A single dose reversed autism-like symptoms in adult mice within hours
9+ hour, 43+ min ago (828+ words) A UCLA Health study in mice has found that inflammation during pregnancy can produce lasting autism-like changes in offspring. The researchers also discovered that many of the resulting brain and behavioral effects could be improved rapidly in adulthood, although only…...
Superagers keep youthful memories but their DNA does not explain why
10+ hour, 11+ min ago (91+ words) Scientists expected SuperAgers might simply inherit fewer Alzheimer’s-related risks, but their genes looked much like those of typical older adults. Their extraordinary memories may instead come from still-unknown protective forces involving the brain, body, lifestyle, and environment....
Scientists put the “recycling is a distraction” claim to the test
10+ hour, 52+ min ago (236+ words) Recycling, greener diets, and other personal climate choices do not seem to distract people from supporting major environmental reforms. A four-year study of nearly 2,800 Australians found that these habits neither increased nor reduced later political engagement....
The Universe can outrun light without breaking Einstein’s rules
11+ hour, 36+ min ago (703+ words) This means that when a telescope captures the light from a distant galaxy, the image does not reveal where that galaxy is today. It shows the galaxy as it appeared when the light began its journey. To estimate its present…...
Coffee may help shield the liver from fat, scarring, and cancer
12+ hour, 26+ min ago (337+ words) A major long-term study linked coffee consumption with lower risks of cirrhosis, liver cancer, and death from liver disease. Coffee drinkers also showed healthier liver scans and blood protein patterns, with less fat, inflammation, and scarring. Benefits appeared even at…...
Oral GLP-1 drugs may quiet the brain’s food craving circuit
13+ hour, 19+ min ago (695+ words) Popular weight-loss and diabetes medications such as semaglutide and Ozempic belong to a broader group known as GLP-1 drugs. A study funded by the National Institutes of Health (NIH) has now identified a previously unrecognized way that some newer oral…...
A daily fiber supplement reduced knee arthritis pain and improved strength
14+ hour, 52+ min ago (353+ words) A prebiotic fiber supplement reduced knee osteoarthritis pain while also improving grip strength and pain sensitivity in a six-week trial. The results hint at a fascinating gut-muscle-pain connection and suggest that a simple daily supplement may be easier to maintain…...
Venus may be tearing itself apart from within
21+ hour, 34+ min ago (385+ words) Scientists have uncovered new evidence that Venus may still be tearing itself apart from within. Advanced 3D simulations indicate that some of the planet's giant rift valleys formed relatively recently and could still be expanding. The results suggest Venus…...
Scientists discover the Sun contains 55% more silver than expected
22+ hour, 58+ min ago (296+ words) A new analysis suggests the Sun holds far more silver than earlier estimates indicated. More advanced models of the solar atmosphere raised the calculated amount by 55 percent, bringing it into much closer agreement with ancient meteorites. The technique may also…...
AI helps Stanford scientists discover “natural Ozempic” without the usual side effects
1+ day, 11+ hour ago (1243+ words) Stanford Medicine researchers have identified a naturally occurring molecule that may suppress appetite and reduce body weight in a way that resembles semaglutide, the active ingredient in Ozempic. In animal studies, the molecule also appeared to avoid several problems associated…...
