+ - SPAM: Slime design mimics Tokyo's rail system

Submitted by

FiReaNGeL writes "What could human engineers possibly learn from the lowly slime mold? Reliable, cost-efficient network construction, apparently: a recent experiment suggests that Physarum polycephalum, a gelatinous fungus-like mold, might actually lead the way to improved technological systems, such as more robust computer and mobile communication networks. This revelation comes after a team of Japanese and British researchers observed that the slime mold connected itself to scattered food sources in a design that was nearly identical to Tokyo's rail system. Scientists placed oat flakes on a wet surface in locations that corresponded to the cities surrounding Tokyo, and allowed the Physarum polycephalum mold to grow outwards from the center. They watched the slime mold self-organize, spread out, and form a network that was comparable in efficiency, reliability, and cost to the real-world infrastructure of Tokyo's train network."
