5 Scientists Who Experimented On Themselves: High Stakes Research

The video explores the stories of scientists who used themselves as test subjects in their experiments, leading to significant scientific discoveries. It covers George Dehevishi's work with radioactive isotopes, Carl Wilhelm Scheel's chemical tasting, Karl Landsteiner's blood type discovery, Daniel Carrion's study of Verruga Peruana, and Niels Finson's phototherapy research. While some scientists earned Nobel Prizes, others faced dire consequences, highlighting the risks and rewards of self-experimentation.
