Phys.org / North Sea 'lost world' had habitable forests during the last Ice Age, study shows
Forests were growing on the now-submerged landmass of Doggerland thousands of years earlier than previously believed, according to a major new sedimentary ancient DNA (sedaDNA) study led by the University of Warwick. The ...
Phys.org / AI weather models show promise for hurricane forecasts, but new study finds key physical limitations
Artificial intelligence is rapidly transforming weather prediction, enabling forecasts that once required hours of supercomputing time to run in just minutes. But as AI tools play an expanding role in high-stakes hazard modeling, ...
Phys.org / Fish study shows that sexual harassment behavior might matter for ecosystems
For decades, ecologists have known that how a species looks or eats affects its environment. But a new study by researchers at the University of California, Santa Cruz, shows that social behavior related to mating can be ...
Phys.org / Fluid simulation at unprecedented scale provides toolkit for fundamental physics and applied fluid engineering
What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at which a fluid filled ...
Phys.org / Study finds nanocube cation exchange can begin on one face, not six
In a paper published today in Nature Synthesis, a team from the lab of University of Chicago Pritzker School of Molecular Engineering (UChicago PME) and Chemistry Department Prof. Paul Alivisatos explores the role of cation ...
Phys.org / Researchers mix X-rays and optical light to track speedy electrons in materials
To unlock materials of the future, including better photocatalysts or light-switchable superconductors, researchers need to understand how the valence electrons within materials respond to light at the atomic scale. Materials ...
Phys.org / Florida's most at-risk bat moves into safer artificial roosts
Finding bats in the attic or under roof tiles is no homeowner's idea of fun. But Florida's endangered bonneted bats have few natural options left. With a dwindling number of large, old trees with cavities—their preferred ...
Phys.org / King penguins are the rare species benefiting from a warming world. But that could change
The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other—like flowers blooming too early and pollinating bees arriving too late. But researchers ...
Phys.org / Artificial kinetochores take the pressure off aging chromosomes during meiosis
For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes becomes more prone to ...
Phys.org / Ancient DNA reveals Ice Age mammals thrived after volcanic eruption
For the first time, scientists have used DNA preserved in ancient sediments to examine how a major natural disaster affected animal populations. A new study of a catastrophic volcanic eruption during the Ice Age has found ...
Phys.org / Trouble swallowing? A nanogel tweak may keep therapeutic stem cells alive longer
Swallowing is a fundamental human function that supports nutrition and communication. Damage to swallowing muscles can reduce quality of life and even lead to aspiration pneumonia or malnutrition. Many patients suffer from ...
Phys.org / Uncovering the hidden bacteria often mistaken for cholera
Scientists have created a genomic blueprint for Aeromonas bacteria, which can cause antibiotic-resistant diarrheal disease—with symptoms often misidentified as cholera—in humans and animals.
