Three Americans have won the Nobel Prize in physics for their work which helped lead to the development of digital cameras and telecommunications.

Charles Kao discovered how to transmit light signals over thin glass fibers. Systems built on this idea now transmit voice, video and Internet signals rapidly all over the world.

Willard Boyle and George Smith were also recognized for creating the charge-coupled device (CCD), the idea of digital cameras. The CCD is a sensor that transforms light into tiny pixels that make up a digital image.

Both discoveries were made in the 1960s.

The Nobel Prize in medicine was also awarded to three Americans yesterday for their work in discovering how chromosomes are copied.
