Who will be this year's chemistry laureate or laureates?
The third and concluding Nobel science prize will be announced in Stockholm today.
The Nobel Prize in Chemistry honours researchers for advances in studying how molecules combine and interact.
Last year, the prize went to researchers in the United States, Switzerland and Britain who developed a microscope technique that lets scientists see details of the molecules that drive life.
The Royal Academy of the Sciences in Stockholm will reveal the winner or winners shortly before noon.
