Phys.org / Engineers solve puzzle of Arctic sea ice movement
Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially ...
Phys.org / Compact optical screen could pave the way for cheaper infrared cameras
New research led by the ARC Center of Excellence for Transformative Meta-Optical Systems (TMOS) at the University of Melbourne demonstrates a new way to make invisible infrared light visible without relying on the expensive ...
Phys.org / Fungi neutralize spruce defense mechanisms with sugar
A research team at the Max Planck Institute for Chemical Ecology discovered a previously unknown strategy by which certain fungi neutralize spruce defense compounds. These fungi are introduced into trees by bark beetles, ...
Phys.org / Bacterial invasion proteins could improve detection of live crop pathogens
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published ...
Phys.org / Tiny oyster larvae rely on gravity to feed
Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make them substantially heavier than the surrounding seawater. A new study led by the Woods Hole Oceanographic Institution ...
Phys.org / Muon rings enable precise calibration of telescopes at the Cherenkov Telescope Array Observatory
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. ...
Phys.org / Dual findings reveal how to control coherence in plasmonic nanolasers
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, ...
Phys.org / AI reveals novel nighttime feeding behaviors in right whales
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 ...
Phys.org / Speeding glaciers drive half a century of polar ice loss
The longest satellite record ever assembled shows that Greenland and Antarctica have lost 11.3 trillion metric tons of ice since the 1970s, raising global sea level by more than 3 centimeters (1.2 inches)—and that most of ...
Phys.org / Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show
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, ...
Phys.org / Beach-burrowing beasties may shovel more sand than any other animal on Earth
At just an inch (2.5 centimeters) long, the sand hoppers skipping across California's Isla Vista Beach at dawn don't exactly look like a force of nature. But a new study reveals that these shrimp-like creatures might be doing ...
Phys.org / Heat-related lost labor emerges as a major cost of carbon emissions
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.
