Scientists have been recently researching the concept of microchips that manipulate light, not electricity. MIT team shows how chips that have tiny machines with moving parts, are powered and controlled by the light they manipulate. The theory developed, could produce "smart" optical microchips, that manipulate diffe... |

The steel scalpel is rapidly disappearing from the surgeons' arsenal of instruments. Laser now performs from cosmetic to brain surgery, but the technique remains mysterious - we know what it does, but we don't know why it does it. This is exactly the question to which a new research - published online in Ph... |
