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 ...

For the first time, researchers have performed logic operations with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods open up research possibilities ...

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
