and this is what we've got coming up on Newsround. Every morning when I

come to school I'm tired. We get the results of our sleep

experiment... And the woman found alive after

being trapped under a collapsed First we begin with some sad news -

the death of the British Olympic sailor, Andrew Simpson, in a

training accident in America. Tributes have been paid from across

the sporting world to a man who won two Olympic medals for Great

Britain. Nel has this report. A gold medal in Beijing, a silver at

London 2012. Andrew Simpson was a top-class sailor, preparing for the

sports big as competition, the America's Cup. But it was during

training for the event yesterday that his vessel flipped over in San

Francisco Bay, trapping him underneath. He was brought to shore,

but doctors couldn't save him. had a tragic day to day on the Bay.

Our thoughts and prayers are with Andrew Simpson's family, his wife

and kids. Since the news of Andrew Simpson's death was announced,

tributes have been coming in from across the sporting world. Close

friend Olympic champion Ben Ainslie was shocked. And Beth twiddle said

she was sad to hear the news. We'll wait to hear how this shocking

tragedy could have happened. Next, an amazing story of survival

in Bangladesh where woman has been pulled from the rubble of a

collapsed building 17 days after it collapsed. She is thought to have

stayed alive by drinking from a water pipe. More than 1000 people

are now known to have died in the disaster when a clothing factory

fell down. When your alarm went off this morning, how did you feel?

Over the last 24 hours, we've been carrying out are in sleep experiment

with a group of kids in Manchester. Loads of you have also been taking

part in the Newsround website. Why are we doing this?

Ricky has more. He's been up since 5am! Almost 1 million children from

all over the world have taken part in a survey, which has uncovered

some surprising stat. Research at Boston College in America asked kids

in 50 countries about their sleep patterns. On average, almost half of

primary school kids didn't get enough sleep, they found. America

has the biggest problem, with almost three quarters of nine and

ten-year-olds who took part in tests toughing from a lack of sleep. The

UK was not -- England was not far behind. Experts are saying that this

lot's gadgets are to blame. Gadgets have fast moving screens, which is

quite engaging and complex. That can stimulate the brain and make it

difficult to switch off. Yesterday I was here at this school in

Manchester armed with Newsround 's special questionnaire. Today, I'm

back. How did we get on? I had eight or nine hours, but I was a bit OP

this morning. Last night, I had way too long on my tablet and I didn't

get enough sleep. There are one or two who are not with it, and they

find it difficult to learn. It's difficult for me as a teacher.

results are in. Thank you very much. We are going to head back to the

office now to take a look at these and find out if these guys are

getting enough sleep. What did you learn? We spoke to 27 kids at school

in Manchester aged between nine or ten years old, so this is just a

snapshot. The most surprising thing was that three quarters of them take

their gadgets to bed with them, and hide them under their beds, and the

TV and those in smartphone devices and tablets are the worst offenders.

We found out that a quarter of them say they could do with more sleep,

which I thought was a surprising. Most go to bed at 9pm. Some of them
