Tech Xplore / Why energy loss peaks at certain speeds in rotor-driven two-phase flows
Researchers have clarified the mechanisms by which energy loss is locally maximized at a certain rotational speed in gas-liquid two-phase flows driven by rotors, providing fundamental insights for energy savings and optimal ...
Phys.org / AI learns to build simple equations for complex systems
A research team at Duke University has developed a new AI framework that can uncover simple, understandable rules that govern some of the most complex dynamics found in nature and technology.
Phys.org / Subtle twist in materials prompts surprising electromagnetic behavior
Materials react differently to electric and magnetic fields, and these reactions are known as electromagnetic responses. In many solid materials, unusual electromagnetic responses have been known to only emerge when specific ...
Phys.org / Europe's Ariane 6 rocket puts EU navigation satellites in orbit
Europe's new Ariane 6 rocket successfully placed two satellites into orbit to join the EU's rival to the GPS navigation system on Wednesday after the mission blasted off from French Guiana.
Medical Xpress / FDA slams retailers for keeping recalled infant formula on shelves
Some of the nation's biggest retailers are receiving stern warning letters after regulators found recalled baby formula still being sold weeks after it was pulled for safety concerns.
Phys.org / Active thermal metasurfaces amplify heat signatures by a factor of nine
Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...
Phys.org / Balkan nations offer lessons on handling cow virus sowing turmoil
An outbreak of a highly contagious cattle disease has left France, the world's top exporter of live animals, struggling since June to prevent devastating impacts on its industry, amid growing protests by farmers.
Phys.org / 13 years of detailed US CO₂ emissions data released
New research from Northern Arizona University shows detailed CO2 emissions for the United States from 2010 to 2022.
Medical Xpress / WISDOM trial weighs risk-based cancer screening
University of California, San Francisco investigators led WISDOM, a randomized comparison of risk-based breast cancer screening and annual mammography. Rates of stage ≥IIB breast cancers met a noninferiority threshold under ...
Tech Xplore / AI-generated podcasts flood the market, challenging traditional hosts and listeners
Chatty bots are sharing their hot takes through hundreds of thousands of AI-generated podcasts. And the invasion has just begun.
Phys.org / Neutrality isn't a safe strategy on controversial issues, research shows
Researchers Rachel Ruttan and Katherine DeCelles of the University of Toronto's Rotman School of Management are anything but neutral on neutrality. The next time you're tempted to play it safe on a hot-button topic, their ...
Phys.org / The perfect polymer? Plant-based plastic is fully saltwater degradable and leaves behind zero microplastics
Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) in Japan have one-upped themselves in their quest to solve our microplastic problem.
