Summary

With a new year comes a whole new stack of science questions to challenge Dr Chris, Dr Dave and Dr Kat. This week they explain where the sand in the Sahara comes from, whether mirrors can reflect x-rays, if it is dangerous to live near a phone mast, and whether splitting water could solve our energy problems. We are also joined by the editor of Chemistry World, Dr Mark Peplow, who talks about labs the size of a postage stamp, nanoparticles in exhaust fumes, and why putting milk in your tea might not be such a good idea, and sticking with chemistry, Dave Ansell discovers which household liquids...

0:00.0	Stripping down science, the naked scientists.
0:05.0	Hello, welcome to this week's edition of the naked scientist science phone in a whole
0:11.0	hour of your science questions and emails and that's with me Chris Smith with
0:14.7	cat Arnie and with Dave Ansel.
0:17.0	Hi there.
0:19.1	On the way this week, scientists have discovered the cosmic equivalent of a vacuum cleaner.
0:23.2	It's a massive black hole at the center of our galaxy and it recently swallowed up something
0:27.3	about the size of a planet.
0:29.1	Also, there's very bad news for storing radioactive waste, why there are some major holes in the plans that
0:35.1	nuclear sizes are put together.
0:36.1	We'll be finding out about those.
0:37.1	And also a step forward in our understanding of why some people develop dementia as they
0:41.8	age. More on that shortly, Kat.
0:43.4	And we'll be finding out why teams that play in the red
0:46.2	are more likely to win.
0:47.6	Is it a psychological advantage?
0:49.4	Or do they just do less washing?
0:51.0	And we're finding about the chemistry of a cup of tea with our
0:53.8	special guest Mark Peplow who will be joining us later. And in this week's
0:57.6	kitchen science I'll be doing some exciting chemistry on copper coins. The
1:01.0	ingredients you'll need are some dirty old chains, some
1:03.0	vinegar, some fruit juice, maybe some water. So if you want to win a prize
