Happy New Year! For our first show of 2009, we take on your science questions. We find out how earthworms can get airborne, why people get cramp and why Dr Chris' hypnic jerk frightens people on the bus. We also listen to the flirtatious duet between two mosquitoes, find out how rocks are arranged on Mars, and how stem cells bring sight back to blind mice. Plus, we find out how to make indoor snow and explain why all of these snowflakes are identical, and in kitchen science Dave explains the science of sneezing on your computer screen!
