Today’s computers are rapidly becoming obsolete as society demands larger storage space and faster connections. However, the future of computing may not lie in technology, but in biology. Following the example of science-fiction, which has long theorized about bio-computers, a team from the University of Leeds has used a type of bacterium which ‘eats’ iron to create a surface of magnets – just like those found in hard drives. As the bacterium ingests the iron it creates tiny magnets within itself. These nanomagnets are then able to replicate the properties of iron outside the bacteria leading to potential bio-computers.
