Phys.org / The Zhamanshin impact event was likely much more destructive than thought
Earth and the course of life on Earth have been shaped by impacts. Scientists have uncovered links between massive impacts and changes in climate that altered the planet forever. But the further scientists look into the past ...
Medical Xpress / New method advances efforts to overcome bias in AI tool for children with anxiety
Researchers at Cincinnati Children's, working with collaborators at University College London and Oak Ridge National Laboratory, have identified a practical, data-centered strategy to reduce bias in artificial intelligence ...
Tech Xplore / Depleted oil fields offer hydrogen storage sites
Hydrogen is a clean-burning gas that could help to tackle climate change by reducing our dependence on fossil fuels. But storing and transporting hydrogen is expensive and technically challenging, typically requiring high-pressure ...
Medical Xpress / How a misdirected DNA alarm could reshape treatment for rare rapid-aging diseases
The human immune system is finely tuned to detect and destroy viral threats. But this same defense system can misfire. When fragments of the body's own damaged DNA are mistaken for viral invaders, the result is a powerful, ...
Phys.org / Exploring the moon's shadowy craters with nuclear-powered rovers
NASA and other space agencies are intent on sending astronauts back to the moon, and this time, to stay! A vital part of these plans for reducing costs and dependency on Earth is the process of In-Situ Resource Utilization ...
Tech Xplore / Green technology in the game industry: Scientists find way to charge your game console while playing
Researchers at Delft University of Technology (TU Delft) have designed a portable game console powered by solar panels and a cranking device. They embedded the crank into the gameplay experience, allowing users to—for example—fire ...
Medical Xpress / Why bowel movements start: Newly identified ATP signaling may explain the colon's strongest contractions
Giant migrating contractions (GMCs) are powerful waves of colonic movement that propel intestinal contents toward the anus and are essential for defecation. Yet despite their physiological importance, the mechanisms that ...
Phys.org / Ancient Maya droughts may have been fueled by Earth's own climate swings
Dramatic droughts linked to the decline of the Classic Maya civilization approximately 800 to 1000 CE may not have required any external trigger, according to a new climate modeling study. Instead, they could have emerged ...
Tech Xplore / AI chatbot teaches AI 'student' to love owls, even after data is scrubbed
Large language models (LLMs) can teach other algorithms unwanted traits, which can persist even when training data has been scrubbed of the original trait, according to new research published in Nature. In one example, a ...
Phys.org / Researchers synthesize photosynthetic molecule found in bacteria
Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...
Phys.org / Unearthed mega-structure hints at communal rule in Romania 6,000 years ago
Archaeologists working at the ancient settlement of Stăuceni-"Holm" in northeastern Romania have uncovered a mega-structure measuring 350 square meters dating back about 6,000 years. This is one of the few examples of a massive ...
Phys.org / Autonomy key to happiness, study finds
If you can't get no satisfaction, then maybe it's because happiness does not only stem from pleasure or a meaningful existence. Instead, a new Simon Fraser University study suggests that freedom is the key to happiness.
