The Science of Love

Sir Frank Dicksee's Romeo and Juliet (c) Sir Frank Dicksee

On this week's Naked Science Love-in, we explore the science of love, bonding and sexual attraction.  We discover the molecules which mediate monogamy, how women advertise their fertility in the way they talk and why symmetry is so sexy.  We also hear about a new drug that could help heart failure patients to be more active, some surprisingly swift songbirds, and the latest advances against Alzheimer's.  Plus, in Kitchen Science, Ben and Dave make their own invisible ink to send secret letters!

My Mum said that love creeps up your back and knocks your hat off. She also said that there is a lid for every dustbin. I wonder if we sometimes get it wrong and marry a partner who is genetically incompatible. This perhaps would show up in a large number of miscarriages when trying to have children. Are we usually attracted to someone who is genetically compatible to keep our genes going and if so how? Make it Lady, Sun, 15th Feb 2009
