0:00:10 > 0:00:13Good morning, I'm Ayshah with Tuesday's Newsround.
0:00:13 > 0:00:15And we're starting with a record breaker.
0:00:15 > 0:00:18An aircraft powered entirely by the sun has finished its epic
0:00:18 > 0:00:20round the world flight.
0:00:20 > 0:00:23Solar Impulse 2 touched down in Abu-Dhabi in the early
0:00:23 > 0:00:25hours of the morning.
0:00:25 > 0:00:29The journey involved 17 separate stages around the world.
0:00:29 > 0:00:31The final flight from Cairo in Egypt took more than 48 hours.
0:00:36 > 0:00:38Next up, many children around the world are forced to work -
0:00:38 > 0:00:41that means they can't do normal things like playing with their
0:00:41 > 0:00:42friends or going to school.
0:00:42 > 0:00:45This happens to thousands of children in Ghana in West Africa,
0:00:45 > 0:00:46but there is now help.
0:00:46 > 0:00:49Martin's got this.
0:00:49 > 0:00:52This is Lake Volta in Ghana.
0:00:52 > 0:00:55It's the African country's biggest fishing ground.
0:00:55 > 0:01:00About 20,000 children are being forced to work on its waters -
0:01:00 > 0:01:03some of them are sent to work by poor families in the hope
0:01:03 > 0:01:05they will have a better life.
0:01:05 > 0:01:09But they end up being made to work as fishermen,
0:01:09 > 0:01:11and treated like slaves - made to work without pay
0:01:11 > 0:01:12and stopped from leaving.
0:01:12 > 0:01:16When he was ten, Dampson was taken from his family and made to work
0:01:16 > 0:01:26as a fisherman for four years.
0:01:31 > 0:01:33TRANSLATION:
0:01:33 > 0:01:36A man came and said he was looking for someone to go
0:01:36 > 0:01:37and sell drinking water.
0:01:37 > 0:01:39My mother said I should go with him.
0:01:39 > 0:01:41I was told I had to dive with them and if I didn't,
0:01:43 > 0:01:45Dampson worked in dangerous conditions.
0:01:45 > 0:01:49Some of the boys he met were injured or died.
0:01:49 > 0:01:55Dampson was eventually rescued by a charity called
0:01:55 > 0:01:58Challenging Heights.
0:01:58 > 0:02:02He is now living with his dad and is back at school.
0:02:02 > 0:02:08Dampson is slowly rebuilding his life.
0:02:26 > 0:02:28Scientists heading to the UK's tallest mountain aren't
0:02:28 > 0:02:31packing their walking boots, they're doing it in a submarine.
0:02:31 > 0:02:32Confused?
0:02:32 > 0:02:36Leah has more.
0:02:36 > 0:02:39200 kilometres off the West Coast of Scotland,
0:02:39 > 0:02:41a submarine is heading to
0:02:41 > 0:02:49the UK's tallest mountains, hundreds of meters beneath the
0:02:49 > 0:02:51the UK's tallest mountains, hundreds of metres beneath the
0:02:51 > 0:02:52waves.
0:02:52 > 0:02:55Coral is everywhere on the mountain tops, and is teeming with
0:02:55 > 0:02:56creatures in the cold, dark waters.
0:02:56 > 0:03:00The biggest mountain is 1700 metres tall and totally submerged
0:03:00 > 0:03:07underwater.
0:03:07 > 0:03:09On-board for six weeks, scientists have controlled
0:03:09 > 0:03:13the underwater robots, watching the images streamed back.
0:03:13 > 0:03:17This is the first time that anybody has seen
0:03:17 > 0:03:19this seamount, has seen animals that live on this seamount.
0:03:19 > 0:03:21How they live, what they live on, in between,
0:03:21 > 0:03:22who lives with them.
0:03:22 > 0:03:24And that's really exciting.
0:03:24 > 0:03:26We saw some incredible things.
0:03:26 > 0:03:29Now the research ship is back, docked in Southampton.
0:03:29 > 0:03:31BBC reporter Rebecca Morelle managed to take
0:03:31 > 0:03:34a look at what samples the
0:03:34 > 0:03:36crew brought back.
0:03:36 > 0:03:39Here's a small selection of them, we've got a coral
0:03:39 > 0:03:43species that is possibly thousands of years old.
0:03:43 > 0:03:45This one can grow several metres tall and a sponge
0:03:45 > 0:03:48with tiny little creatures growing inside.
0:03:48 > 0:03:51It's going to take months to analyse all this, but even now
0:03:51 > 0:03:55the team think some of the species may be new to science.
0:03:55 > 0:04:00The researchers say these seamounts are a marine life hotspot.
0:04:00 > 0:04:03Lots of people think of the deep sea as being a
0:04:03 > 0:04:06sort of desert of mud and in fact these mountain structures are far
0:04:06 > 0:04:08from that.
0:04:08 > 0:04:12So many animals, so much life.
0:04:12 > 0:04:14Now the hard work starts, because scientists will have
0:04:14 > 0:04:17to work out what they have and what they need to
0:04:17 > 0:04:18do to protect what's
0:04:18 > 0:04:24already living on Britain's deep sea mountains.
0:04:24 > 0:04:26So that got us thinking, where would you like to
0:04:26 > 0:04:27explore if you could?
0:04:27 > 0:04:28The deepest ocean?
0:04:28 > 0:04:31Maybe a safari or some ancient ruins?
0:04:31 > 0:04:35Let us know where and why online now.
0:04:35 > 0:04:39And finally, meet Purps the penguin from Connecticut in the USA.
0:04:39 > 0:04:41She injured her left foot five years ago.
0:04:41 > 0:04:44But now, thanks to school kids and experts at an aquarium,
0:04:44 > 0:04:49they've designed a special boot for her - using a 3D printer.
0:04:49 > 0:04:52Now she can pppp-pick up her penguin feet easily!
0:04:52 > 0:04:58That's all for now, I'll be back in half an hour.
