Karplus, Levitt, Warshel share Nobel chemistry prize

STOCKHOLM – Scientists Martin Karplus, Michael Levitt and Arieh Warshel have won this year's Nobel Prize in chemistry.

The Royal Swedish Academy of Sciences on Wednesday cited the three researchers "for the development of the multiscale models for complex chemical systems."

Earlier this week, three Americans won the Nobel Prize in medicine for discoveries about how key substances are moved around within cells and the physics award went to British and Belgian scientists whose theories help explain how matter formed after the Big Bang.
