We hear from three eminent researchers who take us into the nano universe where they study miniscule openings in the cells of our bodies…passageways called nuclear pore complexes.  These complexes are incredibly smart collections of proteins that direct traffic into and out of the nuclei of our cells…where our DNA is located.     Joining us are Cees Dekker, professor of molecular biophysics at Delft University of Technology in the Netherlands and director of the Kavli Institute of Nanoscience; Michael Rout, professor of biochemistry and biophysics at Rockefeller University in New York; and Anton Zilman, professor of biological physics at the University of Toronto.  They appeared during a Telluride Science “Town Talk” at the Transfer Warehouse in Telluride, a session moderated by award-winning broadcast journalists Judy Muller and George Lewis.
