0:00:06 > 0:00:08Hello, you're live with me, Nel.
0:00:08 > 0:00:12Let's start with the discovery of a giant bog as big as England
0:00:12 > 0:00:15which scientists unearthed while searching a remote part of Africa.
0:00:15 > 0:00:18They think it could help uncover mysteries of nature
0:00:18 > 0:00:22going back thousands of years. Here's Ricky.
0:00:22 > 0:00:26Deep in the heart of the African rainforest, UK scientists have made
0:00:26 > 0:00:30a rather remarkable discovery, a huge area of swampland unearthed
0:00:30 > 0:00:32in the Republic of Congo.
0:00:33 > 0:00:36At 200,000 square kilometres, it's bigger than the whole of
0:00:36 > 0:00:41England and, at seven metres, deeper than an Olympic-size swimming pool.
0:00:41 > 0:00:43But the discovery wasn't easy.
0:00:43 > 0:00:45The scientists had to watch out for dwarf crocodiles,
0:00:45 > 0:00:50gorillas and elephants as they gathered samples from the area.
0:00:50 > 0:00:56To me, it was incredibly surprising to find an area the size of England
0:00:56 > 0:00:58that essentially was uncharted.
0:00:58 > 0:01:00We were walking through it in the daytime, collecting
0:01:00 > 0:01:04our samples, and then in the evening we would build platforms in the
0:01:04 > 0:01:06forest to perch little tents on.
0:01:06 > 0:01:08The land is special because it contains billions of tonnes
0:01:08 > 0:01:13of decaying vegetation called peat which is more than 10,000 years old.
0:01:13 > 0:01:17Peat bogs aren't just found in deep, remote parts of Africa.
0:01:17 > 0:01:20They're actually all around us, even here in the UK.
0:01:20 > 0:01:24This peatland in Greater Manchester is quite wet and spongy,
0:01:24 > 0:01:27as you can see, on the surface.
0:01:27 > 0:01:29It doesn't really smell that bad, either.
0:01:29 > 0:01:32And it is incredibly important for conservationists, because all
0:01:32 > 0:01:37of this has been slowly decomposing for more than 12,000 years.
0:01:37 > 0:01:41It's basically a living history that records everything that's
0:01:41 > 0:01:43happened in the area.
0:01:43 > 0:01:44They've got things like elephants, crocodiles,
0:01:44 > 0:01:49things that we don't have here, but also they've got a lot more trees.
0:01:49 > 0:01:52The scientists took samples of the Congo peat to bring back to
0:01:52 > 0:01:53the UK and test.
0:01:53 > 0:01:57They say it will help them to learn more about how
0:01:57 > 0:01:59the environment has changed over a thousand years and the Congo
0:01:59 > 0:02:03Basin's role in the world's past.
0:02:03 > 0:02:06In Ukraine, there has been serious fighting at an airport
0:02:06 > 0:02:08in the eastern city of Donestk.
0:02:08 > 0:02:13Armed groups who want Russia to have more of a say in how the country is
0:02:13 > 0:02:15run clashed with the Ukrainian army for control of the airport.
0:02:15 > 0:02:18Over the weekend, a new president was elected promising to bring
0:02:18 > 0:02:20peace to the whole country.
0:02:20 > 0:02:25But after months of unrest, the situation is still unresolved.
0:02:25 > 0:02:28Footy, and in the last hour Spurs have appointed Mauricio Pochettino
0:02:28 > 0:02:30as their new manager.
0:02:30 > 0:02:32He's left Southampton after guiding them to eighth
0:02:32 > 0:02:34in the league last season.
0:02:34 > 0:02:37He's agreed a five-year deal at the club.
0:02:37 > 0:02:40And Frozen has become the fifth biggest selling film
0:02:40 > 0:02:41in box office history.
0:02:41 > 0:02:45The Disney hit has made more than ?700 million worldwide
0:02:45 > 0:02:46since its release.
0:02:46 > 0:02:49It replaced Iron Man 3 in the all-time top five
0:02:49 > 0:02:54and is now just behind Harry Potter And The Deathly Hallows.
0:02:54 > 0:02:58That's all from me. Newsround is back tomorrow morning.
