Thank you for taking 10 for CNN.

10 U.

S.

Military officials are investigating a terrorist attack that happened in northern Syria Wednesday.

U.

S Central Command says four Americans were killed, two were U.

S service members.

One was a civilian with the Department of Defense and one was a D O D contractor.

The attack apparently took place while US troops were on a routine patrol in the city of Men.

Bage and the terrorist group Isis, which stands for Islamic State in Iraq and Syria, claimed it was responsible.

It said the assault was carried out by a suicide bomber wearing explosives.

The U.

S has about 2000 troops serving in Syria before Wednesday's attack.

Two American service members have been killed in action there since the current operation began in 2014.

The attack happened less than a month after U.

S.

President Donald Trump announced that American troops would leave the Middle Eastern country and that Isis was beaten badly.

Kurdish military leaders in Syria say troops can push Isis out of towns, but that northern Syria is still filled with sleeper cells.

Small groups of terrorists that live quietly in an area until they're ordered to attack.

Officials say the threat from them is very hard to get rid of.

2600 miles south in the African nation of Kenya, there was another terrorist attack this week that killed at least 21 people in the capital of Nairobi.

It started after a car bomb went off Tuesday afternoon, followed by an assault by several gunmen on a hotel complex.

This attack was claimed by al Shabaab, an Islamist militant group based in neighboring Somalia.

The assault lasted for hours before Kenyan security forces quote eliminated all the terrorists.

Dozens of people were injured and Kenya's president says more than 700 were safely evacuated.

Tourism is an important part of Kenya's economy, and terrorist attacks have hurt the industry in the past.

Second trivia, in which of these nations is Ro launch an official language Austria, Italy, Romania or Switzerland.

Herman has spoken in a region of eastern Switzerland and is one of the country's four official languages.

The World Economic Forum is getting ready to meet next week in Davos.

That's a resort in eastern Switzerland.

It's the 49th annual meeting of the group.

It brings together thousands of the world's political and business leaders.

And one big goal of the forum is to promote and develop globalization when international businesses and governments become more closely connected.

It's a controversial issue, and it's not supported by everyone who's attended The forum, High in the Swiss Alps Omit the breathtaking vistas and pristine air The devil's dream of global connective ity and cooperation is facing a bumpy ride.

Some say it may be downhill from here, but the devil sel eats the vision of Davos, which is that everybody's coming together has really been shattered over the last year.

There are so many issues facing globalization right now.

In fact, it's hard to think of something positive for globalization.

What a year.

It's bean, since the last devils from anti elite yellow vest protests in France, too populist wins at the ballot box in Brazil, Mexico and Italy on strongmen consolidating power in countries like Turkey and hungry.

It's not just America first, make America great again, right?

It's the fear of every nation out for itself.

Everywhere in Davos, you're probably going to hear a lot about a tri polar world.

U.

S is going one direction.

Europe is going another and China and some of the emerging markets are going 1/3.

But Davos won't be all doom and gloom.

Yes, global growth may be slowing, but the U.

S economy is on solid footing.

I think we're actually in a good place and certain central bankers saying they'll be patient.

The big hope, of course, The possibility of a U.

S China trade deal coming this year, too.

And there's gonna be the usual discussion about technology disruption and innovation.

After a rough 2018 it could be tough going.

Davos man on Davos Women are simply hoping to stay on their feet.

Julia Chatterley, CNN Plant burgers being burgers, Veggie burgers There's no shortage of companies trying to develop alternatives to meet what about sushi?

Specifically tuna made without tuna fish but instead from tomatoes, sesame oil and soy sauce.

Some foodies say serious sushi.

Sticklers may not spring for it, but several others have.

When it comes to seafood, are there Maur than fish in the sea?

The human population is growing exponentially.

In 1800 they were about a 1,000,000,000 people on earth.

Today there's more than seven times that on by 2100.

Estimates say there could be nearly 12 billion people around the globe.

That rapid growth comes with lots of problems.

One of the biggest or food supply may not be able to keep up when it comes to seafood.

Rising number of consumers mix with the growing popularity of foods like sushi has led to over fishing.

The Pacific bluefin tuna is a sushi staple.

Its population has fallen 97%.

Demand is only getting higher and higher and higher on DDE.

One of the big problems we have today is that, um we are over fishing tuna, and it's only at 3% at the height of its stock.

That's James Core.

Well.

He's been a chef for over 30 years, and he's the founder of a company called Ocean Hunger Foods.

His solution to the dwindling tuna population.

Tomatoes?

It's stay with me.

There's five tastes, so we have.

We're familiar with sweet, sour, salty, bitter.

But there's 1/5 taste called umami, and that refers to savory and sushi in particular.

You have soy sauce, you rice and tiny mommy.

Seaweed is high.

New Mommy, you have the tune of the tiny mom, but also that what tiny mommy or tomatoes?

The only problem was is you wouldn't have a great sushi experience if the ahi me tastes like to make it so.

The rial technology that we developed came from the process on how to remove that tomato flavour.

Keep great texture but create this kind of neutral platform, which to carry Japanese flavors or Latin American flavors or matter training basic.

Like the tomato is a vehicle to get those flavors in your mouth.

Exactly.

Ocean hugger makes plant based alternatives to seafood.

The tomato tuna is called tahini.

The companies also working on salmon made from carrots and eel made from eggplant.

Well, now let's take it.

Okay.

All right.

We're gonna depend a little.

The soy sauce, it really does look like to you.

Wow.

Yeah, that's really good.

Right now.

Let's go.

What's happenin?

Sushi roll for, uh, not very good with chopsticks.

I would totally holy grab that lunch was opposed to the regular war with the mercury.

I don't have to worry about, like, you know, killing.

Delicious.

So I was pleasantly surprised.

I mean, it actually tasted good, but if we look even further into the future, there will be less usable land to grow crops like tomatoes and carrots.

That's where some scientists think algae comes in.

Yep, algae like pond scum.

It might not sound very appetizing, but algae is actually high in protein, and it can grow where other crops can't.

All you need is sunlight, air and water.

We're not in dire need of algae based snacks just yet, but one company called nonfood wants to get ahead of the curve.

It smells.

Their first product is called non Bar, and instead of trying to emulate flavors we already know in love, they decided to embrace the algae We want to try.

This smells a little funky.

I'm not gonna lie.

I mean, it's gonna take some getting used to On Twitter, the city of Westbrook, Maine, says it looks like the moon has landed.

If you don't know what this is, will pause it for a second, so you could take a guess.

Give up.

It's an ice disk that formed in a river that passes through the city.

It's 100 yards in diameter.

It's natural, But scientists say it's pretty rare, and that this one likely rotates the way it does, because the current of the passing water pushes it that way.

So if you're where it's Briskin, you stumble on a disk.

Do not take a risk and let it take you for a whisk.

The ice is pretty thin.

You won't want to take a spin.

It may give you quite a grin, but you could fall right in.

So take it all right in.

Make our show begin again.

It's too No.

One Chagrin watched on CNN.

10.

When it comes to ice, keeping distance is quite wise.

It's far better you just view it, then maybe fall right through it.

Car lasers, and that's what we have to discuss on CNN.
