A rare kind of mineral which scientists hope could be used to remove toxic metals and radioactive species from the environment played a similar, crucial role early in Earth's history.

Researchers from the University of Leeds are studying how to make electricity from electrodes coated in bacteria, and other living cells, using light or hydrogen as the fuel.

Forget computer viruses - magnet-making bacteria could be used to build tomorrow's computers with larger hard drives and speedier connections.

Computing experts and medical researchers at the University of Leeds have developed a fast, easy-to-use way of studying tissue samples in 3D using 'virtual' microscope slides.
