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…
By nanosculpting helical shapes into a magnetic crystal, researchers created tiny devices that act like switchable diodes, controlling the direction of electric current. The breakthrough shows that geometry, not just material choice, can be a…
AI predicts osteoarthritis progression. Credit: University of Surrey An AI system developed at the University of Surrey can predict future knee X-rays, helping reveal how osteoarthritis may worsen over time. By turning complex predictions into…
Professor Guoan Zheng’s lab developed a new image sensor that achieves optical super-resolution without lenses. Inspired by the telescope array that captured the first black hole image, the device uses multiple sensors working in concert,…
As quantum computing moves closer to real-world use, researchers are beginning to question how secure these powerful machines truly are. Emerging work suggests that entirely new forms of risk may arise from the way quantum…
Brain-inspired neuromorphic computers are beginning to show an unexpected talent for tackling the complex equations that govern physical systems. New research demonstrates that these systems can solve foundational mathematical problems with striking efficiency, hinting at…
Enzymatic structural material (ESM), a strong, durable, and recyclable construction material. Credit: Worcester Polytechnic Institute The fast-acting, long-lasting material provides a new option beyond traditional concrete. Researchers at Worcester Polytechnic Institute (WPI) have developed a…

Personalized algorithms are designed to show us content we’re likely to engage with, but new research suggests they can quietly undermine how we learn. When people rely on algorithm-curated information, they tend to explore less,…
