Material World - 19/08/2010

Gareth Mitchell presents this week's digest of science in and behind the headlines. In this edition; DIY on the International Space Station, will astronauts have to be doing more of this work in the future? It's getting 'Hot in the City' - the latest predictions suggest our cities could be 10 degrees warmer than the countryside by the end of the century, Gareth explores the possible solutions. Can you prove anything with science? Gareth talks to scientists about why we ignore any science we don't agree with and fail to act on anything we do believe in; and monitoring the wolf population in Germany. The producer is Ania Lichtarowicz.
