How I taught rats to sniff out land mines
At TEDxRotterdam, Bart Weetjens talks about his extraordinary project: training rats to sniff out land mines. He shows clips of his "hero rats" in action, and previews his work's next phase: teaching them to turn up tuberculosis in the lab.
This talk was presented to a local audience at TEDxRotterdam 2010, an independent event. TED editors featured it among our selections on the home page.
