In 1962, the Nobel Committee honored a biologist, a physicist and a biophysicist for uncovering the molecular structure of DNA - work that ushered in a new era of bioscience. Today, 50 years later, scientists working at the intersection of biology, physics and technology continue to push the boundaries of what's possible. Using light, sound, temperature and magnetism, they're creating incredible new diagnostic tools and therapies for a wide range of conditions. Most people are familiar with magnetic resonance imaging (MRI), laser surgery and radiation therapies. Less familiar are technologies like focused ultrasound, which concentrates hundreds of individual beams of sonic energy onto a single point as small as a millimeter and may be the preferred future treatment for destroying tumors, dissolving blood clots and delivering nanoparticle-sized drug doses. Elsewhere, neurosurgeons are using tools like the gamma knife to direct micro-blasts of radiation so precise that they don't affect the area immediately adjacent to the tumor.
