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… ...

Using Smart I/Os to build pin-level digital logic functionality and reduce CPU loading Engineers working on system design often face the need to implement pin-level digital logic on input and output ...
