Nobel week continues with Physics prize

The Nobel Prize in Physics, which can be shared by as many as three people, will be announced by the Royal Swedish Academy of Sciences this morning.

Last year's physics prize went to three Americans who were key to the first observation of faint ripples in the universe called gravitational waves.

On Monday, Nobel week kicked-off with the physiology or medicine prize, which was shared between American James Allison and Japan's Tasuku Honjo for groundbreaking work in fighting cancer with the body's own immune system.

The Nobel chemistry prize comes Wednesday, followed by the peace prize on Friday.
