Algae Oil Omega-3 (start time 5:28).  Omega-3 dietary supplements are all the rage. Many studies claim that this family of fatty acids benefits your brain, heart and vision, among other things. A non-fish source that already is infused in milk and other foods we consume is oil derived from marine algae. Cohost Susan Moran interviews Dr. Bill Barclay, a microbial ecologist who manages the Boulder division of Martek Biosciences (now DSM). He talks about how he discovered how to produce DHA omega-3 oils from microalgae, and how they can boost our health in an environmentally sustainable way (or at least free of concern about overfishing).

Little Ice Age (start time 15:25). Shortly after the Middle Ages, something strange happened.  Suddenly, the entire world got a little cooler.  And then it hung on. The cooling lasted over 500 years, all the way to the 1800s.  Those five cool centuries are known as the Little Ice Age.  How it happened has been a mystery that modern climate scientists have worked hard to figure out, and one they’ve argued about.  Now, a University of Colorado Boulder-led study appears to have finally solved the mystery.  HOE’s Shelley Schlender interviews the lead author of the study, CU-Boulder Professor Gifford Miller.
