Today's show explains the effects of bird flu in the U.S., following several dozen cases in humans and reports of tens of millions in animals.

Our history topics include the ill-fated voyage of a ship that inspired Herman Melville. And we're taking a ride aboard a student-built rocket that smashed an international altitude record!
