promoted Burnley FC special. Good morning, Newsrounders, and

welcome to all of Friday's best stories with me, Ayshah. Coming up:

Why this house in China has been turning upside down. Amla: Icon Tim

Peake and I am an astronaut. What do you think I should be eating in

space? First, to a row over one of the

world's biggest natural wonders. Scientists are unhappy with a

decision to dump waste material into the Great Barrier Reef, off the cost

of Australia. The Government there has decided to allow the dumping of

millions of tonnes of sludge from the sea bed in order to make room to

expand a major coal port on the coast. But scientists from UNESCO, a

world science group, say it's so bad for the marine life on the reef that

it's putting the site in danger. At the end of the day, what determines

the health of the reef? It is water quality. There is a recognition of

water improvement. There is recognition of a deep, clear,

long-term plan on water quality. To the latest on Ukraine next, where

there's reports that the country's army have launched an attack aimed

at taking back control of the City of Sloviansk. It's currently

controlled by groups that want Russia to have more influence in the

country as part of forced takeovers of several towns and cities across

the east of Ukraine. Ukraine's government is trying to drive them

out, with reports of gunfire and military helicopters flying over the

outskirts of the City this morning. And you can find out more about the

history of what is happening in Ukraine on the newsround website.

What does an astronaut eat in space? Well, today, the UK Space Agency is

giving you the chance to decide. Children aged eight to 14 are being

asked to design a meal for British astronaut Tim Peake to eat when he

heads into space. But the food he'll eat needs to last a long time, be

healthy and be suitable for the conditions in space. Newsround

chatted to Tim at his training in Houston, Texas, to give you some

tips. The competition is for young students to design a meal for me to

eat in space. The winning teams will get to actually prepare this meal

with celebrity chef Heston Blumenthal. The ideal meal is

something which obviously tastes really nice, something which

triggers memories - whether that's friends or families or the outdoors.

You don't want to just open up a packet of warm mush that doesn't

taste very good - it gives you the right nutrition, but it doesn't

taste very good. You want it to be something exciting. It's got to last

a long time. Two years' shelf life is a minimum. Then it has to be able

to travel up to space, so it needs to be in a sealed packet. That might

be in a can, it might be in a foil pouch, for example, or a a plastic

pouch. And also, you don't want too many crumbs from something like

bread or biscuits, because crumbs also are going to get all over the

place, and they're going to get into the air ventilation system and

you're going to end up having to clean out all of your filters at the

end of the week. We only have a hot water dispenser on board the Space

Station or a can heater, so those are the two ways we can get heat

into our food. On the whole, the space food is not bad, but I think

there's room for improvement. More on that in half an hour.

And sticking with out-of-this world news, NASA's been showing off what

they hope will be news, NASA's been showing off what

worn by the first astronauts to fly to Mars The American space agency

have revealed these pictures of the Z-2 spacesuit.

have revealed these pictures of the light-emitting patches and other

technology to adapt to who's wearing it. It's only a prototype at the

moment and beat off two other designs that the public voted for.

Imagine never meeting your brother or sister for 80 years Well, that's

exactly what happened with Elizabeth Hamel and Ann Hunt. That is exactly

what happened to these two twins, who were separated at birth. How

lovely to see you in the flesh! This is the moment sisters Elizabeth and

Anne-Marie United. One was adopted as a baby and one moved to America.

They were brought back together as part of a special project. Before

that, Anne-Marie didn't even know she had a sister. I wanted to pinch

myself. Am I dreaming? I've got someone... You know, as well as me.

Part of me, you know? A twin. Over in China, this very

strange-looking house is proving very popular with people. No, you're

not looking at it the wrong way round. The house has been made that

way on purpose. And when you head inside, everything is stuck on the

ceiling, including the bed, sofas, chairs and tables and even the

toilet. Might give that one mess.
