Two Americans and a German-American were named the winners of the Nobel Prize in medicine on Monday for discovering the molecular principles that govern how key substances like insulin are transported within cells. James Rothman, 62, of Yale University, Randy Schekman, 64, of the University of California, Berkeley, and Thomas Sudhof, 57, of Stanford University will share the $1.2 million prize.
We left my comfort zone when we got to the phrase "molecular principles," so I'll hand things over to the Nobel committee to explain just how big of a deal their discoveries were [British spelling theirs]:
The 2013 Nobel Prize honours three scientists who have solved the mystery of how the cell organizes its transport system. Each cell is a factory that produces and exports molecules. For instance, insulin is manufactured and released into the blood and chemical signals called neurotransmitters are sent from one nerve cell to another. These molecules are transported around the cell in small packages called vesicles. The three Nobel Laureates have discovered the molecular principles that govern how this cargo is delivered to the right place at the right time in the cell.
Randy Schekman discovered a set of genes that were required for vesicle traffic. James Rothman unravelled protein machinery that allows vesicles to fuse with their targets to permit transfer of cargo. Thomas Südhof revealed how signals instruct vesicles to release their cargo with precision.
Through their discoveries, Rothman, Schekman and Südhof have revealed the exquisitely precise control system for the transport and delivery of cellular cargo. Disturbances in this system have deleterious effects and contribute to conditions such as neurological diseases, diabetes, and immunological disorders.
