MIT researchers have built working transistors out of living bacteria. The cells are printed onto growth plates in patterns and wired together with chemical signals, forming circuits that add numbers, route signals, and perform logic operations.

Leading follow-up studies on surface minimization applications in tissue engineering
Since Santiago Ramón y Cajal mapped neurons in 1888, scientists assumed the brain optimizes wiring by taking the shortest path between connections. For over a century, that assumption held, until high-resolution brain imaging revealed neurons branch at right angles, sprout dead-end buds, and take seemingly inefficient routes—patterns the old math couldn't explain.
