Wake up.

Today is the first day, Thursday, October 1st, and we have some top-notch headlines for you.

I am Koy Waer.

This is CNN 10.

Let's get started.

We start at the White House, where a key meeting took place at the intersection of politics and technology.

The biggest figures in the field of artificial intelligence gathered this week with President Donald Trump to discuss the risks of the rapid development of AI models.

The leaders of OpenAI, Anthropic, Meta, and other major AI players have signed a commitment aimed at better self-monitoring of their models.

The meeting came after a series of events that raised concerns about AI security, including cases where AI agents went rogue and attempted to hack federal databases.

And just this week, chipmaker Nvidia announced a new software platform designed to stop such “uncontrolled” agents from operating beyond human control.

Our Claire Duffy will tell you more about what this could mean for the industry.

The launch of this security product seems entirely consistent not only with Nvidia's existing business.

The company already provides most of the chips and software for AI, and this also aligns with Nvidia CEO Jensen Huang's stance on AI security.

Huang largely dismissed these existential fears about AI and uncontrollable agents, saying it all comes down to better control over the technology.

And that's actually what the software that Nvidia is introducing will do.

It will monitor and contain AI agents used by companies, ensure compliance with internal policies, and shut them down if they try to go beyond their assigned tasks .

All of this is very important for Nvidia's business, as the company is counting on a further boom in AI development.

So if we see a slowdown—whether due to regulation or companies voluntarily deciding to cut back on development— it could directly impact Nvidia's business.

We'll see how much this is confirmed in the coming weeks and months.

Six Flags Magic Mountain announces that it is permanently closing one of its most famous attractions—the X2 roller coaster.

The sudden announcement comes about a month after a CNN investigation uncovered a history of head injuries, hospitalizations and even deaths linked to the ride.

Here is part of Kyung La's investigation into the controversial roller coaster .

It's not about a lawsuit.

Michael Wilkes finds it hard to fathom how so many people like him claim to have been injured at Six Flags Magic Mountain on a roller coaster called X2.

He suffered a severe cerebral hemorrhage and had to abandon the cause of his life—his career as a lawyer.

I sincerely hope that by talking about this, changes will still happen.

This is my goal.

That's why I'm here today.

Wilkes' attorneys announced that more than 100 people plan to sue Six Flags.

Three lawsuits have already been filed, but many more say they were seriously injured on this ride.

Oho!

A first reported on two women who fainted immediately after riding the X2 roller coaster at Magic Mountain this summer.

They were admitted to the same hospital the same week, and both women underwent emergency surgeries for similar brain hemorrhages.

Pam Gillen was at Magic Mountain with her daughter Camilla, celebrating her 16th birthday on July 5.

This lasted seconds.

You come in as a normal person, and when you come back, you're already in critical condition.

It happened because of the roller coaster.

That's right.

Six days later, then-25- year-old Naomi Greer Wilkinson boarded the X2 roller coaster.

She fainted after getting off the ride and was rushed to the hospital, where Pam Gillen was being treated.

Doctors who treated both Naomi Greer Wilkinson and Pam Gillen say the severe brain injuries were the result of the traumatic effects of sudden acceleration and braking while riding the X2.

I remember one of the surgeons bursting into the emergency room and yelling, “How many have there been this month?

"They should close this attraction." He was angry.

Here's what, according to Six Flags, makes the X2 roller coaster special.

The seats rotate 360 degrees forward and backward regardless of movement along the track.

Passengers fall 200 feet at speeds of up to 76 miles per hour with two so- called “ crow turns,” or half-loops, transitioning into a steep drop.

In three lawsuits filed against Magic Mountain, passengers allege that the park intentionally concealed evidence from the public and its own visitors.

It is the design of this ride that makes it dangerous, and dangerous in a way that no sane passenger would expect.

Time and again, innocent people come out of the ride with irreversible brain damage.

Six Flags Magic Mountain announced today that X2 will be permanently closed.

The company's president wrote: " Although X2 has consistently passed numerous safety inspections, we have decided to close the attraction because we believe it is the right step." " Safety on rides is the foundation of our business, and when we see that guest trust is being undermined, we take it seriously." Pam Gillen tells us she's relieved that X2 is closing for good.

Naomi Greer Wilkinson's parents say this closure should have happened a long time ago.

Their daughter Naomi is still in the hospital in a coma.

It's time for a 10- second quiz.

When McDonald's first opened in 1948, how much did a hamburger cost?

15 cents, 50 cents, $1 or $1.10?

If you said 15 cents, then I like that.

15 cents in 1948 would be equal to about $2 today.

The average price for a regular burger at McDonald's without cheese is now $3.19.

So, it's still a significant leap compared to the " good old days." Oh, McDonald's—home of the famous Big Mac and the ever- acceptable Filet-o- Fish.

The fast- food chain recently reported that its growth slowed again last quarter.

Now they say they are investing billions of dollars in a series of profitable initiatives.

Our Stephanie Young will tell you more about what's in store for the international chain, including new healthy dishes.

Look.

McDonald's is losing ground and is going to spend $8.5 billion to get you back.

Last quarter, rival Burger King's U.S.

sales growth outpaced McDonald's by the largest margin in more than a decade.

McDonald's attributed the decline to launching too many promotions, poor customer service and a World Cup deal that failed to attract customers.

The solution is a plan called “Next”: larger dining rooms, play areas, and kitchens with AI tools to speed up work.

Then—the menu.

McDonald's claims that 60 million Americans want more protein.

So they're testing burgers and chicken bowls, egg appetizers, and grilled chicken options .

The first test will begin on October 5 , when McDonald's will begin retraining 2 workers worldwide.

All because customers are getting tired of self-service checkouts.

Fans of " Fat Bear Week," rejoice.

We have a new winner.

" Fat Bear Week 2026 " has officially ended, and a new furry king has emerged in Katmai National Park Bear 89, nicknamed "Backpack," took first place this year, and the guy has put on a lot of weight.

Over 2.5 million people voted in this year's competition, with Backpack garnering over 100,000 votes in the final round.

Rangers say this placid brown bear has been a permanent resident of Katmai since 2006, and the cute nickname "Backpack" has an even cuter story .

As a cub, he was often seen riding on the back of his mother, Holly, as they made their way up the river together.

It turns out that mom knows best.

Holly herself is a former Fat Bear Week champion.

Apparently, success or excess is inherited.

Remember, this competition is not just for fun.

It's a celebration of a thriving ecosystem.

The fatter the bear, the healthier its environment and food sources.

And although Bekpek and the other bears in the park look well-fed now, they will have lost almost a third of their weight by the time they emerge from their dens in the spring.

Congratulations to all of well-fed participants and we wish a successful hibernation to those celebrating.

Today's story gets a 10 out of 10.

Over 550 teachers from 49 states submitted applications, but only 25 received the prize.

On Tuesday, Des Moines welding teacher Chad Donaghue received some unexpected news.

It was one of the winners of the Tools for Schools Award, a competition hosted by Harbor Freight Tools.

The prize is $75,000.

Donaghue teaches welding at the Central Campus, part of the Des Moines Public School system.

He says he sees himself in each of his students.

I, uh, really care about my students.

Um, especially, uh, when they overcome difficulties, or maybe I see a little bit of myself in them.

Okay, it's almost time to say goodbye, but before that, we have time for some greetings.

This is a salute to Eastside Intermediate School in Livingston, Montana.

Thanks for subscribing to our CNN 10 YouTube channel.

Keep it up , Husky.

This next greeting is a little unusual today.

We extend a belated greeting to Mr.

Mack of Eugene A.

Ty Elementary School in Margate City, New Jersey.

Mr.

Mack left teaching to pursue his dream of becoming a firefighter, but, Mr.

Mack, your students have been writing to us this semester to make sure you get the recognition you deserve.

A hero in both chapters of your career.

This is really something worth talking about.

That's our 10 minutes for today.

I hope you have a meaningful Thursday.

See you here tomorrow.

I'm Koy Wire, and we're CNN 10.
