:00:52. > :01:00.chatted to Tim at his training base in Houston, Texas, to give you some
:01:01. > :01:04.tips. We only have a hot water dispenser
:01:05. > :01:08.on board the space station or a can heater. So they are the two ways we
:01:09. > :01:15.get heat into our food. On the whole, space food is not bad. I
:01:16. > :01:18.think there is room for improvement. You are from the UK space agency.
:01:19. > :01:21.Can you tell You are from the UK space agency.
:01:22. > :01:28.Can us why you have decided to run this competition? The biggest
:01:29. > :01:35.difference is food in space will float because of the microgravity.
:01:36. > :01:43.You can't have fit with crumbs because it will float away. What is
:01:44. > :01:50.the best food for space? Something that is moist and you can easily eat
:01:51. > :01:57.from a packet. We saw astronauts having spinach. What are some of the
:01:58. > :02:08.other foods? Astronauts love tortillas. What are some other ideas
:02:09. > :02:15.you think British will come up with? I can't wait to see it. They
:02:16. > :02:20.need to be inspirational and fun and have a sense of Britishness. What
:02:21. > :02:29.are some top tip is for kids entering the competition? They
:02:30. > :02:40.should look at the UK speech at -- UK space agency's YouTube site. I
:02:41. > :02:54.know that he doesn't like coconut. So, no coconut smoothies.
:02:55. > :02:57.A row over one of the world's biggest natural wonders. Scientists
:02:58. > :03:00.are unhappy with a decision to dump waste material into the Great
:03:01. > :03:03.Barrier Reef, off the coast of Australia. The government there has
:03:04. > :03:07.decided to to allow the dumping of millions of tonnes of sludge from
:03:08. > :03:11.the sea bed in order to make room to expand a major coal port on the
:03:12. > :03:15.coast. But scientists from UNESCO - a world science group - say it's so
:03:16. > :03:17.bad for the marine life on the reef that it's putting the site in
:03:18. > :03:21.danger. At the end of the day, what
:03:22. > :03:23.determines the health of the reef is water quality. There is a
:03:24. > :03:27.recognition of water quality improvement and a recognition of a
:03:28. > :03:36.clear, deep, long term plan on water quality.
:03:37. > :03:46.Next, to 12 is our going on a trek across Greenland. One brother is
:03:47. > :03:55.wearing kit somewhere to what Sir Ernest Shackleton wore years ago. I
:03:56. > :04:00.have only got a thin jumper. I need to know how my kit performs in this
:04:01. > :04:15.environment. I need to make sure I don't get frostbite. Just a pair of
:04:16. > :04:19.trousers, gloves and a hat. Now not meeting your brother and
:04:20. > :04:22.sister for nearly 80 years is hard to imagine but that's exactly what
:04:23. > :04:25.happened for these two twins who were separated at birth. They were
:04:26. > :04:31.brought back together as part of a special project. Before that, Ann
:04:32. > :04:34.didn't even know she had a sister. And finally, over in China, this
:04:35. > :04:37.very strange-looking house is proving very popular with people.
:04:38. > :04:41.No, you're not looking at it the wrong way round - the house has been
:04:42. > :04:45.made that way on purpose. And when you head inside everything is stuck
:04:46. > :04:48.on the ceiling too, including the bed, sofas, chairs, tables, and even
:04:49. > :04:55.the toilet. I might give that one a miss.
:04:56. > :04:56.That's all from me, Newsround's back right here in about half an
