After a heavy rain, rivers often turn brown with sediment, sand, silt and soil washed from the landscape that play a vital role in shaping rivers.

The World Health Organization (WHO) has recommended prioritizing the Ervebo vaccine for testing in a clinical trial in the Democratic Republic of the Congo. The vaccine was originally developed to protect against Zaire ebolavirus, ...

Researchers at the Surrey Space Centre (SCC) found that extreme space weather events can significantly increase radiation exposure at typical flight altitudes of 8–14 km (5–9 miles) and trigger faults in aircraft electronics—posing ...

Most batteries spend more than 70% of their lifetime at rest. Yet few studies have examined calendar aging, which is how a battery degrades when it is neither charging nor being used.

From nuclear energy to lab-grown meat, the list of effective but unpopular climate solutions is long. A new University of Colorado Boulder study sheds light on why people reject or accept some proposed sustainability technologies: ...

Climate change is largely to blame for water scarcity. The low water levels in European rivers this summer speak volumes in that respect.

Scientists have long been fascinated by two promising classes of antibiotics that disable RNA polymerase (RNAP). They knew that these drugs could grind gene expression to a halt in several pathogens, including the bacterium ...

Fields, parks and lawns across Europe have turned to straw this summer. Landscapes thousands of years old have been revealed as green outlines against yellow backgrounds, where ancient underground walls and ditches retain ...

More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, ...

University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. ...

Researchers have developed a full-color near-eye display that uses three stacked holographic gratings, each engineered to direct red, green or blue light. The new design could help advance compact, energy-efficient augmented ...
