A single dose reversed autism-like symptoms in adult mice within hours
Even mild inflammation during pregnancy led mouse offspring to develop persistent brain overactivity, sensory sensitivity, repetitive behaviors, and increased seizure risk. Remarkably, one dose of rapamycin improved nearly all of these problems within …
Superagers keep youthful memories but their DNA does not explain why
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,…
Scientists put the “recycling is a distraction” claim to the test
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…
The Universe can outrun light without breaking Einstein’s rules
Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they emitted when they were much closer. Eventually, accelerating expansion will push nearly every galaxy beyond our Local Group out of si…
Coffee may help shield the liver from fat, scarring, and cancer
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. Benefi…
Oral GLP-1 drugs may quiet the brain’s food craving circuit
Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit. The finding could open new avenues for understanding food cravings and potentially treating substance us…
A daily fiber supplement reduced knee arthritis pain and improved strength
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 ea…
Venus may be tearing itself apart from within
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 …
Scientists discover the Sun contains 55% more silver than expected
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 techniq…
