00:00:11.440 --> 00:00:13.270
What's up, sunshine? I'm Ky Wire. This

00:00:13.280 --> 00:00:16.390
is CNN 10. Happy World Coconut Day. The

00:00:16.400 --> 00:00:17.990
coconut might be nature's Swiss Army

00:00:18.000 --> 00:00:19.910
knife. Drink the water, eat the flesh,

00:00:19.920 --> 00:00:22.470
make milk, oil. Uh, even the husk can be

00:00:22.480 --> 00:00:23.990
turned into rope brushes and other

00:00:24.000 --> 00:00:25.429
products. Talk about a fruit that's

00:00:25.439 --> 00:00:27.990
really cocoa nuts.

00:00:28.000 --> 00:00:29.910
10 minutes. Big world. Let's crack into

00:00:29.920 --> 00:00:32.229
the news. We start with the end of an

00:00:32.239 --> 00:00:34.310
era. Leon Messi, one of the greatest

00:00:34.320 --> 00:00:36.389
players to ever touch a soccer ball, is

00:00:36.399 --> 00:00:38.389
retiring from Argentina's national team

00:00:38.399 --> 00:00:40.630
after more than two decades wearing his

00:00:40.640 --> 00:00:42.630
country's colors. The decision follows

00:00:42.640 --> 00:00:44.630
back-to-back heartbreaks for the soccer

00:00:44.640 --> 00:00:46.869
superstar. His father, Jorge, passed

00:00:46.879 --> 00:00:49.029
away shortly after Argentina's loss to

00:00:49.039 --> 00:00:51.750
Spain in this year's World Cup final.

00:00:51.760 --> 00:00:53.670
It's a bittersweet moment for fans in

00:00:53.680 --> 00:00:56.069
Argentina who've watched the homegrown

00:00:56.079 --> 00:00:58.549
hero rise to the pinnacle of the sport

00:00:58.559 --> 00:01:00.470
over the years.

00:01:00.480 --> 00:01:02.630
>> There's no comparison. At every level,

00:01:02.640 --> 00:01:04.390
at a football level, at a personal

00:01:04.400 --> 00:01:06.870
level, and in the national team, he gave

00:01:06.880 --> 00:01:08.630
everything. He played the last World

00:01:08.640 --> 00:01:11.350
Cup, 39 years old, as if he were a young

00:01:11.360 --> 00:01:14.070
kid. He prepared himself as if he were a

00:01:14.080 --> 00:01:16.230
young kid, knowing what was happening to

00:01:16.240 --> 00:01:18.789
his father, too. He played it anyway for

00:01:18.799 --> 00:01:19.510
him.

00:01:19.520 --> 00:01:22.390
>> Absolute admiration. He left a lot for

00:01:22.400 --> 00:01:24.950
Argentina. He went through many periods

00:01:24.960 --> 00:01:26.390
of ups and downs.

00:01:26.400 --> 00:01:28.390
>> Messi was for me the greatest as a

00:01:28.400 --> 00:01:30.710
player and as a person. And his

00:01:30.720 --> 00:01:33.429
retirement makes me sad. But on the

00:01:33.439 --> 00:01:35.590
other hand, it doesn't displease me

00:01:35.600 --> 00:01:37.910
because you have to retire at the top as

00:01:37.920 --> 00:01:40.390
others did. We're going to miss him

00:01:40.400 --> 00:01:42.710
because we all love him. In a statement

00:01:42.720 --> 00:01:44.870
posted online, Messi thanked Argentine

00:01:44.880 --> 00:01:46.950
fans for the love they've shown and said

00:01:46.960 --> 00:01:49.109
he'll miss hearing them cheer from the

00:01:49.119 --> 00:01:51.510
pitch. But if you're already missing

00:01:51.520 --> 00:01:53.830
Messi, don't fret. The 39-year-old Messi

00:01:53.840 --> 00:01:56.230
will still be playing for defending MLS

00:01:56.240 --> 00:01:59.749
champions Inter Miami.

00:01:59.759 --> 00:02:01.830
Pop quiz hot shot. How many traditional

00:02:01.840 --> 00:02:03.510
colors make up the visible light

00:02:03.520 --> 00:02:13.190
spectrum? Two, five, seven, or 10?

00:02:13.200 --> 00:02:15.589
If you said seven, go ahead and

00:02:15.599 --> 00:02:17.270
celebrate. The human eye perceives

00:02:17.280 --> 00:02:19.350
different wavelengths on the visible

00:02:19.360 --> 00:02:21.350
spectrum as the colors red, orange,

00:02:21.360 --> 00:02:23.830
yellow, green, blue, indigo, and violet.

00:02:23.840 --> 00:02:27.030
Remember the acronym Roy G. BIV. What if

00:02:27.040 --> 00:02:29.350
we could not only see light but also

00:02:29.360 --> 00:02:31.110
hear it? Turns out it's not as

00:02:31.120 --> 00:02:32.949
far-fetched as it seems. And one

00:02:32.959 --> 00:02:34.869
innovative creator is taking the

00:02:34.879 --> 00:02:37.430
seriously bright idea to the next level

00:02:37.440 --> 00:02:40.229
by making music. Our John Sarland got a

00:02:40.239 --> 00:02:41.830
front row seat to hear the unique

00:02:41.840 --> 00:02:44.229
instrument in action and learn all about

00:02:44.239 --> 00:02:49.589
the science that makes it work.

00:02:49.599 --> 00:02:51.030
>> Can you guess what triggers this

00:02:51.040 --> 00:02:54.229
instrument to play music and stops it?

00:02:54.239 --> 00:02:55.910
>> So, I made my own instrument that is

00:02:55.920 --> 00:02:59.110
controlled by light as you can see here.

00:02:59.120 --> 00:03:01.030
>> You heard that right. This creator has

00:03:01.040 --> 00:03:03.670
gone viral for using tech and nature to

00:03:03.680 --> 00:03:04.630
create music.

00:03:04.640 --> 00:03:07.589
>> My name's Riley. I am a composer. I just

00:03:07.599 --> 00:03:09.350
call it my light instrument.

00:03:09.360 --> 00:03:10.470
>> So, how does it work?

00:03:10.480 --> 00:03:13.110
>> These cables basically sense light and

00:03:13.120 --> 00:03:16.309
how bright it is. That goes into my

00:03:16.319 --> 00:03:18.790
breadboard that I hand soldered myself,

00:03:18.800 --> 00:03:21.990
which then goes into my Arduino, which

00:03:22.000 --> 00:03:25.190
is right here, that goes into my

00:03:25.200 --> 00:03:26.949
computer.

00:03:26.959 --> 00:03:30.630
And I have Arduino code that turns

00:03:30.640 --> 00:03:32.949
all the stuff that's going into this

00:03:32.959 --> 00:03:35.350
cable and it turns it into a bunch of

00:03:35.360 --> 00:03:39.190
numbers. And then I take all those

00:03:39.200 --> 00:03:41.910
numbers and I turn it into music.

00:03:41.920 --> 00:03:42.789
>> In other words,

00:03:42.799 --> 00:03:47.110
>> light go into cable, cable goes into

00:03:47.120 --> 00:03:51.509
box, box turns it into electronics,

00:03:51.519 --> 00:03:53.430
electronics turns it into sound.

00:03:53.440 --> 00:03:55.830
>> Riley says the idea came about after

00:03:55.840 --> 00:03:57.910
taking an analog synthesizer building

00:03:57.920 --> 00:04:00.470
class using similar types of cables.

00:04:00.480 --> 00:04:02.470
>> It sounded awful. I was like, I need to

00:04:02.480 --> 00:04:04.630
build something kind of like this that

00:04:04.640 --> 00:04:07.509
sounds better. I went home, coated,

00:04:07.519 --> 00:04:10.070
started soldering and building this and

00:04:10.080 --> 00:04:13.509
then after like 4 months I had the

00:04:13.519 --> 00:04:16.789
instrument.

00:04:16.799 --> 00:04:18.949
Since then, Riley says she has performed

00:04:18.959 --> 00:04:21.430
before mostly academic audiences as well

00:04:21.440 --> 00:04:23.830
as posting videos of herself performing

00:04:23.840 --> 00:04:25.990
with her invention to her social media

00:04:26.000 --> 00:04:26.629
accounts.

00:04:26.639 --> 00:04:28.790
>> I think it's best live cuz once it is

00:04:28.800 --> 00:04:30.390
live, you can actually like feel the

00:04:30.400 --> 00:04:31.830
interaction. You can feel the

00:04:31.840 --> 00:04:34.310
connection. I like to let the music

00:04:34.320 --> 00:04:35.990
speak for itself.

00:04:36.000 --> 00:04:37.749
>> Right now, the instrument is limited to

00:04:37.759 --> 00:04:39.909
the original box in Riley's computer.

00:04:39.919 --> 00:04:41.909
She says commentators have asked her how

00:04:41.919 --> 00:04:44.390
to have one to buy, asking donations to

00:04:44.400 --> 00:04:46.790
help her ongoing artistic project.

00:04:46.800 --> 00:04:49.350
>> I'd love to find a way to make more

00:04:49.360 --> 00:04:51.830
light instruments cuz people really want

00:04:51.840 --> 00:04:53.430
to buy it. People really want to have

00:04:53.440 --> 00:04:55.670
one of their own. So, I'd have to figure

00:04:55.680 --> 00:04:58.070
out how to make it look nice and how to

00:04:58.080 --> 00:05:01.749
make it not on a computer. So that's

00:05:01.759 --> 00:05:04.310
probably like a couple years, maybe some

00:05:04.320 --> 00:05:10.070
more sciency thinking.

00:05:10.080 --> 00:05:11.990
Now to Chile, where some of mother

00:05:12.000 --> 00:05:13.670
nature's most dapper dressers are

00:05:13.680 --> 00:05:15.590
trading their tuxes for something high

00:05:15.600 --> 00:05:17.830
tech. My vesties. Researchers have

00:05:17.840 --> 00:05:19.990
developed special suits to help injured

00:05:20.000 --> 00:05:22.790
penguins recover from surgery. Penguins

00:05:22.800 --> 00:05:24.870
often arrive at rehabilitation centers

00:05:24.880 --> 00:05:26.950
after getting tangled in fishing nets,

00:05:26.960 --> 00:05:28.629
suffering wounds that can require

00:05:28.639 --> 00:05:30.310
stitches. But here's the problem.

00:05:30.320 --> 00:05:32.550
Penguins are incredibly flexible and

00:05:32.560 --> 00:05:34.150
they can reach around and pick at those

00:05:34.160 --> 00:05:36.790
stitches. So with prudence, researchers

00:05:36.800 --> 00:05:39.670
at Chile's Humbult Conservation Center

00:05:39.680 --> 00:05:41.990
helped develop a special fabric infused

00:05:42.000 --> 00:05:44.310
with microscopic particles of copper and

00:05:44.320 --> 00:05:46.790
zinc, which aid recovery times by

00:05:46.800 --> 00:05:48.310
preventing bacterial growth and

00:05:48.320 --> 00:05:49.749
promoting the formation of new blood

00:05:49.759 --> 00:05:50.790
vessels.

00:05:50.800 --> 00:05:52.310
>> This is a differentiator of this

00:05:52.320 --> 00:05:54.390
technology versus others, which allows

00:05:54.400 --> 00:05:57.110
tissues to recover faster. We're working

00:05:57.120 --> 00:05:58.710
under the hypothesis that this

00:05:58.720 --> 00:06:00.629
technology could also help penguin

00:06:00.639 --> 00:06:02.950
recovery. We have tested it in dogs,

00:06:02.960 --> 00:06:05.270
cats, mammals, but in penguins for the

00:06:05.280 --> 00:06:06.550
first time.

00:06:06.560 --> 00:06:08.390
>> And there's a uniquely Chilean twist

00:06:08.400 --> 00:06:11.430
here. Chile is home to roughly 80% of

00:06:11.440 --> 00:06:13.270
the world's remaining humbled penguin

00:06:13.280 --> 00:06:15.510
population and is the world's largest

00:06:15.520 --> 00:06:17.110
producer of copper. So, one of the

00:06:17.120 --> 00:06:19.029
country's most famous natural resources

00:06:19.039 --> 00:06:21.350
is now helping protect some of its most

00:06:21.360 --> 00:06:23.590
famous wildlife. That's some heavy metal

00:06:23.600 --> 00:06:26.390
healing right there. Rock on. Have you

00:06:26.400 --> 00:06:28.390
ever found yourself crying like while

00:06:28.400 --> 00:06:30.629
you're chopping an onion? Imagine doing

00:06:30.639 --> 00:06:33.749
that in space where tears can float.

00:06:33.759 --> 00:06:36.390
NASA astronaut Anneil Menon shared a

00:06:36.400 --> 00:06:38.150
look into what cooking might look like

00:06:38.160 --> 00:06:40.309
hundreds of miles above Earth. You might

00:06:40.319 --> 00:06:42.309
even call it one giant leap for a meal

00:06:42.319 --> 00:06:43.029
prep. Can

00:06:43.039 --> 00:06:44.550
>> you tell us what's going on here?

00:06:44.560 --> 00:06:46.390
>> We got some onions in a resupply

00:06:46.400 --> 00:06:47.990
vehicle. We get very excited when we

00:06:48.000 --> 00:06:49.990
have fruits and vegetables up here. So,

00:06:50.000 --> 00:06:51.430
one of the things that we really like to

00:06:51.440 --> 00:06:53.749
do is roast these onions. We do it with

00:06:53.759 --> 00:06:55.909
garlic as well when we get it. We have

00:06:55.919 --> 00:06:58.550
some aluminum aluminum foil right here.

00:06:58.560 --> 00:07:00.469
And it's very simple. We've got our

00:07:00.479 --> 00:07:04.150
olive oil. Place the cut onions into the

00:07:04.160 --> 00:07:05.430
tin foil.

00:07:05.440 --> 00:07:06.070
>> Boston.

00:07:06.080 --> 00:07:08.710
>> I like to do a layer of this oil first

00:07:08.720 --> 00:07:10.230
to help them stick while you're cutting

00:07:10.240 --> 00:07:12.309
the rest.

00:07:12.319 --> 00:07:13.830
Get them down there and package it up.

00:07:13.840 --> 00:07:15.510
And then we'll put it over here in our

00:07:15.520 --> 00:07:18.390
food warmer for probably like 12 24

00:07:18.400 --> 00:07:20.070
hours cuz it's not a real oven, just a

00:07:20.080 --> 00:07:21.990
food warmer. But over time, that will

00:07:22.000 --> 00:07:24.950
make a nice roasted onion. They'll even

00:07:24.960 --> 00:07:26.790
get caramelized as we go for even

00:07:26.800 --> 00:07:32.629
longer.

00:07:32.639 --> 00:07:34.309
Today's story getting a 10 out of 10.

00:07:34.319 --> 00:07:35.830
One Transportation Security

00:07:35.840 --> 00:07:37.749
Administration officer might be getting

00:07:37.759 --> 00:07:39.909
some extra wagging rights after being

00:07:39.919 --> 00:07:42.629
crowned the AY's top dog. The agency

00:07:42.639 --> 00:07:45.350
announced Bolt, a three-year-old German

00:07:45.360 --> 00:07:47.189
shorthaired pointer from Dallas Fort

00:07:47.199 --> 00:07:49.990
Worth International Airport, is the

00:07:50.000 --> 00:07:53.990
winner of their 2026 cutest K-9 contest.

00:07:54.000 --> 00:07:56.230
Although he's a federal officer, Bolt

00:07:56.240 --> 00:07:59.270
has no poker face. Look at those pearly

00:07:59.280 --> 00:08:02.390
whites. 85 dogs nominated. But Bolt

00:08:02.400 --> 00:08:04.550
fetched the most votes from the public

00:08:04.560 --> 00:08:06.869
and the hearts of many nationwide. But

00:08:06.879 --> 00:08:09.029
Bolt's job is far more than looking

00:08:09.039 --> 00:08:11.749
cute. He's part of a TSA explosives

00:08:11.759 --> 00:08:14.550
