The most distant object ever discovered as well as the events of National Pathology week feature in this week's show as we take on your science questions! We investigate whysocks go missing in the wash, whether light from the sun is a continuous beam and whether numerous vaccines can be given together in one dose. We also find out how higher heels make for a better runner and reveal the world's fastest camera. Plus, we find out why we get a better signal when holding an aerial and show you how to make a helicopter using card and pencils! Like this podcast? Please help us by supporting the Naked Scientists
