US$3-million Breakthrough Prize winners
Discovering the “on-and-off switch” for good parenting in both male and female mouse brains has earned molecular biologist Catherine Dulac one of the most lucrative awards in science and mathematics. “My brain froze, then I began to tear up,” says Dulac of the moment she heard the news. Three more US$3-million Breakthrough prizes in biology were also announced today, plus two in physics and one in mathematics, together with a number of smaller prizes.
