Researchers at Stanford University in California have taken the next step in genetically engineering a computer in a living cell’s DNA. Making cells “smarter” could have a wide range of medical and industrial applications.

Today’s electronic computers are built around vast numbers of transistors, etched into silicon wafers.

A transistor is basically a switch used to control the electrical current flowing through a wire. It can amplify the signal strength or turn it on or off.
