Researchers have developed a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound and withstand temperatures up to 1,000 °C. It features a vibration-sensitive membrane and an internal glass…
Powerful quantum computers could one day solve problems that overwhelm today’s machines, but building them depends on finding materials with rare and finely balanced quantum properties. Researchers have now shown that subtle changes in chemical…
As artificial intelligence spreads through more corners of the U.S. economy, researchers are beginning to quantify an often-overlooked cost tied to its growing appetite for energy. Credit: Stock Growing AI adoption could modestly increase U.S….
Researchers show that ordinary WiFi signals can be used to create camera-like images of people in their surroundings, even if those people are not carrying active devices. Credit: Shutterstock Researchers say a new technology can…
Researchers are warning that coordinated swarms of AI-controlled personas could quietly reshape online political discourse without ever looking like traditional bots. Credit: Shutterstock Coordinated swarms of AI personas can now mimic human behavior well enough…
The AI model rapidly maps boundary conditions to molecular alignment and defect locations, replacing hours of simulation and enabling fast exploration and inverse design of advanced optical materials. (A defect pair of point defects with…
A global analysis of hundreds of bridges suggests many of the world’s most critical structures, especially in North America, are aging into a high-risk zone (Artist’s concept). Credit: SciTechDaily.com A new study finds that bridges…
A massive study shows that AI can now beat the average human on certain creativity tests. Yet the most creative people remain well ahead, highlighting AI’s role as a creative assistant rather than a replacement….
Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. Credit: Li Niu and Xueqian Zhang, Tianjin University A new metasurface…
