A gunman in Virginia murdered two television journalists, Alison Parker and Adam Ward, as they conducted a live on-air interview on Wednesday. The suspect, Vester Lee Flanagan, apparently had a camera.

Flanagan didn't just want to shoot the victims. He wanted to film himself in the act of committing murder.

Here's an awkward situation. You're in Hawaii with your spouse, vacationing. And you find out you've been exposed as part of an adultery website. Your email is in the Ashley Madison data that hackers leaked. This is precisely the situation in which Casey Corcoran found himself.

An Awkward Moment

Over the weekend, Corcoran and his wife were in a hotel room overlooking the ocean. It was about 6:30 p.m.

If you've ever had surgery, you may have been given an analgesic named fentanyl.

Fentanyl is a favored painkiller because it acts fast. But it's also 80 to 100 times more potent than morphine. The powerful drug has made its way to the streets and increasingly is being used to cut heroin — resulting in a deadly combination.

Angelo Alonzo, a resident of Portland, Maine, says he nearly died last month after injecting what he believed to be a safe dose of heroin — the same amount he's taken before. But this time, he says, the drug knocked him to his knees.

"An amount that usually gives me a good mellow high was just way too much," he says, "and I woke up in the shower and I was cold. And I didn't put myself there."

People whose diabetes requires insulin injections usually have to make a series of visits to the doctor's office to fine-tune their daily dosage. But many low-income patients can't afford to take those few hours off to see the doctor. As a result, they often live with chronically elevated blood sugars for weeks or months until they can find time to get to the clinic.

Nearly one month after its release, the Windows 10 operating system has been installed on more than 75 million devices, according to Microsoft. That figure reflects worldwide adoptions of the OS that, for now at least, is a free upgrade. Windows 10 is Microsoft's most substantial update since 2012.

Microsoft Vice President Yusuf Mehdi announced Tuesday that the new operating system is running in 192 countries, and on a wide range of devices, including ones made as early as 2007.

Peek into a Peloton indoor cycling class in New York's posh Chelsea neighborhood and it'll look like most other indoor cycling classes. Sixty stationary bikes are clustered in a dark room, loud music blares to get the heart racing, and a mic-ed up instructor motivates riders.

Except this class has one major difference: Instructor Jen Sherman isn't just talking to riders in the classroom. She's also monitoring metrics for riders in places like New Jersey, California, Massachusetts and Kansas. "Jamie in Wichita, good to see you this morning," she says.

I stepped out my parents' front door last Thursday, expecting a typically glorious summer day in southern Oregon. Instead, I was hit with acrid wood smoke that stung my eyes and throat. The air was thick with haze that obscured the mountains. I quickly retreated inside.

Health departments across the West are mobilizing to protect residents from smoke generated by dozens of fires that have sent smoke as far east as the Midwest.

There's a new candidate in the century-old quest for perfect, guiltless sweetness.

I encountered it at the annual meeting of the Institute of Food Technologists, a combination of Super Bowl, Mecca, and Disneyland for the folks who put the processing in processed food.

Doctors' practices are increasingly trying to reach their patients online. But don't expect your doctor to "friend" you on Facebook – at least, not just yet.
