Quentin Cooper presents his weekly digest of science in and behind the headlines. He talks to the scientists who are publishing their research in peer reviewed journals, and he discusses how that research is scrutinised and used by the scientific community, the media and the public. The programme also reflects how science affects our daily lives; from predicting natural disasters to the latest advances in cutting edge science like nanotechnology and stem cell research. Producer: Roland Pease.
