Phys.org / Fake survey answers from AI could quietly sway election predictions
Public opinion polls and other surveys rely on data to understand human behavior. New research from Dartmouth reveals that artificial intelligence can now corrupt public opinion surveys at scale—passing every quality check, ...
Phys.org / Ultracold potassium-cesium molecules assembled in absolute ground state
Researchers from Hanns-Christoph Nägerl's group have produced the world's first ultracold KCs molecules in their absolute ground state. Starting by mixing clouds of potassium and cesium atoms cooled almost to absolute zero ...
Phys.org / Lethal dose of plastics for ocean wildlife: Surprisingly small amounts can kill seabirds, sea turtles and marine mammals
By studying more than 10,000 necropsies, researchers now know how much plastic it takes to kill seabirds, sea turtles, and marine mammals, and the lethal dose is much smaller than you might think. Their new study titled "A ...
Phys.org / Delaying net zero may mean centuries of hotter, longer, more frequent heat waves
We must prepare for a future of frequent, deadly heat waves, which will worsen in severity the longer it takes to reach net zero, new research has shown.
Phys.org / Astronomers reveal flat 'Diamond Ring' in Cygnus X is a burst bubble remnant
An international team led by researchers from the University of Cologne has solved the mystery of an extraordinary phenomenon known as the "Diamond Ring" in the star-forming region Cygnus X, a huge, ring-shaped structure ...
Phys.org / Lethal aggression among chimpanzees tied to larger territories and higher infant survival
The Ngogo chimpanzees of Uganda's Kibale National Park have long been known for violent clashes with neighboring groups, often resulting in deaths—a phenomenon sometimes described as "chimpanzee warfare."
Phys.org / Open-access tool navigates expanding world of metal–organic frameworks for easier discovery
A new open-access tool created by University of Toronto Engineering researchers provides a systematic way to organize and synthesize knowledge about metal–organic frameworks (MOFs)—a class of materials with applications ...
Phys.org / Lead-free alternative discovered for essential electronics component
Ferroelectric materials are used in infrared cameras, medical ultrasounds, computer memory and actuators that turn electric properties into mechanical properties and vice-versa. Most of these essential materials, however, ...
Phys.org / Traditional Hawaiian fishponds help shield fish from climate change impacts
Traditional Hawaiian fishponds (loko iʻa) are emerging as a model for climate resilience, according to a study from the University of Hawaiʻi at Mānoa's Hawaiʻi Institute of Marine Biology (HIMB). The research, published ...
Phys.org / Prescribed burning helps store forest carbon in big fire-resistant trees, long-term Sierra Nevada study shows
A two-decade-long experiment in the Sierra Nevada found that regular prescribed burns promote carbon sequestration in live trees and plants, maintaining forests' long-term ability to store carbon while also reducing wildfire ...
Phys.org / Sugar transporters found to boost aminoglycoside antibiotic entry into bacteria
Aminoglycosides are antibiotics effective against a wide range of bacteria including Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Until now however, their mode of entry into bacteria has remained unknown. ...
Phys.org / Severe floods cut global rice yields, threatening food security for billions
Severe flooding has slashed global rice yields in recent decades, threatening food security for billions of people who depend on the grain. The losses amounted to approximately 4.3%, or 18 million tons of rice per year, between ...
