Phys.org / An ionic fix for frost: Electrostatic defrosting removes ice without heat or chemicals
During winter months, frost can unleash icy havoc on cars, planes, heat pumps, and much more. But thermal defrosting with heaters is very energy intensive, while chemical defrosting is expensive and toxic to the environment.
Phys.org / How to spot life in the clouds on other worlds
Cloud cover is bad for picnics and for viewing stars through a telescope. But an exoplanet with dense or even total cloud cover could help astronomers search for signs of life beyond our planet.
Phys.org / Bamboo dishes may leach pesticides and melamine into food
So-called "eco-friendly" bamboo and other bio-based dishes, often marketed as natural and safe alternatives to plastic, may release potentially harmful chemicals into food, according to a new study led by researchers at the ...
Phys.org / AI can deliver personalized learning at scale, medical education study shows
A new Dartmouth study finds that artificial intelligence has the potential to deliver educational support that meets the individual needs of large numbers of students. The researchers are the first to report that students ...
Phys.org / Non-harmonic two-color femtosecond lasers achieve 1,000-fold enhancement of white-light output in water
Scientists at Japan's Institute for Molecular Science have achieved a 1,000-fold enhancement in white-light generation inside water by using non-harmonic two-color femtosecond laser excitation. This previously unexplored ...
Phys.org / Monk seal acoustic study quadruples known call types and detects novel communication strategy
New research led by UH Hawaiʻi Institute of Marine Biology (HIMB) Marine Mammal Research Program (MMRP) has drastically increased the understanding of Hawaiian monk seal (Neomonachus schauinslandi) underwater sound production, ...
Phys.org / Key 'fingerprint' reveals slowdown of Atlantic Meridional Overturning Circulation
The Atlantic Meridional Overturning Circulation (AMOC), an ocean current system that transports heat from the tropics to the North Atlantic, plays a vital role in regulating the global climate. Most climate models project ...
Phys.org / Destroying crazy ant nest structure makes them vulnerable to pathogens
Invasive tawny crazy ants have been wreaking havoc across the U.S. Gulf Coast from Florida to Texas, disrupting ecosystems and causing headaches for homeowners. Now scientists at The University of Texas at Austin have devised ...
Phys.org / Researchers track massive ice loss from Berry Glacier in West Antarctica
Berry Glacier, a tributary of the Getz Ice Shelf in West Antarctica, has deteriorated dramatically in the past three decades, according to researchers in the Department of Earth System Science at the University of California, ...
Phys.org / Electric fields steer nanoparticles through a liquid-filled maze, offering improved drug delivery and purification
In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with an electrical charge—from ...
Phys.org / How life first got moving: Nature's motor from billions of years ago
Research led by the University of Auckland has cast light on the evolutionary origins of one of nature's first motors, which developed 3.5 billion to 4 billion years ago to propel bacteria.
Phys.org / AI is powering the search for America's critical minerals
They power green energy, enhance defense systems, and drive the future of microelectronics. Known as critical minerals, elements like lithium, cobalt, and nickel are vital to national security and innovation. Yet the U.S. ...
