Phys.org / Intermolecular collisions may explain why organic radical fluids become unusually magnetic
Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously ...
Phys.org / Random deformation lets glassy materials store precise mechanical memories, simulations reveal
Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can "remember" past mechanical ...
Phys.org / Data suggest 'red flag' laws are linked to sustained reductions in arrests
Individuals subject to extreme risk protection orders (ERPOs), or "red flag" laws, were significantly less likely to be arrested—including for violent and firearm-related offenses—while the orders were in effect than in the ...
Phys.org / Your body's secret sugar code could predict disease years before it strikes
Scientists have found that hidden health signals coating your cells could change medicine forever. The new study by Edith Cowan University (ECU) School of Medical and Health Sciences has shown sugar molecules in your body ...
Phys.org / Nanomedicine discovery uses salt to overcome major obstacle in gene therapy
Researchers at the University of Houston's College of Pharmacy have discovered an unexpectedly simple strategy to improve the performance of mRNA vaccines and gene therapeutics: adding salt. The findings, published in Small, ...
Phys.org / Young coqui frogs 'play it safe' when disease strikes, study finds
For a frog no bigger than a fingernail, survival depends on how it spends every bit of energy. New research from the University of Florida shows that young frogs prioritize growing quickly even when infected with a deadly ...
Phys.org / A heat sensor for living cells could offer new views of cell metabolism, rapid antibiotic testing
When living cells grow, divide or respond to drugs, they give off tiny amounts of heat that offer information about what the cells are doing. But because these heat signals are so vanishingly small, they have traditionally ...
Phys.org / Artificial cells gain porous membranes, enabling lab reactions and drug release
Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their membranes—unlike those of real cells—have been virtually impermeable. Researchers at the Max Planck Institute ...
Phys.org / Chemists uncover new metal carbene radical cross-coupling by merging two catalytic cycles
In an effort to open the door to new and useful products, chemistry researchers are on the continual lookout for processes that unlock important molecules and the bonds that can put them together. Such is the case for UC ...
Phys.org / Mongooses prepare for likely future battles with powerful enemies, study finds
Dwarf mongooses anticipate encounters with rival groups and adjust how they move, communicate and defend resources beforehand, according to new research from the University of Bristol. The study, published in Nature Ecology ...
Phys.org / 50-megapixel Earth models capture storms in unprecedented detail—but four consistent blind spots remain
Traditional global climate models were like early digital cameras—they had only about 10,000 pixels to cover the entire planet. At that low resolution, big storm systems looked like blurry blobs. You couldn't see their true ...
Phys.org / Darkness unlocks more ordered nanotubes in light-responsive molecular assemblies, study suggests
Life on Earth has evolved under an uninterrupted rhythm of day and night. While light provides the energy that powers countless molecular processes, periods of darkness often allow biological systems to reorganize, recover ...
