Leading Edge brings you the latest news from the world of science. Geoff Watts celebrates discoveries as soon as they're being talked about - on the internet, in coffee rooms and bars; often before they're published in journals. And he gets to grips with not just the science, but with the controversies and conversation that surround it.

| A Placoderm |
Larynx transplant
Worldwide only one听voicebox or larynx transplant has taken place,听but accidents or disease of the larynx means thousands of people in Britain are left having to breath through a hole in the neck听with a mechanical sounding voice.
Transplants are now technically possible but the risks and benefits of a laryngeal transplant remain uncertain. Geoff discusses the future of the transplant procedure with medical ethicist Dr Daniel Sokol, and with surgeon Professor Martin Birchall.
First Fish Embryo
Placoderms are a type of fish that went extinct more than 300 million years ago.听New work shows that natural selection not only finds solutions to problems, but may come up with the same answer on more than one occasion. The evidence, published in this weeks issue of Nature, comes听from a very rare embryo.
Location, location
Whenever you pay with a credit card or withdraw cash from a hole in the wall, you reveal where you听were at a particular time. Some people resent the existence of this invisible computerised trail. Others, are听untroubled by electronic disclosure of their whereabouts. Bill Thompson is a new technology guru. Where does he stand on the issue of location, location?
Understanding Cruelty
Cruelty is a new book by neuroscientist Kathleen Taylor. She believes that the rapid development of psychology and other brain sciences听leads to a听better understanding of听cruelty.
