adenovirus (c) National Cancer Institute

Has all the air in the world been breathed before?  Are any viruses beneficial to health?  Can naked farts transmit diseases?  You set the agenda in this Naked Scientists Question and Answer show in which we also discover how Inuit cope without fruit and veg, whether muscles can become cancerous and how long before we can teleport to work.

  • 12:56 - Would filtering farts prevent hospital acquired infections?

    Chris, Excellent interview on farts. If all the assholes in a hospital had effective fart-gas filters (that is ALL the patients and all the staff - I know, good luck on the staff side,) what would the reduction in Hospital Acquired Infections be? I understand all the air...

  • 44:24 - Why can't I get a car window to fog up twice?

    This question is for my 7 year old son Colin. When I breathe hot breath on a cold car window it steams up. When I draw on the window in the foggy part or I wipe off the fog I can't breathe on it again to make it foggy. When I take a hot shower the mirror gets foggy. When I wi...

  • 54:58 - Would turning off standby devices increase my heating bills?

    Hi, I've been pondering about the following; We are often told that we can gain large energy savings by shutting off all those transformers and stand-by devices, such as televisions, computers, printers etc., in our homes that are using energy. Instead we should turn off the d...

  • Is there a limit to human performance?

    Hello there, Naked Scientists! I am aware of Moore's law, and hope technology can find a way around it when the time comes. What about physiology? I am not a big sports fan, but when I do get a chance to watch talented athletes, it is always so close! They train to beat their ...
