what's up sunshine i'm Corey Wire You're
watching CNN 10 It's Thursday April 17th
Happy Friday Eve This is the 29th day of
spring and that means there are only 64
days till summer Yes please Riddle for
you today There are 30 cows in a field
28 chickens How many didn't if you know
the answer shout it out 30 cows 28
chickens How many didn't answer is 10 30
cows 28 chickens That means 10 did not
It's mathematical It's grammatical It's
a random thought Thursday Now let's get
you your 10 minutes of news We begin
today with a study from two Texas
universities They took on the question
of whether lifetime use of technology
increases reliance on devices and as a
consequence weakens cognitive abilities
over time They studied what's called the
digital dementia hypothesis analyzing 57
studies published over the last two
decades that included hundreds of
thousands of adults who were on average
68 years old when the studies began The
Alzheimer's Association defines dementia
as quote general term for loss of memory
language problem solving and other
thinking abilities that are severe
enough to interfere with daily life,"
unquote They add that Alzheimer's
disease is the most common cause of
dementia The findings of these studies
were significant None of the studies the
researchers reviewed overall correlated
an increased risk of cognitive
impairment with technology use In fact
their studies found that technology use
was actually associated with a 42% lower
risk of cognitive impairment in the
subjects involved in these studies But
the researchers also concluded that
these findings are not some sort of
green light to just start scrolling
mindlessly on your smartphone And some
of the study's limitations leave a
number of questions about the
relationships between technology use and
brain health For example there weren't
any details on whether people were using
devices in ways that meaningfully
exercise their brains or what kind of
devices they used and for how long While
technology use was generally linked with
a lower risk of cognitive decline the
authors say the findings for social
media use were inconsistent In all for
both younger and older generations
researchers say engaging with technology
in moderation is the way to go
Especially when technology helps us be
neurologically active bringing genuine
connection creativity and intellectual
stimulation to our
lives Pop quiz hot What whale name
derives from a Latin word referring to
the Roman god of the underworld humpback
whales pilot orca or beluga whales
if you said orca you're so money Also
known as killer whales their scientific
name Orsinus Orca is derived from the
Latin word orcus referring to the Roman
god of the underworld And its species
name Orca that means largebellied pot in
Latin referring to the whale's body
shape Killer whales are famous hunters
known to prey on everything from fish
like salmon to seals even other whales
and sharks But the apex predators diet
has put them at risk of toxic
contamination It can come from
pollutants like pesticides and
industrial chemicals found in their food
that can harm them physically Our Hanaco
Montgomery shows us how researchers are
using innovative AI powered tracking
technology to monitor orca's health and
improve their ecosystems
Oh good morning Roth Good morning I
assume you're looking for the pigs Yeah
I'm just creeping along here at the
Pierce Reefs in the fog Super slow I'm
sure I'll see them here in the next few
minutes Scientist Jared Towers and PhD
student Khloe Kotek are on the lookout
for
dolphins But not just any dolphins
They're looking for the largest and most
deceivingly named member of the dolphin
family the orca Also known as the killer
whale
I spent a lot of time as a kid here in
Alert Bay in the surrounding waterways
and and this area has always been a
mecca for killer whale research uh since
the 1970s So I was kind of brought up
into this
field My job basically entails keeping
track of killer whales I collect photo
identification data predation data
social and behavioral as well as genetic
data Jared has been studying whales for
about 20 years focusing mainly on the
big species also known as transients
that live in the North Pacific Ocean
Bigs killer whales or transients They
primarily feed on marine mammals like
seals porpuses dolphins sea lions and
even other whales occasionally But as
apex predators they also ingest high
concentrations of harmful contaminants
found throughout the marine food web
So when you have something like a killer
whale come along and uh eat the seal
that ate the fish then it bioaccumulates
those toxins um at a much greater rate
So that's why these mammal eating killer
wells we have on the coast here are some
of the most toxic animals on the planet
The toxic chemicals from things like
industrial waste and oil spills collect
in whales blubber which can affect their
health and the survival rates of their
offspring My hope for this work is that
by quantifying some of the effects that
contaminants are having on these killer
whales we can provide a little bit of
evidence for how we're affecting them
and that might motivate us to clean up
our act Their work relies heavily on
photo identification through digital
cameras citizen submissions and drones
Well right now I'm just waiting for
these whales to come up I'll fly over
each one of them and get a look at the
body
condition Over the last few years Jared
has been tapping into AI to help process
and organize the vast amounts of visual
data they collect So when we click on a
photo for example uh the model
suggestion automatically shows up and
then the model predicts who the
individual is And you can see that even
though this isn't a great ID photo the
model is correctly identifying this as
T90 They can then take a deeper dive and
apply other analytical tools to look at
specific parameters like calf mortality
What we're finding so far is that
individuals that are getting a higher
dose of contaminants from mom seem to
have an increased risk of mortality
before age three This research helps
provide insights not just into the
health of these killer whales but also
their ecosystem
So all the data we collect month after
month and year after year is crucial for
informing management decisions and
conservation efforts to protect these
populations in this part of the coast We
have some of the strongest viewing
guidelines and regulations when it comes
to killer wells and uh that is is one
example of a protection measure which
has been implemented over time When it
comes to killer whales I think it's it's
really important that we really make an
effort to coexist with them and find
ways that we can both live in harmony
and have successful populations moving
forward Today's story getting a 10 out
of 10 A herd of elephants who will rise
up and do anything to protect each other
When Southern California experienced a
5.2 two magnitude earthquake this week
Elephants at the San Diego Zoo sensing
some sort of danger stomped into action
moving as a unit to protect each other
Our Samantha Lindell shows us this
fascinating moment caught on
camera You're watching African elephants
try to protect one another as a 5.2
magnitude earthquake struck Southern
California Monday morning Elephants like
these at the San Diego Zoo instinctively
create what are called alert circles to
protect the herd in the face of danger
According to zoo officials elephants
have highly sensitive feet that can feel
sound making even a relatively minor
earthquake potentially stressful The zoo
says the elephants resumed normal
behavior after a few minutes but they
did stick close together
Whoa My god that was huge Buster More
than 25 million people experienced weak
to light shaking during the 5.2
magnitude quake according to the US
Geological Survey
One moral of the story find yourself a
strong herd who will be there for you
when your world gets rocked All right
superstars we got a big old shout out
today This one's going to Danville
Vermont and all our bears at the
Danville School Rise up Before we go
some food for thought from Franklin D
Roosevelt who once said quote "The only
limitation to our realization of
tomorrow will be our doubts of today."
Unquote So believe that you're going to
become that which you want to be Don't
let anyone or anything change how you
think You are more powerful than you
know I'm Coy Wire making it an awesome
day I'll see you here tomorrow for
Friday right here on CNN 10
