In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling ...

Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary ...

Researchers from Leiden University, University of York, University of Barcelona/IQTCUB/ICREA and The Francis Crick Institute report a new class of experimental compounds that powerfully block influenza viruses. The findings ...

Researchers from Xi'an Jiaotong-Liverpool University (XJTLU) in China have developed a streamlined process that makes it easier to produce tiny therapeutic particles released by cells, called exosomes, which are being explored ...

Scientists in Geneva took some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive that has been deemed a success.

Methane is a powerful greenhouse gas that is second only to carbon dioxide in driving up global temperatures. But it doesn't linger in the atmosphere for long thanks to molecules called hydroxyl radicals, which are known ...

Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist ...

For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big ...

A research team led by the Museum für Naturkunde presents the first evidence that several bat species produce courtship songs in the immediate rotor-swept zone of wind turbines while circling around the nacelle. Data from ...

Plants need water, light, and air to thrive. But when they transport water from the soil up to their leaves, they defy gravity. Scientists describe this astonishing phenomenon as "negative water potential," a form of negative ...

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research ...

Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. ...
