Summary

Where does the Earth's water come from? It's thought that it arrived from space, carried by comets. But recent research suggests otherwise. Professor Katrin Altwegg is principal investigator in charge of Rosina - the tool on the recent Rosetta mission that is charged with answering this mystery.

DNA can survive a trip into space, according to a recent experiment. Dr Lewis Dartnell, an astrobiologist from Leicester University, explains the implications.

What sounds do the oceans make? Anand Jagatia reports. Dr Julius Piercy from the University of Essex listens to coral reefs. And his recent work could help us harness sounds to help restore damaged and dying coral reefs.

This week, the new Nobel laureates head to Stockholm to pick up their medals. Among them is Norwegian neuroscientist Professor May-Britt Moser. The question on nobody's lips; what was she wearing? Which is a shame because she wore a Matthew Hubble dress featuring Grid Cells - our brain's positioning system. Discovering these grid cells won May Britt her Nobel prize. Polymer scientist Professor Tony Ryan from University of Sheffield talks fashion and science with Adam Rutherford.

Producer: Beth Eastwood.

0:00.0	Choosing what to watch night after night the flicking through the endless
0:06.8	searching is a nightmare we want to help you on our brand new podcast off the

0:37.6	More information and whatnot at BBC.co. UK slash Radio 4.
0:41.6	It's the unexplored frontiers we face on today's program, see, space and fashion.
0:47.0	In just a minute we'll be probing the very first results from Rosetta and our valiant efforts to prevent seeding life on other worlds.
0:55.4	We bathe in the noises of the oceans, the rich soundscape of coral reefs and how they change
1:00.4	when the reefs are dying.
1:02.3	And it's the Nobel Prize ceremony this week with the
1:04.8	grand Swedish shindig itself. All the chaps will be doled up in ill-fitting penguin suits,
1:09.5	but we celebrate the one dress that has science written all over it. But first, the Triumph of
1:15.9	the Rosetta Project powers on. Just a couple of weeks after bouncing its lander around on the
1:20.3	surface of Comet 67P, data is already getting published.
1:25.0	This week, in a remarkably speedy turnaround in the journal Science,
1:28.8	a team from Byrne in Switzerland has discovered a result that has, as Sciences want to do, upturned what we had previously thought.
