First, we need to congratulate the winner of last week’s prize pack.

Congrats go out to Kieran who’ll receive his Brian Cox signed book pack next week. Last week we asked ‘can astronauts burp in space?’

Enjoy your pack Kieran!

Enjoy your pack Kieran!

The answer is they can’t… that is of course if we are talking about the traditional gas burp. As there is no gravity to separate the liquids and solids from the gas in their stomachs the valve (muscle that works with gravity) at the top of their stomach isn’t completely closed, which means when they burp it comes up as a bomit (the burp-vomit) or as Charles Bourland, a consult for the NASA Food Technology Commercial Space Centre put it ‘the wet burp’.

A nice mental image for you there.

Now, moving onto this week’s episode of Science Club, Dara O Briain and his crack team of experts take a weird and wonderful look at the brain. Dara traces the brain’s journey from a useless organ once ditched by Egyptian embalmers to the centre of everything that makes us human.

Check out this animated sneak peek.

Science journalist Alok Jha asks whether smart drugs really make you brainier, oceanographer Helen Czerski explores cutting edge therapies allowing the brain to control limbs remotely and materials scientist Mark Miodownik takes apart a smart phone and shows us what brains are really made of.

Tune in this Sunday at 8.40pm on BBC Knowledge, Channel 612 on Foxtel.
