The next time I see you is on January 6th 2020 and I want to thank all of you who tweeted me that you would have watched on Christmas, though I'm not sure you're being completely truthful.

And remember Santa Claus is watching you.

Carla Zeus for CNN 10 In August of 2016 an American graduate student named Shi Wei Wang was arrested in Take Ron, the capital of Iran.

He was doing research there at the time and studying the Farsi language, but Iran sentenced him to 10 years in prison, saying his school, Princeton University, had sent Wong to Iran to get secret information about the country.

Princeton said that was completely false.

Two years later, the United Nations said there was no legal reason why Wong was arrested and imprisoned, and on Saturday the Trump administration announced that one was in good spirits after arriving at a U.

S.

Army Medical Center in Germany.

This was part of a prisoner exchange on the same day that Wong arrived in Germany on Iranian stem cell.

Scientist was pictured flying back to his home country alongside Iran's foreign minister.

The scientists name is Massoud Soul Amani.

He was arrested in Chicago, Illinois, in the fall of last year and found guilty of breaking trade laws concerning Iran.

That country, says Sulamani, had not committed any crime.

An interesting part of all this is how it happened.

The U.

S and Iran are rivals.

They don't have diplomatic relations.

Officials from the two countries don't regularly talk to each other.

Both the White House and the Iranian government thanks Switzerland for its assistance in the negotiations.

The U.

S government official says the Trump administration hopes this will lead to more success with Iran.

There are other Americans being held in the Middle Eastern country.

The U.

S government says it won't rest until every American who has been detained there and around the world is brought back home.

National memorials at Pearl Harbor, Hawaii, include the USS Arizona and what other ship?

USS Utah, Oklahoma, California, West Virginia.

So it's only open to the American military.

The USS Utah Memorial also rests at Pearl Harbor, which will live in infamy, huh?

United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan?

No, that made Saturday the 78th anniversary of the attack on Pearl Harbor.

And one of the American sailors who survived the bombings and explosion of the USS Arizona was laid to rest there on this Pearl Harbor Day.

Lauren Bruner died on September 10th of this year.

He was almost 99 years old, and his loved ones gathered Saturday at the USS Arizona Memorial to remember him and passed his remains to US Navy divers who placed them near one of the Arizona's gun turrets.

Bruner was the second toe last man to escape from the sinking ship, and the memorial spokeswoman says he'll be the last survivor toe have This done is only three people who were aboard the Arizona in 1941 are still alive, and the others plan to be laid to rest with their families when it was carried out.

The Japanese attack on Pearl Harbor was the deadliest attack on American soil, and in the days that followed, the United States joined China, Great Britain and the Soviet Union in their fight against Germany, Italy and Japan.

The struggle of the Second World War.

Up next away, artificial intelligence could be used to save land and lives.

Simply put, a I is using computers to accomplish tasks that people normally do.

It's already sprung up all around us when you look up how to translate a sentence from English to Spanish when an application picks out new songs or movies or clothes for you based on something you like.

When Alexa or Google or cirie answers questions about everything from the weather to the best way to get somewhere, these are examples of a I in action.

And while there are privacy concerns about having your every move or statement monitored, the technology is rapidly changing the ways many people live.

Can it help protect them from danger?

Smokey the Bear is a U.

S Forest Service character that has told people for decades on Lee.

You can prevent forest fires or wildfires.

Could artificial intelligence also play a role in 2018 California saw the largest and deadliest wildfires in its history.

The notorious campfire spread it a rate of 80 football fields per minute.

That means detecting wildfires as early as possible and responding quickly have become essential to thwarting a potentially deadly disaster.

And one startup says it's found a way to spot fires just minutes after they spark from the image being captured in space.

Tow us producing an alert.

It's about nine minutes.

Start to finish.

Based in Santa Fe, New Mexico, Dick Art Labs uses cloud based artificial intelligence to analyze huge swaths of real time satellite imagery and identify fires.

We decided to focus on satellite imagery just because there's so much of it, and this means there's lots and lots of data about the planet.

Today.

Fire authorities most often rely on human spotters to report a blaze, but day carts ai ai platform scans thermal imagery from Noah satellites toe Look for what the company calls heat anomalies when this turns out to be a pretty challenging problem, because the temperature of the earth is always changing and we basically seek out these hot spots by modeling what the Earth would look like if there wasn't a fire there and then comparing that to the image that we get from the ghost 16 and 17 satellites, and if we noticed a big discrepancy, that's a pretty good indicator that there's a fire there.

The company says it's already pinpointed exact locations for 4700 fires and is currently testing a wildfire alert system with the local forestry division.

In New Mexico, D Cards sees a future where it could help fire authorities in other states.

To think that Kincaid fires is a good example of how this technology could change how we respond to fires.

In October 2019 the Kincaid Fire started in Sonoma County, California, and went on to scorch more than 77,000 acres of land.

Company says it generated an alert before most people even knew the fire existed.

We detected it about 10 minutes after it started.

It was a lot more challenging for people because this fire started at around 9 30 at night.

It wouldn't be until half an hour after we had already broadcast our alert that Cal Fire would have AH plane over the fire and another few hours until he actually reported it publicly to the team.

It's evidence of the systems advantage over human spotters.

Of course, to really make an impact, the technology will need to integrate with firefighting authorities that can respond to the fires on the ground.

It's all about making sure that less fires slip through the cracks and go on to become these massive mega fires.

Cos ambitions don't stop there.

It's currently using the same technology to find methane leaks in oil fields and scan crops in Africa to identify potential food shortages.

Other companies are working on similar technology as well.

There's lots of different ways you can apply this AI ai technology at scale and try to monitor the Earth and try to stop problems before they become much, much bigger.

Thing is a perfect 10 at a 10 idea.

Let's put this electric eel The work.

The animal at the Tennessee Aquarium is named Miguel Watson.

He's the electric eel, and somehow engineers harnessed his shocks to power the lights of a nearby Christmas tree.

When he's just swimming around looking for food, the lights blink a little when he gets excited or he eats the tree really lights up.

When we met, it glows like nobody's business.

When he hears his favorite Christmas song, you'll be home for Christmas.

Ah, Holly, Jellied Christmas.

We need a little fish, Miss Elise, Na'vi Dodd.

It's beginning to look a lot like crustaceans.

Let it blow, Let it blow, let it blow I'm dreaming of a wet Christmas silver eels and, of course, every eels undisputed favorite shocking around the Christmas tree up Carlos, and he'll be back tomorrow on CNN.
