Scientists revive a powerful antibiotic that superbugs had defeated

Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a bacterial enzyme linked to resistance. The combination restored the antibiotic’s ability to kill drug-resistant E. faecium, raising hopes that similar chemical helpers could rescue other failing medicines.

New cancer strategy could stop tumors before resistance takes hold

Researchers are applying evolutionary theory to cancer by changing treatments before tumors have time to develop resistance. Mathematical models suggest that rapid, carefully timed switches between multiple therapies could improve cure rates.

Magic mushrooms may reshape the brain long after the trip ends

A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in flexible, varied brain activity also reported more personal insight and later improvements in well-being. The findings suggest that the psychedelic experience itself may help people break free from entrenched patterns of thinking.

New programmable photonic chip can control how fast light moves

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical. A single chip could eventually perform several tasks that currently require separate devices, potentially reducing energy use, cost, and complexity in AI servers and data centers.

Coffee may protect your heart but energy drinks could harm it

For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally safe and may even be linked to lower risks of heart disease, stroke, heart failure, and Type 2 diabetes. But the source matters: highly concentrated energy drinks and shots can sharply raise blood pressure and trigger irregular heart rhythms.

Watching too much TV in midlife may shrink the brain

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along with more signs of damage in the brain’s white matter. Surprisingly, sitting itself did not appear to be the main issue, since people who spent long hours seated at mentally engaging jobs often showed healthier brain patterns.
