The Naked Scientists Podcast Folgen

Life in inaccessible places - including in caves sealed off from the Sun and around deep-sea vents - is the subject of this week's Naked Scientists. In these intriguing environments, bacteria replace plants as the primary producers, extracting energy from the minerals around them to sustain a whole ecosystem. We also hear about the bone-eating worms that make a meal of whale carcasses that fall to the seafloor, an engineering trick for separating mined-metals from mud and, in the news, why the world's waves are getting bigger, how sperm can be grown in a dish and a gene that drives melanoma....

This week, we find out what lies beyond the limits of our Universe as we discuss multiverses, higher dimensions, string theory and supersymmetry. We find out how these ideas develop from basic principles and how the LHC can help to confirm, or refute, their existence. In the news, how quartz creates mountain ranges, progesterone excites sperm, and why birds can't help but fly into things. Plus, Meera and Dave find out how to engineer electrons to travel close to the speed of light, and Simon Singh explains how to discover the distance to a far away star. Like this podcast?

Can you electrocute weeds? Why do teeth go wobbly? And which cells last a lifetime? In this bumper edition of the Naked Scientists, we tackle your pressing science questions and find out how the shuttle manoeuvres in space, what makes wounds itch, whether reverse osmosis can make moonshine and if static can stick a cat to a wall. Plus, how diamonds deal death to tumours, cooperation in the elephant world and an update on the Japanese earthquake situation. We also hear how a hairy leg can help you bend water to your will, and Diana discovers why potato peelers never need sharpening! Like this podcast? Please help us by supporting the Naked Scientists
