Phys.org / The algorithmic feed on X could be shifting political views toward conservatism
Turning on the "For You" algorithm on X (formerly Twitter) may shift users' political opinions toward more conservative views, suggests research involving nearly 5,000 X users. These effects are shown to persist even after ...
Phys.org / New chip-scale microcomb uses lithium niobate to generate evenly spaced light
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a photonic chip, a breakthrough ...
Phys.org / Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
Phys.org / How choices made by crowds in a train station are guided by strangers
In crowds, most people are strangers to you, and everyone else for that matter. However, until now, the effect of stranger-to-stranger interactions on the choices people make in crowds has not been properly examined. Ziqi ...
Phys.org / Storms reveal rare 2,000-year-old footprints on Scottish beach
Storms that recently ravaged Britain's coastline have revealed 2,000-year-old footprints on an Angus beach—one of only a handful of locations in the U.K. where markings of this kind have ever been discovered. The imprints ...
Phys.org / New 'Mars GPS' lets Perseverance pinpoint its location within 25 centimeters
Imagine you're all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to inform you exactly where you are. That's what NASA's Perseverance ...
Phys.org / Quantum trembling: Why there are no truly flat molecules
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a ...
Phys.org / Phonon lasers unlock ultrabroadband acoustic frequency combs
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally ...
Phys.org / Why some objects in space look like snowmen: Gravitational collapse may shed light on contact binaries
Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that could be responsible for their ...
Tech Xplore / New AI software set to accelerate delivery of vital net-zero infrastructure
New software, developed by the University of Sheffield spin-out AENi aims to transform how the world's essential net-zero infrastructure is planned. The new digital platform will help the organizations shaping the world's ...
Phys.org / Nature-inspired method forms ZnO quantum dots in solid crystals at room temperature
In nature, tiny crystals known as nanocrystals are formed slowly over many years. Rocks and minerals react with air, water, and carbon dioxide in a process called chemical weathering. These reactions happen gently, at room ...
Medical Xpress / Red blood cells soak up sugar at high altitude, protecting against diabetes
Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But the mechanism of this protection has remained a mystery. ...
