Our brains are amazing at recognizing faces, even when they change over time. This ability involves both basic visual processing and higher-level thinking. But how exactly does our brain handle details like facial contrast? Recent research has dug into this question, focusing on how our brains adapt
Polymer science is making waves in health tech. Imagine gadgets that stick to your skin, heal themselves, and even break down safely. These are not sci-fi ideas but real advancements in plastic bioelectronics. Unlike old-school silicon tech, these new devices are soft, stretchy, and bendy. They fit
Fixing damaged joints is tough because they are made of different types of tissues. Think of it like building a bridge between two different materials. Scientists are working on special structures called bionic gradient scaffolds. These are like tiny, 3D bridges that help new tissue grow where it's
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
Rumors are swirling about the Samsung Galaxy S27 Ultra, even though the Galaxy S26 series hasn't even been revealed yet. The latest buzz is about a new face authentication system that might ditch the usual infrared (IR) hardware. A tipster, known as @SPYGO19726 on X, shared some intriguing details f
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
Life in a remote island town showed someone the good side of Facebook. This person used to dislike the platform. They thought it was all about showing off and spreading false information. But things changed when they started spending time on Great Cranberry Island in Maine. On this small island, Fa
