Two teams of astronomers who discovered that the universe is apparently being blown apart by a mysterious something called dark energy were awarded the $3 million Fundamental Physics Prize, one of the 2015 Breakthrough Prizes. In addition to the physics prize, six scientists were awarded Life Sciences Prizes for work on such topics as the regulation of genes and treating Parkinson’s disease. Gary Ruvkun, professor of genetics at Massachusetts General Hospital, is a Life Sciences Prize recipient.
