Phys.org / AI surrogate accelerates nonlinear optics simulations by orders of magnitude
Simulating the nonlinear optical physics that underlies ultrafast laser systems is computationally demanding—a practical bottleneck in settings that require rapid feedback. A study by researchers at Stanford University, University ...
Phys.org / The shoal remembers: How signs of a collective memory shape a predator-prey arms race
Beneath the tropical trees of southern Mexico, enormous shoals of sulfur mollies blanket the water surface of toxic sulfur springs, where survival depends on collective defense against relentless attacks from predatory birds. ...
Phys.org / The fog is alive: Droplets host bacteria that clear toxins from our air
What if fog isn't just misty air, but a living ecosystem? This question hung over cloud researcher Thi Thuong Thuong Cao. As a Ph.D. student at Arizona State University, her curiosity led her from knocking on the doors of ...
Phys.org / 'Calm' galaxy cluster hides a violent cosmic scene that took 4 billion years to settle
The galaxy cluster Abell 2029 is sometimes described as "the most relaxed cluster in the universe." This moniker does not arise from some sort of mellow vibe, but rather because of how calm and undisturbed the superheated ...
Phys.org / Scientists dispute hypothesis that climate change will unleash massive agricultural pest populations
The widespread hypothesis that climate warming will result in unprecedented agricultural pest populations and cause food insecurity worldwide is oversimplified, according to a new study by a team led by Mia Lippey, an entomologist ...
Phys.org / Swapping molecular building blocks one by one reveals how receptors tell adrenaline from dopamine
Different receptors respond to different neurotransmitters or hormones, such as adrenaline involved in the fight-or-flight response, or dopamine linked to reward and motivation. Both the receptors themselves and the substances ...
Phys.org / How winds above Tibet quietly replenish water for nearly 2 billion people
The "Asian Water Towers" (AWTs), a high-altitude region with a mean elevation exceeding 4,000 meters, serve as the primary freshwater source for nearly 2 billion people. While the Indian summer monsoon is well known for shaping ...
Phys.org / New tectonic plate boundary could be forming in Zambia, scientists say
Isotope analysis of gas from geothermal springs in Zambia could show that a new continental rift is forming, scientists say. Unexpectedly high helium isotope ratios indicate that a weakness in Earth's crust has broken through ...
Phys.org / JWST maps cosmic web in record detail back to universe's first billion years
Using data from NASA's James Webb Space Telescope (JWST), astronomers led by researchers at the University of California, Riverside have produced the most detailed map of the cosmic web ever made, tracing the network of galaxies ...
Phys.org / Method for measuring energy amounts less than a trillionth of a billionth of a joule could boost quantum computing
The fundamentals of quantum mechanics are minuscule. Scientists constantly home in on finer resolutions to measure, quantify, and control these fundamentals, like photons that carry light and have no mass unless they are ...
Phys.org / Molecular glue could hijack cells' natural machinery to help treat diseases
Proteins do most of the work in our body's cells. But when a protein is too active or does not function properly, it can lead to disease or other health problems. Researchers from the University of Toronto have discovered ...
Phys.org / New quantum protocol breaks distance and speed barriers in fiber networks
Scientists at the University of Science and Technology of China have successfully deployed a multi-mode quantum relay network, achieving matter–matter entanglement over 14.5 kilometers, according to media reports.
