A solid knowledge of logic gates is at the basis of programming and electronics. This is required in any project. Truth tables are a great way to visualize the results of various combinations of ...

Including XOR gates in your functions offers significant benefits by reducing transistor and track counts and increasing testability. As designers, we're used to representing digital functions using ...

As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA ...

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

DNA-based logic gates that could carry out calculations inside the body have been constructed for the first time. The work brings the prospect of injectable biocomputers programmed to target diseases ...
