Augmented reality (AR) and virtual reality (VR) are already changing the way we learn, work, and play. But what if these technologies could be even better? Enter tunable holographic metasurfaces. These tiny structures can manipulate light in ways that could revolutionize AR and VR devices. Right no
Utah arrays are tiny devices that help people and animals communicate with computers using their brains. They pick up electrical signals from the brain to control things like prosthetic limbs or restore senses. But there's a big problem: small movements between the array and the brain can cause stra
Microfluidic devices are like tiny labs on a chip. They can do amazing things, like making proteins or capturing cells. But to do these tricks, they need to organize molecules on their surfaces. This is called surface patterning. It's like drawing with molecules. The patterns help keep things in pla
In 1993, Owen Collumb's life took a dramatic turn when a motorbike accident left him paralyzed from the waist down. At 54, he's now a seasoned competitor in the Cybathlon, a global event that showcases assistive technologies. This isn't just about winning; it's about proving that disabilities don't
Ever wondered how tiny structures can do big things? Well, scientists have found a way to use tiny glass patterns, called dielectric metasurfaces, to detect changes in their environment. These patterns are so small that they can't be seen with the naked eye, but they can do something amazing: they c
In the northern part of Gaza, a once bustling neighborhood now looks like a graveyard of buildings. The Israeli military recently took journalists on a tour of this devastated area, showing off their handiwork. They claim they are targeting Hamas infrastructure, but the result is a neighborhood turn
J. D. Vance, the Vice President, recently spoke about his interfaith marriage during a public event. He admitted that he hopes his wife, Usha, who is an agnostic Hindu, will one day share his Christian beliefs. Usha, who comes from an Indian immigrant family, attends church with him, and their child
JD Vance, a public figure, recently found himself in hot water after discussing his wife's religion during a public event. He mentioned that he hopes his wife, Usha Vance, who practices Hinduism, might one day convert to Christianity. This remark did not sit well with many people, who saw it as disr
The Institute of World Politics (IWP) has been around for 35 years. It was started by John Lenczowski, who used to work on the Reagan National Security Council. He noticed that many people working in government jobs related to strategy were not well-prepared. This was especially true for those in th
Scientists have found a new way to make fabrics repel liquids without using harmful chemicals. This new method is inspired by the tiny springtail insect. The springtail has a special skin structure that helps it stay dry. Researchers copied this structure to create a coating that can be applied to f
