WEBVTT 00:00:11.440 --> 00:00:13.589 Narwhals are moonlighting as climate 00:00:13.599 --> 00:00:15.589 scientists. A 91year-old pulled off a 00:00:15.599 --> 00:00:17.830 jaw-dropping agedefying feet in an 00:00:17.840 --> 00:00:20.550 ambulance powered by sunshine. Rise up 00:00:20.560 --> 00:00:23.029 sunshine. I'm Koi Wire. 10 minutes big 00:00:23.039 --> 00:00:24.950 world. Let's get you your news. We begin 00:00:24.960 --> 00:00:26.870 in London with some uplifting health 00:00:26.880 --> 00:00:29.029 news that really is a breath of fresh 00:00:29.039 --> 00:00:31.189 air. A new study suggests the British 00:00:31.199 --> 00:00:32.950 capital's efforts to cut vehicle 00:00:32.960 --> 00:00:35.350 pollution in recent years may be helping 00:00:35.360 --> 00:00:37.670 children's lungs grow healthier. 00:00:37.680 --> 00:00:39.910 Researchers focused on the city's ultra 00:00:39.920 --> 00:00:42.389 low emission zone introduced in central 00:00:42.399 --> 00:00:45.590 London in 2019. Drivers of vehicles that 00:00:45.600 --> 00:00:47.270 don't meet strict emission standards 00:00:47.280 --> 00:00:49.750 have to pay a daily charge. The idea 00:00:49.760 --> 00:00:51.910 being to put the brakes on tailpipe 00:00:51.920 --> 00:00:54.069 pollution. The study tracked thousands 00:00:54.079 --> 00:00:56.630 of kids in London and nearby Luton over 00:00:56.640 --> 00:00:58.950 several years. Before the clean air zone 00:00:58.960 --> 00:01:01.830 began, London's kids had higher exposure 00:01:01.840 --> 00:01:04.149 to traffic pollution and lower average 00:01:04.159 --> 00:01:06.310 lung function. But over the next four 00:01:06.320 --> 00:01:08.870 years, between 2018 and 2022, 00:01:08.880 --> 00:01:11.990 researchers observed a 5% drop in 00:01:12.000 --> 00:01:13.830 children with clinically impaired lung 00:01:13.840 --> 00:01:16.550 function in London. In Luton, which 00:01:16.560 --> 00:01:18.390 didn't have a clean air zone, but did 00:01:18.400 --> 00:01:20.149 make other changes like adding bike 00:01:20.159 --> 00:01:22.070 paths and lowering speed limits, the 00:01:22.080 --> 00:01:24.789 rate fell 2%. Researchers say this is 00:01:24.799 --> 00:01:26.789 the first evidence that clean air zones 00:01:26.799 --> 00:01:29.030 may actually help child development. 00:01:29.040 --> 00:01:31.190 That matters because lungs do most of 00:01:31.200 --> 00:01:33.190 their growing while we're young. If they 00:01:33.200 --> 00:01:35.270 don't fully develop by early adulthood, 00:01:35.280 --> 00:01:37.350 the risk rises later in life for 00:01:37.360 --> 00:01:39.910 conditions including asthma, emphyma, 00:01:39.920 --> 00:01:42.069 and chronic bronchitis. So, this isn't 00:01:42.079 --> 00:01:44.230 just about cleaner air today. It could 00:01:44.240 --> 00:01:47.350 mean healthier lungs for decades. 00:01:47.360 --> 00:01:49.510 Now to Nepal where nearly a week after 00:01:49.520 --> 00:01:51.190 catastrophic flooding tore through 00:01:51.200 --> 00:01:52.870 Himalayan communities, the search for 00:01:52.880 --> 00:01:54.630 the missing is becoming a race against 00:01:54.640 --> 00:01:57.190 both time and terrain. As of this 00:01:57.200 --> 00:01:59.030 taping, more than 12,200 people have 00:01:59.040 --> 00:02:01.670 died. Nearly 4,000 are still missing. 00:02:01.680 --> 00:02:03.510 Relief organizations are helping more 00:02:03.520 --> 00:02:05.590 than 80,000 residents who've been 00:02:05.600 --> 00:02:07.670 displaced. The United Nations says some 00:02:07.680 --> 00:02:09.430 of the hardest hit areas are still 00:02:09.440 --> 00:02:11.990 unable to even be contacted. Rescue 00:02:12.000 --> 00:02:14.229 crews are navigating destroyed roads, 00:02:14.239 --> 00:02:16.550 unstable mountain sides while families 00:02:16.560 --> 00:02:18.630 wait for answers. And in a place where 00:02:18.640 --> 00:02:20.390 some communities can only be reached 00:02:20.400 --> 00:02:22.790 from the sky, helicopter crews have 00:02:22.800 --> 00:02:24.949 become a lifeline. Our Anderson Cooper 00:02:24.959 --> 00:02:27.110 caught up with one trailblazing pilot 00:02:27.120 --> 00:02:29.270 helping lead that mission. Nepal's first 00:02:29.280 --> 00:02:32.390 female helicopter captain, Captain Priya 00:02:32.400 --> 00:02:33.830 Adekari. 00:02:33.840 --> 00:02:36.710 >> It's a small place where so many people 00:02:36.720 --> 00:02:38.309 went missing. It's extraordinary that 00:02:38.319 --> 00:02:41.589 you I mean the the valley is is so close 00:02:41.599 --> 00:02:44.309 and you are flying through this. It's 00:02:44.319 --> 00:02:45.270 extraordinary. 00:02:45.280 --> 00:02:47.030 >> Just imagine 20 helicopters flying on 00:02:47.040 --> 00:02:48.710 that valley. Yeah. Continuously talking 00:02:48.720 --> 00:02:50.229 with each other. That is actually a 00:02:50.239 --> 00:02:52.309 little bit of pressure to to navigate 00:02:52.319 --> 00:02:54.150 and to radio at the same time and to 00:02:54.160 --> 00:02:56.710 know where who is doing where and we 00:02:56.720 --> 00:02:58.869 going to the same place evacuating from 00:02:58.879 --> 00:03:00.309 the same place like five or six 00:03:00.319 --> 00:03:02.149 helicopters landing. So we need to talk 00:03:02.159 --> 00:03:04.229 with each other so frequently. Yeah. 00:03:04.239 --> 00:03:05.110 That is actually it. 00:03:05.120 --> 00:03:06.869 >> And now I mean you are landing in places 00:03:06.879 --> 00:03:10.790 where the ground is like liquid cement. 00:03:10.800 --> 00:03:12.309 >> Some of the places you have to be very 00:03:12.319 --> 00:03:13.589 careful because the helicopter might 00:03:13.599 --> 00:03:14.149 sink in. 00:03:14.159 --> 00:03:16.229 >> It looks from the air I imagine like to 00:03:16.239 --> 00:03:17.910 a to a novice it looks like oh it's 00:03:17.920 --> 00:03:19.430 solid ground. It's concrete. 00:03:19.440 --> 00:03:21.830 >> No it's not concrete. This thing that 00:03:21.840 --> 00:03:23.509 happened it's bigger than the earthquake 00:03:23.519 --> 00:03:25.270 we had in 2015. 00:03:25.280 --> 00:03:27.589 >> Um in during the earthquake time it was 00:03:27.599 --> 00:03:29.589 in in the different places of the 00:03:29.599 --> 00:03:31.670 Kathmandu war in Nepal. This is like in 00:03:31.680 --> 00:03:34.710 a small valley where so many people have 00:03:34.720 --> 00:03:36.630 lost life but they 00:03:36.640 --> 00:03:39.030 >> the smile I have is for the survivors. I 00:03:39.040 --> 00:03:41.030 don't know how they survived. Every time 00:03:41.040 --> 00:03:43.190 I go in land I see people around. I'm 00:03:43.200 --> 00:03:45.190 like waving at them and saying like you 00:03:45.200 --> 00:03:47.430 survived. You know the rescues that I'm 00:03:47.440 --> 00:03:48.949 doing people lying down inside my 00:03:48.959 --> 00:03:50.949 helicopter trying to open their eyes. I 00:03:50.959 --> 00:03:55.030 smile at them and say like you survived. 00:03:55.040 --> 00:03:57.350 >> Pop quiz hot shot. A narwhal's famous 00:03:57.360 --> 00:04:00.630 tusk is made up of what? bone, ivory, 00:04:00.640 --> 00:04:09.110 keratin, or pixie dust. 00:04:09.120 --> 00:04:11.350 If you said ivory, you can toot your own 00:04:11.360 --> 00:04:13.910 horn. Narwhal tus are actually overgrown 00:04:13.920 --> 00:04:15.509 teeth. Did you know? And they can grow 00:04:15.519 --> 00:04:17.590 up to 10 ft long and contain more than 00:04:17.600 --> 00:04:20.789 10 million nerve endings. Narwhals are 00:04:20.799 --> 00:04:22.550 known as the unicorns of the sea. But 00:04:22.560 --> 00:04:24.550 scientists are discovering they may also 00:04:24.560 --> 00:04:27.110 make pretty incredible oceanographers. 00:04:27.120 --> 00:04:29.110 These elusive Arctic whales are helping 00:04:29.120 --> 00:04:31.590 scientists collect data on the crucial 00:04:31.600 --> 00:04:33.590 ocean currents of a remote and hard to 00:04:33.600 --> 00:04:35.749 study corner of the planet, the rugged 00:04:35.759 --> 00:04:37.990 coast of East Greenland. Scientists 00:04:38.000 --> 00:04:40.070 fitted six narwhals with satellite 00:04:40.080 --> 00:04:41.909 transmitting sensors and tracked them 00:04:41.919 --> 00:04:43.749 for three years as they recorded things 00:04:43.759 --> 00:04:46.230 like water temperature and salinity in 00:04:46.240 --> 00:04:48.710 remote Greenland fjords. And the data 00:04:48.720 --> 00:04:51.030 are helping scientists better understand 00:04:51.040 --> 00:04:53.189 something called Atlantification. That's 00:04:53.199 --> 00:04:55.430 when warmer, saltier Atlantic water 00:04:55.440 --> 00:04:58.070 pushes farther into Arctic waters. And 00:04:58.080 --> 00:04:59.909 that matters because warmer ocean water 00:04:59.919 --> 00:05:02.230 can accelerate the melting of glaciers, 00:05:02.240 --> 00:05:04.390 which then contributes to rising sea 00:05:04.400 --> 00:05:06.950 levels. Scientists hope this new data 00:05:06.960 --> 00:05:08.469 will help them better understand the 00:05:08.479 --> 00:05:11.670 planet's ice sheet. If anybody tells you 00:05:11.680 --> 00:05:13.510 you're too old to chase a big dream, 00:05:13.520 --> 00:05:15.990 let's introduce them to Greybeard. Dale 00:05:16.000 --> 00:05:18.230 Sanders is 91 years old, and he just 00:05:18.240 --> 00:05:19.830 became the oldest person ever to 00:05:19.840 --> 00:05:22.310 complete the entire Appalachin Trail. 00:05:22.320 --> 00:05:24.950 That's roughly 2200 miles stretching 00:05:24.960 --> 00:05:27.189 from Georgia all the way to Maine. He 00:05:27.199 --> 00:05:29.430 began his journey last September and 00:05:29.440 --> 00:05:31.270 finished at top Maine's highest 00:05:31.280 --> 00:05:33.749 mountain, Mount Kataden on Monday. This 00:05:33.759 --> 00:05:35.990 wasn't Sanders first attempt at the 00:05:36.000 --> 00:05:36.629 trail. 00:05:36.639 --> 00:05:40.230 >> There is a huge, huge difference between 00:05:40.240 --> 00:05:43.990 hiking the trail at 82 years old and at 00:05:44.000 --> 00:05:47.110 91. Huge difference. But it is possible 00:05:47.120 --> 00:05:48.469 cuz I'm proving that 00:05:48.479 --> 00:05:51.110 >> it is a dangerous hike. Sanders says he 00:05:51.120 --> 00:05:53.830 fell 71 times. One fall sent him to the 00:05:53.840 --> 00:05:56.230 hospital, but Greybeard kept going. I 00:05:56.240 --> 00:05:57.670 had a chance to learn more about this 00:05:57.680 --> 00:05:59.749 trail on my own hike. Check this one 00:05:59.759 --> 00:06:00.950 out. 00:06:00.960 --> 00:06:02.870 >> It kills you physically, and you're not 00:06:02.880 --> 00:06:04.390 sleeping well and you're getting bit by 00:06:04.400 --> 00:06:07.110 bugs, ripped open feet. You just keep 00:06:07.120 --> 00:06:09.749 hiking through it. 00:06:09.759 --> 00:06:12.390 >> Hiking like this for 6 hours would be a 00:06:12.400 --> 00:06:15.189 tall task for most. But then there are 00:06:15.199 --> 00:06:17.909 people who hike this thing for 6 months. 00:06:17.919 --> 00:06:20.070 That's just mindblowing. You see this 00:06:20.080 --> 00:06:22.870 white blaze, you know you're on track. 00:06:22.880 --> 00:06:25.350 >> That white blaze is the iconic marking 00:06:25.360 --> 00:06:27.830 of the Appalachian Trail, and it guides 00:06:27.840 --> 00:06:30.629 hikers along this 2,000mi contiguous 00:06:30.639 --> 00:06:32.629 footpath running from Springer Mountain, 00:06:32.639 --> 00:06:35.510 Georgia, to Maine's Mount Kataden. I've 00:06:35.520 --> 00:06:38.550 hiked only a tiny sliver of it today. 00:06:38.560 --> 00:06:40.550 >> But I want to know more about the trail 00:06:40.560 --> 00:06:42.870 and the unique individuals like Matt, 00:06:42.880 --> 00:06:45.270 trail name Road Soda, who drop 00:06:45.280 --> 00:06:48.070 everything to conquer it. You do start 00:06:48.080 --> 00:06:50.390 to think like, why am I still doing 00:06:50.400 --> 00:06:52.150 this? 00:06:52.160 --> 00:06:54.710 >> At hikers spend most nights in tents, 00:06:54.720 --> 00:06:56.790 but hostiles like this allow them to 00:06:56.800 --> 00:06:59.110 rest up and reconnect. 00:06:59.120 --> 00:07:01.029 >> You have traies out here. It's a trail 00:07:01.039 --> 00:07:03.589 family and usually just formed by the 00:07:03.599 --> 00:07:04.950 people that are doing the same miles as 00:07:04.960 --> 00:07:07.029 you couple nights in a row. That's kind 00:07:07.039 --> 00:07:08.230 of how you create friends. 00:07:08.240 --> 00:07:09.749 >> I love this man. 00:07:09.759 --> 00:07:11.430 >> You don't see him for a couple days and 00:07:11.440 --> 00:07:12.550 then when you see him again, it's like 00:07:12.560 --> 00:07:15.189 you found your long lost friend again. 00:07:15.199 --> 00:07:16.550 You develop bonds through shared 00:07:16.560 --> 00:07:18.309 adversity. That's just it's pretty 00:07:18.319 --> 00:07:19.029 incredible. 00:07:19.039 --> 00:07:20.790 >> Throughhikers suffer through freezing 00:07:20.800 --> 00:07:23.189 cold, searing heat, rain, wind, 00:07:23.199 --> 00:07:25.749 loneliness, exhaustion, and lots of 00:07:25.759 --> 00:07:26.230 pain. 00:07:26.240 --> 00:07:28.309 >> It's a lovely shade of lilac. 00:07:28.319 --> 00:07:30.309 >> A little ibuprofen. The KG tape actually 00:07:30.319 --> 00:07:31.029 helped a lot. 00:07:31.039 --> 00:07:32.469 >> My knees have hurt pretty much the 00:07:32.479 --> 00:07:33.510 entire time. 00:07:33.520 --> 00:07:35.589 >> Three out of four throughhikers don't 00:07:35.599 --> 00:07:37.510 even make it to Maine. But those who 00:07:37.520 --> 00:07:40.390 push through the pain discover joy, 00:07:40.400 --> 00:07:43.110 pride, and maybe a new outlook on their 00:07:43.120 --> 00:07:44.950 planet and fellow humans. 00:07:44.960 --> 00:07:46.550 >> There's this like really, really strong 00:07:46.560 --> 00:07:47.270 community. 00:07:47.280 --> 00:07:49.110 >> Everybody's so on your side all the 00:07:49.120 --> 00:07:49.990 time. 00:07:50.000 --> 00:07:52.230 >> Every memory resurfaces out here cuz you 00:07:52.240 --> 00:07:54.070 just have so much time and you just look 00:07:54.080 --> 00:07:56.070 out and just see how beautiful our 00:07:56.080 --> 00:07:57.830 planet is from a different angle. 00:07:57.840 --> 00:07:59.670 >> There is hope. 00:07:59.680 --> 00:08:02.309 >> 4 months after we met him, Road Soda and 00:08:02.319 --> 00:08:04.629 his traile finally reached the top of 00:08:04.639 --> 00:08:05.430 Mount Katag. 00:08:05.440 --> 00:08:08.070 >> Oh my god. The end of one journey and 00:08:08.080 --> 00:08:10.469 perhaps the beginning of another. 00:08:10.479 --> 00:08:12.390 >> As rough as this can be, I don't want to 00:08:12.400 --> 00:08:21.430 leave this life behind. 00:08:21.440 --> 00:08:23.270 >> Today's story getting a 10 out of 10. An 00:08:23.280 --> 00:08:25.350 ambulance that runs on sunshine 00:08:25.360 --> 00:08:26.869 connecting healthc care with communities 00:08:26.879 --> 00:08:29.749 in Kenya. A team of 23 Dutch students 00:08:29.759 --> 00:08:32.389 called Solar Team Einhovven tested a 00:08:32.399 --> 00:08:34.949 prototype solarp powered medical clinic 00:08:34.959 --> 00:08:37.269 named Stella Juva. The vehicle carries 00:08:37.279 --> 00:08:39.269 equipment that can include ultrasound 00:08:39.279 --> 00:08:41.509 machines, portable X-rays, and other 00:08:41.519 --> 00:08:43.670 basic diagnostic tools to rural 00:08:43.680 --> 00:08:46.150 communities far from health facilities 00:08:46.160 --> 00:08:49.430 and unreliable electricity. The vehicle 00:08:49.440 --> 00:08:52.710 drove more than 800 km, about 500 miles 00:08:52.720 --> 00:08:54.870 through Kenya. The student team says the 00:08:54.880 --> 00:08:56.949 prototype navigated rough roads and 00:08:56.959 --> 00:08:59.430 unpaved roads successfully. So from 00:08:59.440 --> 00:09:00.870 testing in Kenya, we gathered that 00:09:00.880 --> 00:09:03.030 Stella is able to handle off-road 00:09:03.040 --> 00:09:05.269 terrain and being able to drive up to 00:09:05.279 --> 00:09:07.030 hundreds of kilometers. What we also 00:09:07.040 --> 00:09:09.430 gathered is that Stella gathers more 00:09:09.440 --> 00:09:11.509 energy from the sun than it uses with 00:09:11.519 --> 00:09:13.269 all its medical equipment on board, 00:09:13.279 --> 00:09:14.870 meaning that we can deliver continuous 00:09:14.880 --> 00:09:17.430 healthcare. The nearly 3,000lb vehicle 00:09:17.440 --> 00:09:19.670 is said to be an early demonstration 00:09:19.680 --> 00:09:22.389 project with more testing ahead. But for 00:09:22.399 --> 00:09:24.150 communities with a lack of access to 00:09:24.160 --> 00:09:25.590 health care, this solar-p powered 00:09:25.600 --> 00:09:27.990 ambulance could be a link to a brighter 00:09:28.000 --> 00:09:30.150 future. Students looked at a problem. 00:09:30.160 --> 00:09:31.750 Instead of saying somebody should fix 00:09:31.760 --> 00:09:33.829 that, they started building something. 00:09:33.839 --> 00:09:35.829 That is what we call a 10 out of 10. All 00:09:35.839 --> 00:09:38.070 right, superstars. It is shout out time. 00:09:38.080 --> 00:09:40.710 This one goes to Mrs. Devoid at Murray 00:09:40.720 --> 00:09:42.470 Middle School in Wilmington, North 00:09:42.480 --> 00:09:44.630 Carolina, who sent this incredible 00:09:44.640 --> 00:09:47.269 collection of art and cards and 00:09:47.279 --> 00:09:49.670 messages. Hi, Dora. Uh yeah, this one 00:09:49.680 --> 00:09:51.430 that's that's that's that's upside down, 00:09:51.440 --> 00:09:53.750 but that's me. Thank you guys so much 00:09:53.760 --> 00:09:55.829 for making us a part of your day. You 00:09:55.839 --> 00:09:58.070 made our day. Stay curious, stay kind, 00:09:58.080 --> 00:10:00.150 shine on, sunshine. I'm Koi Wire, and we 00:10:00.160 --> 00:10:04.040 are CNN 10.
