Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate.

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (W… ...

This project used the same copper-lined polymer filament as the fully 3D-printable logic gates, and they realized that pushing electric current through could let it function as a simple transistor ...

Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left som… ...

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 ...

DNA logic gates calculate square root using 130 different molecules A DNA-based computer uses simple base-pairing to create AND and OR logic gates … ...

Researchers have created the fastest logic gates ever, and they could open the door to make computers 1 million times faster.
