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