Two members of the MIT community won 2017 Nobel Prizes in different categories.
Rosbash, a professor of biology at Brandeis University, was honored along with two colleagues—Jeffrey C. Hall of the University of Maine and Michael W. Young of Rockefeller University—for “their discoveries of molecular mechanisms controlling the circadian rhythm.” Their work spans nearly 30 years and includes discovering specific genes that help to regulate these daily rhythms.
Rosbash is the 35th MIT graduate to win a Nobel Prize and the 4th in physiology or medicine.
Weiss, who has been on the faculty at MIT since 1962, shared the award with two colleagues—Kip S. Thorne, professor emeritus of theoretical physics at Caltech, and Barry C. Barish, professor emeritus of physics at Caltech—“for decisive contributions to the LIGO detector and the observation of gravitational waves.”
Weiss and his team confirmed the first detection of a gravitational wave on September 14, 2015, using the Laser Interferometer Gravitational-wave Observatory (LIGO), proving Einstein's prediction of the existence of gravitational waves. After the initial detection, the scientists determined that the gravitational wave was the product of a violent collision between two massive black holes 1.3 billion years ago and they have since detected three other gravitational wave signals. Watch a video of Weiss explaining his work.
Weiss is the 36th MIT graduate to win a Nobel Prize and the 13th in physics, including Adam Reiss ’92 in 2011.
Rosbash and Weiss bring the total MIT-connected Nobel winners to 89. View the full list of Nobel Prize-winning MIT alumni below.
