2. oktober 2025 Rapportert av AI

A new study suggests that the evolution of menopause plays a key role in women's longer lifespans compared to men. Researchers propose that post-reproductive life in women allows investment in grandchildren, contrasting with men's continued reproduction. This theory draws on data from hunter-gatherer societies and modern populations.

Images show rifampicin's effects on E. coli bacteria

Scientists have captured the first detailed images revealing how the common antibiotic rifampicin disrupts E. coli bacteria at a molecular level. Using advanced cryo-electron tomography, researchers visualized the drug binding to bacterial machinery, halting growth. The findings, published in Nature, offer new insights into antibiotic mechanisms.
