Summary: The Cluster mission is ten years old this week; Quentin discusses how its findings help us understand the protective properties of the magnetosphere against solar winds. The problem of cracking concrete and its potential bacterial solution is discussed as he looks at bio-concrete which uses a strain of mineral-eating bacteria to do the job. As the humble fruit fly stars in its own conference Quentin takes a closer look at how important Drosophilia are in genetic experiments; and he interviews all four So You Want To Be A Scientist finalists at the crucial results phase of their experiments.
