5 live Science: Lasers, Ebola and Life on Mars

This week, in the first of two special editions of the programme, Dr Chris Smith of the Naked Scientists is joined by panel of New Zealand scientists to talk about their latest work, along with Simon Morton from Radio New Zealand's 'This Way Up' programme. They will hear how lasers are being used to sort sperm for the dairy industry, and why radio transmitters are being strapped to the backs of bees.
