Screen use at certain stages of childhood was linked to subtle differences in later academic and cognitive performance. Screens are now a routine part of life for many young children, but their possible effects on later learning remain uncertain. A study that tracked children from age 1 through age 8 found that greater viewing time, […]
Viagra May Block a Hidden Pathway Cancer Cells Need To Spread
A familiar drug may influence an unexpected cellular pathway that controls how cholesterol moves inside cancer cells. A medication now closely associated with erectile dysfunction began as a treatment for high blood pressure and chest pain caused by limited blood flow to the heart. Three decades later, sildenafil, the active ingredient in Viagra, may have […]
Underwater Drones Find “Dead” Coral Reefs Teeming With Life
Researchers used sonar and underwater imaging systems to locate a mesophotic coral garden that scientists in the 1960s had assumed was dead. More than 50 meters beneath the waters off Benin, cameras revealed a coral community that scientists had once presumed dead. Fishing surveys conducted in the 1960s had identified what appeared to be a […]

Scientists Discover the Brain Is Not Always Ready To Make Memories
Your brain may have brief windows when it is primed to transform a passing moment into a lasting memory. Researchers at the University of Tübingen found that natural shifts in alertness can briefly change the hippocampus, making its memory circuits more receptive to new information. The findings suggest that memory formation depends not only on […]
Earth’s First Complex Organisms May Hold Clues to Life Beyond Our Planet
Earth’s oldest eukaryotic fossils may illuminate both the rise of complex life and the search for life elsewhere. Searching for life on Mars or the icy moons Europa and Enceladus may attract more attention than studying how life developed on Earth. Yet tracing the appearance of the first eukaryotes on our planet is just as […]

Dark Matter’s Secret Force Could Reshape Our Understanding of the Universe
Why giving dark matter an additional attractive force does not necessarily produce “clumpier matter.” Dark matter shapes galaxies and the large structure of the Universe through gravity, yet no one knows whether gravity is its only influence. Dark matter particles might also pull on one another through a hidden force that ordinary matter cannot feel. […]
