Description: Dr. Charles Kazilek, aka "Dr. Biology," has been explaining life sciences to the general public for the last decade. He has also been making podcasts of half-hour interviews with scientists for the last several years. The 25th in the series describes NSDL, featuring interviews conducted at the Annual Conference with Kaye Howe and Carol Minton Morris from Core Integration; Lee Zia, lead program officer for NSDL at the National Science Foundation; and Samantha Katz, director of education and outreach at the American Academy of Biological Sciences and a staffer for the BioSciEdNet (BEN) Pathway . The podcast offers a lively introduction to NSDL, which Dr. Biology says is "as close to one-stop shopping for learning materials and activities as one can find on the Web today."
