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.

A study at Bonn University found that the Australian jumping spider undergoes two stages of sleep, including a stage characterized by eye movements and muscle twitches, similar to REM sleep in humans. The findings may shed light on the evolution of sleep in the animal world.
A dinosaur the size of a turkey, with a parrot-like beak and no teeth, lived about 66 million years ago and fed on fruit and soft plants. The fossils uncovered in the United States indicate unique adaptations that allowed it to chew and mash its food – broadening what is known about dinosaur diets.
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.
