Hi, I'm Martin live with Newsround. On the way today: The new bike

helmet that is made using paper. And why Christmas has finally

arrived for space station astronauts.

First, Manchester United fans will be waking up happy this morning

after the team won 2-0 against Swansea yesterday. After three

defeats in a row, things were looking a bit worrying but goals

from Antonio Valencia and Danny Welbeck sealed the Reds' first

victory of the New Year. Elsewhere, Chelsea travelled to Hull

and won 2-0 whilst Sam Allardyce's struggling West Ham got a

much-needed win over Cardiff to get them out of the bottom three.

There are two Premier League games this afternoon. Newcastle against

Manchester City and Liverpool versus Stoke City.

Around 300,000 people been affected and many schools and businesses

closed after a chemical leaked my daughter is 13 and says she was

taking a shower regardless. I told her not to do that because when we

turned on our water today it smelt like cough syrup. Now, Christmas

might be a distant memory for you guys but not for astronauts at the

International Space Station who are just getting their presents now.

Gifts for the six astronauts, as well as food and equipment, were

sent by NASA on Thursday on the spacecraft Cygnus and they have

finally arrived. Next to China, and the big problem

facing its major cities. It's smog. Lots of people in China regularly

wear facemasks as recent estimates suggest that half a million people

die early every year because of conditions related to air pollution.

The Chinese government plan to spend ?180 billion on a massive clean-up.

Jenny's been looking into it. Imagine having to wear a face mask,

like this, just to go to school? It's part of daily life for many

children in China, like these twin girls from Beijing. The masks

protect them from the air they breathe in. There are good days in

China but take a look at one of the many bad ones. A thick grey smog,

containing gasses and particles linked to asthma and heart trouble,

covers the streets. You can't actually see some of the most

damaging pollution. It's called PM 2.5 and involves

particles that are microscopically small. This matters because the

particles are small enough, not just to get into the lungs, but also into

the bloodstream. This kind of pollution is measured by the cubic

metre of air. The World Health Organisation sets a maximum limit of

25 of these particles in this space. It says we shouldn't breathe more of

them within 24 hours. But a level of 200 is routinely reached in many

Chinese cities. The Government is trying to tackle

the problem by closing coal-burning power stations which are the biggest

source of pollution. They're also trying to limit traffic and

officials say they're confident they can clean up. But in some cases smog

has forced entire cities to close down. The International School of

Beijing have taken matters into their own hands by sealing off their

playground inside this massive inflatable dome, where the children

play breathing filtered air. The Chinese government is banking on

green technology for the future but pollution will be a reality there

for years to come. All cyclists are advised to wear

helmets when they get on their bike. Yours might look a little bit like

this. But now a new helmet has been designed and the inside of it is

made out of paper. Inventor Anirudha Surabhi studied woodpeckers when he

was trying to come up with a new design as their heads take a lot of

impact when it pecks. He noticed woodpeckers have a soft structure

between their beak and skull and he decided to recreate this within a

helmet using paper. That is one layer of honeycomb cells

and that is the second layer. You end up with tiny airbags. When you

crash they pop and go all the way to the bottom without cracking.

The Australian Open gets underway very late tonight, UK time. British

number one Andy Murray is hoping he can go all the way in the Grand Slam

after making a return following back surgery. Murray will play Go Soeda,

who is ranked outside the top 100, in the first round on Tuesday, and

defending champion Novak Djokovic says Murray could still be a threat.

I'm sure he had a big problem with his back and had the surgery but we

practised and played a little bit and he is striking the ball really

well. It will take a little bit of time to get into matchplay mode but

I'm sure he will be just fine. All today you've been telling us

what you think about the new series of The Voice which started last

night. Thanks for those comments, guys.

That's all from me.
