0:00:16 > 0:00:16Here
0:00:16 > 0:00:16Here is
0:00:16 > 0:00:17Here is your
0:00:17 > 0:00:17Here is your web
0:00:17 > 0:00:17Here is your web stay
0:00:17 > 0:00:18Here is your web stay Newsround.
0:00:18 > 0:00:19First to a very talented chap.
0:00:19 > 0:00:22No, not this fella - but Paddington writer Michael Bond.
0:00:22 > 0:00:25Today he died at the age of 91, but I don't think his creation
0:00:25 > 0:00:27will ever leave our screens.
0:00:27 > 0:00:29Michael's first book was published almost 50 years ago,
0:00:29 > 0:00:34it then became a TV series and a film in 2014.
0:00:34 > 0:00:37He was inspired by a teddy bear he saw in a shop window.
0:00:37 > 0:00:40But don't worry, there's still more Paddington to come as a sequel
0:00:40 > 0:00:43to the movie will be out next year.
0:00:43 > 0:00:46Next, chatting to friends online or on social media can be fun,
0:00:46 > 0:00:49but a new feature from Snapchat has got people worried that we could be
0:00:49 > 0:00:50sharing too much information.
0:00:50 > 0:00:52I've been finding out more.
0:00:52 > 0:00:54Snapchat is a popular way to contact your friends online
0:00:54 > 0:00:57and send them pictures showing what you're up to.
0:00:57 > 0:01:00But recently a new feature has been added.
0:01:00 > 0:01:02It shows people where you are in the world.
0:01:02 > 0:01:06The Snap Map shows a user's bitmoji, their cartoon avatar
0:01:06 > 0:01:09within Snapchat, pinpointed on a world map.
0:01:09 > 0:01:12Users can then zoom into the map to see the exact
0:01:12 > 0:01:14location of their friends.
0:01:14 > 0:01:16It is worrying that Snapchat are encouraging users
0:01:16 > 0:01:18to share their location through the app, potentially
0:01:18 > 0:01:20with everyone on their contact list.
0:01:20 > 0:01:23The NSPCC wouldn't recommend that anyone shares their location,
0:01:23 > 0:01:26particularly with people they don't know.
0:01:26 > 0:01:29And that's why we are calling for all young people to be able
0:01:29 > 0:01:31to have safer accounts, with privacy settings
0:01:31 > 0:01:32set as default.
0:01:32 > 0:01:35What young people can do with Snapchat is actually use
0:01:35 > 0:01:37a setting called ghost mode, which allows them to
0:01:37 > 0:01:38hide their location.
0:01:38 > 0:01:40And we would encourage all young people to do that.
0:01:40 > 0:01:42It's really, really simple to setup.
0:01:42 > 0:01:45If you turn on ghost mode, you can still see your friends,
0:01:45 > 0:01:47but they won't be able to see whereabouts you are.
0:01:47 > 0:01:52When in photo taking mode, pinch the screen to open Snap Map.
0:01:52 > 0:01:55Touch the setting cog in the top right corner of the screen,
0:01:55 > 0:01:59and tap ghost mode to switch off the location sharing.
0:01:59 > 0:02:01A spokesperson for Snapchat has told us...
0:02:15 > 0:02:17Over 100 million people use Snapchat all over
0:02:17 > 0:02:18the world, every single day.
0:02:18 > 0:02:21But if you want to make sure your friends don't know
0:02:21 > 0:02:26exactly where you are, then turn the location off.
0:02:26 > 0:02:28Fatbergs!
0:02:28 > 0:02:30The super gross collections of fat that join together
0:02:30 > 0:02:37and clog up our sewers - ewww!
0:02:37 > 0:02:40Well, it's gone from yuck to useful as this sewer fat is now
0:02:40 > 0:02:42being turned into something a lot more valuable.
0:02:42 > 0:02:43Jenny's got this one.
0:02:43 > 0:02:48Deep below our feet in the sewers underground, something nasty lurks.
0:02:50 > 0:02:53When people pour fat and grease from cooking down the drain,
0:02:53 > 0:02:59the fat clumps together to create massive horrible fatbergs!
0:02:59 > 0:03:01Some fatbergs are huge and can create big problems,
0:03:01 > 0:03:07costing water companies a lot of money to clear away.
0:03:07 > 0:03:09That's about four foot deep down there.
0:03:09 > 0:03:11But now this sewer sludge is about to be changed
0:03:11 > 0:03:13into something really valuable.
0:03:13 > 0:03:17A fuel company is going around sucking up the fatbergs.
0:03:17 > 0:03:22They're then taken to a special processing plant where they can be
0:03:22 > 0:03:25turned into a type of car fuel called biodiesel.
0:03:25 > 0:03:28So we've collected a fatberg from a water company sewer.
0:03:28 > 0:03:34The vehicle's travelled down, he's come to side, he's now tipping.
0:03:34 > 0:03:36There's a lot of solids in this one so, actually,
0:03:36 > 0:03:39he's using the tipping truck to tip that in there.
0:03:39 > 0:03:42This is where we receive all those raw materials to turn into biofuel.
0:03:42 > 0:03:44The fat gets heated, pumped and filtered,
0:03:44 > 0:03:49removing all the sludge and slime.
0:03:49 > 0:03:53So we've removed all of the solids, all of the liquids and we're left
0:03:53 > 0:03:55with a clean oil that looks a little bit like this.
0:03:55 > 0:03:56From this...
0:03:56 > 0:03:58To this.
0:03:58 > 0:04:00Pretty remarkable!
0:04:00 > 0:04:03Biodiesel is way cleaner for the environment than regular
0:04:03 > 0:04:13diesel, and this plant can make up to 90 million litres a year.
0:04:13 > 0:04:14But are there enough slimy fatbergs around?
0:04:14 > 0:04:16I guess it's difficult to say.
0:04:16 > 0:04:19As a part of the trial we've been taking about 30 tonnes
0:04:19 > 0:04:20a week out of Birmingham.
0:04:20 > 0:04:23That's 30 tonnes of fatberg from just Birmingham every week.
0:04:23 > 0:04:27I don't know whether to be disgusted or impressed.
0:04:27 > 0:04:30So from yuck to useful.
0:04:30 > 0:04:34Fatbergs are being turned into something pretty nifty.
0:04:36 > 0:04:41Finally, who's up for a little live moo-sic?!
0:04:41 > 0:04:46Five-year-old Bella decided to entertain these cows
0:04:46 > 0:04:48with her ukelele whilst on holiday at her grandparents'
0:04:48 > 0:04:50caravan, in Wales.
0:04:50 > 0:04:53She built up quite an audience.
0:04:56 > 0:04:57That's all from me.
0:04:57 > 0:04:58Newsround's back tomorrow with Jenny.
0:04:58 > 0:05:00Bye for now.
0:05:04 > 0:05:07Hi, guys, we've important news for you today. So important.
0:05:07 > 0:05:10Really important. Extremely important. Incredibly important.
