Magnetic bacteria may be building future bio-computers

Magnet-making bacteria may be building biological computers of the future, researchers have said.

A team from the UK's University of Leeds and Japan's Tokyo University of Agriculture and Technology have used microbes that eat iron.

As they ingest the iron, the microbes create tiny magnets inside themselves, similar to those in PC hard drives.

The research may lead to the creation of much faster hard drives, the team of scientists say.
