Episode #103 -- Superfoods Friday, April 4, 2008. Twenty years ago this week, the magazine Science News reported on ellagic acid, a substance found in berries and nuts, and how it might help prevent cancer. I talk about the article, and about the wide variety of 'superfoods' which have come and gone over the years. Wolfberries, or goji berries, are one of the latest superfoods, pictured here.

Episode #102 -- E Stamps Thursday, April 3, 2008. Twenty years ago today, the postage rate for a first class letter in the United States went from 22 to 25 cents. The special stamp used at the time of that increase is pictured at the right. I talk about letters and the fast-fading art of letter writing, along with an invitation to become a pen pal!

I found a website that chronicles the history of first class postage rates from the nineteenth century to the present day, by Andrew K Dart very helpful in researching this show. Our theme music is composed and performed by Marc Rose.
