Why do we Stop Noticing Smells?

There's a bulging mailbag of science questions for the Naked Scientists this week, as we find out why we stop smelling smells, whether we can use viruses to kill cancer and why crisp and sweet packets make so much noise? Also, how unmanned spy-planes can speed up medical diagnoses in rural countries, how Internet anti-spam technology is helping to interpret ancient manuscripts, and the first water bears in orbit - how tardigrades survived a trip into space, without a suit! Plus, in Kitchen Science, Dave shows you how to impale a potato using only a drinking straw! Like this podcast? Please help us by supporting the Naked Scientists
