Phys.org / Molecular glasses solve long-standing Arrhenius paradox
Glasses are non-crystalline but solid states of matter in which molecules and atoms are not arranged into a regular crystal lattice, but rather in a disordered pattern. Glassy materials are widely used in various settings, ...
Phys.org / Global mangrove forests rebound, offering hopeful sign for climate and coastal resilience
Mangrove forests, once considered one of the world's most threatened coastal ecosystems, are showing signs of recovery worldwide, according to new research from Tulane University that finds decades of losses largely offset ...
Medical Xpress / Brain circuit that times a state of low metabolism could have implications for space travel
You have gone without food for days, and the temperature drops to near freezing. What do you do? For some animals, the answer is influenced by the brain's circadian clock. Hummingbirds, bats, and mice are among the animals ...
Phys.org / Wildfires reverse decade of ozone cleanup in the United States, study reveals
Ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air, according to a new study titled "Fires reverse progress toward ...
Medical Xpress / Prenatal Zika exposure may trigger vision, hearing and social changes despite seemingly healthy births
Infants exposed to the Zika virus during pregnancy may face hidden developmental challenges, even if they appear healthy at birth. A recent study at the University of Wisconsin-Madison highlights the need for better developmental ...
Medical Xpress / How aging reshapes sensorimotor learning: Older adults may lose explicit strategy but gain implicit adaptation
When most humans reach late adulthood, their ability to coordinate movements and maintain balance, broadly referred to as motor control, tends to gradually decline. While these changes in motor control are widely documented, ...
Phys.org / How Florida's 'war on woke' reframed responsible investment as a threat to 'everyday people'
Fossil fuel companies were a major force behind the United States (US) state of Florida's move to stop banks and pension funds from investing in companies that prioritized environmental and social governance (ESG), new research ...
Phys.org / Portsmouth's wartime Railwaywomen: Postcard documents women who kept railways running during WWI
A newly discovered photographic postcard showing women who kept Portsmouth's railways running during the First World War has been revealed by a researcher at the University of Portsmouth—and he is appealing to local people ...
Phys.org / Teaching AI to design optical surfaces using real-world imperfections
Designing surfaces that precisely control how light behaves at the nanoscale is tricky. Optical Fourier surfaces, which are nanostructured gratings that redistribute light into specific directions and wavelengths, hold enormous ...
Phys.org / Drug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat. The research ...
Phys.org / Why jellyfish can't rise to the surface
Using box jellyfish as an example, researchers from Kiel University show how the physics of density, not behavior or physiology, can prevent animals from reaching the surface even as they actively swim upward.
Phys.org / Dual-use research may outgrow national oversight, analysis of 600,000 papers suggests
A new analysis of approximately 600,000 research papers reveals structural limits to single-country security oversight of dual-use research and identifies trade-offs that policymakers face when strengthening such oversight.
