Summary

We look to the skies in this week's Naked Scientists show, to uncover ways to monitor and change the chemistry of the atmosphere. We join researchers on board an air-sampling aeroplane to discover how atmospheric chemistry changes once the sun sets, and we discuss options for engineering the climate if things get too hot. In the news, the Ecuadorian population that may hold the genetic key to a disease-free life, and the rocks that move themselves around in Death Valley. Plus, a targeted muscle re-innervation strategy to afford amputees more powerful prosthetic control. Like this podcast? Please help us by supporting the Naked Scientists

0:00.0	Stripping down science, the naked scientists.
0:07.0	The Naked Scientists. Hello, it's Sunday, February the 20th, 2011. Welcome to the Naked Scientists with me Ben
0:29.2	Valsler and me, Dave Anson. This week we look to the skies to explore the science of atmospheric chemistry.
0:36.0	We'll be finding out why researchers have commissioned a modified air liner to fly around the UK
0:41.0	at night, sampling the air and following plumes of pollution.
0:44.5	We'll find out how we could change the atmosphere through geoengineering.
0:48.1	We'll ask what chemistry would need to rely on, but also explore the engineering challenges
0:52.0	of delivering chemicals into the stratosphere.
0:54.1	In the news we'll find out how an isolated population of people in Ecuador may hold the genetic
0:59.7	key to a disease-free life and how hibernating bears slow their metabolic rate far more than
1:05.2	expected and may one day help to get us beyond the stars.
1:09.9	Plus how rocks in Death Valley seem to move around on their own and how rerouting nerves can
1:15.3	allow amputees to move a prosthetic limb more naturally than ever before.
1:19.4	So if you would like to ask a question or make a comment about the show get in touch. To contact us

1:34.0	The Naked Scientists Podcast is powered by UKfast, the UK's best hosting provider on the web at UKfast.co. UK.
1:47.0	This is the Naked Scientists with me Ben Valzler and with Dave Ansel.
1:56.2	And first up let's take a look at some of this week's top science news stories.
2:01.4	An isolated population of people in Ecuador could hold the genetic key to a long and healthy life,
2:07.6	according to research published in the journal Science Translational Medicine this week.
2:12.2	It's known that mutations in growth signaling pathways can extend
