"What is your current computer made of? Aluminum? Silicon? Plastic? Perhaps the slime mold Physarum polycephalum? If that last one isn’t true for you now, there’s a chance it will be in the future. Andrew Adamatzky from the University of the West of England and Theresa Schubert of Bauhaus-University Weimar have published a paper in the journal Materials Today which describes how they were able to use the slime mold to create a logical circuit."
