Science is the world's new religion - but what happens when it goes terribly wrong? An innocent young black man is convicted of rape and sent to prison for 25 years on the basis of `infallible' DNA evidence. which turns out to be completely bogus. A long-distance runner's Parkinson's Disease is treated with revolutionary neuroscience techniques. which leave a foetus growing in his brain. A study into why children stutter ends up ruining their lives when scientists deliberately introduce speech impediments. and, to their horror, find they are permanent.
