0:00:04 > 0:00:11Hi, I'm Ricky and this is Newsround.
0:00:11 > 0:00:13Should signing be taught in schools?
0:00:13 > 0:00:17And the fossil being named after Sir David Attenborough.
0:00:24 > 0:00:27First, one of the most important people in Northern Ireland has died.
0:00:27 > 0:00:29Martin McGuinness was Deputy First Minister
0:00:29 > 0:00:32of the country for ten years.
0:00:32 > 0:00:35Last night, thousands of people gathered at a candlelit vigil
0:00:35 > 0:00:41in Belfast to remember him.
0:00:41 > 0:00:43He was a significant figure who once supported violence
0:00:43 > 0:00:45in Northern Ireland but later helped bring peace there.
0:00:45 > 0:00:47Jenny's been finding out more.
0:00:47 > 0:00:50Northern Ireland - one of the four nations that make
0:00:50 > 0:00:52up the United Kingdom.
0:00:52 > 0:00:56It's a place which has been mostly peaceful for almost 20 years.
0:00:56 > 0:01:01In the years before that, life was very different.
0:01:01 > 0:01:03The country was divided and torn apart by a conflict
0:01:03 > 0:01:06known as the Troubles.
0:01:06 > 0:01:07There were bomb scares.
0:01:07 > 0:01:11If we'd maybe gone into the city centre and you would have had
0:01:11 > 0:01:12to had your bag checked.
0:01:12 > 0:01:16Thre were soldiers on the streets, there were bombs going off.
0:01:16 > 0:01:18So was it scary when you went near Belfast with your
0:01:18 > 0:01:20friends and family?
0:01:20 > 0:01:24It was and it wasn't because you became so used it to it.
0:01:24 > 0:01:26But it was scary - I can remember being in Belfast
0:01:26 > 0:01:30with my granny and I was maybe about your age and I was running
0:01:30 > 0:01:33down the street because there were explosions happening.
0:01:33 > 0:01:36You live a very different way than I did, growing up
0:01:36 > 0:01:40in Northern Ireland.
0:01:40 > 0:01:43At this time, Martin McGuiness supported violence in
0:01:43 > 0:01:47Northern Ireland as a way to bring about change.
0:01:47 > 0:01:50Martin McGuinness always wanted to achieve one thing -
0:01:50 > 0:01:52he wanted Northern Ireland to no longer be a
0:01:52 > 0:01:56part of the kingdom but instead a part of Ireland.
0:01:56 > 0:01:59When he was a young man he tried to achieve that by
0:01:59 > 0:02:01being a senior figure in something called
0:02:01 > 0:02:05the Irish Republican Army, or IRA.
0:02:05 > 0:02:09The IRA killed lots of people and frightened many more.
0:02:09 > 0:02:11But as Mr McGuinness got older he turned to
0:02:11 > 0:02:16peace and to talking, and that's why some people love him and other
0:02:16 > 0:02:18people hate him.
0:02:18 > 0:02:21But there's no doubt he is a massively important
0:02:21 > 0:02:24figure in the history of Northern Ireland and rose to be
0:02:24 > 0:02:30one of its most senior politicians - the Deputy First Minister.
0:02:30 > 0:02:33And if you want to find out more about Martin Mcguinness
0:02:33 > 0:02:37and Northern Ireland there's lots of information online.
0:02:37 > 0:02:41Now to a school in London where deaf children help to teach hearing
0:02:41 > 0:02:43children British Sign Language.
0:02:43 > 0:02:47For many of them it's a way to learn a new language and make new friend,
0:02:47 > 0:02:50but should classes like this be available in all schools?
0:02:50 > 0:03:00The guys have been telling us what they think.
0:03:20 > 0:03:24And my sister's like, what are you doing?
0:03:24 > 0:03:31And I basically just try and teach them.
0:03:40 > 0:03:42And they will understand you and you don't have to use
0:03:42 > 0:03:46your voice at all.
0:03:51 > 0:03:54Because, when you are older, if you were to go deaf or if
0:03:54 > 0:03:57you had a child that was deaf it would be easier to remember your
0:03:57 > 0:04:02signs because you would have learned it at a young age.
0:04:12 > 0:04:14He has won Baftas, Emmys and been knighted by the Queen,
0:04:14 > 0:04:18but now Sir David Attenborough has received the ultimate accolade.
0:04:18 > 0:04:22Researchers have named a 430-million-year-old fossil
0:04:22 > 0:04:23after the nature broadcaster.
0:04:23 > 0:04:27The tiny shrimp-like crustacean was discovered in ancient volcanic
0:04:27 > 0:04:30rock in Herefordshire.
0:04:30 > 0:04:36I was once a scientist but I left these things behind, science behind.
0:04:36 > 0:04:40So I'm very honoured and flattered that the professor should say such
0:04:40 > 0:04:44nice things about me now.
0:04:44 > 0:04:47And for loads more stories go to Newsround online.
0:04:47 > 0:04:50You can find out why this parrot has an infectious
0:04:50 > 0:04:56laugh, and what exactly is the cup blowing challenge?
0:04:56 > 0:04:58That's all from me, Newsround's back right
