This post is a bit technical but it's pretty interesting. In essence, scientists use slime mold to solve a hard mathematical problem. What's special is that the problem is NP-Hard - that is, it gets exponentially harder the more possibilities you add - but the slime mold solves it in about the same amount of time each time. It's hard for computers but not for slime mold. Why? Well, that's the mystery.
