This week we debate whether wounds should be left open or covered up, why toenails - but not thumbnails - ingrow, what is hydatid disease, whether we can tag people to track them for life, what causes ringworm, the difference between a TIA and a stroke and what happens to the solid fuel boosters jettisoned by the space shuttle during ascent. Plus, a look at jumping spiders' eyes! Join Dr Chris on Talk Radio 702 for all the answers... Like this podcast? Please help us by supporting the Naked Scientists
