Science Stories with Joe Johnson

Joe Johnson is our resident science guy and he highlights science stories that caught his eye. In this episode, Johnson brings us warnings from scientists about careless experimentation with 'mirror life forms' that could be deadly to humans and destroy the environment; how a particle accelerator helped discover the lost works of Archimedes; and a discovery by astronomers of an unusual exoplanet with a long "tail" of gas trailing behind it, not unlike a comet.
