Scientists tracking Earth's water from space discovered that El Niño and La Niña are synchronizing floods and droughts across continents. When these climate cycles intensify, far-apart regions can become unusually wet or dangerously dry at the same ...

Scientists at Tufts have found a way to turn common glucose into a rare sugar that tastes almost exactly like table sugar--but with far fewer downsides. Using engineered bacteria as microscopic factories, the team can now produce tagatose efficiently ...

Some antibiotics stop bacteria from growing without actually killing them, allowing infections to return later. Scientists at the University of Basel created a new test that tracks individual bacteria to see which drugs truly eliminate them. When ...

Waiting to eat when your food arrives first feels polite--but it may be mostly for your own peace of mind. Researchers found people feel far more uncomfortable breaking the "wait until everyone is served" rule than they expect others would feel ...

Researchers have discovered a brain activity pattern that can predict which people with mild cognitive impairment are likely to develop Alzheimer's disease. Using a noninvasive brain scanning technique and a custom analysis tool, they detected subtle ...

Microscopic ocean algae produce a huge share of Earth's oxygen--but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters. Climate-driven changes may reduce iron delivery to ...

Florida State University scientists have engineered a new crystal that forces atomic magnets to swirl into complex, repeating patterns. The effect comes from mixing two nearly identical compounds whose mismatched structures create magnetic tension at ...

Scientists observing the red giant star R Doradus have found that starlight isn't strong enough to drive its stellar winds, overturning a long-standing theory. The dust grains around the star are simply too small to be pushed outward by light alone. ...

A small group of people experience no pleasure from music despite normal hearing and intact emotions. Brain imaging reveals that their auditory and reward systems fail to properly communicate, leaving music emotionally flat. Researchers developed a . ...

Scientists at Fermilab's MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision measurements showed neutrinos behaving exactly as ...
