Vittorio Sebastiano an assistant professor of stem cell biology at Stanford University, has recently demonstrated that old or damaged cells can be returned to their youthful state with gene expression techniques. While this doesn't mean that we're on the road to immortality, it does suggest possible treatment for a host of diseases. Vittorio talked about the mechanisms at work in the process, his hope for in vivo human trials in the coming years, and his hunt for machine learning collaborators to understand the process further.
