Summary

Can sea water keep roads frost-free? Why does the LHC need to be so cold? How does antifreeze work and what's the freezing point of beer? This week we run the risk of frostbite to tackle the coolest science questions as well as warming up in the hot tub to hear what household appliances devour the most power! We also find out how researchers are growing stem cells from umbilical cord blood, the scientific reason why a needle is so hard to find in a haystack, and how the smell of a fertile woman boosts a man's testosterone. Plus, do people really look like their pets? Like this podcast? Please help us by supporting the Naked Scientists

0:00.0	Boldly going where no science show has gone before.
0:05.0	The Naked Scientists
0:10.0	Oh, hello and welcome to this week's naked scientists. We've got Diana O' Carroll here.
0:17.0	Hi Diana. Hello. And also Dave Ansel, Dave.
0:20.0	Hi Chris. And I'm Chris Smith.
0:22.0	Now coming up this week how scientists have discovered a new way to make large numbers of
0:26.2	stem cells that can be used to treat leukemia and these are stem cells that have been taken
0:30.6	from the umbilical cords of newborn babies.
0:34.0	Also, the scientific reasoning behind the needle in a haystack phenomenon
0:38.0	why hunting for rare things actually makes them much harder to find,
0:41.0	and we'll find out what the relevance of that is to
0:43.3	security at Heathrow. Plus how women can affect men's testosterone levels.
0:48.4	Indeed it is official your partner's menstrual cycle is probably affecting your hormones and we'll find
0:54.4	out what the consequences might be in just a minute.
0:56.7	Dina.
0:57.7	Thanks Chris and also this week it's our science question and answer
1:01.4	extravaganza. We're attempting to solve all your scientific
1:04.8	problems including can tapping a tin of fizzy drink stop it from exploding all over you. Can we create
1:10.8	artificial nerve signals and were people less smelly in medieval times?
1:15.2	Thanks Diana and in this week's very seasonal kitchen science I'll be showing you the science behind putting
1:20.0	salt on the roads keeping frost free and why seawater might not be an ideal alternative.
1:24.0	If you want to have a go at this week's experiment, we need some ice, a bowl, some salt and a thermometer.
