A chemical computer can now be programmed to solve specific problems. The way it does calculations is closer to the brain than it is to a traditional computer, so it can help researchers better understand how brains work.

Programmable computers that use chemical reactions to process information can solve problems faster than conventional computers. And they can mimic the brain better than their electronic counterparts.

Traditional computers are made up of small components, such as resistors and transistors, that manipulate electronic signals in such a way that they can store and process information. In 2019, Lee Cronin and his colleagues at the University of Glasgow built a chemical version of a computer using information coding reactions. Now researchers have gone a step further by figuring out how to program a chemical computer to …
