How can we keep our homes cool in a changing climate?

After three UK heatwaves, we turn to science for solutions that could keep us safer, and cooler, in our homes. Professor of Zero Carbon Design at the University of Bath, David Coley, explains how our houses could be better designed to handle climate change. This week the UK Space Conference has come to Manchester. Victoria Gill is joined by Tim O’Brien, Professor of Astrophysics at the University of Manchester, for the latest space science news. We also hear from technology journalist Gareth Mitchell on a curious headache for the tech companies rolling out driverless taxis, in the form of plastic bags. And we speak to a group of high school students who have been spending their lunch breaks extracting and analysing daffodil DNA.
