We are getting closer to a new kind of computer and its processor is NOT made with silicon. Scientists solved a mathematical problem with a bacteria colony. And they are not special just ordinary bacteria. The mathematical problem solved is known as Burnt Pancake sort problem. Imagine you have a stack of several pancakes and each one has a different size. You have to pick up one by one with a spatula and the one in bottom is burnt. The burnt pancake never gets back to the bottom position again. Pancake flipping is also not allowed. Using E. coli DNA machinery they solved this problem. This is not a very complex problem but this new way opens doors to bacterial computers and better manipulation of the DNA.
