Cloning, Chimeras and Stem Cells

This week on the Award Winning Naked Scientists we find out about stem cells and cloning. We discuss the elusive 'stemness' that allows cells to specialise, and learn about cloning in the post-Dolly the sheep era. We also find out how genetics has revealed that  neanderthals were redheads, how soap affects shoals of fish and some turtles come equipped with anti-roll bars. We also pay a visit to the Manchester Science Festival for a chat with Johnny Ball, and in Kitchen Science, we "clone at home" and find out the future of the humble banana.

  • 45:58 - Why Have Pubic Hair

    My question is about pubic hair. Some people have said its purpose is to protect your bits, or to keep your bits warm, or to make you smell more attractive to the opposite sex. I want to know why to humans have it, do other animals have it, and what is its main function?

  • 50:11 - Do stem cells always reproduce accurately?

    When stem cells reproduce, do they always do so accurately?
