:00:00. > :00:09.It's Thursday afternoon. Ayshah here with the biggest news and sport
:00:10. > :00:13.stories of the day. Coming up: A shocking discovery for scientists.
:00:14. > :00:16.And not many seats left - the latest on the battle of the backsides.
:00:17. > :00:23.This is Newsround. First up, Britain's Paralympic
:00:24. > :00:27.curling team have made it to the semi-finals of the competition.
:00:28. > :00:30.Aileen Neilson's team got through to the final four, despite losing their
:00:31. > :00:34.latest match to China, after other results went their way. This morning
:00:35. > :00:40.the GB curlers battled back from 5-1 down to beat the USA 8-7, in a
:00:41. > :00:46.nail-biting finish. Next, to the mystery that's baffled
:00:47. > :00:48.scientists for years. How do animals know to avoid electricity pylons?
:00:49. > :00:52.Well, a team of international scientists believe they've had a
:00:53. > :00:55.breakthrough and it's all down to UV light, something humans can't even
:00:56. > :01:01.see. Leah's got more on the shocking discovery.
:01:02. > :01:08.Electricity pylons are all over the UK. We know to avoid them because of
:01:09. > :01:12.how dangerous they can be. While wild animals learn to adapt to
:01:13. > :01:15.obvious dangers around them, like a busy road, how they knew how to
:01:16. > :01:25.avoid the static structure of a plyon was a bit puzzling for
:01:26. > :01:30.scientists. For many years it has been known that many mammals do not
:01:31. > :01:35.like going near roads or power lines. The roads were a barrier, but
:01:36. > :01:39.power lines were not. They could walk under But what they realised
:01:40. > :01:41.was that these UV lights, or sparks, filmed on a special camera, were
:01:42. > :01:44.scaring animals off. A power line with no problem. They
:01:45. > :01:48.tested almost 40 different species by showing them normal light and UV
:01:49. > :01:50.light, and found the UV light was most distracting.
:01:51. > :01:58.They also found more species than ever can pick up UV light, like
:01:59. > :02:02.reindeer and farm animals. What we want to do is to make the power
:02:03. > :02:09.industry aware of this problem so they can take this on board when
:02:10. > :02:13.they planned new power cables. So not only has an age old mystery
:02:14. > :02:15.been pretty much unlocked, it's also given electricity companies more
:02:16. > :02:18.information for planning where pylons are put up.
:02:19. > :02:21.Thanks, Leah. All this week on Newsround we've
:02:22. > :02:23.been showing you the ground-breaking technology behind the next wave of
:02:24. > :02:26.robots. Now, researchers are developing machines based on some of
:02:27. > :02:30.the smallest and fastest creatures on planet earth. Ricky went to meet
:02:31. > :02:31.the scientists who are creating robots by looking very closely at
:02:32. > :02:52.these. Ants. We have entered this new and
:02:53. > :02:55.exciting phase in robotics where the technology is taking inspiration
:02:56. > :03:05.from nature around us, and from us humans, too. We are now trying to
:03:06. > :03:11.make robots which will work in the real world, which is a messy, untidy
:03:12. > :03:14.place. The world is full of amazing animals and creatures who get on
:03:15. > :03:20.perfectly well in the real world. They provide us with not only
:03:21. > :03:27.inspiration, but fantastic designs. Tell us about the swarm. It is meant
:03:28. > :03:32.to behave like an ant. The collection robots are the entire
:03:33. > :03:38.colony of robots. It is designed to model the way that the ants forage
:03:39. > :03:43.for food. Some scientists argue there is not much point in basing a
:03:44. > :03:47.robot on a human being because we are too complex, so they turned
:03:48. > :03:56.their attention to robots inspired by biology, things like and is, a
:03:57. > :03:59.grasshopper, and even a flea. There are plenty of people still
:04:00. > :04:03.interested in robots that look and behave like people but many of us
:04:04. > :04:06.realise that most robots that we really need in the real world don't
:04:07. > :04:10.need to look like people and it's probably best if they don't.
:04:11. > :04:13.Head over to the website to see our amazing pictures of robots that have
:04:14. > :04:16.been inspired by animals. And while you're there check out the gallery
:04:17. > :04:18.of your techno-tastic robot designs you've been sending in.
:04:19. > :04:22.Next, all this week football pundits Alan Shearer and Robbie Savage are
:04:23. > :04:26.putting their bottoms on the line for charity, literally. The pair are
:04:27. > :04:30.having to race round to be the first to sit on half the seats in Wembley
:04:31. > :04:34.Stadium. That's 45,000 seats each. It's all for Sport Relief and
:04:35. > :04:37.they're trying to raise ?500,000. They have until tomorrow to finish.
:04:38. > :04:41.Good luck, guys! Finally, head over to the website to
:04:42. > :04:44.find out all about the battle over where the remains of Richard III
:04:45. > :04:47.should be buried, a story we've followed since the ancient king's
:04:48. > :04:51.remains were found in a Leicester car park in 2012.
:04:52. > :04:56.That's all. I'm back 6.50pm. See ya.
