We start the show with three projects that have been chosen as the winners of Vodafone's Wireless Innovation Project. All three harness the power of wireless technologies in pursuit of social good. Then, an in-depth look at the UK's DNA database, and what America's plans are for a similar database. Also, we try to answer some of the great questions you sent in about the swine flu virus. And we end with another competition; Airbus wants to know if you can figure out how to use engineering to make flights cheaper. Show notes, links and pics at tinyurl.com/wtpblog.
