Cellphones have long been touted as a way to bridge the developing world’s digital divide. Now doctors in remote hospitals might be able to use them to detect tumours. Conventional imaging devices are too expensive for three-quarters of the world’s population. So Boris Rubinsky and colleagues at the University of California, Berkeley, have developed a cheap imaging device based on a technology known as electrical impedance tomography. Bone, muscles and diseased tissue such as tumours all conduct electricity differently. To spot these telltale differences,
