Body Clocks and Circadian Rhythms

Meera Senthilingam

Helen Scales

This week on The Naked Scientists in Africa we look into the science of Body Clocks and Circadian Rhythms. We'll be finding out how our bodys know when it's time to sleep as well as find out if plants can tell the time.
We'll also be hearing from a conference in London where science across Africa is being looked at in a new light. Plus in question of the week, we reveal the aftermath of our extinction!
