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 / 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 / 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 / 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 / Thundering footsteps warn caterpillars of lethal ladybeetle attacks
Diminutive warty birch caterpillars (Falcaria bilineata), less than 1.5mm long, ardently defend their leaf tip homes from invading caterpillars by scraping and pounding the leaf to warn off potential invaders. But how might ...
Phys.org / A new capability to detect chemical weapons involves two existing methods
In the aftermath of suspected chemical attacks, investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) step in to collect chemical, environmental, and biomedical samples. Thorough forensic laboratory ...
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 / 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 / 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 / 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 ...
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 / 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, ...
