Hi everyone! What an exciting week we have had; hundreds of live chats and questions flying in from every direction!

We have been super-busy reading and replying to all of your questions, remember that you can comment on them too. Just go to the zone that you asked your question in and comment on the scientists answers as much as you like! You can also post questions for the scientists there as well.

We hope that you have enjoyed the first week as much as we have and are looking forward to Monday; remember though if you want your favourite scientist to stand a chance of winning you need to VOTE by Tuesday!

Who will win? Only YOU decide!
