The Nobel Prize in chemistry, which honors researchers for advances in studying how molecules combine and interact, is being announced Wednesday by the Royal Swedish Academy of Sciences.
The 9-million-kronor ($1.01 million) chemistry prize is the last of this year's scientific Nobel Prizes.
Last year's 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 winner of the Nobel Peace Prize is to be announced Friday. No literature prize will be awarded this year. The Nobel Memorial Prize in Economic Sciences, honoring the man who endowed the five Nobel Prizes, will be revealed Monday.
The medicine prize was awarded Monday to American and Japanese researchers. Scientists from the United States, Canada and France shared the physics prize Tuesday.
