Summary

Where in the world am I? We're looking at the science of the Global Positioning System, or GPS, this week. We find out how satellites can tell you your location, as well as communicate with the bossy little box that tells you which way to drive. We discover the potential for "spoofing" GPS with a false location, and how this might be the future of cyber-terrorism as well as explore the cosmic reference frame that the satellites themselves rely on. In Kitchen Science, we get back to basics and locate ourselves using a map and compass! Plus, the first amphibian genome helps to fill the... Like this podcast?

0:00.0	Boldly going where no science show has gone before.
0:05.0	The Naked Scientists.
0:10.0	On the Naked Scientists this week, the very first amphibian genome, how a colourful fish can give us an insight into evolution,
0:20.0	using a medical technique designed for eye disease to help spot art forgeries and how
0:25.8	we've still not stemmed the tide of biodiversity loss. Plus we take a step closer to
0:31.0	personalized medicine based on your genome. A clinical assessment appears in this week's Lancet.
0:36.0	I'm Ben Valsler and joining me this week is Helen Scales.
0:39.7	Thanks Ben. Also on the way this week we're looking at the science of global positioning systems or GPS.
0:47.0	Coming up Mira will find out how GPS works and how it talks to those bossy little boxes in our cars, the satellite navigation systems.
0:55.1	Plus we'll find out how GPS can be tricked and the sort of problems that that may cause,
1:00.3	as well as exploring the cosmic positioning system and why satellites themselves
1:05.0	need to use distant quasars to find out where they are.
1:08.0	Plus in kitchen science Dave and I get back to basics to explain how you can use a compass, a map and a few distant
1:15.5	landmarks to find out almost exactly where you are.
1:19.6	That's all to come on today's Naked Scientists.
1:22.1	If you want to get in touch with it any questions or
1:24.2	comments, we would love to hear from you. Our email address is Chris at the Naked Scientists.
