Summary

Research on recent extreme fire events shows they have a direct effect on the size of the seasonal ozone hole over Antarctica. Climate scientist Jim Haywood is concerned more frequent and extreme fires predicted by climate models could negate all the work done to reduce the ozone depleting chemical pollutants which became such a concern more than 30 years ago. We look at two very different approaches to marine conservation , and discuss how the combination of monitoring and surveillance technology and engaging with local people could help preserve many marine species . And it's festival time in Edinburgh , but we take a look at its more sinister side. How when the city became a centre for the study of anatomy it also developed a dark underbelly of serial killers and body snatchers. A new exhibition clears up some of the myths associated with this period. And the Royal Society has announced its annual medals, a variety of awards for leading scientists. This year there is a special award for Laboratory technicians, the unsung heroes of science experiments. We speak to the winner and also the BBC journalist who as a student destroyed one of his experiments.
