:00:00. > :00:00.This is Newsround on Friday the 20th of May.
:00:00. > :00:12.The tiny flying robots that have been invented in the US.
:00:13. > :00:31.Plus, what made this weatherman lose his cool.
:00:32. > :00:34.First this morning, 24 hours have passed since a plane on its way
:00:35. > :00:40.There's still no sign of it and now the RAF and the Royal Navy
:00:41. > :00:49.A search is underway to find out why a plane went missing yesterday.
:00:50. > :00:53.The EgyptAir flight was carrying 66 people on a journey
:00:54. > :00:57.from Paris in France to Cairo in Egypt, when the radars that keep
:00:58. > :01:02.track of aircrafts as they travel lost touch with it.
:01:03. > :01:05.Boats have been sent to look for any signs of wreckage
:01:06. > :01:08.in the Mediterranean Sea, where the plane went missing.
:01:09. > :01:11.No-one yet knows exactly what happened but search teams
:01:12. > :01:17.Security experts say it might have been caused by terrorism,
:01:18. > :01:20.but no-one is sure and nothing has been ruled out.
:01:21. > :01:23.Millions of flights take place every year and events like this
:01:24. > :01:29.The answer to what happened could be found in the black box -
:01:30. > :01:34.a special device which records what happens inside a plane.
:01:35. > :01:36.Investigations can be very complicated but more information
:01:37. > :01:41.is expected to be announced over the next few days.
:01:42. > :01:44.Remember, if there's anything in the news that upsets you,
:01:45. > :01:47.you can head online and take a look at our special guide for advice
:01:48. > :01:52.on what to do, and of course, we'll keep you updated on this story.
:01:53. > :01:55.Tiny flying robots that can perch on the ceiling might sound
:01:56. > :01:58.like something from a sci-fi movie, but now scientists in the US have
:01:59. > :02:04.The tiny drones are about the size of a 10p coin and they're
:02:05. > :02:08.thought to be the world's smallest winged robots.
:02:09. > :02:14.Here to tell us more is BBC reporter Victoria Gill.
:02:15. > :02:19.Thanks for joining us. Tell us, what do you think these robots can
:02:20. > :02:25.actually do? They can fly and they are very tiny.
:02:26. > :02:30.The idea is they would be usable as a swarm. They look like insects when
:02:31. > :02:34.they fly and what the robot scientists at Harbord want to do is
:02:35. > :02:40.make a horse War of them so you can carry the little sensors. If you
:02:41. > :02:46.imagine a swarm of insect robots could send over the area of a forest
:02:47. > :02:51.fire... -- Harvard. They would have a sensor to detect what is the most
:02:52. > :02:56.intensely burning area of that fire. These robots are working together.
:02:57. > :03:00.You see a lot of this. Our scientists looking at the natural
:03:01. > :03:04.word for inspiration for creating new robots?
:03:05. > :03:10.Absolutely. These are inspired by nature. When you watch them fly, you
:03:11. > :03:16.can see how insect like there. The project at Harvard Harvard is
:03:17. > :03:25.actually called robot be, because it is like a robotic be, and that is
:03:26. > :03:29.studying how insect work on a large scale. -- robotic bee. They are tiny
:03:30. > :03:35.and fragile but achieve acrobatic feats. The special little extra on
:03:36. > :03:40.this particular achievement is that they have little landing pads and a
:03:41. > :03:44.switchable electrostatic charge. That is the same charge you charge
:03:45. > :03:49.able loon with, which you could stick to the wall, with a balloon.
:03:50. > :03:54.You can switch on that landing pad so they stick and let go and fly
:03:55. > :03:56.around. I imagine scientists sticking
:03:57. > :03:58.balloons to their heads to work out how.
:03:59. > :04:01.Swimming now, and Great Britain's success at the European Swimming
:04:02. > :04:04.Ross Murdoch's gold in the 200m breaststroke was one of five medals
:04:05. > :04:07.won at London's Aquatics Centre last night, but the champ won't be
:04:08. > :04:10.competing in the event at the Rio Olympics after failing
:04:11. > :04:16.It's been a long time coming, that swim.
:04:17. > :04:19.To be that in season, to be that quick, to come away
:04:20. > :04:22.with a gold medal here, I never thought that would be
:04:23. > :04:26.happening here, so I'm absolutely delighted.
:04:27. > :04:29.I had a little bit of a bad week a few weeks ago,
:04:30. > :04:33.so it's just to prove to them that everything I do has been happening,
:04:34. > :04:36.and we are on course for the next cycle, certainly.
:04:37. > :04:39.If you're a fan of a team outside the Premier League,
:04:40. > :04:41.you might soon have fewer matches to go to.
:04:42. > :04:44.The big shake-up means there could be fewer teams
:04:45. > :04:52.The Football League wants there to be 20 teams in each
:04:53. > :04:55.They believe the change could help player development and reduce
:04:56. > :05:02.Next, an historic golf club in Scotland has voted
:05:03. > :05:06.to keep its rule that women can't be full members.
:05:07. > :05:10.Female golfers can go to the course at Muirfield but only as visitors,
:05:11. > :05:14.something that some people think is unfair and old-fashioned.
:05:15. > :05:16.Well, we want to know what you think.
:05:17. > :05:19.Should all clubs be open to both men and women?
:05:20. > :05:22.Do you think it's fair to have clubs just for one or the other?
:05:23. > :05:25.Ella's been in touch to let us know what she thinks.
:05:26. > :05:27.She says, I think women should be allowed in any
:05:28. > :05:34.Do head online and let us know your views.
:05:35. > :05:36.Finally, how do you feel about spiders?
:05:37. > :05:49.Well, a weatherman in the US has made his feelings very clear.
:05:50. > :05:51.Texas is always the national champion...
:05:52. > :05:54.A spider had crawled onto the screen during his forecast,
:05:55. > :05:58.The team behind the camera can be heard laughing at him,
:05:59. > :06:01.and luckily the weatherman saw the funny side too,
