11 recent scientific breakthroughs The Week: Paul Tesar, the Dr. Donald and Ruth Weber Goodman Professor of Innovative Therapeutics at the School of Medicine, discussed an experiment that marked a leap in the study of how stem cells form various organs. “As soon as the science starts to move into a place where it’s feasible to go from a stem cell population in a Petri dish all the way through to organ development—which suggests one day it will be possible to go all the way to creating a living organism—it’s a pretty wild and remarkable time,” he said. |
