COY WIRE: Hello, everyone.
It's Thursday.
Happy Friday Eve to you.
It's your boy, Coy.
And I'm thankful to be hanging out with you right here
this week on "CNN 10."
It's time to say goodbye to summertime because today
is officially the first day of fall, also
called autumnal equinox.
Let's take 10 to break it all down.
During the vernal and autumnal equinox
is the sun is directly over the equator,
so day and night are considered to be the same length.
If you reside in the northern hemisphere,
you know it as the start of fall.
But folks down south of the equator, this equinox
is actually the start of spring.
This is not to be confused with a solstice though.
Those are in the summer and the winter
and represent the longest and shortest
days of the year respectively.
So when it comes to fall, you might be thinking about colder
temperatures, pumpkin spice latte, some football,
or falling leaves.
And speaking of leaves, let's take
a minute to learn why they actually
change color in the fall.
[MUSIC PLAYING]
PEDRAM JAVAHERI: I want you to think
about leaves on a tree as essentially many solar panels.
What they're able to do is fascinating.
They are taking the sunlight in.
And through a process known as photosynthesis,
they're able to transfer the sun's energy
and create a chemical known as chlorophyll.
Now, chlorophyll is key because it
gives the leaves its green colors
during the long summer months.
But beneath the surface, the leaves
actually always have the reds, the oranges,
the yellows in place.
While chlorophyll is there, it's there and it's green.
While it's taken away in the shorter days and shorter months
of autumn, now you're releasing some of the true colors
back to the surface.
Of course, weather can play a role
in this as well, especially in the vibrancy of it.
When you have plenty of rainfall in the growing season
or in the spring season, they're able to get
plenty of good colors in early September,
October, and November.
If you have extreme heat, extreme drought
in place, maybe a freeze--
early snow storm or even strong winds,
certainly that can do damage, the leaves
will not be there for you to see them in peak foliage.
So hopefully, you have a chance to get out there this year
and enjoy the fall colors.
COY WIRE: Continuing our constitutional theme
10-second trivia this week, which branch of the US
government is mentioned first in the Constitution,
the executive, judicial or the legislative?
The answer is legislative.
The branch's powers are laid out in Article
I of the US Constitution.

Next up today, Call to Earth is looking
at how to protect and conserve our planet by listening to it.
Today, we're headed to the rainforest hinterlands
of the Gold Coast in Queensland, Australia, where a scientist is
using a network of sound-recording devices
and artificial intelligence to track down an endangered
and elusive species of bird.
[MUSIC PLAYING]
DANIELLA TEIXEIRA: Behind us here is Purling Brook Falls.
And on the other side of this escarpment,
you can actually see how the vegetation changes.
COY WIRE: For the past seven years the research
of acoustic ecologist, Dr. Daneilla Teixeira
has focused on recording and analyzing
the sounds of Australia's iconic black-cockatoos.
DANIELLA TEIXEIRA: So we actually
have sound recorders planted in that forest over there.
COY WIRE: She says the birds face a multitude of threats,
including habitat loss and climate change
and that their dwindling numbers,
low density, and cryptic nature make them really hard to find.
DANIELLA TEIXEIRA: Just having a bit of a look.
You're much more likely to see this feeding
sign than you are actually to see the birds themselves.
With the particular project that we're doing today,
this is programmed to record every single day
from sunrise to sunset.
COY WIRE: With all of those hours of recordings to analyze,
she also relies heavily on artificial intelligence.
DANIELLA TEIXEIRA: What we're looking at here
is the detections of glossy black-cockatoos
that the machine learning has detected.
[BIRD CAWING]
So that's what they sound like.
COY WIRE: With her research, Daneilla
says they now have a complete understanding of the bird's
vocalizations and can even train the AI to identify
the most exciting moments of a cockatoo's life
leaving the nest.
DANIELLA TEIXEIRA: Fledging is the moment when
the baby bird leaves the nest.
And I've been able to train algorithms to help
me detect that automatically.
And that's how we can actually detect breeding success
and measure it in really big ways.
COY WIRE: About 1,800 kilometers northeast of Gold Coast
sits the Yourka Reserve, a remote parcel
of land owned and managed by Bush Heritage Australia.
Daneilla also works as a researcher
for this conservation-minded organization.
DANIELLA TEIXEIRA: Yourka is situated in what we consider
to be a resilient landscape.
So it's likely to offer refugia from climate
change in the future for quite a large number of species.
COY WIRE: Just under a year ago, four
new solar-powered recording stations were installed here.
And today, she is back to collect
the data for the first time.
DANIELLA TEIXEIRA: Look how nice and dry it is in there.
COY WIRE: The sensors are part of the Australian Acoustic
Observatory, a world first continent-wide network,
consisting of approximately 360 devices that record 24/7.
DANIELLA TEIXEIRA: The sound recorders that we've put out
here on Yourka Reserve have been out there during times where
the site was inaccessible.
So it would have been collecting sound data when we weren't
even able to go out there.
Hopefully, we find some threatened species,
some frogs, some birds.
And we can actually get a bit of an idea of how
the ecosystems are performing.
COY WIRE: Daniella believes that a noisy landscape
is a healthy landscape.
And that her recordings, what she calls digital fossils,
can be a key to unlocking a new level
of understanding about Australia's natural world.
DANIELLA TEIXEIRA: There's a whole world
of activity happening right now that we
would just be unaware of.
But sound is the best way that we can connect to that.
But if we understand what those sounds mean,
we can understand these species and what they need.

COY WIRE: For 10 out of 10 today, tips
and tactics for greatness from two
of the greatest athletes of all time.
I recently caught up with Tampa Bay Bucs star QB Tom Brady
and F1 star Lewis Hamilton to find
out what's pushed them to become the best time and time again.
You both are strikingly similar.
I mean, you both wear helmets to work.
You're both very driven-- you're in the driver's seat--
leading a team of people.
You have to make split seconds decisions
with huge implications.
What is something that you may see in each other, something
innate within each of that you have in common that
has propelled you to greatness?
LEWIS HAMILTON: I think probably the things we have in common is
that sheer grit, that focus, that drive to be better,
you know, that, yes, better than you were yesterday,
and precision.
COY WIRE: There you go.
Attention to detail.
LEWIS HAMILTON: With your precision, man.
COY WIRE: Tom, you'll appreciate this.
Six months ago, I talked to Lewis.
And you may not remember this, but before we started,
there was a tiniest thread on his pants
and he asked for some scissors to cut it.
And it hit me in that moment, I was like, this is a man who
pays attention to the details.
Like, how you do anything is how you do everything, right?
TOM BRADY: Yeah.
COY WIRE: Can you relate to that when it comes to that precision
Lewis is talking about?
TOM BRADY: What I've really been inspired
about Lewis over a period of time is you always see--
everyone thinks it's just Lewis in the car,
but he recognizes it's the everyone
behind the scenes that are allowing
him to be successful as well.
And I've seen him when he wins, and he
gives credit to everyone.
And I've seen when he loses, you know, how he doesn't--
there's never blame associated with the two.
So I always feel like our best moments in life
come when we're facing our most difficult challenges.
COY WIRE: Your average career is like three and a half years.
Lewis, I played nine years.
I have a titanium plate, four screws in my neck.
I thought that was good.
This was going to this 23rd season.
Both of you, though, just iconic high level of operation
for decade, more, right?
So what keeps you going?
What drives you?
What is it?
TOM BRADY: For me, it's always just been trying to--
I always feel like no one cares about what you did in the past.
You know, you have to be motivated
to be your best this year.
Everyone is showing up to buy season tickets for this season,
not for what happened last year or two seasons ago.
And I feel like, when people make the commitment to you,
in the end, you want to fulfill that
what they're coming to see.
People want to come and see me do great.
They want to see Lewis do great.
They follow their sports heroes and their favorite sports teams
because they want to see you the thrill of victory.
And I feel like I want to-- when I make that commitment to play,
it's a kind of all encompassing commitment.
COY WIRE: The greatest of all time, the goats.
There's some bad men.
You all are the greatest, too.
We love all the love we're getting on the comment
section at youtube.com/cnn10, so we're showing some love back.
Huge shout out to Mannheim Middle School
in Melrose Park, Illinois.
Tomorrow is Fri-yay.
Can't wait.
Crush it today and be awesome.
I'm Coy.
Thanks for watching "CNN 10."
