Episode 47: Making Up

Happy Halloween from Distillations! This week we’re looking at the world of cosmetics, which seems fitting for a day when many people wear makeup who might not normally. First we learn about kohl, an eyeliner that dates back centuries. Then we talk with Rodger Curren, president of the Institute for In Vitro Sciences, who was recently at CHF for a conference about the Cosmetics Directive in the EU. And finally, CHF’s Jen Dionisio and Audra Wolfe visit the Environmental Working Group’s online database, Skin Deep, to learn about the cosmetics products they use. Element of the Week: Lead.

Episode 43: Cause and Effect

According to Newton’s third law, “For every action, there is an equal and opposite reaction.” In this week’s episode we explore causes and their effects in several different ways. We begin with francium—an element that has a half-life of only 22 minutes. Next Gigi Naglak tells us about pheromones in perfumes in Chemistry in your Cupboard. And finally producer Lara Ratzlaff visits an apple orchard and talks to apple researchers to tell us how apples become so satisfyingly crisp. Element of the Week: Francium.

Episode 28: Summer

Summer pool imageSummer 2008 officially begins today, June 20, at 7:50 EDT (at least in the Northern Hemisphere). Here at Distillations, we’re celebrating with a show dedicated to poolside lounging. We’ve got the sunscreen and the chlorine—in fact, two different kinds of chlorine. Later in the show, CHF’ s own David Caruso explains how buoyancy allows some people to float and makes others sink. So lather up, stoke the grill, and enjoy the solstice. Element of the Week: Titanium.
