Phys.org / This ultracold quantum device turns electricity into something far stranger that could unlock sound-based lasers

Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications ...

Phys.org / Natural rubber process boosts tire toughness about tenfold while preserving stiffness

Natural rubber, tapped from trees as latex, is the world's most widely used bio-elastomer. Comprising long molecular chains that make it pliable and stretchy yet highly resistant to cracking and strain, natural rubber is ...

Phys.org / New copper nanozyme shows powerful tumor suppression with high precision

Malignant tumor treatment remains a major challenge due to the limited precision and significant side effects. Copper-based single-atom nanozymes have shown promise for tumor microenvironment-responsive precision therapy, ...

Medical Xpress / A banned chemical still lingers, and its strangest effect may depend on sex, genes and one common vitamin

In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs), affect genetic activity. The research helps explain how biological ...

Phys.org / With a swipe of a magnet, microscopic 'magno-bots' perform complex maneuvers

Under a microscope, a bouquet of lollipop-like structures, each smaller than a grain of sand, waves gently in a Petri dish of liquid. Suddenly, they snap together, like the jaws of a Venus flytrap, as a scientist waves a ...

Phys.org / Bowhead whale recovery reflects century-old whaling patterns

An international study led by Adelaide University has found bowhead whale populations are recovering only in stocks where large areas of hazardous sea ice conditions limited devastating hunting centuries ago. The research ...

Phys.org / Do birds have accents? The fascinating regional differences in birdsong

Birds sing the most about an hour before dawn, when the air is at its stillest. Theoretically, this enables sounds to travel farther, making song up to 20 times more effective than if sung at midday.

Phys.org / An unprecedented Antarctic heat wave hit in the dead of winter—what it signals for the decades ahead

In the middle of the Antarctic winter, during months of darkness when temperatures often dip below −30°C, the continent warmed dramatically. In July and August 2024, temperatures in parts of East Antarctica rose by up to ...

Phys.org / A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride (GaN) material from ...

Phys.org / Journalism classes lack a consistent approach to AI use across institutions

Artificial intelligence is steadily becoming more embedded in journalism; part of how journalists write, edit, research and more. But little is known about how future journalists are learning about the technology. New research ...

Phys.org / Stealthing survivors grapple with a 'gray area' of sexual violation

Nonconsensual condom removal by an intimate partner falls into a gray area of sexual violence, a traumatic experience that exposes survivors to health risks, which they are often expected to manage alone without medical assistance ...

Phys.org / Investigating the disordered heart of glass

Recent research led by the University of Trento reveals that fundamental atomic vibrations remain unchanged also in ultra-stable glasses. This discovery advances the decade-long debate on the physics of disorder and opens ...
