Phys.org / Low oxygen could limit insects' uphill escape from climate warming
Reduced oxygen levels and air pressure at higher elevations may limit insects' ability to move upslope to escape a warming climate, with potential consequences for the essential services they provide, like pollination, according ...
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Phys.org / El Niños have been more intense over the last 40 years than in the previous 1,000 years, coral records reveal
As an El Niño of historic proportions is taking shape in the tropical Pacific, a University of Michigan study has found that El Niño events have become nearly 40% stronger in the last 40 years than they were in the preindustrial ...
Phys.org / Fast but error-prone AI assists in solving a decades-old fluid mechanics problem in five weeks
An AI assistant helped University of Colorado Boulder researchers solve a mathematical problem that had challenged their lab for a year and a half, though it made subtle errors along the way. The breakthrough could improve ...
Phys.org / Hitting bacteria hard and early with diverse phage cocktails may curb resistance
As multidrug antibiotic resistance emerges as a potent public health challenge, medical science has renewed attention on the potential for bacteriophage therapy. Bacteriophages, or phages, are viruses that target, infect ...
Phys.org / AI model designs potentially stable protein sequences beyond those found in nature
A protein's function is determined by its structure, and structure—the way a protein folds—is determined by its sequence of amino acids, the building blocks of proteins.
Phys.org / Tiny oxygen gaps may determine whether next-generation memory films store data well
Researchers have captured in real time the "birth moment" when the performance of a next-generation memory material is determined. The key lies in controlling oxygen vacancies, microscopic defects created when oxygen atoms ...
Phys.org / Discovery reveals rapid pathways to complex aromatic molecules in space
A team of researchers led by the University of Hawaiʻi at Mānoa Department of Chemistry has uncovered a faster way large carbon-based molecules may form in space, helping solve a long-standing mystery about how some of the ...
Phys.org / Primed and ready to fight, a nematode pheromone arms plants to battle pathogens
When cold and flu season comes around, we take steps like getting our flu shots and taking immune supplements to strengthen our bodies' defenses against pathogens. Plants face pathogenic threats, too. Plant pathogens can ...
Phys.org / Boosting soybean protein: Zinc and sulfur essential in sustainable crop production
Soybean is a critical element of the global food supply: Between its use for animal feed and human consumption, it accounts for roughly two-thirds of plant-based protein meal output worldwide. Canada is a global leader in ...
Phys.org / Vehicle-mounted spectroscopy system detects methane in real time
Researchers have developed a vehicle-mounted spectroscopy system that can reliably detect methane in real time while driving. Using a moving vehicle to detect methane could make it easier to locate hidden methane emissions ...
Phys.org / Tsunami of dirt: What caused Nepal's deadly glacial flood?
More than 150 people are dead and hundreds more are missing after an enormous wave of water, ice, mud and rock cascaded more than 170 kilometers (106 miles) down the Bhote Koshi River valley in Nepal. The valley is the main ...
