Could a Siphon be used in orbit? Why do leaves change colour in Autumn? How is immunity passed from mother to baby through breastfeeding? Why do earthquakes happen away from plate boundaries? How do microwaves heat up food? We storm through your questions this week as well finding out how Twitter can be used to monitor moods around the world, how carbon dioxide can be converted back into a fuel, how biomarkers hidden inside ECG's can predict the risk of a repeat heart attack and how glowing bacteria can send secret messages! Plus, in Kitchen Science, we make flames without fire by making iron burn...

I'm in the process of buying from a company that produces three products for power saving - one is a geyser blanket, one is the geyser timer switch, and one is a thing they called a ‘power saver’ which is the kind of capacitor thing which I understand from my research on the net ...
I've got a space question for you – so as far as I know, our solar system has got a pretty big asteroid belt. Is it possible to bring some of those asteroids close together enough that their combined gravitational pull would start gathering stellar asteroids and eventually form ...
I was on a business trip recently and experienced the earthquake, the 5.8 in Washington DC. My question is why do quakes occur that are nowhere near a tectonic plate boundary?

Chris Hill and Martin Siegert tell Richard Holligham about the technology which will be used to drill through over 3km of ice and look for life in a hidden Antarctic lake in this week's Planet Earth podcast.
You don't really think of iron as being particularly flammable, but as this experiment shows, get it hot enough, and it will burn away.

Here in the states, we have a liquid product called Rain-X. When you spread it on your windshield, then raindrops beat up. Rain-X seems to add an invisible waxy surface to the windshield. If the only light source is directly in front of you as with normal rural night driving, ...
I know that during pregnancy a foetus gets oxygen from its mother via the umbilical cord. I was wondering what effect this has on the mother. Does she inhale more, or simply use oxygen more efficiently? What happens to her oxygen saturation level?
