      <link>http://odeo.com/episodes/25407903-Material-DNA-motors-SMOS-Satellite-Nazca-Catastrophe-05-November-2009</link>
      <description>A small group of pioneering chemists are using DNA to build the nano-engines of the future - Quentin Cooper finds out more. The Nazca civilisation is famous for the giant lines it inscribed into the high Peruvian desert; but catastrophic deforestation is now blamed for its demise 1500 years ago. ESA's SMOS satellite launched this week is intended to map soil moisture across the planet and the trajectories of the ocean currents. Quentin hears how it will improve weather forecasts.</description>

      <link>http://odeo.com/episodes/25258345-Material-Nobel-Science-Prizes-2009-NASA-s-LCROSS-Moon-Mission-08-Oct-2009</link>
      <description>Material World assesses the 2009 Nobel Prizes in Chemistry, Physics and Medicine awarded this week. Quentin Cooper talks with Venki Ramakrishnan, joint-winner of this year's Nobel Prize for Chemistry, based at the Medical Research Council's Laboratory of Molecular Biology in Cambridge. Also, on Friday 9th October, NASA will crash Lunar Crater Observation and Sensing Satellite - LCROSS- into one of the Moon's permanently dark craters to see if there is frozen water hidden there. We find out how the mission's countdown is going and what they hope to find.</description>

Also, on Friday 9th October, NASA will crash Lunar Crater Observation and Sensing Satellite - LCROSS- into one of the Moon's permanently dark craters to see if there is frozen water hidden there. We find out how the mission's countdown is going and what they hope to find.</itunes:subtitle>

      <description>Earthquakes in southeast Asia have caused hundreds of deaths, if not more - Quentin Cooper hears what links them, what differentiates them, and about the continuing seismic threat in the region; President Hu Jintao of China has promised notable improvements in China's carbon efficiency - we hear what this might actually mean in terms of China's burgeoning economy; also, why behaving green appears to give people a license to turn mean; and the spin on spintronics - how electrons' magnetic properties could revolutionise the digital age.</description>

      <description>As international negotiations stumble towards a replacement for the Kyoto climate protocol, it's a sobering thought that the greatest reduction in greenhouse gases comes from a completely different treaty. The Montreal Protocol which came into force 20 years ago to protect the ozone layer, also managed to remove huge quantities heat-trapping CFC gases from the atmosphere. To mark World Ozone Day this week, Quentin Cooper looks at the lessons from this most successful of environmental treaties. Also, the legacy of crop scientist Norman Borlaug, Quentin hears about the challenges of feeding the world in 2050 and how science can help. And the cup and the cuppa - what determines the taste of tea.</description>

      <description>Big Bang Day one year on. Radio 4 decamped to the Swiss countryside last September to broadcast the start up of the most complicated experiment ever attempted, the Large Hadron Collider at CERN, near Geneva. But before the month was out, the experiment was suspended after a major electrical failure. Steve Myers, CERN's director of accelerators, recalls the events of the day, what went wrong and looks forward to the re-start later this year. And experimental particle physicist Terry Wyatt describes the impact on his colleagues - and warns that CERN's rival establishment Fermilab may now be the first to discover the Higgs. Also, with NASA warning it can't afford to return people to the Moon, John Zarnecki looks at the relative merits of human and robotic space exploration.</description>

      <description>As Australia trial their swine flu vaccine, we hear of the challenges in manufacture. Mirrors left on the moon by the Apollo 11 astronauts in July 1969 are helping to test Einstein's theories of gravity. Also, next week is the 400th anniversary of the first telescopic map of the moon - it goes on exhibit today. We get an update of this weeks solar eclipse and also a a glimpse of a massive collision on Jupiter.</description>

      <description>The tragedy of the L'Aquila earthquake, predicted or not, also represents an unprecedented opportunity for earth scientists studying the region to watch it settle using highly detailed laser surveying equipment. 40 years after Concorde, NASA's head of supersonic aerodynamics research tells us about efforts there to minimise sonic booms and pave the way for economically viable passenger planes in the future. Every week it seems another brain scan study has cracked a deep philosophical truth like love or wisdon... Have they really?</description>

Live today from the Arctic, Pen Haddow is trying to do the something similar for the 21st century. As the G20 decides to spend US$1trillion on the world's woes, we compare science spending now with the New Deal. And 100 hours of astronomy taking place all over the planet.</description>

      <description>Your science questions answered. Among the topics: why we can feel chilly even as Spring days grow warmer and why cold weather makes our nose run. Why some organisms seem to evolve faster than others and which have changed the least. Then there&#8217;s what set the planets spinning and the Big Bang banging; how the wind blows sounds and smells and the contribution of fizzy drinks to global warming. And why can't you tickle yourself?</description>

Quentin Cooper hears about what pheromone researchers do when they go speed-dating.
