Using laser light instead of traditional mechanics, researchers have built micro-gears that can spin, shift direction, and even power tiny machines. These breakthroughs could soon lead to revolutionary medical tools working at the scale of cells.

Scientists at the University of Geneva have created the first detailed catalogue of gut bacteria at the subspecies level, unlocking powerful new ways to detect colorectal cancer. By applying machine learning to stool samples, they achieved a 90% ...

Rogue DNA rings known as ecDNA may hold the key to cracking glioblastoma's deadly resilience. Emerging before tumors even form, they could offer scientists a crucial early-warning system and a chance to intervene before the disease becomes ...

Scientists in Zurich have shown that stem cell transplants can reverse stroke damage by regenerating neurons, restoring motor functions, and even repairing blood vessels. The breakthrough not only healed mice with stroke-related impairments but also ...

Scientists have uncovered how the brain reroutes its communication pathways depending on whether it's processing something new or recalling the familiar. By fine-tuning the balance between different inhibitory circuits, the brain flexibly shifts ...

Switching clocks twice a year disrupts circadian rhythms in ways that harm health. Stanford scientists found permanent standard time would reduce obesity and stroke rates nationwide, making it the strongest option over permanent daylight saving time ...

Some people taking Ozempic, Wegovy, or Mounjaro notice that food suddenly tastes sweeter or saltier, and this subtle shift in flavor perception appears tied to reduced appetite and stronger feelings of fullness. In a study of more than 400 patients, ...

People taking semaglutide report far fewer obsessive thoughts about food, with cravings dropping sharply and mental health improving. This new research hints the drug may offer freedom from the constant distraction of food noise.

Preschoolers with ADHD are often given medication right after diagnosis, against medical guidelines that recommend starting with behavioral therapy. Limited access to therapy and physician pressures drive early prescribing, despite risks and reduced ...

Scientists at UC San Diego have identified a new drug, ION224, that could transform the treatment of MASH, a dangerous form of fatty liver disease tied to obesity and diabetes. By blocking a key liver enzyme, the drug reduces fat and inflammation, .. ...
