What's up, sunshine? I'm Ky Wire. This
is CNN 10. Happy World Coconut Day. The
coconut might be nature's Swiss Army
knife. Drink the water, eat the flesh,
make milk, oil. Uh, even the husk can be
turned into rope brushes and other
products. Talk about a fruit that's
really cocoa nuts.
10 minutes. Big world. Let's crack into
the news. We start with the end of an
era. Leon Messi, one of the greatest
players to ever touch a soccer ball, is
retiring from Argentina's national team
after more than two decades wearing his
country's colors. The decision follows
back-to-back heartbreaks for the soccer
superstar. His father, Jorge, passed
away shortly after Argentina's loss to
Spain in this year's World Cup final.
It's a bittersweet moment for fans in
Argentina who've watched the homegrown
hero rise to the pinnacle of the sport
over the years.
>> There's no comparison. At every level,
at a football level, at a personal
level, and in the national team, he gave
everything. He played the last World
Cup, 39 years old, as if he were a young
kid. He prepared himself as if he were a
young kid, knowing what was happening to
his father, too. He played it anyway for
him.
>> Absolute admiration. He left a lot for
Argentina. He went through many periods
of ups and downs.
>> Messi was for me the greatest as a
player and as a person. And his
retirement makes me sad. But on the
other hand, it doesn't displease me
because you have to retire at the top as
others did. We're going to miss him
because we all love him. In a statement
posted online, Messi thanked Argentine
fans for the love they've shown and said
he'll miss hearing them cheer from the
pitch. But if you're already missing
Messi, don't fret. The 39-year-old Messi
will still be playing for defending MLS
champions Inter Miami.
Pop quiz hot shot. How many traditional
colors make up the visible light
spectrum? Two, five, seven, or 10?
If you said seven, go ahead and
celebrate. The human eye perceives
different wavelengths on the visible
spectrum as the colors red, orange,
yellow, green, blue, indigo, and violet.
Remember the acronym Roy G. BIV. What if
we could not only see light but also
hear it? Turns out it's not as
far-fetched as it seems. And one
innovative creator is taking the
seriously bright idea to the next level
by making music. Our John Sarland got a
front row seat to hear the unique
instrument in action and learn all about
the science that makes it work.
>> Can you guess what triggers this
instrument to play music and stops it?
>> So, I made my own instrument that is
controlled by light as you can see here.
>> You heard that right. This creator has
gone viral for using tech and nature to
create music.
>> My name's Riley. I am a composer. I just
call it my light instrument.
>> So, how does it work?
>> These cables basically sense light and
how bright it is. That goes into my
breadboard that I hand soldered myself,
which then goes into my Arduino, which
is right here, that goes into my
computer.
And I have Arduino code that turns
all the stuff that's going into this
cable and it turns it into a bunch of
numbers. And then I take all those
numbers and I turn it into music.
>> In other words,
>> light go into cable, cable goes into
box, box turns it into electronics,
electronics turns it into sound.
>> Riley says the idea came about after
taking an analog synthesizer building
class using similar types of cables.
>> It sounded awful. I was like, I need to
build something kind of like this that
sounds better. I went home, coated,
started soldering and building this and
then after like 4 months I had the
instrument.
Since then, Riley says she has performed
before mostly academic audiences as well
as posting videos of herself performing
with her invention to her social media
accounts.
>> I think it's best live cuz once it is
live, you can actually like feel the
interaction. You can feel the
connection. I like to let the music
speak for itself.
>> Right now, the instrument is limited to
the original box in Riley's computer.
She says commentators have asked her how
to have one to buy, asking donations to
help her ongoing artistic project.
>> I'd love to find a way to make more
light instruments cuz people really want
to buy it. People really want to have
one of their own. So, I'd have to figure
out how to make it look nice and how to
make it not on a computer. So that's
probably like a couple years, maybe some
more sciency thinking.
Now to Chile, where some of mother
nature's most dapper dressers are
trading their tuxes for something high
tech. My vesties. Researchers have
developed special suits to help injured
penguins recover from surgery. Penguins
often arrive at rehabilitation centers
after getting tangled in fishing nets,
suffering wounds that can require
stitches. But here's the problem.
Penguins are incredibly flexible and
they can reach around and pick at those
stitches. So with prudence, researchers
at Chile's Humbult Conservation Center
helped develop a special fabric infused
with microscopic particles of copper and
zinc, which aid recovery times by
preventing bacterial growth and
promoting the formation of new blood
vessels.
>> This is a differentiator of this
technology versus others, which allows
tissues to recover faster. We're working
under the hypothesis that this
technology could also help penguin
recovery. We have tested it in dogs,
cats, mammals, but in penguins for the
first time.
>> And there's a uniquely Chilean twist
here. Chile is home to roughly 80% of
the world's remaining humbled penguin
population and is the world's largest
producer of copper. So, one of the
country's most famous natural resources
is now helping protect some of its most
famous wildlife. That's some heavy metal
healing right there. Rock on. Have you
ever found yourself crying like while
you're chopping an onion? Imagine doing
that in space where tears can float.
NASA astronaut Anneil Menon shared a
look into what cooking might look like
hundreds of miles above Earth. You might
even call it one giant leap for a meal
prep. Can
>> you tell us what's going on here?
>> We got some onions in a resupply
vehicle. We get very excited when we
have fruits and vegetables up here. So,
one of the things that we really like to
do is roast these onions. We do it with
garlic as well when we get it. We have
some aluminum aluminum foil right here.
And it's very simple. We've got our
olive oil. Place the cut onions into the
tin foil.
>> Boston.
>> I like to do a layer of this oil first
to help them stick while you're cutting
the rest.
Get them down there and package it up.
And then we'll put it over here in our
food warmer for probably like 12 24
hours cuz it's not a real oven, just a
food warmer. But over time, that will
make a nice roasted onion. They'll even
get caramelized as we go for even
longer.
Today's story getting a 10 out of 10.
One Transportation Security
Administration officer might be getting
some extra wagging rights after being
crowned the AY's top dog. The agency
announced Bolt, a three-year-old German
shorthaired pointer from Dallas Fort
Worth International Airport, is the
winner of their 2026 cutest K-9 contest.
Although he's a federal officer, Bolt
has no poker face. Look at those pearly
whites. 85 dogs nominated. But Bolt
fetched the most votes from the public
and the hearts of many nationwide. But
Bolt's job is far more than looking
cute. He's part of a TSA explosives
detection team, helping screen airports
and sniff out potential threats. That's
one dog serving looks and protecting our
airports against threats one bark at a
time. All right, it is almost time to
go, but first, congrats to our your word
Wednesday winner, our friends at
Heritage High School in White House,
Tennessee. Coach Bradley, you all
submitted prudence, the ability to use
good judgment and self-discipline to
avoid unnecessary risks. Thank you for
making us smarter today. And speaking of
your word Wednesday, I got a shout out
here to Miss Frasc and all of my friends
at Flood Middle School in Stratford,
Connecticut. They sent me this fresh
stack. It says your word Wednesday.
Thank you so much for this. And next up,
shout out goes to Miss Amy at Marshall
Middle School in the Plains, Virginia.
Thank you for all the kind letters. We
are looking forward to spending another
season with you. Remember, curiosity
helps us understand the world. Kindness
helps us change it. So, go ask a
question, make somebody smile, and shine
on sunshine. I'm Coy Wire, and we are
CNN 10.
