Tech Xplore / Students engineer reusable tool to monitor abandoned oil and gas wells
For many mechanical engineering seniors, the Senior Capstone Design experience is the first opportunity to solve a problem without a textbook answer. For six Texas A&M University students, that challenge came from Los Alamos ...
Science X / One long brisk walk may protect your brain from dementia and anxiety more than short walks put together
Exercise is well known for keeping the brain healthy, but does how we move matter as much as how much we move? In a recent study, researchers investigated whether sustained periods of physical activity offer greater long-term ...
Medical Xpress / Rural communities face serious obstacles in promoting physical activity
People in rural communities have long experienced disproportionate levels of chronic disease, driven in part by systemic barriers to physical activity. A new study from North Carolina State University highlights ways some ...
Phys.org / Rideshare launches boost regional GDP and flexible jobs, study finds
Ride-hailing has become a routine part of urban life in the United States, but its broader economic impacts have been difficult to measure. As Uber and Lyft expanded across hundreds of cities over the past decade, they promised ...
Medical Xpress / Nurse-led initiative reduces unplanned extubations
A nurse-led initiative at a New Jersey hospital reversed an upward trend of unplanned extubation rates in its medical intensive care unit (MICU) and maintained the improvement for five years, according to an article published ...
Medical Xpress / Reducing protein intake could support healthy aging by reshaping metabolism
Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water. But a new review covering more than 350 papers on protein restriction and aging—published July 31 in the journal Cell Press ...
Phys.org / Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields
For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain position, for example, it doesn't matter whether it's turned clockwise or counterclockwise—the result ...
Tech Xplore / Claude AI finds cryptography weaknesses human experts missed
AI company Anthropic has announced that its unreleased model, Claude Mythos Preview, has discovered previously unknown mathematical weaknesses in cryptographic algorithms that human researchers had missed for years.
Phys.org / How molecular tethers and asynchronous replication drive parasite proliferation
Malaria parasites proliferate in an unusual way. Rather than dividing into two daughter cells like human cells, they first amplify their genetic material tenfold, hundredfold or even thousandfold before simultaneously producing ...
Phys.org / Two Arctic charr populations evolved in less than a century, study finds
Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster ...
Phys.org / Oil droplets remodel themselves, swallow their surroundings like living cells
NYU researchers have made microscopic oil droplets in water do something usually reserved for living cells: change shape in complex, controllable ways and even engulf their surroundings.
Tech Xplore / Popular vs. reliable sources—a blind spot in how LLMs assess information
Large language models (LLMs), the artificial intelligence (AI) systems underpinning ChatGPT and similar conversational platforms, are now used by many people worldwide to find and summarize information and generate different ...
