轉承詞

Experts say there's been some activity around a North Korean missile facility, and the reason they're concerned is because North Korea hasn't tested any missiles or nuclear weapons in more than a year.

The country is going to resume doing something that the U.

Late last month in Hanoi, Vietnam, the two countries leaders met face to face for the second time.

North Korea didn't commit to getting rid of its nuclear and missile programs a priority for the U.

And America didn't commit to removing its sanctions.

Its penalties on North Korea's economy a priority for North Korea.

Still, U S President Donald Trump said he and North Korean leader Kim Jong un left the summit on friendly terms and that the door to continue discussions would stay open.

That's why possible activity at this missile sites significant.

President Trump's national security advisor says he expects North Korea to show whether it's serious about future talks with the U.

And whether the communist country is committed to giving up its nuclear program and everything that goes with it.

If it's not President Trump does not plan to remove any sanctions on North Korea.

And North Korean relations could depend on whether North Korea is using this missile site to carry out more tests.

This is a key site that North Korea was in the process off dismantling, and it now appears as though it is reassembling some of the elements there.

It is commercially available satellite imagery that has been analyzed by two groups, 38 north and also see S S on.

They both believe that it does show reassembling certain elements of Tong Shangri.

It's also Bean backed up by what we've heard from the N I s the intelligence agency here in South Korea career.

They say that they have seen that there has bean activity there.

They say that there are construction cranes they've seen vehicles in the area of roof has been put over one of the structures, a door as well s O.

Of course, the question is, why is this happening now?

Up until now, we had heard that North Korea was dismantling this.

He had talked to the South Korean president, Moon Jae, in about this.

When Kim Jong un actually met him in Pyongyang, they were discussing this.

It was part of their statement at the end of that meeting, even thinking about when they could bring independent inspectors into North Korea to prove that this site had been put out of action.

What we had no, from from 38 north, is that these satellite images are from between February 16th on March, the second eso it could have bean before, during or after the Hanoi summit.

So many analysts are reticent to say definitively that this shows that North Korea is not happy, that there was nothing at the end of that summit, that there was no agreement between US President Donald Trump on Kim Jong un.

But clearly they all agree that this is not a positive development.

Paula Hancocks, CNN Seoul Well, here's a party picture that looks kind of like postmodern art means jet planes, except it's really sort of this is a depiction of supersonic jets breaking the sound barrier.

To create the image, NASA used advanced photo technology, the kind that says allowed researchers to visualize the sound waves around the aircraft.

Ah, plane with a special imaging system flew directly above two T 38 jets, and at the very moment they broke the sound barrier, it took the picture.

Well, NASA says this is the first time that's ever been done, that it will help scientists better understand shockwaves and that it could possibly help future jets be designed to break the sound barrier without creating the loud sonic boom.

Second, which of these video game systems was released the most recently Sega Genesis Super Nintendo GameBoy or Commodore 64 Super Nintendo made its U.

Debut in 1991 making it the last system on this list to be released.

There's a new CNN hero were introducing today.

He says that when he was in first or second grade, he got a super Nintendo, and he jokes that from his parent's perspective, it was all downhill from there.

But as he got older, Zack found a way to use video games to connect with and help Children in hospitals.

That was the beginning of gamers outreach.

I always feel like they're these negative stereotypes around games and gaming culture.

Sometimes people believe that the games are corrupting the minds of America's youth, so I kind of feel more like a rebel than to get her.

So Graham, they have a list of their video games.

Kids find a source of fun and relief during stressful and difficult to create, sort of a portable video game chaos that the health care staff could use to make sure games or easy to move around.

We started calling these things go carts, so the go carts loaded up.

Right now, each unit is equipped with a council, a monitor on assortment of games controllers, and they actually move up and down for the next chapter brain play.

Any Kools that might be attached to them.

They forget about that and they just focus on the game and then they start talking to each other, you can trust me, and it was like a secret mover zone.

And who is this actually come into the hospital Ironman so they'll play games with kids.

They help solve minor tech support issues under some virtual reality.

Kind of disease I have is a pediatric cancer going on three years that many patients I started off with doing chemo chemo without anybody therapy surgery and then a bone marrow transplant.

And then radiation twice got people think the game.

We can play the game because that's way more cool than having this talk about me.

Even doctors air, sometimes now prescribing video game time.

We literally started the organization, my parent's basement.

We never really envisioned this becoming a nationwide program or even a global program, but assumes we delivered this unit.

They loved it, and it led to us getting request to build more.

We're in about 50 facilities nationwide that you talk to me a decade ago.

I don't think I would have ever seen myself building game cards.

There is no perfect ideal person to be doing this right.

I think any time you get back, just refreshing for your soul.

For today's 10 out of 10 segment, we're taking you to Snow Maze.

What Guinness World Records says is the largest sno maze on Earth.

It sits on a cornfield in Manitoba, Canada.

Its walls are six and 1/2 feet tall and two feet thick, and they're made of artificial snow, which is apparently stronger than the real thing.

It took a farmer in his staff six weeks and more than $42,000 to put it together.

A corn maze is a maze maze, but it's no mazes hazier.

You can't be any lazier or make the mais Les Mays easier.
