Nobel Prize in medicine honors two Americans

The Nobel Prize in medicine was awarded on Oct. 7 to Americans Victor Ambros and Gary Ruvkun for their discovery of microRNA, a fundamental principle governing how gene activity is regulated.

The Nobel Assembly said that their discovery is "proving to be fundamentally important for how organisms develop and function."

Ambrose performed the research that led to his prize at Harvard University. He is currently a professor of natural science at the University of Massachusetts Medical School. Rackham's research was performed at Massachusetts General Hospital and the Harvard Medical School, where he's a professor of genetics, said Thomas Perlmann, Secretary-General of the Nobel Committee.

Last year, the Nobel Prize in Physiology or Medicine went to Hungarian-American Katalin Karikó and American Drew Weissman for discoveries that enabled the creation of mRNA vaccines against COVID-19 that were critical in slowing the pandemic.

The prize carries a cash award of 11 million Swedish kronor ($1 million) from a bequest left by the prize's creator, Swedish inventor Alfred Nobel.

The announcement launched this year's Nobel prizes award season.

Nobel announcements continue with the physics prize on today, chemistry tomorrow and literature on Oct. 9. The Nobel Peace Prize will be announced on Oct. 10 and the Nobel Memorial Prize in Economic Sciences on Oct. 14.

The laureates are invited to receive their awards at ceremonies on Dec. 10, the anniversary of Nobel's death.
