The Hello, welcome to the naked scientist. I'm Chris Smith and for the first part of

the program I'm joined by Kat Arnie to take a look at what's been making science headlines.

Oopi-2 I want to be like you

whoa I want to walk like you talk like you too we'll be monking around with chimpanzees.

From under the sea fish send us a status update on their calm dioxide levels.

We hear about a genetic breakthrough that could lead to a treatment for diabetes. We find out why Tibetans find out why Tibetans find it easy to live at

altitude and as the tour of France starts in Yorkshire we take a look at the

history and science of the bicycle.

First, have you ever wondered where our tendency to use gestures to signal our intentions to others comes from?

Well, surprisingly, humans aren't the only animals to do this.

Our close relatives, the chimpanzees' gesture to each other too.

And now two scientists from St Andrews have worked out what chimps are saying,

as science reporter Victoria Gill explains. This is about chimps are saying. A science reporter, Victoria Gill, explains.

This is about chimpanzee communication and it's not about vocalizations, it's about the

gesturing that they do. So this is a team from St Andrews University up in Scotland, but they are spending time in Uganda at their field site at this national pedongo National Park following two habituated groups of chimps.

So habituated just meaning they are wild but they're used to

having human observers around and they've just followed them tirelessly for hours and

hours on months long field trips watching their interactions and what they're saying is that they've got a

distinct number of different gestures that they use to communicate so things they do with their

bodies and their faces holding their feet up stomping their feet moving their hands in
