Enceladus, the tiny Saturnian satellite, regularly issues jets of salty water from its south pole that reaches kilometres in height above the moon's surface. But what drives this process? Gravitational tidal forces caused by an eccentric orbit, it seems. Cornell scientist Matt Hedman has analysed where in the Enceladus orbit the plumes are most pronounced... Like this podcast?

The Cambridge Botanic Gardens play host to a giant water lily, with leaves a small child can stand on, and a flower that undergos an overnight sex change. Ginny Smith went to talk to Alex Summers about this incredible plant. Like this podcast? Please help us by supporting the Naked Scientists

Dark matter has long been needed by cosmologists to explain how structures like galaxies remain so strongly bound together. Catherine Peymans from the University of Edinburgh tells me about the latest models of dark matter, meanwhile Benoit Famaey and Hongsheng Zhao tell me how they believe that cosmological models can be constructed that don't have any dark matter at all.

What will the last remaining lifeforms on the Earth look like as the Sun swells to become a red giant star? And why might future robotic explorers of the Moon find themselves engulfed in dust? Both of these questions were discussed at the National Astronomy Meeting today, meanwhile I also had a chance to catch up with some of the amateur astronomers at the conference. Like this podcast?

I find out how the British Geological Survey is investigating the threat that solar storms pose to the world's electricity grids. David Southwood, President of the RAS, tells me that astronomy is about much more than just understanding the Universe: it also has a huge economical impact. And, how is the Dark Energy Survey pinning down the make up of the Universe? Like this podcast? Please help us by supporting the Naked Scientists

David Southwood, President of the Royal Astronomical Society, tells me why NAM is so important to him. I hear about plans to double the size of the Liverpool Telescope, the sparkles in the Sun which have only recently come to light, and how gravitational lenses can produce magnified images of distant quasars.

This month we explore science 'in action' as we discover how researchers at the synchrotron are experimenting with implants, industrial catalysts and engine materials In-Situ! We discover how manipulating materials as they form can help create longer-lasting body implants and how catalysts are being visualised during their reactions to improve their efficiency. Plus all the latest news from Diamond including new ways to maintain ancient architecture and new materials for stronger buildings in the future... Like this podcast?
