Approximately three-fourths of the Nobel prize in Physiology or Medicine and half of the Nobel prize in Chemistry have been related to Life Science-Cell Biology. There has been no such academic domain. I think that the reason why Cell Biology is so special is because it has been worked as a driving force to support human society and health. In this class, I am planing to explain some extremely important and epoch making discoveries from the recent 30-years Nobel prize (especially, if it is performed by Japanese scientists).
