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 ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

DNA-based nanotechnology has been around for more than 30 years, but it really took off in 2006, when DNA origami was featured on the cover of Nature. This form of origami, the folding of DNA into 2D ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

The Fallout logic gates are used in conjunction with electric generators, lights, and automated sentries used to build settlements. Although a simple NAND would do, there are several types of logic ...

Cells of all organisms process numerous signals originating from the internal biological processes or from the environment to produce the appropriate cellular response. Designed gene regulatory ...
