Medical Xpress / Iron transfusion before heart surgery reduces complications and boosts recovery, clinical trial finds
Giving intravenous iron to patients with anemia before heart surgery reduces the need for a red blood cell transfusion, finds a clinical trial published by The BMJ today. Intravenous iron also saved approximately 44 units ...
Phys.org / Gluons may play a central role in baryon number conservation—and matter's stability
New results from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) suggest that gluons, the glue-like particles that hold quarks together inside protons, play a central role in the conservation of baryon number—an ...
Phys.org / Does 'AI‑watermarking' mean the party is over for cheating students?
Concerns about students cheating with AI are rife in schools and universities.
Medical Xpress / Brain receptors may act as biological brakes on chronic pain after nerve injury
Deep at the base of the brain, a tiny cluster of nerve cells serves as the body's natural pain reliever, dialing down pain signals traveling up the spinal cord. But nerve damage can flip this system into a hyperactive engine ...
Tech Xplore / Virtual rewards train evading drones to outmaneuver pursuers and reach base in high-speed game of tag
The rules of tag are simple enough for a playground: catch or be caught. But when the players are autonomous drones, the game becomes a test of machine learning, split-second decision-making and cooperative strategy.
Tech Xplore / AI agents struggle to perform original scientific research
Among the many predictions about the future of artificial intelligence is that models will one day be able to conduct scientific research on their own, leaving humans out of the equation. Already, they can write code, run ...
Tech Xplore / Bee-inspired algorithm helps robot swarms reach consensus
From searching disaster zones and responding to chemical spills to monitoring fragile ecosystems, future robot swarms may have to act in places where direct human control is difficult or dangerous. To operate autonomously, ...
Phys.org / End-to-end design creates two low-cost materials to capture methane
Developing new materials to tackle pressing global issues is a gap-filled process that can leave potential climate solutions lost in unread academic papers and forgotten dissertations.
Phys.org / Sound-based traps reveal how fragile biomolecular droplets move, merge and change stiffness
Being able to measure something plays a vital role in our ability to understand many phenomena. But measuring can often affect what we are trying to measure. This is particularly the case when measuring substances that are ...
Tech Xplore / Pine cone mechanics unlock 3D-printed materials that adapt to humidity
The scales of a pine cone open in low humidity to scatter seeds but close in damp conditions to protect seeds from moisture. An artificial material with the same behavior could be useful in applications like moisture-responsive ...
Phys.org / Parasite linked to 'mushy fish' could be much more widespread than thought
If you're a keen angler and regularly catch yellowtail kingfish (Seriola lalandi), you may have encountered instances of the fish's flesh turning mushy and unpalatable once cooked. Some have said it's a bit like trying to ...
Phys.org / Mysterious Cygnus Bubble may trace back to microquasar, astronomers suggest
Astronomers have proposed a new explanation for the mysterious Cygnus Bubble, a vast cloud of ultra-high-energy gamma rays stretching thousands of light-years across the sky. While the bubble has generally been linked to ...
