:00:16. > :00:18.First, the police officer who died in the Westminster attack last month
:00:19. > :00:22.is being remembered today at his funeral.
:00:23. > :00:25.PC Keith Palmer was among those killed by an attacker
:00:26. > :00:29.Today, thousands of police officers from across the country stood
:00:30. > :00:33.in silence as his coffin was driven through London to
:00:34. > :00:37.Southwark Cathedral, where the service took place.
:00:38. > :00:41.For more on what happened in the Westminster attack,
:00:42. > :00:44.go to Newsround online where you can also find advice on what to do

:00:50. > :00:51.Moving on, two-thirds of the Great Barrier Reef
:00:52. > :00:53.in Australia has now been devastated by severe coral bleaching,
:00:54. > :00:59.A new survey of the reef shows that the latest damage is mainly
:01:00. > :01:03.Last year, the northern parts were badly hit.
:01:04. > :01:18.Have you ever wondered how coral becomes bleached? Well, did you know
:01:19. > :01:23.that it is actually an animal, so it can't make its own food like plants
:01:24. > :01:28.do. Because of that, it has formed a special friendship with a tiny
:01:29. > :01:33.planned, which is a type of algae. They live on the coral and make
:01:34. > :01:36.around 90% of the food that it needs to live. As well as giving them
:01:37. > :01:43.their bright and jazzy colours. French of goals! However, if the sea
:01:44. > :01:46.temperature gets too high or low, or there is pollution, it can cause the
:01:47. > :01:52.algae to get stressed out and they leave. This turns it white or
:01:53. > :01:56.bleached, and leaves it pretty hungry and vulnerable to diseases.
:01:57. > :02:01.If the water temperature returns back to normal, the coral can
:02:02. > :02:05.recover. But this can take many years and, recently, bleaching has
:02:06. > :02:08.been happening more often, giving coral less time to recover.

:02:20. > :02:24.the Best Supporting Actress award for playing Hermoine.
:02:25. > :02:27.This is an extraordinary piece of theatre, but it's still small,
:02:28. > :02:34.I do feel from what people are saying, it's like, "Oh, gosh,
:02:35. > :02:36.I didn't know it was possible that theatre could do that."

:03:24. > :03:26.It's one of the nine countries in the European Union
:03:27. > :03:29.Better make sure you take some Polish zlotys with
:03:30. > :03:42.Quickly swing through Belarus to Russia.
:03:43. > :03:45.If temperatures dip and it snows, it might be wise to pick up a ushanka,
:03:46. > :03:47.a traditional Russian hat with earflaps to keep warm.
:03:48. > :03:50.Kazakhstan is made up of lots of flat deserts,
:03:51. > :03:54.It's where Major Tim Peake and his fellow crew launched to get
:03:55. > :03:57.to the ISS and where he landed safely back on Earth.
:03:58. > :04:01.It's famed for tea, the Great Wall and for making lots of things such
:04:02. > :04:07.The train bosses say the 7500 mile trip to the city of Yiwu via train
