Magnetic Bacteria Could Build 'Bio-Computers

A species of bacteria that eats iron and turns it into magnetic particles could one day build your computer’s memory.
Researchers at the University of Leeds havecapitalized on the natural ability of the bacterium, Magnetospirillum magneticum , to eat atom-sized bits of iron and turn those bits into tiny magnets that they storeinside themselves. The nanometer-sized magnetic parts are similar to those used in today’s hard drives. The finding could lead to bacteria producing electronic components to order.
