look at the video that kick-started YouTube. Calvin Harris makes pop

history. First, scientists say we need to

clean up space because there is too much junk up there. A new study says

the number of abandoned satellites above the Earth will lead to

catastrophic collisions. This could damage vital missions. Martin has

been to meet Tim O'Brien, who explained how we could get rid of

some of it. Send up a robotic spacecraft. It fires this harpoon

out which buries itself in the spacecraft and then they drag it

into a position where they can direct it back into teRt's

atmosphere. Next, Ben Wright is on the street where it happened and

sent Newsround this report. It is more than a week since two

bombs went off in the American city of Boston during the marathon

killing three people and injuring many more. Life is beginning to

return to normal. The road where the bombs went off is still closed to

everybody because police are still searching for evidence as they make

a case against the people they think were responsible for this. They

believe that there were two brothers who planted the bombs. One of them

died on Friday after a gun fight with police. The second is very

injured but he is in hospital and yesterday, the 19-year-old, Dzokhar

Tsarnaev, was charged with using a weapons of mass destruction against

the American people. It is a very serious crime. He might face the

death penalty. He is alert. He understands the charges against him.

Now the police and the city want a trial to happen so they can bring

him to justice. Next, it has been called one of the

biggest doping scandals in British horse racing industry. 11 horses

were found to have steroids in their bodies when they were tested. The

drugs are not allowed because they give animals an unfair advantage in

races. Mahmood Al Zarooni has admitted making a catastrophic

error. He will now face a disciplinary hearing.

These kids on a building project are among millions of children who have

to work to survive instead of getting an education. Many children

in Bangladesh work to make pots. One of the main goals for the United

Nations is primary education for every child by 2015. There are still

61 million primary aged kids out of school.

Pakistan has the second-highest number of out of schoolchildren in

the world. Many children don't go to school because they have to work to

provide for their families. TRANSLATION: If you work in shops

during the day, raise your hand. TRANSLATION: My uncle works in the

market selling flowers. I help him. The head teacher has been the

principle running the school for disadvantaged children.

TRANSLATION: These kids are poor and their parents must make them work.

It is my job to make sure these kids study. The classroom is the

playground of the local park. They are taught all the usual subjects

like English, maths and science, as well as Islamic studies.

TRANSLATION: If we have education, we will never be poor. We can

provide better lives for our families. Education is going to be

the only way some of these kids get out of poverty. It is hoped as the

principle includes more kids into his unusual classroom, that many

more can be helped. Now, it looks like we may have a new

King of Pop. Calvin Harris has become the first act ever to have

eight top ten singles from one albums. Calvin's beaten the previous

record of seven held by Michael Jackson. It is after his Ellie

Goulding collaboration on I Need Your Love.

Last up, are you older than YouTube? It is eight years old today and this

was the first-ever video to be up loaded. Here we are...Pretty
