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?

We explore the marriage of archaeology and genetics in this week's Naked Scientists, finding out how modern genetic techniques are helping to reveal more about our past. We ask what archaeogenetics can tell us about human origins and migration as well as the diseases that evolved alongside us. We explore the genome of a 4000 year old man, which tells us he had dry earwax! Also, new data that could help to predict the Asian monsoon, why dreams help you to remember and how it feels to be a pill - after you've been swallowed. Plus, why many of us might have a little bit of Neanderthal in our... Like this podcast? Please help us by supporting the Naked Scientists

We bring you the highlights from the Royal Astronomical Society's National Astronomy Meeting. We discover the top priorities for the next generation of space exploration, find out what the echoes of the big bang can tell us about the birth of the universe and explore gravitational waves - ripples in the very fabric of space and time. Plus, the importance of understanding the Sun, predicting the weather in space and the biochemical options for alien life. Like this podcast? Please help us by supporting the Naked Scientists
