Stripping down science, the naked scientists.

Hello, welcome to this week's edition of The Naked Scientists with Dave Ansel, hi Dave, with Helen Scales.

Hello.

And we meet Chris Smith.

Now coming up this week, biodegradable bin bag.

Scientists have discovered how to make a form of plastic that breaks down in just a couple of months when you bury it.

Also scientists have spotted a flying saucer orbiting around Saturn, but it's not what it appears to be.

Plus, how penguins could hold the key to surviving asphyxia because they can tolerate

incredibly low oxygen levels that's all on the way Helen.

Thanks Chris this week it's also our science phone in show so we're looking at all

your science questions including solving how glue sticks things together and why is

it that the sea looks blue? Plus how would you like to how would you like your

reading matter served up to you in the future? Do you prefer a printed book or would you like

your format to be just downloadable so you can listen to it?
