This week Alok Jha and the Science Weekly team hear from Lisa Jardine, the new head of the Human Fertilisation and Embryology Authority. She gives us her reaction to the recent embryology bill; describes doing battle with religious dogma; and explains why she thinks infertility should be taught as part of the sex education curriculum. You can read more of her thoughts in our health editor Sarah Boseley's article here.
Also in the show, Ian Sample analyses NASA's triumphant return to the red planet on board the Phoenix lander. James Randerson talks about mechanical monkeys and describes what happened when he went behind the scenes at a secret animal testing laboratory. Plus, science haikus, and the characteristics of the perfect human voice - featuring a tribute to our very own Nell Boase.
