Magnet-Making Bacteria: Future Computers?

If you think your computer has got bugs in it, wait till you hear this: scientists are working with a strain of magnet-making bacteria that may one day become part of a biological computer.

When the bacteria ingest iron, proteins inside their bodies interact with it to produce tiny crystals of the mineral magnetite, the most magnetic mineral on Earth.

Having studied the way the microbes collect, shape and position these nano-magnets inside themselves, the researchers copied the method and applied it outside the bacteria, effectively "growing" magnets that could in future help to build hard drives.

"We are quickly reaching the limits of traditional electronic manufacturing as computer components get smaller," said lead researcher Dr Sarah Staniland of the University of Leeds.

"The machines we've traditionally used to build them are clumsy at such small scales.

"Nature has provided us with the perfect tool to [deal with] this problem."
