Washington State University researchers have discovered how a group of coronaviruses circulating in hedgehogs invades host cells, a key to understanding their potential to jump between species and their risk of causing a ...

When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, ...

Research initiated as part of a bachelor's thesis in physics at the Universitat Autònoma de Barcelona (UAB) has culminated in a new analytical description of the muon-based calibration of dual-mirror Cherenkov telescopes. ...

Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: ...

Researchers at the University of Eastern Finland have uncovered two complementary mechanisms that govern coherence in miniaturized lasers composed of metallic nanoparticle arrays incorporated into an optical gain material, ...

Crystals are usually imagined as rigid objects with flat faces and straight edges. A research team led by the University of Osaka has recently created a porous crystal that grows into a spring-like helix. The team also found ...

From social media to the streets of Washington, D.C., the organized white nationalist movement has become more visible in the United States over the past few decades. But the extent of this extremist movement's appeal to ...

Right whales forage near the water's surface at night, putting them at greater risk of potentially fatal collisions with boats, Jay Kirkham at Dalhousie University, Canada, and colleagues report Sept. 16, 2026, in the journal ...

As the climate warms, people are more exposed to heat stress, which depresses productivity and the global economy. A study from the University of California, Davis, quantifies the cost of heat stress on global labor.

By evaluating the health of waterways across the U.S., researchers have identified a network encompassing about one-third of rivers and streams that, if conserved and restored, could sustain the nation's freshwater biodiversity ...

Lichens colonize trees and rocks all over the world. They are symbiotic communities between fungi and photosynthetically active green algae or cyanobacteria, in which both partners benefit from each other: The fungal partner ...

Physicists at Leipzig University and Charles University in Prague have developed a method for changing the swimming style of tiny artificial microswimmers in real time. They can make a single microscopic particle switch at ...
