CARL AZUZ: 5G is the new G, so 3G is going like 2G.
That pretty much sums up our first story today.
I'm Carl Azuz, and let me explain.
Fifth generation or 5G is the latest
wireless technology available.
It offers faster internet speeds and better performance
than previous generations.
It has its downsides.
5G requires more cellular towers than other networks.
It may be years before some rural areas get it,
and there are always concerns about new technologies
being hacked.
But wireless providers are expanding
their 5G availability.
And when they do that, it leaves less room
on the wireless spectrum.
The radio waves that these technologies use are limited.
So what companies are doing is phasing
out 3G, their third generation technology,
to make room for 5G.
When will this happen?
AT&T will shut down its 3G network next week.
T-Mobile and Verizon will do it later this year.
Here's why this matters.
There are still devices that use 3G,
and those devices may no longer work
once the network is shut down.
Companies have been pushing people
to upgrade their 3G smartphones, e-readers, and tablets.
Some medical devices and home alarm systems may still
need to be updated and millions of cars
could be affected by this, especially
if they're more than five years old.
Vehicles that use 3G modems could have problems with GPS
and traffic information.
Those with the ability to call police if there's an accident
could fail if their software isn't upgraded
to at least 4G technology.
Some carmakers have offered fixes for this,
others reportedly haven't.
So many drivers may lose features in their cars
if they haven't upgraded them or if an update
simply isn't available.
Wireless carriers have shut down networks before.
AT&T and Verizon eliminated their 2G coverage in 2017.
10-second trivia.
Since 1924, what country has won the most
medals in the Winter Olympics--
Soviet Union, Germany, United States, or Norway?
The European nation of Norway has
the most medals overall and the most golds of any country.
And when we produced this show, Norway was leading
in those counts in these games.
But a lot of media attention has centered
on a Russian figure skater.
Olympics officials say they have a zero tolerance policy when it
comes to doping, taking certain performance enhancing
drugs that have been banned.
In December, 15-year-old Kamila Valieva tested positive
for one of these substances, but this
wasn't reported to Russia's anti-doping agency
until February.
After she helped her team win a gold medal,
Valieva was suspended from these Olympics.
But she was reinstated, allowed to compete again
after she appealed the ruling.
Valieva says her grandfather uses the drug,
and that she must have accidentally ingested it.
She'll stay on the ice while the investigation takes place.
SELINA WANG: This doping scandal around Russian figure skater
Kamila Valieva continues to cast a dark shadow
over the Olympic games as new details emerge.
15-year-old Valieva reportedly had three different substances
in her drug test sample.
These substances are all used to treat a heart condition,
but only one of the drugs is considered a banned substance.
But I spoke to the CEO of the US anti-doping agency,
who told me that all three of the drugs
have performance-enhancing capabilities,
including increasing endurance, reducing fatigue.
He said that the fact that all three of these drugs were mixed
together suggests a deliberate and sophisticated
attempt to improve performance.
CNN and Tygart reviewed a document
that showed Valieva had declared the use of two other drugs--
hypoxen and L-carnitine that are, again,
not considered banned substances,
but what Tygart says are also used to improve performance.
Now, the decision to allow Kamila
Valieva to continue to compete at these Olympics
is causing outrage.
Some former athletes, Olympians saying that this is tainting
the entire Olympic experience.
If Valieva places in the top three
this week, which she is expected to,
she will not receive a medal, the other competitors
will not receive a medal, no medals
will be awarded until a full investigation is complete.
CARL AZUZ: Lumber is getting more expensive in America.
This is the building block of new homes,
and its cost, last May, hit an all-time record high.
It's fallen sharply, then risen again since then.
And while lumber still isn't as expensive
now as it was last spring, a forest industry report
says it's triple what it was before coronavirus
took its toll.
What does that mean?
New single-family homes are almost $19,000
more expensive than they'd normally be,
according to a Home Builders Association.
Reasons for this include ongoing problems
with the supply chain of goods and challenges
in transporting wood.
Sawmills have had trouble keeping up with demand.
Other factors are biological and political.
- If the definition of inflation is too many dollars
chasing not enough goods, well, this
is what happens when too many houses chase not enough wood.
How would you characterize the price of lumber today?
JOHN RIDDLE: Volatile.
Yeah.
It is up and down.
It got to a point where we were just adding 20% to 30%
just because and hopefully, that will cover it.
- It's all they can talk about at the National Association
of Home Builders convention in Orlando
this week, starting with a sticker poll.
JERRY HOWARD: Down here is one person
who said it's been by 75%.
At a normal time, if the cost of a building material
were to increase by 75%, people would be coming unglued.
But look what it is.
Most of them are 200% or more.
- There are a few reasons why, but the problem
begins in the Canadian Rockies.
These source of almost one in every three boards
hammered into American homes and where a plague of beetles
arrived with the power to kill 100,000 trees a day.
So many, you could hear them over the phone.
JANICE COOKE: And you could actually hear the beetles
underneath the bark.
I'm listening to my trees being killed.
- Oh, my God.
Forest biologist Janice Cooke has
studied the invasion of mountain pine beetles for decades.
JANICE COOKE: Warmer over winters
and hotter, drier summers.
We saw those populations, not only rise to epidemic levels.
But in some areas, what we call, a hyper epidemic.
- Mountain pine beetles attack a single tree
like an invading army.
And to defend itself, the lodgepole pine
fills its cracks with this sticky chemical
compound we know as pitch.
Well, this turns out to be highly flammable.
So in the end, if the beatles win,
you've got a 50 foot firestarter.
Beetle-kill forest helped accelerate
those Western mega fires.
And altogether, 50 million acres have been lost up here,
an area the size of Minnesota.
JANICE COOKE: We have more than 30 mill closures
in the interior of BC alone.
Mills are not running 24/7 anymore.
- In the meantime, there is the 40-year-old trade
war with the United States.
And based on an old formula, tariffs on Canadian
would automatically doubled recently.
Joe Biden could dial those back.
But like Canada, he's also protecting more federal trees,
especially the old growth stands in places
like Tongass National Forest.
JERRY HOWARD: The Biden administration
has cut back on the harvesting of timber
on our federal lands for environmental purposes.
And so, we need more lumber from outside.
The Biden administration has not gone to the table
to negotiate a long-term deal with Canada.
So once again, we've got to look somewhere else.
In fact, we've opened up discussions
with the German government about bringing in more from Germany.
- And more builders like John Riddell in Winter Park Florida
are finding lumber alternatives.
By injecting these stackable foam molds with concrete,
he says, he creates walls 50% more energy efficient
and 100% more fireproof.
This seems to me, as we watch zoning regulations
change in California due to wildfires,
like an amazing solution.
JOHN RIDDLE: That doesn't burn. - Right.
JOHN RIDDLE: Concrete won't burn.
Now, in my mind, there is no reason
why this is not more prevalent.
JANICE COOKE: This is the business case for considering
our forests and our trees in our forests
for their entire ecosystem services
and not just the price of a 2 by 4.
CARL AZUZ: It's not every day you
meet a 15-year-old basketball player who can dunk.
Then again, it's not every day you
meet one who's 7 feet, 5 inches tall,
so the dunking thing is a footnote.
Olivier Rioux is the tallest teenager on Earth,
according to Guinness World Records.
His mom is 6'2.
His dad is 6'8.
His shoe size is 20, and all he's reportedly a strong passer
and three-point-shooter, making him a quadruple threat
on his Florida team.
It's no tall tale, small tail, fish or other false tail.
All hail, all his highness.
Maybe now's the time to sign this finest
phenom you can't short.
At the heights of high school sport,
he's the sort on the court.
Scouts will want a court, of court.
Everybody's looking up to the tallest baller they have met,
who fills the big shoes of a long legged legacy
with nothing but net.
I'm Carl Azuz, dunkin' puns and rhymes on "CNN 10."
