0:00:13 > 0:00:16Good afternoon, Ricky here with Friday's Newsround.
0:00:16 > 0:00:19First, hospitals are really busy at the moment, and lots of people
0:00:19 > 0:00:20think that's a big problem.
0:00:20 > 0:00:23So what does it mean for children who have to go there?
0:00:23 > 0:00:26Jenny's got the full story.
0:00:26 > 0:00:28It's the middle of winter, which means it's a very
0:00:28 > 0:00:31busy time of the year for the National Health Service,
0:00:31 > 0:00:32otherwise known as the NHS.
0:00:33 > 0:00:37People are worried it's now getting too busy
0:00:37 > 0:00:40and overcrowded in hospitals, and this means they're having
0:00:40 > 0:00:42to wait a really long time to be seen by a doctor.
0:00:42 > 0:00:47I've come to Sheffield Children's Hospital to meet a doctor who works
0:00:47 > 0:00:50in the emergency department to find out what's going on.
0:00:50 > 0:00:52Is it true, are hospitals getting busier, and especially
0:00:52 > 0:00:53at this time of year?
0:00:53 > 0:00:56Yes, they are getting busier, and year on year we see
0:00:56 > 0:00:59bigger numbers coming, but there is also an increase
0:00:59 > 0:01:01in the winter, which is part of the winter pressures,
0:01:01 > 0:01:04but we are prepared for those, we know they're coming.
0:01:04 > 0:01:06How does this affect children?
0:01:06 > 0:01:09If you're seriously injured, will you still get seen?
0:01:09 > 0:01:13Of course, we have a system called triage, which basically means
0:01:13 > 0:01:15sorting, so when you come through the door you're put
0:01:15 > 0:01:18into a category depending on how severe the nurse or doctor
0:01:18 > 0:01:19thinks your problem is.
0:01:19 > 0:01:21If you were to come to our department tomorrow
0:01:21 > 0:01:23and you were seriously ill or injured, you'd be
0:01:23 > 0:01:24seen straight away.
0:01:24 > 0:01:27If you came with a less urgent problem you might wait a while,
0:01:27 > 0:01:29but you would definitely get seen.
0:01:29 > 0:01:31OK, yes, hospitals are getting busier, but that doesn't
0:01:31 > 0:01:34mean that you won't get seen.
0:01:34 > 0:01:37So what's it actually like having to come into hospital?
0:01:37 > 0:01:40Meet Lily and Jake.
0:01:40 > 0:01:42Jake had to come into hospital when he thought
0:01:42 > 0:01:44he'd broken his thumb.
0:01:44 > 0:01:46And Lily came in after getting bitten by a dog.
0:01:46 > 0:01:50What's it like coming to the hospital?
0:01:50 > 0:01:54Well, when I came there weren't too many people there,
0:01:54 > 0:01:59there were a few seats taken but generally it was quite quick.
0:01:59 > 0:02:01Within ten minutes I was into the x-ray room
0:02:01 > 0:02:03with the doctors and stuff.
0:02:03 > 0:02:06It was quite a different experience for you, though, Lily.
0:02:06 > 0:02:08Can you tell us what happened?
0:02:08 > 0:02:13I got bitten by a dog out of a car window.
0:02:13 > 0:02:16It took quite a long time to get here, then it was quite busy.
0:02:16 > 0:02:18All the chairs were full up.
0:02:18 > 0:02:22There were a lot of people there because it was on a weekend
0:02:22 > 0:02:26and it took quite a long time to get seen, but I eventually did get seen.
0:02:26 > 0:02:27So, what can be done?
0:02:27 > 0:02:31Well, the Government have been criticised by doctors,
0:02:31 > 0:02:35who argue that part of the problem is that patients who are well enough
0:02:35 > 0:02:37to leave hospital can't because they aren't being given
0:02:37 > 0:02:39enough support on the outside.
0:02:39 > 0:02:42The Government say they know that hospitals are very
0:02:42 > 0:02:45busy at the moment but that, despite this, the hospitals
0:02:45 > 0:02:49are coping pretty well.
0:02:49 > 0:02:52Next, rescuers are trying to save 100 pilot whales that have
0:02:52 > 0:02:55become stranded on a beach in New Zealand.
0:02:55 > 0:03:00Around 400 of the animals became stuck and sadly
0:03:00 > 0:03:01many have died.
0:03:01 > 0:03:04Rescuers have been working through the night to try to save the rest.
0:03:04 > 0:03:07It's the worst case of this type the country has ever seen.
0:03:07 > 0:03:10It's not uncommon for these animals to become beached like this,
0:03:10 > 0:03:12but why does it happen?
0:03:12 > 0:03:14Beaching is when whales becomes stuck on sand,
0:03:14 > 0:03:17and it can be very dangerous.
0:03:17 > 0:03:19Marine scientists don't have one clear reason
0:03:19 > 0:03:20to explain why it happens.
0:03:20 > 0:03:24Here are some of the theories.
0:03:24 > 0:03:26It's thought some whales become stranded because they are sick
0:03:26 > 0:03:30or injured and pushed in shore by currents or are
0:03:30 > 0:03:34simply too old to swim.
0:03:34 > 0:03:37Whales rely on something called sonar to work out where
0:03:37 > 0:03:39they are and where they are going.
0:03:39 > 0:03:41They send out sound waves or pulses which bounce
0:03:41 > 0:03:49back off surfaces.
0:03:49 > 0:03:54Some ships use sonar pulses too which have been linked to whales
0:03:54 > 0:03:57getting stranded and marine scientists think if the two cross
0:03:57 > 0:03:59paths the whales could become confused and injured.
0:03:59 > 0:04:01It's thought changes in the environment can cause them
0:04:01 > 0:04:02to behave differently too.
0:04:02 > 0:04:04Perhaps food stocks are low, temperatures are unusually
0:04:04 > 0:04:07high or low or the water they are in has become polluted.
0:04:07 > 0:04:08And even whales make mistakes.
0:04:08 > 0:04:10It's thought they can sometimes lose their way into shallow waters
0:04:10 > 0:04:14by accident while travelling to warmer waters to mate.
0:04:14 > 0:04:16Whales are very sociable creatures and often travel
0:04:16 > 0:04:18in large pods or groups.
0:04:18 > 0:04:22But marine scientists think if one is affected by any of the last four
0:04:22 > 0:04:30reasons then others travelling with it will copy them.
0:04:30 > 0:04:33After 112 years Dippy the Dinosaur has finally left his home
0:04:33 > 0:04:37at the Natural History Museum in London.
0:04:37 > 0:04:41He had to be taken apart bone by bone by a team of six people and,
0:04:41 > 0:04:44just in case you're wondering, that's 292 bones in total,
0:04:44 > 0:04:46so it took them quite a bit of time.
0:04:46 > 0:04:48He will now be cleaned and repaired before starting
0:04:48 > 0:04:51a tour of the UK in 2018.
0:04:51 > 0:04:52Goodbye for now, Dippy.
0:04:52 > 0:04:57That's all from me.
