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 ...
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 / New route to tailor-made diamond nanoparticles holds promise for quantum applications
Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising ...
Phys.org / Water-wave tweezers steer tiny 'surfers' without touching them
Summer brings with it the sight of surfers moving seamlessly across wave crests, with ocean waters carrying them along coastlines. A team of scientists has now created a similar phenomenon—with small objects rather than surfers—that ...
Phys.org / Ancient cave lion genomes reveal a distinct lineage
A new study on multiple genomes from the extinct cave lion has discovered that it represented a highly distinct evolutionary lineage, which separated from modern lions more than a million years ago. The results also show ...
Phys.org / Printed manga may give the brain a storytelling advantage
A new study by researchers at the University of Tokyo explores whether reading manga on paper or on a tablet changes how the brain understands and remembers stories. Participants first read the opening half of a two-part ...
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 / 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 / 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 / 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 / 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 ...
