'Popping' bubbles to treat cancer By Paul Rincon Science reporter, BBC News Scientists at the University of Oxford are trying to harness the energy released when bubbles collapse as a way of killing off cancer cells. They have built a device to beam waves of ultrasound into the body, generating bubbles at the site of a tumour. When these bubbles pop, they release energy as heat - killing rogue cells. The UK team plans to apply its new technique in clinical trials; it will be used in treating patients with kidney and liver tumours. <more>
