A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-t…

A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have regularly…

Using the Keck Observatory, astronomers measured the spins of dozens of giant planets and brown dwarfs orbiting distant stars. They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about mass …

Learning a musical instrument later in life may help keep the brain younger for longer. In a four-year study, older adults who continued practicing maintained their memory performance and showed less age-related brain shrinkage than those who quit. The…

A child psychologist says grandparents are more important than ever as youth mental health challenges continue to rise. He argues that children need supportive relationships, meaningful conversations, and a sense of purpose—not just pressure to achieve…

Scientists have uncovered a surprising new genetic cause of a rare movement disorder after analyzing nearly 3,000 patients with conditions affecting coordination and muscle control. The team identified mutations in a gene called CD99L2, previously link…

A bold claim that the universe’s accelerating expansion was an illusion has been put to the test—and failed. Researchers found that the study behind the controversy made key mistakes when analyzing supernova data. After revisiting the evidence, astrono…

A new experimental vaccine developed by Scripps Research could offer a powerful new way to prevent fentanyl overdoses by stopping the drug before it reaches the brain. Rather than targeting only fentanyl itself, the vaccine trains the immune system to …
