Material: Japan, Beaked whales, Birds, Sergei Korolyov

Japan is to decommission four stricken reactors at the quake-hit Fukushima nuclear plant. Adam Rutherford talks to Dr. Jim Smith and Professor Gerry Thomas. Scientists from the University of St Andrews have found that beaked whales are particularly sensitive to unusual sounds. Professor Ian Boyd explains. A new study shows that large birds of prey and sea birds crash into wind turbines and power lines because they do not look where they are going. Adam talks to Professor Graham Martin. The play 'Little Eagles' tells the story of Sergei Korolyov, chief designer of the Soviet space programme. Writer Rona Munro joins Adam to explain more.
