:00:00. > :00:11.It is Friday afternoon and you are watching newsround. We have plenty
:00:12. > :00:15.to tell you about. I am finding out how to stay safe
:00:16. > :00:19.around dogs. And find out why scientists are
:00:20. > :00:22.giving praying Mantis is the glasses!
:00:23. > :00:24.But first, the RSPCA says it's concerned about the rising number of
:00:25. > :00:28.children in England being taken to hospital because of dog bites. The
:00:29. > :00:31.animal charity says more should be done to teach people, particularly
:00:32. > :00:39.young kids, how to behave around dogs. Leah has more.
:00:40. > :00:43.Dogs can be loads of fun. They can feel like our friends, be great to
:00:44. > :00:47.play with and can even become part of the family. But, sometimes if we
:00:48. > :00:52.don't know what we're doing around them - things can go wrong. Over the
:00:53. > :00:56.past five years in England, the number of people going into hospital
:00:57. > :00:59.for dog bites and injuries has gone up. Getting a serious bite from a
:01:00. > :01:10.dog is still really rare, but it's kids aged nine and under who are
:01:11. > :01:16.most at risk. I was walking with my friends and the dog ran after me.
:01:17. > :01:22.You should ask owners before you/ them. I was on my bacon and this dog
:01:23. > :01:27.chased me around the park. The order call it back but it scared me. If
:01:28. > :01:32.you/view. It may not be very friendly and it could make you. Many
:01:33. > :01:39.children don't know how to react around dogs, the cab pick-up at the
:01:40. > :01:44.dog is anxious. Think the dog is smiling when in fact it is a warning
:01:45. > :01:50.sign that the dog is getting into attack mode. What advice would you
:01:51. > :01:55.give to children? Do not panic. Don't make any big movements. Like
:01:56. > :02:01.running or approach the dog. Stay still. Do not look the dog in the
:02:02. > :02:04.eye and back off very slowly. With summer in the way more and more of
:02:05. > :02:07.us will be out and about so it is more important that we learn how to
:02:08. > :02:10.behave around our funny friends. Next, the UK is to get one of the
:02:11. > :02:13.biggest, most advanced polar research ships in the world, it's
:02:14. > :02:16.been announced today. Costing ?200 million, it'll be a major upgrade
:02:17. > :02:19.over Britain's two current icebreakers like this one. It'll
:02:20. > :02:23.have a helipad, onboard laboratories, and the ability to
:02:24. > :02:34.send out submarines. But why is this so important? Is a big investment
:02:35. > :02:38.but it is important because the polar regions are changing so fast
:02:39. > :02:43.at that matters to all of us goes this can affect the weather, the
:02:44. > :02:47.level of the sea, wildlife, it can create new shipping routes across
:02:48. > :02:50.the roof of the world. To understand that you can just use the
:02:51. > :02:52.satellite, any ships to get in there.
:02:53. > :02:55.Next, it's looking less and less likely that anyone will be able to
:02:56. > :02:58.climb the world's highest peak, Mount Everest, this year. An
:02:59. > :03:01.avalanche last week killed sixteen local guides, known as Sherpas and
:03:02. > :03:04.it's started big argument over safety on the mountain, and how much
:03:05. > :03:08.Sherpas are paid. Now teams are starting to come down from Base
:03:09. > :03:16.Camp, saying it's not safe to attempt to reach the summit. Having
:03:17. > :03:21.been there and seeing the conditions myself and seeing the repeated
:03:22. > :03:25.avalanches again and again, that is not snow but face, greasy and
:03:26. > :03:29.speaking of her coming down. I know for certain that those conditions
:03:30. > :03:32.are not safe. Club legend Ryan Giggs has given his
:03:33. > :03:36.first press conference as stand-in manager of Manchester United. Giggs
:03:37. > :03:39.is in temporary charge for the rest of the season, after David Moyes was
:03:40. > :03:43.sacked this week. He says taking charge of the club he's supported
:03:44. > :03:51.since he was a boy, was the "proudest moment" of his life.
:03:52. > :03:56.I would like to just say I am very proud to be managing for the
:03:57. > :04:03.remaining four games. The club that I supported all my life. I have been
:04:04. > :04:06.associated with it for 2526 years so it is a proud moment for me. One
:04:07. > :04:09.that I will enjoy. This right here is a praying mantis,
:04:10. > :04:12.with a difference. Because this little guy is wearing the world's
:04:13. > :04:15.smallest 3D glasses! They're the only invertebrates able to see in
:04:16. > :04:19.three dimensions - other insects only see in 2D. So scientists at
:04:20. > :04:23.Newcastle University are studying mantises to find out how other
:04:24. > :04:26.creatures developed 3D vision. They hope it'll help create new robotic
:04:27. > :04:40.technology in future. But just how do you get five millimetre glasses
:04:41. > :04:46.onto an insect? We fix them on to deeply in Mantis
:04:47. > :04:49.using beeswax so we melt the glasses on to the Mantis and after we are
:04:50. > :04:53.finished with the experiment we can melt the wax and remove the glasses.
:04:54. > :04:57.They are detachable. More on that story on the website, make sure you
:04:58. > :04:59.check it out. We are back tomorrow. Goodbye.
