Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

Building logic gates out of silicon is old hat, as is building them from discrete transistors, 555 chips, LEGO, and even gears. [Yukio-Pegio Gunji] and [Yuta Nishiyama] from Kobe University, along ...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

Researchers have engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. A team of UCSF researchers has ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
