:00:25. > :00:27.But first, Sutton United are out of the FA Cup
:00:28. > :00:34.They were the lowest-ranked club left in the competition,
:00:35. > :00:38.but the Premier League giants were too strong in the end,
:00:39. > :00:41.winning 2-0 in the end with goals from Lucas Perez and Theo Walcott.
:00:42. > :00:43.Arsenal will now host another non-league side, Lincoln City,
:00:44. > :00:52.Despite the result, it was a proud day for Sutton fans.
:00:53. > :00:56.I thought that Sutton played really well today.
:00:57. > :01:04.I think Jamie Collins did really good defending.
:01:05. > :01:06.I think they did deserve to get a goal.
:01:07. > :01:08.Some players didn't have a good night.
:01:09. > :01:20.But I really think Sutton should have got one back.
:01:21. > :01:22.It was a good match, we can't help it, it was a
:01:23. > :01:28.It was a good match, guys, you did yourselves proud.
:01:29. > :01:31.Next up, do you think you could spot a fake news story?
:01:32. > :01:33.Well, thousands of them are being shared online,
:01:34. > :01:36.and sometimes it's tricky to know if the story is real or not.
:01:37. > :01:39.Well, Ricky's set one school a challenge to see if the kids
:01:40. > :01:49.Have you ever been sent a video by your mates and thought,
:01:50. > :01:54.Or you've read story online and thought, that is unreal?
:01:55. > :01:58.Well, did you know that it could be fake news?
:01:59. > :02:03.And today, we're going to find out how you can spot a fake story.
:02:04. > :02:08.We've given this classroom six articles to read.
:02:09. > :02:11.But what they don't know is that every story is fake news.
:02:12. > :02:27.I loved the UFO one, because you could see it really
:02:28. > :02:30.clearly, and most of the pictures of, like, UFOs and stuff like that,
:02:31. > :02:39.The one that I most enjoyed was the baby one.
:02:40. > :02:44.When I was a baby, I was quite heavy, so I think I believe this.
:02:45. > :02:52.It's just all the detail, because you don't really see a story
:02:53. > :03:00.I don't think they'd put it in if it wasn't real.
:03:01. > :03:06.They just sounded a little bit weird.
:03:07. > :03:09.What if I told you that every story here was fake?
:03:10. > :03:20.I'm telling you that all of these stories aren't true.
:03:21. > :03:32.They look like they were actually on the news.
:03:33. > :03:40.OK, so fake news is really hard to spot, right?
:03:41. > :03:42.If it's really surprising, so shocking you don't believe it,
:03:43. > :03:48.It's normally there's somewhere to find the information
:03:49. > :03:50.where it comes from, and that will help you decide
:03:51. > :03:55.Also, just because it's been shared on the Internet,
:03:56. > :04:00.on your social media, doesn't mean it's true.
:04:01. > :04:03.And if you're not sure, ask an expert.
:04:04. > :04:07.Ask your parents, ask a friend who knows more about it than you do,
:04:08. > :04:15.Now, scientists have unveiled an ambitious plan to sail a research
:04:16. > :04:18.ship to the Arctic so it can drift across the North Pole.
:04:19. > :04:25.This is the Polarstern, a German research ship.
:04:26. > :04:30.It's huge, at 120 metres long, and it's got a huge mission.
:04:31. > :04:33.The vessel's going on the biggest single Arctic research
:04:34. > :04:40.It's sailing to the sea ice at the North Pole,
:04:41. > :04:45.where it will be left to get stuck, so it can drift across
:04:46. > :04:50.Well, researchers hope to get valuable new information in a place
:04:51. > :04:53.where the Earth's climate is changing fast.
:04:54. > :04:56.The decline of the Arctic sea ice is much faster than the climate
:04:57. > :05:01.models can reproduce, and we need better climate
:05:02. > :05:03.models to make better predictions for the future.
:05:04. > :05:05.And there is a potential that in a few decades
:05:06. > :05:08.from now, the Arctic will be ice-free in summer.
:05:09. > :05:13.Scientists will have to deal with extremely cold temperatures,
:05:14. > :05:15.and will also have to keep their eyes peeled for
:05:16. > :05:22.The incredible 1550-mile trip will begin in 2019,
:05:23. > :05:30.and is likely to take a year to complete.
:05:31. > :05:34.Finally, we all know this feeling - when you're trying to get the last
:05:35. > :05:41.Well, scientists from the US have invented a coating
:05:42. > :05:44.for the inside of bottles that allows whatever is
