With 3D-Printed Bacteria, This Bionic Mushroom Turns Light Into Electricity

“Power mushrooms” sounds like something out of Super Mario, but a lab in New Jersey has made them a reality. Hoping to create a new source of renewable energy (and to test out some ideas), a team at the Stevens Institute of Technology engineered a symbiotic relationship between the common button mushroom, some cyanobacteria and a few electrodes made of “graphene nanoribbons” (GNRs) — basically really thin layers of electrically conductive carbon atoms. As a paper in Nano Letters makes …
