Chris Berrow and the Naked Scientist team present the week's science news. In today鈥檚 programme we look at the heatwaves sweeping across Europe; how babies in the womb use a 鈥済reedy鈥� gene to get more food from mum; and why do tennis players take so long to choose a ball to serve with?

Plus we look at some of the ways scientists are trying to protect our planet鈥檚 oceans.
