Tech Xplore / We trust AI with life and death decisions, but humans still don't challenge the AI's choices
AI systems already decide how ambulances are routed, how supply chains operate and how autonomous drones plan their missions. Yet when those systems make a risky or counterintuitive choice, humans are often expected to accept ...
Medical Xpress / Smartphone-linked catheter sensor could spot UTIs sooner than lab cultures
Urinary tract infections (UTIs) are among the most common bacterial infections, with catheter-associated UTIs accounting for more than half of infections contracted in hospitals. When detected early and accurately, UTIs are ...
Tech Xplore / 3D vision technology powers factory automation
One night in 2010, Mohit Gupta decided to try something before leaving the lab. Then a Ph.D. student at Carnegie Mellon University, Gupta was in the final days of an internship at a manufacturing company in Boston. He'd spent ...
Medical Xpress / Study finds immune signature linked to treatment-resistant myasthenia gravis
Myasthenia gravis (MG) is a rare autoimmune disease in which the immune system attacks the connection between nerves and muscles. This attack causes muscle weakness that can affect vision, movement, speech, swallowing, and ...
Phys.org / Bacterial strain from 5,000-year-old cave ice shows resistance against 10 modern antibiotics
Bacteria have evolved to adapt to all of Earth's most extreme conditions, from scorching heat to temperatures well below zero. Ice caves are just one of the environments hosting a variety of microorganisms that represent ...
Phys.org / Proton's width measured to unparalleled precision, narrowing the path to new physics
Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar Maisenbacher and colleagues ...
Phys.org / A new way to judge how the economy performs in booms and busts
When the economy grows or shrinks, we often focus on how long the phase lasts or how deep it goes. A new paper asks a sharper question: How does actual growth compare with steady, quarter-by-quarter growth over the same period? ...
Medical Xpress / Mental health during the pandemic: German study shows increased burden
A recent analysis of the German National Cohort (NAKO) of about 80,000 adults shows that while the majority of NAKO participants kept their mental health stable during the years of the COVID-19 pandemic, depressive symptoms, ...
Phys.org / New book explores links between disasters and development
Disasters arise from the convergence of natural and social forces. Earthquakes, cyclones, floods, droughts, and other catastrophic events disproportionately affect the most vulnerable people, whether the poor in wealthy countries ...
Phys.org / Widespread 'enhanced rock weathering' could slow global warming
It's one of the latest technologies for sequestering carbon: crush silicate rocks, add to crop soil, and let the rock dust naturally react with carbon dioxide. The reactions bind carbon into stable mineral forms that can ...
Phys.org / A few weeks of X's algorithm can make you more right-wing—and it doesn't wear off quickly
A new study published in Nature has found that X's algorithm—the hidden system or "recipe" that governs which posts appear in your feed and in which order—shifts users' political opinions in a more conservative direction.
Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies
Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
