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 / Airborne desert dust may warm climate far more than expected, new analysis shows
Atmospheric dust plays a dual role in Earth's climate: it reflects some sunlight back into space while also absorbing and retaining the planet's heat like an insulating blanket. But while dust likely cools the planet overall, ...
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 / How a free flow of information can amplify incorrect ideas
The idea that information should flow freely is deeply embedded in the design of social media. The assumption is that the more information is produced and shared, the better. However, simulations by a team of scientists including ...
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 ...
Phys.org / Research reveals why beavers are getting busy sooner in spring
A University of Alberta study has whittled down climate-related reasons beavers are emerging earlier onto the ice from their lodges in the spring—a shift that helps them store more winter food but could also lead to more ...
Phys.org / Rainforests can buffer rising CO₂ in the short term—but this comes at a cost
Tropical forests are among the world's most important carbon sinks. A new study by the Technical University of Munich (TUM), the University of Vienna, and Brazil's National Institute for Amazonian Research suggests that even ...
Phys.org / New microscope reveals previously hidden differences in photosynthetic light-harvesting antennae
How do photosynthetic organisms harvest light so efficiently? To help answer this question, researchers have developed an ultrafast transient absorption microscope with sensitivity approaching the single-molecule level.
Phys.org / Egg-scanning AI may let hatcheries sort life, death and sex before chicks emerge
Eggs and poultry provide important sources of protein globally, driving a major industry with large economic impacts. Challenges to hatchery operations include embryo mortality, fertility, sex determination, and eggshell ...
Phys.org / Antarctica's ice shelves are vulnerable to melting from below—knowing how far ocean heat reaches is crucial
A rare dataset collected by instruments at the point where Antarctica's largest ice shelf begins to float reveals ocean processes that drive melting at this critical part of the continent.
Phys.org / Why do high-speed particles bounce higher in wet collisions?
Researchers have uncovered a counterintuitive phenomenon in collision dynamics: high-speed particles bounce back from wet walls much more strongly than expected. Integrating experimental observations with advanced numerical ...
Phys.org / Organic matter diversity determines how much iron is available for marine life, study finds
How much of the essential trace element iron remains available for marine life in the ocean depends critically on the diversity of organic molecules in seawater, according to new research published in Nature Communications ...
