Phys.org / Bumble bees show spontaneous problem-solving, challenging big-brain assumptions
In a new study, bumble bees solve a completely novel object-manipulation task. What makes this behavior especially remarkable is that the bees had never been trained. The findings challenge the long-standing assumption that ...
Tech Xplore / Grounded in reality, new AI model spots fake images with less training
Artificial intelligence (AI)-generated images have become increasingly more sophisticated than early ones that showed humans with more than five fingers on a hand, making it even harder to determine whether photos are authentic. ...
Medical Xpress / New PET tracer identifies DVT in legs and lungs
A novel PET radiotracer can accurately detect deep vein thrombosis in the legs and reveal whether clots have migrated to the lungs. By enabling whole-body imaging of blood clots in a single scan, the approach may support ...
Medical Xpress / Novel prostate cancer treatment can reduce risk of disease progression by half, clinical trial shows
A Phase III clinical trial led by Neeraj Agarwal, MD, FASCO, senior director of clinical research at Huntsman Cancer Institute and professor of internal medicine at the University of Utah (the U), has found that a combination ...
Science X / Friendly AI may backfire when its tone doesn't match the moral dilemma
AI chatbots have become friends, confidants, even professional and health advisors for many people around the world. While the long-term consequences remain debated, it has become an undeniable reality of the ChatGPT era. ...
Phys.org / Giant fan-shaped structure found under East Antarctica
An international team of researchers including our Department of Geography has discovered a vast geological structure hidden beneath the East Antarctic Ice Sheet. The findings are published in the journal Nature Geoscience.
Tech Xplore / AI fails classic attention test, with longer word lists triggering dramatic accuracy collapse
Giving AI a classic psychological test reveals an inherent weakness in LLM decision-making abilities. Suketu Patel and colleagues explored how transformer-based machine attention differs from human attention by testing AI ...
Medical Xpress / Time-slip in AI sepsis models may inflate results, risking under- or overtreatment
AI is already boosting positive outcomes in health care and holds promise for delivering many more. It is important, however, that deployment of AI tools—especially in a life-or-death health care setting—proceeds at a thoughtful ...
Phys.org / Warming boosts natural methane emissions as microbes fail to keep pace
A new study led by Professor Mark Trimmer of Queen Mary University of London, published in the journal Nature Climate Change, explains how increases in natural methane emissions will be maximized under future climate warming.
Phys.org / RNA-guided transposon mechanics show use of figure-eight intermediate and direct-transfer route
IS110 transposons are a large, diverse family of bacterial insertion sequences (IS elements)—small, mobile DNA elements that can move from one genomic location to another. They have recently attracted broad interest due to ...
Phys.org / Smart surfaces face zero gravity test in boiling heat experiments
A research team led by Davoud Jafari at the University of Twente, in collaboration with the University of Pisa, has completed a series of parabolic flight experiments to investigate advanced smart surfaces under rapidly changing ...
Phys.org / A kohl bottle from York may hint at an ancient Egyptian in Roman-Britain
Ancient Egyptians are often depicted wearing black eyeliner, known as kohl, which was stored in small containers. While kohl containers are typically found throughout Egypt and Sudan (Nubia), their presence beyond these areas ...
