Phys.org / Northern Europe's radiator: Volcanic eruptions in the past may have pushed ocean currents toward collapse
New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning Circulation (AMOC), causing temperatures ...
Phys.org / Specially engineered crystal reveals magnetism with quantum potential
Researchers at the Department of Energy's Oak Ridge National Laboratory, working with international partners, have uncovered surprising behavior in a specially engineered crystal. Composed of tantalum, tungsten and selenium—elements ...
Medical Xpress / Healthier dietary patterns linked to lower colorectal cancer risks in large international study
A large, long-term study following nearly 1 million adults across the United States and Europe has found that dietary patterns associated with lower inflammation and steadier insulin levels are linked to a reduced risk of ...
Tech Xplore / Laughter reveals how we use AI at home
Voice assistants such as Alexa are often marketed as smart tools that streamline everyday life. But once the technology moves into people's homes, interest quickly fades. This is shown by new research in which laughter is ...
Phys.org / Growing number of Americans report experiencing extreme cold, poll finds
Millions in North America kicked off 2026 with bitterly cold temperatures, with many saying it's been years since they've experienced such frigid winter weather.
Medical Xpress / Engineered CAR-NK cells appear more 'attack-ready'
Researchers at the Ribeirao Preto Blood Center and the Center for Cell-Based Therapy (CTC) conducted a study using the NK-92 cell line to test new models of chimeric antigen receptors (CARs) with specific costimulatory domains, ...
Medical Xpress / Brainwaves of mothers and children synchronize when playing together—even in an acquired language
Interbrain synchrony is the simultaneous activity of neural networks across the brains of people who are socially interacting—for example, talking, learning, singing, or working together. Having brains that are thus synchronized ...
Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Phys.org / Why hikers need a backup for the maps on their phones
Four of five Norwegians use digital maps when they are in the outdoors. In just a few years, our mobile phones have gone from being a practical navigation aid to a virtual compass in your backpack. The more we rely on digital ...
Tech Xplore / Safer railroads through ultrasound: Beamforming algorithms can improve track safety inspections
Advances in ultrasound—the same imaging technology that uses sound waves to allow doctors to monitor babies in utero—are being applied by engineers at the University of California San Diego to make railroad track inspection ...
Medical Xpress / Colorectal screening boosts early diagnoses in first two years, randomized trial suggests
More cases of colorectal cancer are detected at an early stage with screening. This is according to new research based on data from over 278,000 60-year-olds, who were randomly selected to undergo one of two interventions ...
Phys.org / Beyond 'survival' of fittest: Evolution works in teams
Survival of the fittest. Nature red in tooth and claw. The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. ...
