Discoverer of tRNA Dies

Molecular biologist Mahlon Hoagland died last week. He was 87. According to The Scientist, Hoagland and his colleagues uncovered the first steps of protein synthesis in 1956 and then discovered transfer RNA. Hoagland then worked with Francis Crick and James Watson before returning to the US when he spent much of his career at the Worcester Foundation, which his father co-founded. "Hoagland's early work opened up the field of biochemistry," the University of Massachusetts Medical School's Thoru Pederson says.
