:00:20. > :00:24.Good morning, it's Tuesday, I'm Jenny and this is Newsround.
:00:25. > :00:27.First up, some space news and a new camera satellite has been
:00:28. > :00:28.launched by the European Space Agency.
:00:29. > :00:32.Satellite Sentinel 2B will join another satellite already in space
:00:33. > :00:35.to take pictures of the Earth's surface every five days and send
:00:36. > :00:38.back information about pollution levels in lakes and coastal waters,
:00:39. > :00:44.as well as monitor forests all over the world.
:00:45. > :00:46.Also helping to measure pollution are some unexpected
:00:47. > :00:53.Yes, pigeons are being used in an experiment to learn
:00:54. > :00:58.Martin has been 'coo-vering' over the story.
:00:59. > :01:04.I see them all the time in the city, trying to find bits of food
:01:05. > :01:08.But how are they linked to pollution
:01:09. > :01:13.- apart from both starting with the letter P?
:01:14. > :01:15.Well, scientists are using pigeons to gather information by strapping
:01:16. > :01:24.It is known that pollution that comes of our cars with diesel
:01:25. > :01:27.engines rises to rooftop level, but what isn't known
:01:28. > :01:30.is what happens next to the pollution, where does it go?
:01:31. > :01:46.I thought, well, birds, they fly everywhere. If they can carry the
:01:47. > :01:48.senses, and they are tiny enough, we can start to understand the
:01:49. > :01:50.dispersion of pollution around the city.
:01:51. > :01:55.Birmingham University are carrying out a test flight.
:01:56. > :01:59.I feel nervous. It is the first time we have done this.
:02:00. > :02:02.One of the pigeons is fitted with a small, lightweight sensor
:02:03. > :02:12.I am happy with that. I just hope they go home.
:02:13. > :02:15.Just six minutes later, the pigeons are back and the sensor
:02:16. > :02:24.The light is still flashing. That's a good sign!
:02:25. > :02:28.Rick and his team have been able to find out the route the pigeons
:02:29. > :02:32.The information will help them to figure out how pollution
:02:33. > :02:42.What is this pigeon called? I haven't got a name for him. I call
:02:43. > :02:45.him number 80. So thanks pigeon number 80,
:02:46. > :02:47.you've done everyone proud. OK, time for a quick look at the top
:02:48. > :02:50.sports stories today. Chelsea are now 10 points ahead at
:02:51. > :02:53.the top of the Premier League table. Last night they beat
:02:54. > :02:56.West Ham 2-1 thanks to goals Manuel Lanzini managed to get a goal
:02:57. > :03:02.for the home side in injury time. Arsenal manager, Arsene Wenger,
:03:03. > :03:06.says there was no training ground argument between Alexis Sanchez
:03:07. > :03:08.and his team-mates before Arsenal play Bayern Munich
:03:09. > :03:17.in the Champions League tonight, and have to come back from being 5-1
:03:18. > :03:20.down after the first leg. And Manchester United's Zlatan
:03:21. > :03:22.Ibrahimovic and Bournemouth's Tyrone Mings are in trouble
:03:23. > :03:26.with the football authorities. During their match
:03:27. > :03:28.on Saturday, Mings appeared forward before Zlatan seemed
:03:29. > :03:31.to elbow him in the Now time to tackle a real
:03:32. > :03:44.black and white issue. This has been bamboozling me for
:03:45. > :04:00.years. It is a bit of a grey area until
:04:01. > :04:04.now. One third is all one colour. Pandas have black and white patches.
:04:05. > :04:10.Scientists think they know why. Unlike some other types of bears,
:04:11. > :04:15.pandas are active all year round. If they go in search of bamboo to eat
:04:16. > :04:20.they move from warm rain forests to snowy mountains, so the two colours
:04:21. > :04:23.help them. The white helps them to blend into snow surroundings and the
:04:24. > :04:29.black helps them to hide in shady forests. The black ears might look
:04:30. > :04:35.cute but they are actually a warning to other predators. They are a sign
:04:36. > :04:40.of aggression. Number three, the famous panda eyes. These patches are
:04:41. > :04:45.unique. They vary in shape and size from pander to pander. It is thought
:04:46. > :04:50.they help them to recognise each other. Why are they black and white?
:04:51. > :04:51.It is all about blending in, scaring away predators and getting to know
:04:52. > :04:53.each other. That's all from me, Newsround's
:04:54. > :04:55.back right here at 8.15, where you can find out how
:04:56. > :04:58.this student is helping to tackle air pollution,
:04:59. > :05:04.with his backpack.
