Can a nation make a major political change without the world knowing for sure what's happened?

That's the subject of our first report today on CNN.

I'm Coral Jesus.

Thank you for watching.

North Korea is a secretive communist country.

It's government controls the media, so there's no free press there, and the news that is reported is on Lee what the government allows.

But according to South Korean intelligence, Kim Yo Jong, the sister of North Korean dictator Kim Jong UN, is increasing in power.

She now appears to be in charge of one of the most important political organizations in North Korea.

This group keeps close tabs on the ruling party's three million members to make sure they're loyal enough to the government.

It also determines political jobs, keeps the Communist Party organized and indoctrinates North Koreans with the government's ideals.

If Kim Yo Jong is now in charge of the country's organization and guidance department, it would make her the second most powerful person in the country.

But this is also raised questions about her brother's health.

Kim Jong un reportedly has an unhealthy lifestyle, he said, to be a heavy smoker, he usually keeps a grueling schedule with a lot of public appearances, but he sporadically disappeared from the public eye earlier this year without an official explanation.

Though again, that's not unusual in North Korean media in the United States.

There's a controversy right now over a possible government ban on tick tock.

The Trump administration says.

The Chinese video sharing application collects huge amounts of data from its users their Internet searches wherever they've gone with their phones and the U.

S.

Has given Tik TAKS owner until September 20th to fix the problem or possibly sell its US services to a U.

S company.

Tic TAC is suing.

It says the Trump administration didn't give the company a fair chance to defend itself and that the upcoming ban is politically motivated against China.

Tick Tock has been banned in India over its data collection practices, but the company still has an estimated 800 million monthly users around the world, including 100 million in the US alone.

CNN 10 contributor Chris James has more Tik TAKS Future is uncertain and I have urged the ticktock be closed down in America.

The video sharing app on the Chinese company that introduced it to the world are in President Trump's crosshairs.

We want no security problems with China.

It's got to be an American company is gonna be American security.

It's gotta be owned here on many other politicians and experts agree that the data Ticktock collects on its American users is unsafe in the hands of its Chinese parent company.

By dance, it is owned by a Chinese company that includes Chinese Communist Party members in leadership, and it is required under Chinese law to share user data with Beijing.

But are these security concerns a real threat?

Essentially, the concern boils down to Do you want an app installed on your phone?

If you believe that that app might ultimately be influenced by a foreign government that is directly competing with the U.

S.

Economic Tick Tock has been downloaded over two billion times across the world for years.

It's been beloved by teens, but the Cove in 19 Pandemic has helped the APP find new older audiences as well.

It's really designed for Vier ality, not for a network of acquaintances.

Also, I believe that a lot of its popularity comes from like the culture of creativity and self expression that he was able todo sister through dancing, lip sinking pranking ALS Sorts off and its central feature Before You Page, which uses an algorithm to curate an endless scroll of videos selected just for you to power it.

Tick tock.

Like any other social media, app, collects a certain amount of data on its users.

According to its privacy policy, this data informs Tik TAKS algorithms.

Among other things, Facebook collects similar information, but where that data is physically stored makes all the difference.

It's important to understand that all technology companies ultimately answer to the governments of the countries in which they exist, where they're based and where they operate.

So the same way that Facebook ultimately has to answer to the U.

S.

Government Congress, for example, can demand that Mark Zuckerberg testify.

The same applies in China, except with one major difference.

China is a far less free country and this far less protection of people's rights and people's personal information from the government.

So the issue isn't whether right now Tik TAKS feeding information to the Chinese government, it's that they potentially could be doing so if the government so wanted Congress.

The president the government really needs to create a framework for dealing with this kind of problem going forward.

There are going to be APS that are popular that come from places that are not the friendliest to the United States.

That's reality.

We need a framework for how to deal with those situations, not to deal with them one by one, after tens of millions of people already happen.

12th trivia.

What is the main ingredient in chalk board?

Chalk plaster of Paris, sodium bicarbonate, Calcium carbonate or graph i e.

Whether we're talking about Crayola or hug Romo, we're talking about chalk made with calcium carbon it.

In an era of virtual learning and Internet everything, you might be wondering why we're talking about chalk at all.

I have this chalkboard to do list at home, but only because I'm old school.

It turns out.

Not only do a number of professors still use chalk, many of them have a favorite type.

It runs about 20 bucks a box.

Can this be chalked up to personal preference?

The legend around this chalk is that it's impossible to write a false The're, um, I assume the special ingredients.

There's Angel tears.

Mathematicians from all the top schools very frequently use it.

It's a cult favorite.

As soon as I used it, I was a convert.

The chalk is one of the best kept secrets in the math world.

It's the Rolls Royce of chalk.

Hagoromo is a brand of Japanese chalk.

The way it flows on a board is a bit hard to describe in words.

It's really hard to get.

You can only get it from Japan.

You need a Japanese person to bring it back for you.

I discovered it when I went to visit the University of Tokyo, and one of the professors there said to me, You know, we have better chalk than you do in the States.

And I said, Oh, go on Chalk is chalk.

And so I tried it out, and I've I was surprised to find that he was right.

E tried it, I thought was phenomenal.

It's the densest.

It raises the cleanest that leaves the nicest line.

If you use bad talk often, you depressed really hard for anyone to see what you're writing.

So using huh?

Grandma on a good board, It doesn't really feel like you're working hard to write.

When I'm teaching, I get a feeling of energy confidence and the chalk absolutely helps.

Slowly, the math world has become aware of this, and it became a bit of a fed In some circles.

It was like maybe four years ago the word came out that the company was going out of business.

I sort of jokingly referred to it as a choc apocalypse.

So I immediately started hoarding up much as I could.

E ordered three boxes of Hungar ammo and kept in my office and use it very sparingly.

E should have bought more, but I have friends that bought boxes and boxes and boxes of the stuff they might very well be set for the rest of their career.

E got like, 1506.

That's a lot of days 46 a day.

E think I'm gonna make it you.

The original hagoromo shock is slowly disappearing.

A few years ago, ah Korean company bought their formulas and did the best job of faithfully reproducing in Korea.

It was mixed emotions.

I was happy to know that it would still be made, but I was a little disappointed that I was less clever than I thought.

I waas.

In many ways, mathematics is like craftsmanship.

In some ways, it's like artistry.

In some ways, it's like science, but there's a real chi craft side to giving a beautiful lecture on a blackboard.

Mathematicians admire this in each other and like to use the best tools for it.

There's incredible value to this, but the value isn't using it up, not hoarding it.

Rocco figure.

It is a golfer in West Virginia.

He's been playing for about a year, and he just hit his first hole in one.

The kicker Rockaways.

Four.

Get there, Get there, Get there, Get in the hole.

It did an eagle on a par three course, The shot caught on camera went viral.

And now it's the shot heard round the world, Rocco's father says.

Proud would be an understatement.

He told affiliate W.

T.

O V that though the boy is right handed, he swings with a left handed grip.

They don't plan to change that.

Why would they?

The young Iron Man is already up to par in an elite club.

Wonder if he won a prize like a new caddy.

The whole truth is that be a fair way to make the grade when your goal is straight.
