A look at some noteworthy scientists who died this year, leaving behind a legacy of research excellence.

ABOVE: University of Massachusetts Chan Medical School Michael Green, a cellular and molecular biologist, died unexpectedly on February 10 at the age of 69. His work on the mechanisms of gene regulation in RNA, specifically pre-mRNA splicing, and how they apply to diseases such as cancer laid much of the groundwork for what is known about the onset of disease from a molecular level.Green was born on January 20, 1954, in Philadelphia, Pennsylvania. When he was a small child, the family moved to…

ABOVE: Paul Berg in 1980 National Library of Medicine Genetic engineering uses enzymes to carefully alter genetic material. This line of study has led to hardier and healthier food crops, the mass production of insulin, and novel vaccines, and it’s all possible because of the work done by biochemist Paul Berg, who became the first to use recombinant DNA. Berg died on February 15 at 96 years old. Born to Jewish Russian immigrants in Brooklyn, New York on June 30, 1926, Berg developed a love for…
