:01:00. > :01:02.sports big as competition, the America's Cup. But it was during
:01:02. > :01:06.training for the event yesterday that his vessel flipped over in San
:01:06. > :01:13.Francisco Bay, trapping him underneath. He was brought to shore,
:01:13. > :01:17.but doctors couldn't save him. had a tragic day to day on the Bay.
:01:17. > :01:21.Our thoughts and prayers are with Andrew Simpson's family, his wife
:01:21. > :01:27.and kids. Since the news of Andrew Simpson's death was announced,
:01:27. > :01:37.tributes have been coming in from across the sporting world. Close
:01:37. > :01:42.
:01:42. > :01:50.friend Olympic champion Ben Ainslie was shocked. And Beth twiddle said
:01:50. > :01:54.she was sad to hear the news. We'll wait to hear how this shocking
:01:54. > :02:00.tragedy could have happened. Next, an amazing story of survival

:02:11. > :02:16.are now known to have died in the disaster when a clothing factory
:02:16. > :02:21.fell down. When your alarm went off this morning, how did you feel?
:02:21. > :02:31.Over the last 24 hours, we've been carrying out are in sleep experiment
:02:31. > :02:33.
:02:33. > :02:37.with a group of kids in Manchester. Loads of you have also been taking
:02:37. > :02:39.part in the Newsround website. Why are we doing this?
:02:39. > :02:44.Ricky has more. He's been up since 5am! Almost 1 million children from
:02:44. > :02:49.all over the world have taken part in a survey, which has uncovered
:02:49. > :02:53.some surprising stat. Research at Boston College in America asked kids
:02:53. > :02:57.in 50 countries about their sleep patterns. On average, almost half of
:02:57. > :03:03.primary school kids didn't get enough sleep, they found. America
:03:03. > :03:08.has the biggest problem, with almost three quarters of nine and
:03:08. > :03:15.ten-year-olds who took part in tests toughing from a lack of sleep. The
:03:15. > :03:22.UK was not -- England was not far behind. Experts are saying that this
:03:22. > :03:26.lot's gadgets are to blame. Gadgets have fast moving screens, which is
:03:27. > :03:31.quite engaging and complex. That can stimulate the brain and make it
:03:31. > :03:34.difficult to switch off. Yesterday I was here at this school in
:03:34. > :03:43.Manchester armed with Newsround 's special questionnaire. Today, I'm
:03:43. > :03:48.back. How did we get on? I had eight or nine hours, but I was a bit OP
:03:48. > :03:55.this morning. Last night, I had way too long on my tablet and I didn't
:03:55. > :03:59.get enough sleep. There are one or two who are not with it, and they
:03:59. > :04:04.find it difficult to learn. It's difficult for me as a teacher.
:04:04. > :04:08.results are in. Thank you very much. We are going to head back to the
:04:08. > :04:14.office now to take a look at these and find out if these guys are
:04:14. > :04:19.getting enough sleep. What did you learn? We spoke to 27 kids at school
:04:19. > :04:23.in Manchester aged between nine or ten years old, so this is just a
:04:23. > :04:32.snapshot. The most surprising thing was that three quarters of them take
:04:32. > :04:34.their gadgets to bed with them, and hide them under their beds, and the
:04:34. > :04:37.TV and those in smartphone devices and tablets are the worst offenders.
:04:37. > :04:44.We found out that a quarter of them say they could do with more sleep,
:04:44. > :04:49.which I thought was a surprising. Most go to bed at 9pm. Some of them
