Scientists discover a surprising brain benefit of eating peanuts every day

A surprising new study suggests that eating peanuts every day could help support brain health and memory in older adults. Researchers found that consuming about two servings of unsalted, skin-roasted peanuts daily for 16 weeks improved insulin responsiveness in brain regions important for memory, a function that often weakens with age and has been linked to Alzheimer's disease.

Scientists shrink Archimedes’ screw to the size of a single molecule

Scientists have built a groundbreaking molecular motor that spins in either direction using electricity, inspired by a machine invented more than 2,000 years ago. Even more remarkably, its rotation can boost electrical conductivity by up to 100 times, potentially transforming the future of molecular electronics.

The Great Barrier Reef's most notorious coral killer may actually be helping it

Crown-of-thorns starfish are notorious for devouring coral reefs, but surprising new research reveals these spiny predators may actually help reefs thrive when their populations are kept in check. Scientists studying Australia's Great Barrier Reef discovered that nearly 75% of observed starfish feeding events left behind living coral tissue, rather than destroying entire colonies. By feeding on fast-growing, dominant corals, the starfish create opportunities for slower-growing species to survive

Drinking tea may help protect your heart, but there’s a surprising catch

A massive study of nearly 486,000 adults found that regularly drinking tea was associated with an 11% lower risk of heart and blood vessel diseases. The lowest risk was linked to drinking roughly six to eight cups per day, with black tea showing more consistent benefits than green tea.

Scientists use sound waves to deliver a new attack on deadly brain cancer

Scientists at the University of Virginia have developed a promising new strategy to fight glioblastoma, one of the deadliest and most difficult-to-treat forms of brain cancer. Their experimental approach combines focused ultrasound, tiny nanoparticles, and genetic molecules called microRNAs to attack multiple cancer-driving genes simultaneously.

Ancient ape fossil in Egypt could rewrite the story of human origins

A 17- to 18-million-year-old ape fossil discovered in Egypt is challenging long-held beliefs about where the ancestors of humans and other modern apes first evolved. Scientists now suspect that North Africa and the Middle East, rather than East Africa, may have been the cradle of modern ape evolution.
