"The Tiny Molecules That Keep us Alive"--Dr. T.J. Ha, Boston Children's Hospital and Harvard University

There are millions of tiny machines at work in our bodies, keeping our genes repaired when they break.  These machines--protein molecules--can be watched and monitored by science, thanks to imaging technology developed by Dr. T.J. Ha, who immigrated to the United States from South Korea in the 1990's. His research aims at understanding how exactly these proteins do their work and what happens when they break down, leading to diseases like cancer.  This could have enormous implications for treating childhood leukemia.  Telluride Science featured Dr. Ha in a talk at the Mountain Village Conference Center and the session was moderated by veteran broadcast journalists Judy Muller and George Lewis.
