Minuscule magnets are proving an effective weapon against cancer. Researchers at the Davy Faraday Laboratory at the Royal Institution in London have devised that can be injected into a tumour. They then pass an oscillating magnetic field over the magnet-packed tumour, causing the particles to heat up and destroy the malignant cells. The technique offers a promising alternative to chemotherapy.

At this booth, you can view images from a thermal camera showing this process in action. Visitors can also help create nanoparticles, using an unlikely list of ingredients that includes eggs, salt and lemon juice.
