0:00:03 > 0:00:04Good morning.
0:00:04 > 0:00:06Jenny here with news of a record breaking space rover
0:00:06 > 0:00:08on the way plus...
0:00:08 > 0:00:11We want you to send us your super handshakes and high fives.
0:00:11 > 0:00:14Keep watching.
0:00:18 > 0:00:20First this morning to a record breaking space robot.
0:00:20 > 0:00:23The Mars Rover, Opportunity, sent up to the red planet
0:00:23 > 0:00:26by American space agency Nasa ten years ago, has now travelled further
0:00:26 > 0:00:30than any other craft.
0:00:30 > 0:00:33Nasa scientists say it was only supposed to travel half a mile
0:00:33 > 0:00:36from its landing site originally, but has now clocked up 25 miles.
0:00:36 > 0:00:39It broke the previous record of 24.2 miles, held by
0:00:39 > 0:00:43Russia's Lunokhod two moon rover.
0:00:43 > 0:00:46Next to a scientific study that claims fist bumping is
0:00:46 > 0:00:48healthier than a handshake.
0:00:48 > 0:00:50Researchers at Aberystwyth University say
0:00:50 > 0:00:53the traditional handshake is the most unhygienic way to say hello.
0:00:53 > 0:00:57They used rubber gloves covered in bacteria to test different greetings
0:00:57 > 0:01:01and discovered it passes on 90% more germs than fist bumping.
0:01:01 > 0:01:06They say it could change the way we say hello.
0:01:06 > 0:01:09We're hoping that with the results of these experiments, people will
0:01:09 > 0:01:12realise that handshakes can transfer quite a lot of bacteria between
0:01:12 > 0:01:16people and that it might start becoming more socially acceptable
0:01:16 > 0:01:18to fist bump or high-five.
0:01:18 > 0:01:21Not just your mates.
0:01:21 > 0:01:24Well, that got us thinking and we want you to send us videos of what
0:01:24 > 0:01:27you think is the way to say hello.
0:01:27 > 0:01:29Head to the Newsround website to find out how to get involved.
0:01:29 > 0:01:31Ricky and I have already had a go.
0:01:31 > 0:01:33Hey. Hey, how are you doing?
0:01:37 > 0:01:42See you later. Bye.
0:01:42 > 0:01:45Now if you found some Lego washed up on a beach, you might
0:01:45 > 0:01:47think it was just good luck.
0:01:47 > 0:01:50But if hundreds of pieces started washing up on the sand you might
0:01:50 > 0:01:51start to ask questions.
0:01:51 > 0:01:52Well that's exactly what's been happening
0:01:52 > 0:01:54in Cornwall over the last 17 years.
0:01:54 > 0:01:58We sent Ayshah to investigate just what?s going on.
0:02:03 > 0:02:07I think I have found something.
0:02:07 > 0:02:12A piece of plastic, false alarm.
0:02:12 > 0:02:15This is Perranporth in Cornwall, one of the many beaches along this
0:02:15 > 0:02:19coastline where Lego has been found.
0:02:19 > 0:02:21Maggie, Charlie, Lily and Laura have been
0:02:21 > 0:02:25on the search for bits of Lego all summer.
0:02:25 > 0:02:29These are some of the Lego pieces found on Cornwall's beaches.
0:02:29 > 0:02:32Laura, you found some, which ones?
0:02:32 > 0:02:37I found all of them apart from this.
0:02:37 > 0:02:40How long could it take you to find some of the Lego pieces?
0:02:40 > 0:02:43It can take quite a while.
0:02:43 > 0:02:45But you normally come across them by accident.
0:02:45 > 0:02:48It hasn't just been washing up in the past few weeks,
0:02:48 > 0:02:51it has been going on 17 years.
0:02:51 > 0:02:54On the 13th of February 1997, a container ship called the Tokyo
0:02:54 > 0:03:00Express left Rotterdam for New York in America.
0:03:00 > 0:03:04When the boat was 20 miles of Land's End at the tip of Cornwall, it was
0:03:04 > 0:03:11hit by a freak wave and tilted 60 degrees one way and 40 degrees back.
0:03:11 > 0:03:14As a result, 62 containers fell overboard, one was carrying 5
0:03:14 > 0:03:19million pieces of Lego.
0:03:19 > 0:03:21Rob is a marine biologist and studies the movement
0:03:21 > 0:03:24of ocean waves and currents.
0:03:24 > 0:03:27It was during a storm, it would be mixed up
0:03:27 > 0:03:28and spread around, spread out.
0:03:28 > 0:03:33Some of it will have washed onto the beach but some will stay
0:03:33 > 0:03:38in the ocean for years.
0:03:38 > 0:03:41A huge ocean current goes around the UK, which will take them
0:03:41 > 0:03:44around the world.
0:03:44 > 0:03:49It is fun to fine Lego on the beach but can pose
0:03:49 > 0:03:52It is fun to find Lego on the beach but can pose
0:03:52 > 0:03:55a risk to wildlife, especially sea birds because it is dangerous.
0:03:55 > 0:03:58I haven't found any yet but there is still time before it is dark.
0:04:01 > 0:04:03In the Commonwealth Games England's Adam Gemilli grabbed
0:04:03 > 0:04:08his first major medal in the final of the men's 100m last night.
0:04:08 > 0:04:11The race was missing favourites Usain Bolt and Yohan Blake
0:04:11 > 0:04:15but it was their fellow Jamaican Keymar Bailey Cole who
0:04:15 > 0:04:17finished first in ten seconds flat.
0:04:17 > 0:04:20Gemili's grabbed an impressive second place, something he was
0:04:20 > 0:04:23pretty pleased with.
0:04:23 > 0:04:30There is so much progression that goes into running ten seconds, it is
0:04:30 > 0:04:33There is so much preparation that goes into running ten seconds, it is
0:04:33 > 0:04:37not as easy as people think. I have a great team behind me. I can't
0:04:37 > 0:04:39believe it, my first time representing England, I am so happy.
0:04:39 > 0:04:42But Para-athlete Libby Clegg was the star of the night.
0:04:42 > 0:04:45She won Scotland's first gold medal on the track in the T12 100m.
0:04:45 > 0:04:48It meant this is now Scotland's most successful Commonwealth Games ever.
0:04:48 > 0:04:51Earlier in the day, Alex Marshall and Paul Foster won
0:04:51 > 0:04:53gold in the bowls.
0:04:53 > 0:05:00That's all from me, Newsround's back right here in about half an hour.
0:05:00 > 0:05:01Be
0:05:01 > 0:05:01Be sure
0:05:01 > 0:05:01Be sure to
