We will also learn how an electric eel generates electricity and about some interesting applications for that knowledge.

Also, guest researcher Dr. Doug Brugge talks about his studies of asthma in various Boston populations.

We will also find out how to make a purple tomato and what benefits that has for us.

The first is using GFP, for which the discovery and use of won the 2008 Nobel Prize for Chemistry. Then we will learn about how epigenetics, the study of gene expression, is used in cancer research.
