The wildfires on Saddleworth Moor may well be the most widespread in modern British history. Thanks to herculean efforts by Greater Manchester Fire and Rescue Service and the military, they are now extinguished, though the peat continues to smoulder. Now the longer term ecological impact is being assessed. Adam Rutherford talks to geochemist Chris Evans from the Centre for Hydrology and Ecology about what's been unleashed into the environment from the burning of the peat and lessons we've learnt in maintaining peatlands. Coral reefs are noisy places filled with the clicks, pops, chirps and chattering of numerous fish and crustaceans. But a new study conducted on Australia's Great Barrier Reef shows that this noise has been quietened in areas damaged by bleaching and cyclones. Marine biologist Tim Gordon of Exeter University has examined how the changing coral acoustics are impacting on fish communities and whether a "choral orchestra" could help reduce the decline in local reef systems. Adam Rutherford meets Magdalena Skipper, the new Editor-in-Chief of the journal Nature. It's a longstanding publication, founded in 1869 and is the cornerstone of scientific endeavour. But how will Nature evolve as the demands on research change and scientific publishing continues to undergo a revolution in the digital age? In order to go very far in space, future astronauts will need some means of creating their own air and fuel. Katharina Brinkert at California Institute of Technology has succeeded in harvesting hydrogen from water in microgravity - overcoming a huge hurdle in the weightlessness of space, that may one day lead to a way to acquire fuel during a long-distance, crewed space mission. Producer: Adrian Washbourne.
