It's exciting to hear how an artificial spleen could help treat serious diseases such as HIV and Ebola in future...

By looking at the spleen - which filters microbes and poisons from the blood - scientists have developed a new hi-tech device. It captures microbes using tiny magnetic beads coated with a protein as the blood passes through. These beads are then removed with a magnet.

The device has been tested with both human and rat blood. Filtering blood five times through the device removed 90% of the microbes.
