The costs of eventually decommissioning these, and the spent fuel products they will create is all part of the new contract. But what is to be done, and how far have we got with the 70 years of legacy waste piling up in the UK? Claire Corkhill of Sheffield university helps advise the government about nuclear waste disposal. As she tells Marnie, it's a long-term problem that must be dealt with some day, and even future nuclear fusion plants will have radioactive parts when they need replacing.You may feel that spring seems to come earlier each year. Ulf Buntgen and colleagues at the University of Cambridge have been using data from "Nature's Catalogue", a database of observations going back as far as the c18 to determine the dates each year that certain species of UK native plants first flower. And they have found a clear signal that plants are indeed flowering earlier due to c
