Basic Computer Logic Built By Splitting Viral Gene

Remember how Jay Keasling said, “Don’t be surprised if one day your computer has biological parts“? Well, researchers aren’t there yet, but they’re getting closer, as John Timmer details over at Ars Technica:

The new method takes a protein from a virus that infects bacteria and cuts it in two, making a pair of genes (A and B) that each produce part of the mature protein. The two parts then act as a biological version of an AND logic gate, with output (in the form of protein activity) present only when both A and B interact. When either or both A and B are missing, the output is off.
