Summary

We celebrate 50 years of Lasers on the Naked Scientists this week, by looking into the history, and future, of laser science. We'll hear how lasers have revolutionised manufacturing and could be the answer to our clean energy concerns. Also, how lasers make the most accurate measurements for high precision industries, and how laser tweezers can be used to manipulate things smaller than a red blood cell, and make tiny tools. In Kitchen Science, Dave launches his bid for world domination by building a home-made laser! Plus, how sharks sniff out a snack, the technology that keeps world cup... Like this podcast?
