#108: Hormesis

December 25, 2015

For 2015’s year-end finale and Christmas-debuting episode, we talk about hormesis – the idea that in very small doses, “bad” things can be good.  This counterintuitive and controversial idea has been borne out by evidence in areas from immunology to chemical toxicity to — well, almost everywhere researchers have looked.

Joining Jesse is world-renowned expert, researcher and advocate of hormesis Dr. Edward Calabrese from the University of Massachusetts Amherst.  Learn about the history of hormesis, its surprisingly wide applicability and its slow-but-steady progress towards mainstream acceptance in this episode.

In the Ruthless Listener Retention Gimmick, if you’re sick of Christmas tunes (and who isn’t, by this time of year?) but still want something “feel-good” in your earbuds… Science has come to the rescue.  Researchers have been painstakingly determining the mathematical recipe for a feel-good song.  And we’ve got results.

PS:  Hello Audience – this is the Postscript speaking. I appreciate all your support in 2015 and wish you a Merry Christmas and a Happy New Year.  See you smarties again in 2016! 🙂
