The National Security Agency is scaling back the way it spies on some communications over the Internet.

The NSA says it discovered what it called "lapses" in compliance with U.S. law.

They're called "about" communications: The NSA not only watches messages traveling to and from a foreign target, but those that mention one.

That can mean the NSA sometimes sweeps up data from Americans without a warrant. In the past, officials said the spy agency was still mindful of citizens' privacy.

The Circle, the film based on the novel by Dave Eggers, presents a dystopian view of the direction Silicon Valley is taking the world. And, as a longtime Silicon Valley correspondent, I have to say there is a lot that this comic and spooky film gets right.

Accessing the Internet in Cuba isn't easy. Home Internet connections are rare, and public access Wi-Fi hotspots costs $1.50 an hour — very expensive for most Cubans.

But in the nation that has been called "one of the most restrictive media environments in the world," watching YouTube got faster this week.

New York City is set to begin giving body cameras to its police officers on Thursday.

Under the police department's pilot program, 1,200 officers in 20 precincts will receive the cameras. The officers will also be studied by scientists to see what effect the cameras have on policing.

As police don body cameras across the country, scientists are increasingly working with departments to figure out how the cameras change behavior — of officers and the public.

If you're one of the many who text, read email or view Facebook on your phone while driving, be warned: Police in your community may soon have a tool for catching you red-handed.

The new "textalyzer" technology is modeled after the Breathalyzer, and would determine if you had been using your phone illegally on the road.

A careful study of President Trump's tweets reveals something about the man who's writing them. NPR's Danielle Kurtzleben has been running the president's words through computer analysis and has learned something about how he might be feeling this very week. Hi, Danielle.

Net neutrality regulations are getting yet another remake.

The new head of the Federal Communications Commission on Wednesday launched his long-expected campaign to undo the regulations adopted in 2015 under former President Barack Obama. Specifically, FCC Chairman Ajit Pai wants to loosen the legal structure that placed Internet service providers under the strictest-ever oversight of the agency, in favor of a "light-touch regulator framework."

The annual TED conference is known for featuring impressive speakers. Attendees at this year's event in Vancouver have seen Serena Williams and Jorge Ramos, futurists and artificial intelligence experts, health activists and the ACLU's executive director.

But on Tuesday evening, one unannounced speaker took the audience by surprise: Pope Francis.

The pope was on a big screen rather than onstage, and his address had been recorded and edited earlier in April, but still: even for non-Catholics, the bishop of Rome has a certain gravitas.

Appliance manufacturers and home builders are in Washington, D.C., today to celebrate a popular energy efficiency program, even as it's slated for elimination in President Trump's proposed budget.

You probably know the program's little blue label with the star — the Environmental Protection Agency says 90 percent of U.S. households do.

President Trump may not talk much about electric vehicles, but there's another American — with better name recognition in China — who does.

The voice of actor Leonardo DiCaprio, popular in China for his role in the 1997 blockbuster Titanic, graces the showroom of Auto Shanghai, the city's biennial automotive expo, accompanied by images beamed on a circular wall showing Beijing covered in smog and children wearing pollution masks.

After high school, Staff Sgt. Kimi wanted to go to art school, but she didn't have the money. So she joined the military.

Intelligence analysts like Kimi work with drone pilots and others in the Air Force to guide decisions about where to deploy weapons in the fight against ISIS and al-Qaida. (The U.S. Air Force won't release her last name because of the high-security work she does).

Video of a murder uploaded to Facebook this week upset many users, especially since it took Facebook two hours to take it down. But the incident illustrates a dilemma for the company as it becomes an open platform for both recorded and livestreamed video.

Facebook CEO Mark Zuckerberg was contrite about the incident when he appeared on stage at the company's F8 developer's conference.

Sometimes, it's the Internet of stings.

Juicero, a startup that sells a pricey juice press, found that out firsthand. The company's Wi-Fi-enabled machine produces cold-pressed juice out of packets sold exclusively to owners via subscription.

About Jeremy Howard

People love seeing black bears when they visit Yosemite National Park in California. But encounters don't always go well. The park has come up with a new way to keep humans and bears safe.

Fresno State University student Quiang Chang was walking recently with his friends along the rushing Merced River. It was his fifth time visiting Yosemite National Park, and he hadn't seen a bear.

But if they appear, Chang said, "I probably would just quietly ... just observe them and take a picture."
