affects brain function
Sickle cell disease is often thought of solely as a blood disorder, but new research from the Wood Neuro Research Group provides measurable evidence that it can reshape how brain networks function. Previous neuroimaging studies ...
Phys.org / Superfluids emerge in 2D moiré crystal formed from time, study predicts
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating ...
Phys.org / A new 'molecular switch' for inborn immunity identified
Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which ...
