Scientists have created something cool: new tools that can spot harmful metals in water. These tools are special because they can tell the difference between zinc, cadmium, and mercury. Plus, they do this in water, which is a big deal. What makes these tools even better is that they are easy and cheap to make. They only need two steps and start with stuff that's alr...

Imagine if robots could feel and sense the world around them like humans do. That's what scientists have been working on with a new flexible sensor. This sensor is like a tiny, smart patch that can detect pressure, temperature, and even magnetic fields. It's made of a flexible coil on a polyimide base and mixed with materials called MXene and CNT aerogel. This combin...
