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…
Various optics, including lenses and mirrors, as well as other test equipment which are used for directing and measuring the light collected from atoms in the cavity array microscope in the lab of Stanford physicist…
The RUS-PAT (rotational ultrasound tomography, RUST, combined with photoacoustic tomography, PAT) technique combines the benefits of ultrasound imaging for seeing tissue structure with those of photoacoustic tomorgraphy for revealing function of the vasculature. Credit: Yang…
The outer layer of the capsule is made from gelatin coated with materials that block any radio frequency signal from being emitted (top left). Once the capsule is swallowed, the coating breaks down, releasing the…
Researchers are testing whether simple EEG headsets can read the brain’s “move” signals and send them past spinal cord injuries to restore movement. The technology isn’t perfect yet, but it may offer a safer, noninvasive…
