0:00:10 > 0:00:14In
0:00:14 > 0:00:16Good afternoon - I'm Hayley, and your live with Newsround.
0:00:16 > 0:00:18Here's what's happening in the world today -
0:00:18 > 0:00:21amazing footage of a baby bald eagle hatching in America.
0:00:21 > 0:00:29AndEngines at the ready - the new Formula One season fires up.
0:00:29 > 0:00:31First to Greece, where thousands of children are stranded
0:00:31 > 0:00:35on the border with Macedonia.
0:00:35 > 0:00:35Many have left their homes because of war, in the hope
0:00:37 > 0:00:40of reaching other European countries like Germany.
0:00:40 > 0:00:43But only a small amount of people are allowed over Greece's border
0:00:43 > 0:00:45each day
0:00:45 > 0:00:48European leaders have met to try to find a solution
0:00:48 > 0:00:49to the problem.
0:00:49 > 0:00:54The BBC's James Reynolds sent us this update.
0:00:54 > 0:00:57At this camp in Greece, loads and loads of kids are stuck
0:00:57 > 0:00:58here with their parents.
0:00:58 > 0:01:04They don't want to be here, they want to keep going and cross
0:01:04 > 0:01:07into the rest of Europe, where the kids get into schools
0:01:07 > 0:01:10and the mums and dads get jobs, but the border is shut
0:01:10 > 0:01:18and so everybody is stuck here in this giant camp,
0:01:18 > 0:01:21which has been built next to this railway track.
0:01:21 > 0:01:24All families live in tents they have pitched by the side
0:01:24 > 0:01:27of the train track, they have to get out of them every time
0:01:27 > 0:01:29a train comes.
0:01:29 > 0:01:31There are no schools here or lessons or
0:01:31 > 0:01:34classes, so a lot of the kids, like this one in red,
0:01:34 > 0:01:40spend their day running around finding things to do.
0:01:40 > 0:01:44something to eat, but when it rains here, it gets incredibly muddy
0:01:44 > 0:01:47and uncomfortable, and for a lot of the
0:01:47 > 0:01:57time, people wait here to work out whether or not they will get
0:01:57 > 0:01:59to cross the border or whether they will be
0:01:59 > 0:02:02told to go back.
0:02:02 > 0:02:05Blue Peter's Lindsey Russell has taken on a challenge never attempted
0:02:05 > 0:02:08before - zorbing in a giant ball across the Irish Sea for Sport
0:02:08 > 0:02:09Relief.
0:02:09 > 0:02:10But how did it go?
0:02:10 > 0:02:17Let's see.
0:02:17 > 0:02:19Lindsay, or wave runner, a star.
0:02:19 > 0:02:22I was proud but gutted at the same time.
0:02:22 > 0:02:24Tell me about the challenge.
0:02:24 > 0:02:29It was tough, it was a really long day.
0:02:29 > 0:02:39I started at five in the morning, and I was in the wave
0:02:42 > 0:02:48runner zorb for just shy of ten
0:02:48 > 0:02:48hours.
0:02:48 > 0:02:51We did 20 miles, but whether got in the way.
0:02:51 > 0:02:53Setting off was a really, really nice moment.
0:02:53 > 0:02:55We got there at 4am and people showed up.
0:02:55 > 0:03:02For me, that was moving.
0:03:02 > 0:03:06My final high was getting into the harbour, just to see my dad
0:03:06 > 0:03:08on the finish line and see all of the
0:03:08 > 0:03:09school there.
0:03:09 > 0:03:12What would you say to kids who watch what you have done
0:03:12 > 0:03:13and want to get involved?
0:03:13 > 0:03:17The point is to know you don't have to get in a ball and run
0:03:17 > 0:03:19across the Irish Sea, it can be something as small
0:03:19 > 0:03:21as going for a walk, a walk or a swim,
0:03:21 > 0:03:31and it does not matter what it is, just do something.
0:03:34 > 0:03:44And there's loads on Sport Relief if you head online now.
0:03:44 > 0:03:46Now the new Formula 1 season starts up
0:03:46 > 0:03:47this weekend in Melbourne, Australia.
0:03:47 > 0:03:50Britain's Lewis Hamilton is in pole position and looking to become four
0:03:50 > 0:03:51time world champion.
0:03:51 > 0:03:54There's a new track, a totally new team, and some
0:03:54 > 0:03:55fresh faces on the grid.
0:03:55 > 0:03:57Let's take a look.
0:03:57 > 0:04:00I'm excited and looking forward to it, the challenges I will face.
0:04:00 > 0:04:01We are all unknown.
0:04:01 > 0:04:03It will be difficult, tough challenge.
0:04:03 > 0:04:05Formula 1 begins a new season with 21 races,
0:04:05 > 0:04:07a record number, the first Grand Prix in Azerbaijan.
0:04:07 > 0:04:09Three new drivers are set to make their
0:04:09 > 0:04:16debuts.
0:04:16 > 0:04:24They will be revving up their engines.
0:04:24 > 0:04:26There is a new Briton to join.
0:04:26 > 0:04:32He has been a Newsround, telling us all about it.
0:04:32 > 0:04:34Very excited, it feels a long time coming.
0:04:34 > 0:04:36Although Mercedes may be the team to beat,
0:04:36 > 0:04:46one team smelling burning rubber will be
0:04:46 > 0:04:49Haas, with two men in the driving seat of the new team.
0:04:49 > 0:04:53Ferrari's new-car has been passed, so we will
0:04:53 > 0:04:57see at the prancing horse can meet the might of the Mercedes engine.
0:04:57 > 0:04:59In the hope of making the sport more exciting,
0:04:59 > 0:05:00bosses have introduced new animation style system,
0:05:00 > 0:05:09which will see drivers knocked out every 90
0:05:09 > 0:05:11seconds in the closing minutes of each session
0:05:11 > 0:05:12Who will win it?
0:05:12 > 0:05:14Lewis Hamilton will win the 2016 title.
0:05:14 > 0:05:15Lewis Hamilton will win.
0:05:15 > 0:05:16Lewis Hamilton.
0:05:16 > 0:05:17He is too good.
0:05:17 > 0:05:19It will be tougher for him, his main challenge
0:05:19 > 0:05:29will be Sebastian Vettel.
0:05:32 > 0:05:34Nico will win, he was on a roll in 2015.
0:05:34 > 0:05:36Everything we've seen so far suggests he really
0:05:36 > 0:05:38is getting on well.
0:05:38 > 0:05:41Lastly to this little baby bald eagle that hatched in the US
0:05:41 > 0:05:43capital, Washington, DC.
0:05:43 > 0:05:44The proud parents, known as Mr President
0:05:44 > 0:05:47and The First Lady, are the first to nest in the city's
0:05:47 > 0:05:51National Arboretum in nearly 70 years!
0:05:51 > 0:05:56A sibling should be joining it in a few days.
0:05:56 > 0:06:01That's all from me, but I'll be back nice and early tomorrow morning.
