Hello and welcome to another episode of No Such Thing as a Fish coming to you from the

QI offices in Covent Garden. My name is Anna Koshinsky and I'm sitting here with Anne

Miller, James Harkin and Alex Bell and once again we have gathered around the microphones with

our four favourite facts in the last seven days and in no particular order here we go starting with

Anne's facts. My fact is that Ruby, a sheep who had been genetically engineered to glow in the dark,

was accidentally sold to an abattoir. So you would have thought if you genetically engineered a sheep,

you're keeping pretty close tabs on it. Apparently not. How did that happen? Well actually it may

have been an insider job. Maybe someone would have grudged against the company. What one

is the other sheep? Yeah. It's very cloak and dagger stuff. So this is the National Institute

for Agricultural Research in Paris and actually it was Ruby's mother, Emerald, was given this jellyfish

gene which makes her glow in the dark and then Emerald had a lamb Ruby who had the same gene but

I'm not sure if it was active as she actually was glowing but it was revealed this year that last year

yeah made it into the food chain and they've been very sincere to people and they won't

arrest you. You ate Ruby, you're all right but somebody did buy her, someone did eat her.

We are constantly making animals glow in the dark these days and it's always for apparently

scientific purposes. I'm so suspicious and also it's always bloody jellyfish isn't it? I think

sometimes in enemies but usually we just see the jellyfish from the sea take its genes out and

inject them into something. They must be so fed up with it. It's because jellyfish have this particular

protein called GFP which stands for? Green fluorescent protein. Yep and they this particular protein

when you put it into other animals it doesn't really have any other effects on the animal or

hardly anything anyway and so it's quite safe. There are other animals which have these kind of

proteins but they're not quite as useful really. We never use it as a marker so they can see
