:00:00. > 3:59:59At the top because all about those three teams, Liverpool, Manchester
:00:00. > :00:00.City and Chelsea, but Chelsea could go top if they win and Liverpool
:00:00. > :00:14.lose. It's Friday the 18th April. I'm
:00:15. > :00:19.Ayshah kicking off your weekend with some of this on the way.
:00:20. > :00:21.We investigate the rise of super-sized rodents in some of our
:00:22. > :00:27.towns and cities. Plus...
:00:28. > :00:30.But first, a new planet has been discovered that scientists say it's
:00:31. > :00:37.the most Earth-like one ever found. It's Called Kepler 186 F and was
:00:38. > :00:40.discovered by US space agency NASA. They're excited because it's only
:00:41. > :00:44.just bigger than Earth and has the potential to hold water, meaning
:00:45. > :00:47.there is an area on the surface where scientists say life could
:00:48. > :00:51.survive. This planet Kepler 186 F orbits a
:00:52. > :00:58.star which is cooler and dimmer than the sun. So while we may have found
:00:59. > :01:00.a planet that is the same size as Earth and receives a similar amount
:01:01. > :01:03.of energy to what earth receives it orbits a very different star, so
:01:04. > :01:12.perhaps instead of an earth twin we have discovered an earth cousin.
:01:13. > :01:15.Super-size rats have been munching on takeaways and our rubbish and now
:01:16. > :01:18.there are reports the oversized rodents are being seen more often in
:01:19. > :01:22.our towns and cities. It's thought that wet weather has forced the
:01:23. > :01:25.furry creatures into urban areas where they've been feasting on all
:01:26. > :01:29.our scraps, and according to recent reports from one Southampton rat
:01:30. > :01:32.catcher, how we get rid of our waste is allowing rats to get even bigger.
:01:33. > :01:34.Nel's on the case. Rummaging in bins and eating fast
:01:35. > :01:41.food. There are reports these scavengers are on the increase in
:01:42. > :01:47.number and in size. There are an estimated 10.5 million rats in the
:01:48. > :01:54.UK and it is the job of pest controllers like Sean, to catch
:01:55. > :01:58.them. The last few months, they are getting better -- bigger. Where we
:01:59. > :02:05.are going now is a private duty spot where there is a growing problem of
:02:06. > :02:10.rats. Why are they getting bigger? It could be more people living in
:02:11. > :02:17.our cities, the way we manage our waste and the wet winter and floods.
:02:18. > :02:24.How have they affected it? The storm drains filled with water so the rats
:02:25. > :02:26.have to get out of there and go somewhere else. We have not had
:02:27. > :02:29.floods for a while but they have moved into this city is a bit
:02:30. > :02:33.further, they will not go back if they have loads of food. Are the
:02:34. > :02:39.rats getting bigger? Will they continue to grow? What makes an
:02:40. > :02:46.animal change shape depends on what is around it. If there is a lot of
:02:47. > :02:51.food to eat, there can be rats that can grow to be much bigger than they
:02:52. > :02:54.are now, perhaps the size of a sheep or a cow. They have not evolved to
:02:55. > :03:01.become bigger, they have not changed from rats a few hundred years ago or
:03:02. > :03:06.even thousands of years ago. There have not been enough time for that,
:03:07. > :03:11.they are simply well fed rats. Rat catchers are calling on the
:03:12. > :03:14.government to allow the use of stronger poisons, but until then it
:03:15. > :03:20.looks like they are in for a busy summer.
:03:21. > :03:23.In other news, American President, Barack Obama, says he hopes a new
:03:24. > :03:27.deal to try and calm the tensions in Ukraine will be put into action -
:03:28. > :03:31.but he's not convinced. It follows a big meeting between key figures from
:03:32. > :03:34.the US, the EU, Russia and Ukraine yesterday. They agreed that armed
:03:35. > :03:36.groups supporting more Russian control should put down their
:03:37. > :03:39.weapons and stop taking over buildings in the east of the
:03:40. > :03:42.country. It follows days of clashes between those groups and the
:03:43. > :03:46.Ukrainian army but Obama says it's up to Russia to stop interfering. So
:03:47. > :03:53.how are things on the streets this morning?
:03:54. > :03:54.Eastern Ukraine World up this morning wondering what this
:03:55. > :04:02.agreement will mean underground. We have spent some time with protesters
:04:03. > :04:08.yesterday and they feel very determined to carry on. So many
:04:09. > :04:14.people were telling us they want this part of Ukraine to follow in
:04:15. > :04:18.Crimea's footsteps. And you can find out what happened in Crimea and the
:04:19. > :04:22.rest of what's been going on in Ukraine by checking out our special
:04:23. > :04:25.guide on the Newsround website. And William and Kate have been
:04:26. > :04:28.getting into the Easter spirit down under as they visited the Sydney
:04:29. > :04:32.Royal Easter Show. The Royal couple were greeted by huge crowds and
:04:33. > :04:36.admired the local fruit and veg before and watching a farmer sheer a
:04:37. > :04:45.sheep in remarkable speed. Not something I'd be able to do.
