Tech Xplore / 55% of U.S. teens have used AI to create sexualized images, survey finds
In a survey study of U.S. teens, more than half (55.3%) reported that they had created at least one image using nudification tools, which use generative artificial intelligence (GenAI) to show what an individual may look ...
Tech Xplore / Swapping batteries for hydrogen gives drones a whole new range
Researchers have built a drone that runs on hydrogen, to replace battery-powered drones that are too heavy and have too short a range. This technology could help fix power outages faster and replace dangerous helicopter missions ...
Phys.org / Rapid melting of Antarctic sea ice is largely driven by ocean warming, research reveals
Sea ice around Antarctica expanded for several decades until a dramatic decline in 2015. The reasons behind this are revealed by research led by the University of Gothenburg, which is published in Nature Climate Change.
Medical Xpress / Are psychedelics better than antidepressants? New study says no
Psychedelic-assisted therapy may be no more effective than traditional antidepressants when patients know what drugs they are actually taking, according to a first-of-its kind analysis that compared how well each type of ...
Medical Xpress / Stopping GLP-1 drugs can quickly erase cardiovascular benefits
Following a rapid increase in popularity of GLP-1 drugs for diabetes and weight loss, such as semaglutide and tirzepatide, approximately one in eight U.S. adults now take these medications, which also provide cardiovascular ...
Phys.org / 3D model predicts mosquito flight paths from sight and CO₂ cues
A mosquito finds its target with the help of certain cues in its environment, such as a person's silhouette and the carbon dioxide they exhale. Now researchers at MIT and Georgia Tech have found that these visual and chemical ...
Phys.org / NASA hauls its repaired moon rocket from the hangar back to the pad for an early April launch
For the second time this year, NASA moved its moon rocket from the hangar out toward the pad Friday in hopes of launching four astronauts on a lunar fly-around next month.
Phys.org / Ultrathin BiFeO₃ breaks the 30 nm limit, delivering fourfold stronger piezoelectricity
Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric materials, such as lead ...
Phys.org / Asteroid Bennu's rugged surface baffled NASA—now, we finally know why
In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier observations from Earth-based ...
Phys.org / Beavers can convert stream corridors to persistent carbon sinks
Beavers could engineer riverbeds into promising carbon dioxide sinks, according to a new international study led by researchers at the University of Birmingham. The paper, published in Communications Earth & Environment, ...
Phys.org / Ice satellite detects powerful geomagnetic storm with precision
It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth's magnetic field. But that is just what ESA's CryoSat mission did earlier this ...
Phys.org / Snail-derived compound could be a safer anticoagulant compared to heparin
For more than a century, heparin has been the go-to anticoagulant to prevent harmful blood clots in blood vessels or the heart from forming or getting larger. However, a major side effect is an increased risk of excessive ...
