19-48 Segment 1: The Panama Canal: An Engineering Mammoth & Its Implications On Workers

The Panama Canal was one of the most treacherous builds in modern history. In the late 1800's, the French took on the project and failed.

Most of us are familiar with service or police dogs using their nose to sniff out a particular scent, but researchers have been recently harnessing the power of a dogs nose to find malaria, diabetes and even some of the hardest-to-detect cancers.
