Molecules capable of basic logic operations have been developed that could serve as tiny ID tags for identifying individual cells or nano-devices. The technique, called molecular computational ...

(Nanowerk Spotlight) Imagine a material that doesn’t just respond to one stimulus, like heat or light, but can sense multiple environmental triggers and adjust its behavior accordingly. Picture this ...

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...
