Phys.org / AI gets water right: How a hydration shield helps proteins keep their shape
A study published in the Journal of the American Chemical Society reports that artificial intelligence can enhance protein stability in an unexpected way—by engineering the water around a protein, not just the protein itself. ...
Phys.org / First cases of highly pathogenic avian influenza in northern elephant seals confirmed in California
Seven weaned elephant seal pups in California's Año Nuevo State Park tested positive for highly pathogenic avian influenza (HPAI) H5N1, the U.S. Department of Agriculture's National Veterinary Services Laboratory confirmed ...
Phys.org / Humanity's oldest geometries, engraved on ostrich eggs
At several archaeological sites in southern Africa, hundreds of highly unusual fragments of ostrich eggs have been found. Dating back more than 60,000 years, the shells were engraved by groups of Homo sapiens who lived in ...
Phys.org / Ion bombardment triggers a reliable quantum switch in tantalum disulfide crystals
When you toss a coin, you put it into a higher-energy state until it falls back down again. It can then end up in one of two possible states: heads or tails. No matter which state the coin was in before, after the toss both ...
Phys.org / Bacterial pathogens build antibiotic-resistant 'bunkers' using filament scaffolds
Researchers have discovered and characterized at the atomic level a mechanism that enables bacterial pathogens—including hospital bacteria Acinetobacter baumannii and Pseudomonas aeruginosa—to assemble antibiotic-resistant ...
Phys.org / Worming out the molecular secrets behind collective behavior
Studying social behavior is crucial for understanding how certain neuromodulatory pathways—like the serotonin pathway, which influences mood and social interactions—are regulated. Kavita Babu, Professor at the Centre ...
Phys.org / Robot pollinator uses computer vision to shake flowers and boost indoor farm yields
Indoor farms, also known as vertical farms, are popular among agricultural researchers and are expanding across the agricultural industry. Some benefits they have over outdoor farms include the year-round production of food ...
Phys.org / Which cell measurements matter most? AI tool helps researchers see the bigger picture
Studying gene expression in a cancer patient's cells can help clinical biologists understand the cancer's origin and predict the success of different treatments. But cells are complex and contain many layers, so how the biologist ...
Phys.org / Land plants began reshaping Earth 455 million years ago, scientists discover
Pinpointing when early land plants colonized terrestrial environments and began influencing Earth's systems is a core question in the evolution of the Earth system. A research team led by Prof. Zhao Mingyu at the Institute ...
Phys.org / The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses
Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent ...
Phys.org / New michelin star jellyfish discovered in Japanese aquaria
Researchers have reported the discovery of a new species of jellyfish, Malagazzia michelin, marking only the second species of its genus ever found in Japanese waters. Led by Takato Izumi of Fukuyama University, the discovery ...
Phys.org / Tropical flowers are blooming weeks later than they used to through climate change
Climate change has caused some tropical plants to flower earlier or later than they used to; in some cases by a matter of weeks or even months, according to a study of 8,000 flowers across more than two centuries, published ...
