Phys.org / Temperature gaps help sneeze clouds stay denser and travel farther, experiments show
When a person coughs or sneezes, they expel a cloud of microscopic particles capable of carrying viruses and bacteria that act as vectors for respiratory diseases such as flu, COVID-19 or tuberculosis. Understanding how these ...
Dialog / Research could pave the way for more resilient winter cereals in warmer climates
The arrival of winter marks not only a change in weather, temperature, and day length, but also a change in our activity and behavior. The social outdoor events and trips to the beach over summer soon become a distant memory, ...
Phys.org / SWOT satellite gets clearer ocean data after fix for hidden underwater wave interference
Florida State University research published in Science Advances demonstrates a new framework for predicting the motion of kilometer-scale underwater waves that complicate satellite readings of the ocean.
Phys.org / Detailed molecular picture of tooth enamel reveals adaptations to diet
From chewing to chomping to grinding, teeth suffer from a lifetime of repeated mechanical stress. It makes sense, then, that enamel is one of the hardest natural materials.
Phys.org / Whiskey chemistry propels microscopic machines through liquid
Whisky-inspired chemicals could help power a new generation of microscopic machines, according to researchers who have discovered a way to make tiny particles "swim" through liquid using compounds linked to the production ...
Phys.org / Dynamic nanogates let longer molecules pass faster through flexible pores
A research team led by Professor Shuichi Hiraoka at the University of Tokyo and Professor Masanori Tachikawa at Yokohama City University has quantitatively analyzed how molecules pass through dynamic nanoscale pores using ...
Phys.org / Programmable chemistry unlocks drugs only in target cells, aiming to cut side effects
Potent drugs like chemotherapy can be life-saving, but often with life-threatening side effects. Notably, they can be indiscriminate, killing both cancer cells and healthy cells in one swoop. Increasing a drug's on-target ...
Phys.org / Out-of-plane ice bridges reveal new way to suppress frost spreading
A research team led by Professor Nenad Miljkovic in The Grainger College of Engineering at the University of Illinois Urbana-Champaign has published a breakthrough study in Nature Physics. The work reports the first experimental ...
Phys.org / Integrating citizen science with experimental data uncovers how switchgrass adapts flowering by region
In its native habitat, switchgrass flowered earlier when growing farther north. In experiments with diverse genetic samples, it flowered earlier in the south.
Phys.org / Open-source software unlocks rapid DNA structure generation and analysis in one workflow
Computational chemists at the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences have developed a comprehensive software suite to create accurate models of DNA in biomolecular assemblies. Called MDNA, ...
Phys.org / Armed with AI, study identifies prey from predator crunching sounds
Interactions between hard-shelled marine mollusks such as clams and snails and their predators play a critical but largely unseen role in shaping coastal ecosystems. These organisms help stabilize shorelines, filter water ...
Phys.org / Climate change may shift hailstorms toward Earth's poles—new study
Everyone has a storm story—whether it's that time you just escaped a downpour, or the hailstorm that wrote off your car. Even though hailstorms are relatively rare, they cause significant damage. Two new studies shed light ...
