Life's story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these rare genes, researchers can investigate how early ...

A large U.S. study suggests that not getting enough lycopene--the antioxidant that gives tomatoes their red color--may seriously raise the risk of severe gum disease in older adults. Researchers found that seniors with adequate lycopene intake had .. ...

A long-standing mystery in spintronics has just been shaken up. A strange electrical effect called unusual magnetoresistance shows up almost everywhere scientists look--even in systems where the leading explanation, spin Hall magnetoresistance, ...

A sweeping new review of ADHD treatments--drawing on more than 200 meta-analyses--cuts through years of mixed messaging and hype. To make sense of it all, researchers have launched an interactive, public website that lets people with ADHD and ...

Researchers at the University of Michigan have created an AI system that can interpret brain MRI scans in just seconds, accurately identifying a wide range of neurological conditions and determining which cases need urgent care. Trained on hundreds . ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying on any external clock. By tracking subtle changes . ...

Satellite imagery reveals how the 2026 Winter Olympics are spread across northern Italy, from alpine valleys to historic cities. Events are hosted in mountain resorts, while Milan and Verona frame the Games with opening and closing ceremonies. The .. ...

We don't experience the world through neat, separate senses--everything blends together. Smell, touch, sound, sight, and balance constantly influence one another, shaping how food tastes, objects feel, and even how heavy our bodies seem. Scientists . ...

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots causing messy electrical signals turn out to be .. ...

A long-term study found that women who closely followed a Mediterranean diet had a much lower risk of stroke. The strongest benefits were seen in women who ate more plant-based foods, fish, and olive oil while cutting back on red meat and saturated . ...
