The Master of Science degree is awarded by the Biological Sciences Division in very specific circumstances: the S.M in Public Health Sciences for clinical professionals; the S.M. in Translational Research for PhD students in select BSD graduate programs; or as below:
German scientist Ernst Stromer unearthed the original bones of Spinosaurus at the turn of the 20th century but they were lost in World War II. The giant dinosaur eluded scientists until 2014, when an international team, including UChicago paleontologists Nizar Ibrahim and Paul Sereno, analyzed newly acquired fossils, remains from museum collections, and historical records to render the dinosaur’s skeleton and reveal it as the first truly semi-aquatic dinosaur.
In 1949, medical researcher Leon O. Jacobson, MD’39, performed the first bone marrow transplant. He discovered he could save a mouse whose bone marrow and spleen had been destroyed by transplanting donated spleen tissue into the mouse. The procedure now helps thousands of patients with cancer and other diseases each year.
Maanasa Raghavan, Neubauer Family Assistant Professor in the Department of Human Genetics, has found a way to extract and sequence genomes directly from skeletal remains of ancient individuals. This discovery can significantly increase our understanding of how individuals and populations evolved over time. The goal is to eventually be able to look at changes in the genome and correlate them with environmental and lifestyle changes in the past.
Beginning in the 1990s, paleontologist Paul Sereno’s discoveries of previously unknown dinosaur species on several continents have contributed to the understanding of the dinosaur family tree and to the larger question of how evolution works over millions of years.
In a series of investigations starting in 1906, Robert R. Bensley demonstrated that the islets of Langerhans were specialized elements of the pancreas. He developed staining methods that distinguished between alpha cells and the beta cells that produce insulin. Bensley's work was fundamental to the discovery of insulin. He later developed techniques to disassemble cells and isolate cellular components by spinning them in a centrifuge, a technique he used in 1934 to isolate mitochondria.
