In the wake of the pandemic, many people are struggling with their mental health regardless of their age.

But recently published data from the CDC is shedding light on how teens are faring.

The numbers show that 4 in 10 U.S. high schoolers experienced persistent feelings of sadness or hopelessness in 2021. Nearly a quarter seriously considered attempting suicide.

We discuss how parents can help teens navigate this tumultuous period.

Hospice care in the United States began as a social movement in the 1960s and '70s.

What was once provided mainly by nonprofits, is now a $22.4 billion industry. Now, more than 70 percent of hospice clinics are for-profit businesses.

And the rate of Americans choosing hospice is only going up. More than half of Americans will spend their final days in hospice.

We check in on the hospice care industry — what it is, how it works, and what you need to know to prepare end-of-life services.

Cities across the country are using green space to combat the effects of climate change. Many are going beyond tree planting by rezoning abandoned infrastructure — like railroads and suspended highways — to create expansive, vibrant urban parks.

But new data shows that this environmental revitalization is driving gentrification and displacing people in low-income communities.

How can cities balance the impact of green gentrification with the need to adopt more climate-resilient developments?

President Joe Biden was in Europe this week, prompting commentary from his critics. Arizona Rep. Andy Biggs says he wants future funding to Ukraine pulled and disagrees that it's America's job to defend the country's sovereign borders.

While in Europe, President Biden crossed into Kyiv by train on Monday, aboard what's been dubbed "Rail Force One." The surprise trip lasted less than a day. But it sent a big message. It's the first time the president has visited Ukraine since Russia's full-scale invasion of the country a year ago.

At least 11 Palestinians were killed Wednesday in a raid by Israeli military forces in the occupied West Bank. More than 100 people were injured.

And Nigerians head to the polls. More than 90 million voters will have a say in who next leads Africa's most populous country. President Muhammadu Buhari is term-limited. There are 18 people on the ballot to replace him.

We cover all this and more during the News Roundup.

What do you do when a train carrying toxic chemicals crashes in your town?

East Palestine, Ohio, is finding out the hard way.

A train derailed earlier this month, but the mess still hasn't been cleaned up. Now officials are playing the blame game, with East Palestine residents stuck in the middle.

Trains roll through America's small towns every day. So who's responsible when things go so wrong?

We discuss what's next for East Palestine residents.

Today, artificial intelligence is being used by law enforcement for facial recognition and even predictive policing. It can help solve and prevent crimes, but it's not foolproof. That's resulted in wrongful arrests and continued racial profiling in policing.

Outside the U.S., so-called "safe cities" use AI and big data for "Big Brother" surveillance systems.

We ask how much these technologies can curb crime, and at what cost to our freedom.

AI is being used for all kinds of tasks in health care — whether it's administrative ones like taking notes, parsing through patient data, or providing some extra help with reading images.

Some AI platforms like Bayesian Health are helping filter through loads of data that get put into a health system.

And some clinicians are testing out what AI can and can't do quite yet, like a team at Emory University who found out an AI system could detect a patient's self-reported race based on a chest scan.

For this episode of "Know It All: 1A and WIRED's Guide to A.I.", we're exploring what AI in health care looks like today and its potential.

ChatGPT is incredibly popular online, boasting more than 100 million monthly active users within just two months of its launch last November.

The program is powered by a language model that is programmed to produce human dialogue. Users can feed it a prompt, and ChatGPT will predict how it should respond.

This makes teachers nervous. Educators are concerned the application will fundamentally change how writing is taught and will impact students' abilities to craft ideas on their own.

Meanwhile, other teachers are getting creative with the technology.

We assemble a panel of guests to discuss the impact of artificial intelligence on our schools. It's part of our series Know It All: 1A and WIRED's Guide to AI.

On Thursday, President Joe Biden broke his silence on the recent downings of UFOs in U.S. airspace. He said U.S. intelligence has no indication that three objects shot down in recent days were surveillance craft from China.

Earlier this month, a train carrying hazardous chemicals derailed in East Palestine, Ohio, releasing toxic materials into the town. Last week, some of the chemicals were burned in what officials called a "controlled explosion."

Meanwhile, it's been 10 days since twin earthquakes and several aftershocks hit Syria and Turkey. Recovery and aid groups are still working around the clock to get immediate supplies, medicine, and shelter to survivors.

And as the one-year anniversary of Russia's full-scale invasion of Ukraine approaches, the U.S. is expecting Ukraine to launch a spring offensive. Russia has been stepping up its offensive in eastern Ukraine – battling, unsuccessfully, for the city of Vuhledar.

We discuss all this and more during the News Roundup.
