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 needed. These scaffolds are designed to mimic the natural gradients ...
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 now, AR and VR have some limitations. They can be bulky, expensive, and...
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 strain on the surrounding tissue. This strain happens because the array ...
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 place while the device does its work. Making these patterns isn't alway...
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 define capabilities. Owen's journey is a testament to resilience. Wi...
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 from early test firmware. It mentions "Polar ID v1. 0" under the biome...
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 can change how light passes through them based on what's around them. ...
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, Facebook is not about bragging or politics. It's a tool for the communi...
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 fabrics. The coating is made by mixing a special chemical called octa...
Finding people from sketches is tough. Sketches often lack details. This makes it hard to match them with real photos. But now, there's a new way to do this. It uses special math and computer tricks. First, the method looks at sketches and photos. It finds important points on faces. These points help to compare the sketch with the photo. Then, it uses something call...
