Sleeve gastrectomy, common weight-loss surgery, lowers women's tolerance to alcohol

A study found that women who underwent sleeve gastrectomy may need to limit their alcohol consumption due to faster absorption rates. The surgery speeds up the transfer of alcohol into the bloodstream, leading to higher blood alcohol levels and increased risk of binge drinking and associated health issues.

Astronomers reveal nearby stars that are among the oldest in our galaxy

A team of astronomers from Georgia State University has discovered two old binary stars and identified 29 new old star candidates using a technique called astrometry. The study focused on subdwarf stars, which are cooler and older than the sun, and used their motion across the sky to determine their age.

Protein intentionally terminates own synthesis by destabilizing synthesis machinery -- the ribosome

Researchers found that proteins with specific sequences can trigger the degradation of their own synthetic ribosomes, leading to aborted translation. However, living organisms also possess a mechanism to counteract this phenomenon, allowing for precise regulation of protein expression in response to environmental changes.
