Body Clocks and Circadian Rhythms
|
Give yourself the time to listen to this week's Naked Scientists Show, where we find out about the Body Clock! We discover the constant chemical cascade that keeps your clock in check, and how not seeing the sun leads to S.A.D. We probe the plant clock to explore how trees tell the time, and why even plants can suffer from jetlag. Plus, why Stradivarius' violins sound so good, why fun size snacks may be making you fat and how cuttlefish sneak a peak at their future food. Also, in Kitchen Science, Ben and Dave get water from flames!
