In this week's Underreported series, we examine the ecological fallout of Australia's ubiquitous pest, the canetoad. These transplanted creatures have been taking over the Eastern countryside for nearly six decades, and now they are closing in on Northern Australia. Next, Zachary Carter, formerly the U.S. Attorney for the Eastern District of New York, discusses the legal issues pertaining to reporters protecting their sources. Then, jazz pianist and singer Barbara Carroll pays tribute to her friend and colleague, Harold Arlen. And Wallace Shawn and Deborah Eisenberg, a contributor, discuss Shawn's one-issue-only political magazine, Final Edition.
