0:00:06 > 0:00:07Hi, I'm Ricky.
0:00:07 > 0:00:08Welcome to Newsround on Thursday morning!
0:00:08 > 0:00:10Coming up in the next few minutes:
0:00:10 > 0:00:12An amazing underwater discovery.
0:00:12 > 0:00:17One of the coldest walks to school in the world.
0:00:17 > 0:00:25A flying machine with a difference.
0:00:31 > 0:00:33First up, bad news for tennis fans.
0:00:33 > 0:00:35British number one Johanna Konta suffered a shock defeat
0:00:35 > 0:00:37at the Australian Open.
0:00:37 > 0:00:42Jo lost to world number 123 Bernarda Pera in
0:00:42 > 0:00:44the second round overnight.
0:00:44 > 0:00:49The American won in straight sets to claim her second win ever
0:00:49 > 0:00:55at a Grand Slam tournament.
0:00:55 > 0:00:58In the FA Cup, Chelsea were pushed to extra time and penalties
0:00:58 > 0:01:02in their FA Cup third round replay at home to Norwich.
0:01:02 > 0:01:04It had finished 1-1 in normal time.
0:01:04 > 0:01:06But Antonio Conte's side eventually won the shoot-out 5-3.
0:01:06 > 0:01:09Eden Hazard scored the winning penalty after his side were reduced
0:01:09 > 0:01:10to nine men in extra time.
0:01:10 > 0:01:17Chelsea face Newcastle in the next round.
0:01:17 > 0:01:20The shock of the night though came at League One side Wigan.
0:01:20 > 0:01:21They thrashed Premier League side Bournemouth 3-0.
0:01:21 > 0:01:28It means they'll now face West Ham in the fourth round.
0:01:28 > 0:01:30Now, from high in the sky to deep in the ocean.
0:01:30 > 0:01:31Fancy a dip?
0:01:31 > 0:01:34Well you might need to get your flippers on for this next one,
0:01:34 > 0:01:37and you'll definitely need to be able to hold your breath
0:01:37 > 0:01:38for a really long time.
0:01:38 > 0:01:42Because divers have made an exciting discover in the sea off
0:01:42 > 0:01:45the coast of Mexico.
0:01:45 > 0:01:49Here's more.
0:01:49 > 0:01:52This isn't just any old underwater cave.
0:01:52 > 0:01:57Oh no, this is the longest underwater cave in the world.
0:01:57 > 0:02:01A group of divers discovered it in Mexico and, it's
0:02:01 > 0:02:06over 200 miles long.
0:02:06 > 0:02:08That's the same distance from London to Paris.
0:02:08 > 0:02:11At the bottom of the cave, they found pots and relics
0:02:11 > 0:02:14belonging to Mayan people, who lived in Mexico over
0:02:14 > 0:02:15a thousand years ago.
0:02:15 > 0:02:18They hope this discovery will help them to understand more of what life
0:02:18 > 0:02:23was like for the Mayans.
0:02:23 > 0:02:26If you're walking to school in the cold and wind this morning,
0:02:26 > 0:02:29spare a thought for the children who live in this Siberian village.
0:02:29 > 0:02:32While it's pretty nippy here in the UK here it's nothing
0:02:32 > 0:02:39compared to over there.
0:02:39 > 0:02:41The people who live there call it
0:02:41 > 0:02:42"the coldest village on earth".
0:02:42 > 0:02:45And they might just be right - this week temperatures there have
0:02:45 > 0:02:46dropped to minus 62.
0:02:46 > 0:02:48That's still a bit toastier than their record low -
0:02:48 > 0:02:51five years ago it dropped even further to minus 72.
0:02:51 > 0:02:56Brrrr!
0:02:56 > 0:02:59Now, did any of you have a bath last night or maybe this morning?
0:02:59 > 0:03:03Well, we bet you didn't do this in it.
0:03:03 > 0:03:07Don't try this at home!
0:03:07 > 0:03:09Bathtubs are just for bathing, right?
0:03:09 > 0:03:13Wrong!
0:03:13 > 0:03:16People have known to race them in the past, some more
0:03:16 > 0:03:17successfully than others.
0:03:17 > 0:03:21Oh dear, but now these brothers have made themselves a flying bath tub.
0:03:21 > 0:03:22Wait, what?
0:03:22 > 0:03:25Yes.
0:03:25 > 0:03:28You've heard me right, they have built themselves a flying bath tub.
0:03:28 > 0:03:31It uses the same technologies that drones used to get airborne,
0:03:31 > 0:03:35but obviously, propellers are a bit bigger to get this
0:03:35 > 0:03:41monstrosity off the ground.
0:03:41 > 0:03:44So, how long does it take to build a flying bath tub?
0:03:44 > 0:03:47Two weeks apparently.
0:03:47 > 0:03:50Not bad really when you consider it took mankind thousands of years
0:03:50 > 0:03:51to build the first plane.
0:03:51 > 0:03:59The German government approved the project, but,
0:04:01 > 0:04:04they did ban them from going any higher than 30 metres in the air.
0:04:04 > 0:04:07So, it's unlikely they will be replacing claims any time soon.
0:04:07 > 0:04:09Shame, really.
0:04:09 > 0:04:12Finally, animal rescuers in Scotland have been busy helping this
0:04:12 > 0:04:14little hedgehog get better with a spot of swimming.
0:04:14 > 0:04:18It was found in the Scottish Highlands and couldn't
0:04:18 > 0:04:19use its back legs.
0:04:19 > 0:04:21So staff at an SSPCA rescue centre ran him a bath,
0:04:21 > 0:04:29He's been named Phelps, after the famous American swimmer.
0:04:29 > 0:04:31Just enough time to tell you to head Newsround online.
