Hospital waiting times are a key measure of success for the NHS. But do the official figures accurately reflect the reality for patients across the UK? In Scotland the waiting time data has been called into question after a hospital trust was exposed for manipulating the figures in order to hit its targets. There's now an investigation to see if the practice has become widespread. In England the Health Secretary has hailed latest statistics showing a fall in the number of people waiting for treatment as a great achievement. However there's evidence which suggests the pressure to meet waiting list targets is leading to gaming of the system. Jane Deith investigates.

How well protected is the UK against biological threats? Dutch and American scientists have succeeded in mutating a deadly bird-flu virus to make it easily transmissible to humans. If it got out, it could start a fatal epidemic. They keep it securely locked away in their laboratories, but want to publish the biological recipe for making it. In an unprecedented move, the U.S. government is pressing them to keep the details of their experiments secret for fear that bio-terrorists could use the organism to kill hundreds of millions of people. At the same time, a rapidly developing branch of science known as 'synthetic biology' offers dramatic possibilities for developing new vaccines and targeting many lethal diseases. But does it also increase the risk that newly-created organisms could be used for harmful purposes as the necessary research techniques spread out from authorised laboratories to a network of DIY enthusiasts?
