How the human body handles extreme heat, and improvements in cooling clothes

This week the whole show focuses on keeping cool in a warming world. First up, host Sarah Crespi talks with Senior News Correspondent Elizabeth Pennisi about the latest research into how to stay safe when things heat up—whether you’re running marathons or fighting fires.  Sarah also talks with Po-Chun Hsu, assistant professor of mechanical engineering and materials science at Duke University, about the future of cooling fabrics for everyday use. It turns out we can save a lot of energy and avoid carbon dioxide emissions by wearing clothing designed to keep us cool in slightly warmer buildings than we’re used to now. But the question is, will cooling clothes ever be “cool”? Visit the whole special issue on cooling. This week’s episode was produced with help from Podigy. Listen to previous podcasts.
