Phys.org / Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves
Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there ...
Phys.org / Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate ...
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 / 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 ...
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 / 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 / Egypt fossils show modern ocean fish rose rapidly after dinosaur extinction
The extinction that ended the Age of Dinosaurs is best known for clearing the way for the Age of Mammals on land. Scientists have long suspected that the same catastrophe also transformed life in the seas, opening ecological ...
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 / Half-ton early bovines roamed 4-million-year-old grasslands in Europe
The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June ...
Phys.org / Real-time fish interaction enlarges young guppy brains, while screen time falls short
Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. ...
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 / 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.
