Phys.org / Physicists trace the sun's magnetic engine, 200,000 kilometers below its surface
Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and migrate toward the ...
Tech Xplore / AI chatbots' tendency to always agree may reinforce delusions in vulnerable users
The integration of large language model-based AI chatbots into multiple facets of our everyday lives has opened us up to advantages that would have been considered impossible even a decade ago. The same development has, however, ...
Phys.org / Nanoengineered spintronic device can store data in four different ways
Over the past decades, electronics engineers have been trying to develop increasingly smaller devices that can store information reliably, even when they are not powered on. A promising type of non-volatile memory device ...
Phys.org / Solar energy transforms polystyrene waste into valuable chemicals using sulfur
Turning waste into wealth may no longer be just a marketing slogan, as a team of researchers in China has found an eco-friendly way to do exactly that. The abundant sunlight our planet receives was put to use for transforming ...
Phys.org / Graphene sensors stay stable in liquids, boosting sensitivity up to 20 times
Accurately measuring small shifts in biological markers, like proteins and neurotransmitters, or harmful chemicals in the water supply, can identify critical problems before they have a chance to impact patients or the environment. ...
Tech Xplore / Record efficiency achieved for perovskite-silicon triple-junction solar cells
Researchers from the Photovoltaics and Thin-Film Electronics Laboratory (PV-Lab) in EPFL's School of Engineering and CSEM have developed a new solar cell that combines exceptional voltage, high efficiency, and scalable manufacturing. ...
Phys.org / What's in your lipstick and water? New test flags hidden mutagens
Substances capable of mutating human genetic material—altering and permanently damaging it—are present in many everyday products. Researchers at Justus Liebig University Giessen (JLU) have, for the first time, detected ...
Phys.org / 'Conflict entrepreneurs': Examining divisive political rhetoric and the pursuit of celebrity by politicians
American politics is increasingly characterized by high levels of polarization and divisive rhetoric, despite stated preferences among voters for civility and substantive debate. Sean J. Westwood and colleagues sought to ...
Medical Xpress / Metformin use linked to lower odds of new-onset neovascular age-related macular degeneration
Metformin use is associated with reduced odds of new-onset International Classification of Diseases (ICD) coding of neovascular age-related macular degeneration (nAMD), according to a study published online Jan. 30 in Ophthalmology ...
Tech Xplore / Compostable robot endures over 1 million uses before becoming plant food
The rapid proliferation of robots and electronic devices is placing the world under a new and growing environmental burden. According to the United Nations Institute for Training and Research (UNITAR), global electronic waste ...
Phys.org / Researchers explore new ways to neutralize germs using light-activated nanomaterials
At Empa, an interdisciplinary research institute for materials science and technology within the ETH Domain, researchers are working on ways to kill harmful bacteria and viruses. In the Nanomaterials in Health Lab, headed ...
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 ...
