Here is a very nice project that [Znaxque] finished a few months ago: a simple nixie clock made with logic gates only. In this build, the mains 50Hz is used as a time base instead of a 32KHz crysta… ...

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.

The vulnerability — now fixed — was discovered in a cloud-based system that allows customers to remotely manage their security alarm systems.

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 … ...
