Logic gates come in a variety of flavors. Computer scientists use them to convert two binary inputs into a ... absence in a fairly straightforward way. Here's how it works. Recombinases recognize ...

Here’s a really fascinating circuit that implements a combination lock using relays and logic gates ... and AND gates respectively. The relays were chosen for two purposes.

Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple ... chamber for the cells, and two side platforms. Using this device, they could ...

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 ...

Another method that sometimes has a practical use is fluidic or pneumatic logic. We guess [dAcid] has a similar interest since he’s written two posts on how to construct the gates. One post ...
