Hello there, Ricky here live in the Newsround studio

We bring you the birds that could teach drones to fly.

And can your dog really understand what you're saying?

But first, have you ever wondered how birds manage to fly,

Well a team of scientists in the US created a special

BBC Science reporter Victoria Gill went to see it.

Scientists have a lot to learn from this little lovebird.

How such tiny birds fly smoothly through gusty air

So scientists at Stanford University have built this.

We worked for four years to design this and build this.

It was put together specifically to study how birds fly.

We can use the best possible techniques.

Those techniques include cameras that film in extreme slow motion,

capturing tiny wing adjustments that keep the birds steady in the wind.

It is the latest ambitious experiment in a lab here

in California that is dedicated to unravelling the secrets of flight.

Diana works with these birds every day.

She uses clicker training and food rewards so they will fly to wherever

The ultimate aim is the design of tiny flying robots like these.

By copying what birds do, engineers can build much smaller,

steadier robots that they could then send out after a disaster to search

So these scientists will aim to create robotic copies

of what nature has perfected over millions of years.

Next, air pollution in cities hasn't improved enough

A new report by the Royal Geographical society says

pollution caused by cars, buses and lorries makes the air

in some cities bad enough it could make some people ill.

The government says its trying to reduce air pollution,

but experts say more needs to be done to encourage people

Now, to the farm in Cornwall that's selling some of their animals.

Only the farmer isn't selling sheep or cows,

More than 10 years ago these camels were brought

Since then the heard has got bigger and bigger now farmer Christopher

needs to find some of them a new home.

They love people. It's always a pleasure to be with the camels

because they are very social animals.

They're pulling in the crowds at this farm, but I don't think any

of their parents are ready to give them a home just yet.

I'm living in a flat in Bournemouth, they are a bit too big for the

balcony. No, they are too smelly. As lovely as they are, no.

So if you're seriously thinking about getting a camel well here's

They're desert animals, so they need somewhere dry

They like company, so you might need to get more than one!

Make sure you've got good fencing, because they can eat their way

And don't forget a camel isn't just for Christmas,

you need to be committed as these animals can live for up to 40 years.

So if you've got between ?3,000 and ?8,000 in the bank - then

Now the next time you dig out your pencil case,

you might think a bit differently about one of these.

This man in Taiwan in east Asia can create tiny

It takes him hours to carves these intricate designs.

Here's one he made of the Eiffel Tower.

Lee Chien-Chu has to use a magnifying glass so he can

Ever wondered if your dog can really understand what you're saying?

Researchers from Eotvos Lorand University in Hungary have

Using a machine which measures brain waves and doesn't hurt the dogs,

called an MRI scanner, they found canines can recognise

certain words and even tell the difference between how the words

A restaurant in Sydney, Australia cooked up the creations.

There's also veggie options and it got lots of fans excited,

That's all from me, Newsround's back right here tomorrow with Leah.
