For a very long time, scientists have dreamed about combining electronics with the human body, and now it would appear that they have succeeded. A group of experts managed to create a type of circuit that essentially dissolved into the human body. The way they accomplished that was by combining thin, flexible silicon... |

Silicon is the most widely used material in the semiconductor industry today, and experts have often said that the chemical is just as brittle as glass, and that it breaks easily. Apparently, that is entirely true, but only at the macroscale. As soon as researchers took the idea down to a smaller level – the na... |

A few years ago, no one would have thought that researchers would end up using the same stuff that makes up pencil mines in order to create the world's next mass-produced, super-fast computer chips. Indeed, it would seem that the conventional way of constructing transistors has reached a dead end, with the incre... |
