0:00:31 > 0:00:33Staying with tennis
0:00:33 > 0:00:34and the women's singles final is happening today
0:00:34 > 0:00:35on Centre Court later.

0:00:43 > 0:00:45Marin Cilic beat Sam Querry after an exciting match yesterday

0:00:49 > 0:00:53Federer is aiming for a record-breaking
0:00:53 > 0:00:57eighth Wimbledon title.
0:00:57 > 0:00:59I feel very privileged to be in another final.
0:00:59 > 0:01:03I know how much it means to so many players to be able to go out
0:01:03 > 0:01:06on Centre Court at Wimbledon at any given time in their career and I've
0:01:06 > 0:01:09had the pleasure to play on Centre Court so many times
0:01:09 > 0:01:11and this time, in another finals, it's so good.
0:01:11 > 0:01:17I can't almost believe it's true again.
0:01:17 > 0:01:20And you might not know who to cheer on in the mixed doubles tomorrow
0:01:20 > 0:01:22because there's two British players in the mix!
0:01:22 > 0:01:25Heather Watson and her partner Henri Kontinen are the defending
0:01:25 > 0:01:29champions after winning last year, and they'll face fellow
0:01:29 > 0:01:37Brit Jamie Murray and his partner Martina Hingis, in the final.
0:01:41 > 0:01:43Next, from aces to races because Hannah Cockroft took T34
0:01:43 > 0:01:45100m gold in world-record time as Britain won three medals
0:01:45 > 0:01:48on the opening night of the World Para-athletics Championships
0:01:48 > 0:01:49at London Stadium.
0:01:49 > 0:01:5117.18 seconds was all it took for Hannah to cross the finishing
0:01:51 > 0:01:59line, and the Paralympic triple medalist is loving the atmosphere.
0:01:59 > 0:02:00Immense!
0:02:00 > 0:02:01Amazing!
0:02:01 > 0:02:04I think going around the warm-up laps, I was getting a bit emotional.
0:02:04 > 0:02:05The noise is so loud.
0:02:05 > 0:02:07We haven't had that since London 2012.
0:02:07 > 0:02:10And just to be able to go in, put a good performance in,
0:02:10 > 0:02:12it just means so much.
0:02:12 > 0:02:16And hopefully, it's a sign of a good Championships to come.
0:02:16 > 0:02:19Tackling a blaze isn't just a job for firefighters, fire dogs play
0:02:19 > 0:02:22an important role, too!
0:02:22 > 0:02:23This is Scrappy.
0:02:23 > 0:02:27He helps the fire teams in the North East of England.
0:02:27 > 0:02:29But he's now putting his paws up and retiring.
0:02:29 > 0:02:33So, who will get his job, and what does it take to be
0:02:33 > 0:02:41a brilliant fire dog?
0:02:41 > 0:02:43Meet Scrappy, County Durham and Darlington Fire Service's
0:02:43 > 0:02:44very special dog.
0:02:44 > 0:02:47He puts his special fire-protection boots on and then he's off,
0:02:47 > 0:02:49helping the firefighters.
0:02:49 > 0:02:54In fact, he's so good at his job, he's been given a special award
0:02:54 > 0:02:59by a nearby university!
0:02:59 > 0:03:03He can detect evidence up to one metre deep and 21
0:03:03 > 0:03:05days after the fire, which is really, really good!
0:03:05 > 0:03:10He's brilliant as his job, but it's time for Scrappy to retire
0:03:10 > 0:03:13and the team are looking for his replacement.
0:03:13 > 0:03:14So, what makes a good firedog?
0:03:14 > 0:03:20We like having cockers.
0:03:20 > 0:03:24They're easy to train, lightweight, good with kids,
0:03:24 > 0:03:28can go up ladders with me and can go up aerial mounts if we need
0:03:28 > 0:03:33to get into high flats.
0:03:33 > 0:03:36Well, the hunt is on, but it's not going to be easy
0:03:36 > 0:03:42finding a dog that can fill Scrappy's very special fire boots!
0:03:42 > 0:03:45It's monkey versus human now.
0:03:45 > 0:03:48The cheeky wild monkeys on Gibraltar are having a bit of a row
0:03:48 > 0:03:53with the people living there, Ayshah has more.
0:03:55 > 0:03:58Look at these lot - hanging about, being cute, monkeying around.
0:03:58 > 0:03:59Wait...
0:03:59 > 0:04:00Did he just steal food?
0:04:00 > 0:04:04The Barbary macaques are the only wild monkey left in Europe.
0:04:04 > 0:04:07Tourists love them but the people who live here...
0:04:07 > 0:04:08Not so much.
0:04:08 > 0:04:10They know how to open your car door.
0:04:10 > 0:04:12They know, when they wander down in town and you have left
0:04:12 > 0:04:15the kitchen window open, they know what a refrigerator is.
0:04:15 > 0:04:18They know how to pull the handle open and help themselves.
0:04:18 > 0:04:19Refrigerators, eh?
0:04:19 > 0:04:21I would be devo if they stole my chocolate.
0:04:21 > 0:04:24These monkeys might be troublesome but they are also rare.
0:04:24 > 0:04:28There are only 225 of them in Europe and...
0:04:28 > 0:04:31They are the last free-ranging primates in the whole of Europe.
0:04:31 > 0:04:34They are on the endangered species list and if we're not careful,
0:04:34 > 0:04:38they will disappear off the face of the Earth.
0:04:38 > 0:04:40So, to keep the peace, a charity has set up
0:04:40 > 0:04:42special feeding stations, away from homes, where the monkeys
0:04:42 > 0:04:46can get their grub.
0:04:46 > 0:04:52Let's hope they can all live together in perfect harmony.
0:04:52 > 0:04:53And take a look at this!
0:04:53 > 0:04:55There's more to this field than meets the eye.
0:04:55 > 0:04:57Ricky's on the case.
0:04:57 > 0:05:01Can you solve the mystery of the maze made from, well, maize?
0:05:01 > 0:05:03It is a curious case, but this field in Leicester has
0:05:03 > 0:05:07a collection of mysterious pathways the size of four and a half football
0:05:07 > 0:05:09pitches, and every year it has a new design in the shape
0:05:09 > 0:05:15of something special.
0:05:15 > 0:05:18It might look a bit CORN-fusing up close,
0:05:18 > 0:05:24but like every good detective, you need to look at the big picture.
0:05:24 > 0:05:27Follow the twists and turns of the case over the three miles
0:05:27 > 0:05:33of pathways, and see if you can spot a pattern emerging.
0:05:33 > 0:05:34Elementary!
0:05:34 > 0:05:38It's Sherlock Holmes.
0:05:38 > 0:05:40Over the summer, the plants will grow even taller,
0:05:40 > 0:05:41so you can easily lose your way.
0:05:41 > 0:05:44People will be able to take on the case and solve the mystery
0:05:44 > 0:05:47themselves when it opens to visitors in a few weeks' time.
0:05:47 > 0:05:53Amazing!
0:05:53 > 0:05:56That's all from me, Newsround's back right here in about half an hour.
