Hello there. Ore and Sonali with you tonight, with all the very

latest news from across the world. Here are a couple of things we've

got lined up for you... Leah photocopies her own head... And

find out why these large creatures are facing big problems. All that

to come, but first we're heading to Libya, in North Africa. After

months of fighting it looks like the country's leader, Colonel

Gaddafi, is about to be overthrown. He's been in power there for more

than 40 years, but lots of Libyans want him out. Overnight, rebels who

don't want Gaddafi ruling the country stormed the capital city,

Tripoli. These have been the scenes there today. Celebrations on the

streets, but the fighting is still For these Libyans, the last six

months of fighting have been building up to this - their chance

to take control of the capital city and topple their leader, Colonel

Gaddafi. The fighting began in February. Libya's neighbouring

countries Tunisia and Egypt also had unpopular leaders, but the

people there rose up, rallied together and forced them out. Many

Libyans saw what had happened and wanted to do the same to Colonel

Gaddafi. During his years in power, Gaddafi has put people who disagree

with his views in prison and sometimes had them killed. Gaddafi

refused to go and tried to stop people protesting against him. In

March, several countries including Britain and America sent planes

into Libya to bomb government tanks and planes to try to stop Gaddafi

attacking his own people. The fighting continued throughout the

summer, and then this weekend, it became even more intense as the

rebels advanced towards the capital. It's really dangerous. This BBC

reporter came under fire from Gaddafi supporters as he travelled

with rebel fighters. The British Prime Minister, David Cameron,

returned from holiday early because of what's happening and says it was

right for Britain to get involved in the fighting.

It was necessary because Gaddafi was going to slaughter his own

people. That massacre of innocent people was prevented. Although

there are Libyans who say they're ready to form a new government, no-

one is really sure what's going to happen next. But for the time being,

these people are just glad that it looks like change is happening. Two

of Colonel Gaddafi's sons have now been captured by the rebels but

Gaddafi himself has gone into hiding. Fighting is still going on.

Head to our website for all the Next to a big problem facing rhinos

in Africa. More and more of them are being hunted and killed for

their horns. Just listen to these numbers - four years ago in South

Africa, 13 were killed by poachers. That number rose to 300 last year.

Poaching rhinos is illegal. The UK is now heading up a campaign to get

other countries to help stop it. There are five species of rhino in

There are five species of rhino in the world. Four of them are

officially under threat of extinction. That's because more and

more rhinos are being killed for their horns every year. So far this

year more than 200 rhinos have been poached in South Africa. It's all

because of a myth that has spread through Asian countries that says

rhino horns can be used as medicine to cure cancer. It's not true, and

scientists all agree that rhino horns can't help humans. But the

belief that they're a cure for cancer has made people want to buy

them. They're in such huge demand that they're now worth �50,000 a

kilogram - that's more than diamonds and gold. Getting so much

money for selling the horns means poachers don't want to stop hunting

the animals. Even in the UK, burglars have stolen rhino horns

from museums to make cash. So now the British Government is asking

China, Vietnam and other Asian countries to tell their citizens

that rhino horn isn't a medicine. Rhino horns are made of something

called keratin, which is the same stuff that's in our hair and our

fingernails. The UK Wildlife Minister is hoping if this is

explained to people in Asia, they won't buy rhino horn illegally, and

that will help stop the poaching that could very soon wipe out these

Next we're talking technology in a new dimension. We've had 3D movies,

we've had 3D TV. But now, make way for... 3D printers! It's what we've

all been waiting for! Well, Leah has been anyway! Printers are not

usually very exciting. But that's all changing. At this design

college, they're using 3D technology to print drawings as

real-life objects. First of all, we come along with this model, which

we draw up in the commuter, -- computer, and then withdraw it up

in the machine. It works layer by layer. The platform burns down and

builds up another layer. Eventually we have the whole thing.

printing can be used to make anything from midi models for

architects to medical supplies. The idea is that one day you will be

able to print off toys, jewellery and even mobile phone accessories.

Time to see it in action. This camera takes loads of pictures of

my head. They're then fed into a computer to build up a 3D image

which can be printed out. It is as easy as that. Hundreds of layers of

fine powder are built up to make the finished model. But printing a

3D image of yourself takes quite a lot of time. You can buy personal

3D printers. They're very expensive, but the technology is changing

quickly, so they could be more widely available in the next few

years. And here it is full stop I would say that's weird. And why

didn't they make her have a happier face? That's a lot to get your head

around. If you thought Blue Peter's Helen Skelton was a daredevil, you

ain't seen nothing yet! A Swiss man has broken the world record for the

longest and highest ever tightrope walk without a balancing pole. With

no security harnesses at all, Freddy Nock walked almost a

kilometre up this 2" cable car rope in Germany. And we can't go without

gloating in the glory of England totally thrashing India in the

cricket. The number one Test team in the world - feels good to say

that - are celebrating a series whitewash over India after winning

the final Test by an innings this afternoon. India did show some
