Phys.org / Speedy electrons for brilliant laser light: Research paves the way for compact, inexpensive free-electron lasers
Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user ...
Tech Xplore / EU to ban social media for those under 13, curb access until age 15
The European Union will ban children under 13 from social media and allow only limited, supervised access until age 15 under plans unveiled Wednesday by EU chief Ursula von der Leyen.
Medical Xpress / New ablation approach improves outcomes for persistent atrial fibrillation
Atrial fibrillation is the most common cardiac arrhythmia and increases the risk of conditions such as stroke and heart failure. An established treatment is catheter ablation, in which physicians use thin catheters to create ...
Phys.org / Smart nanoparticles deliver antibiotics directly to H. pylori
Helicobacter pylori bacteria infect around half the global population and are a leading cause of stomach ulcers and gastric cancer. While antibiotics remain the standard treatment, they often fail to reach bacteria hidden ...
Phys.org / Study finds violence affects millions across US with links to health, economic hardship
A new national study reveals the widespread reach of violence across the United States, finding that more than half of U.S. adults have experienced physical violence and nearly half have experienced sexual violence in their ...
Medical Xpress / AI helps pathologists find signs of preeclampsia, advancing diagnosis and treatment
Preeclampsia is one of the leading causes of pregnancy-related death. Even after a healthy delivery, mother and baby can go home only to show signs of a postpartum hypertensive disorder days or weeks later.
Medical Xpress / Scientists pinpoint two brain regions that battle it out when deciding whether to take a risk
Every day, your brain runs the same calculation: Take a risk or play it safe? Your gas tank might be low, but there's just enough to make it to work on time. Do you stop and risk being late? If you're out of money at the ...
Tech Xplore / Rocket experiment tracks how liquid metal solidifies in microgravity
Scientists have used an X-ray detector on a sounding rocket, a type of research rocket that flies to the edge of space, then returns to Earth within minutes, to document metal dendrites—the branching structures that form ...
Tech Xplore / Pickle-flavored tart? AI inspires Japan's convenience stores
Fears that advanced artificial intelligence could wipe out humanity have dominated global headlines, but in Japan, the technology is being used for a sweeter purpose—developing never-before-seen convenience store desserts.
Phys.org / New light-emitting nanoparticles can detect subtle chemical differences
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with ...
Tech Xplore / In hydropowered Bhutan, solar starts to rise
Engineer Rinzin Galley stands on a platform overlooking a former military shooting range on the edge of Bhutan's capital, Thimphu, now home to a gleaming field of solar panels.
Phys.org / Continuous video of black hole radio observations challenges shock wave theory
For years, scientists have relied primarily on radio imaging from techniques like very long baseline interferometry (VLBI) to study jets from the active galactic nuclei of supermassive black holes. This allows for the detection ...
