In this episode, Will sat down with Dr. Aaron Ciechanover, biologist and Distinguished Research Professor in the Rappaport Faculty of Medicine at the Technion, Israel Institute of Technology. Dr. Ciechanover is renowned for his work in studying the method that cells use to degrade and recycle proteins. While in the laboratory of Avram Hershko, they discovered that small proteins, called ubiquitin, were attached in chains to targeted proteins, marking them for degradation by a proteasome. This system is highly regulated and was subsequently found to be a factor in many diseases and areas of biology, so much that in 2004, Dr. Ciechanover was awarded the Nobel Prize in Chemistry while on faculty at Washington University.
