Nationwide, people who vape continue to sicken with severe and unexplained lung illness, leaving doctors and patients concerned about both the acute and long-term effects of the injuries.

The Centers for Disease Control and Prevention announced Thursday that there are now 530 confirmed or probable cases of lung injury associated with vaping, a jump from 380 cases reported last week. Seven people have died.

A 14-year-old boy goes to the doctor with complaints of tiredness. He's an extremely picky eater. (Think a daily diet of French fries, plus snacking on Pringles potato chips, white bread and some processed pork.) But overall, he appears OK. He's not overweight and takes no medications.

Tests show he has anemia and low levels of vitamin B12, so he's given B12 injections and diet advice. But a year later, he has begun to lose his vision. Then, by age 17, he's legally blind.

The shooter who opened fire after a routine traffic stop Saturday in Texas, killing seven people and injuring 22, was fired just hours before the deadly shooting.

Seth Aaron Ator, 36, who lived in the Odessa area, had been fired from his job at Journey Oilfield Services after a disagreement, according to Odessa Police Chief Michael Gerke. The shooting rampage, which appears to have been random, ended when Ator was killed by police.

At a time when more than 30 states and the District of Columbia have legalized the use of marijuana for either medical or recreational use, the U.S. surgeon general says no amount of the drug is safe for teens, young adults and pregnant women.

Packing a turkey sandwich in your kid's lunchbox, or serving up bacon or hot dogs?

When shopping for processed meats, many health-conscious consumers look for products with words like "no nitrates added" or "uncured" on the packaging. But we may have been misled, experts say.

A new report finds that deli meats with those labels actually contain similar levels of nitrates as meats that don't carry these labels.

Virtual reality is not new. But, as people search for alternative ways to manage pain — and reduce reliance on pills — VR is attracting renewed attention.

Imagine, for a moment you've been transported to a sunlit lagoon. And, suddenly, it's as if you're immersed in the warm water and swimming. That's what Tom Norris experiences when he straps on his VR headset.

Emphysema is considered a smoker's disease. But it turns out, exposure to air pollution may lead to the same changes in the lung that give rise to emphysema.

Could it happen here? It's a question a lot of people ask in the wake of a traumatic event.

Even if you're not directly connected to the events in El Paso, Gilroy or Dayton, chances are you've felt the weight of them.

Humans must drastically alter food production to prevent the most catastrophic effects of global warming, according to a new report from the United Nations panel on climate change.

The panel of scientists looked at the climate change effects of agriculture, deforestation and other land use, such as harvesting peat and managing grasslands and wetlands. Together, those activities generate about a third of human greenhouse gas emissions, including more than 40% of methane.

Allergan has announced a global recall of textured breast implants that are linked to a rare type of cancer, at the request of the Food and Drug Administration.

"Biocell saline-filled and silicone-filled textured breast implants and tissue expanders will no longer be distributed or sold in any market where they are currently available," according to a company statement Wednesday.

If everyone around the globe began to eat the recommended amounts of fruits and vegetables, there wouldn't be enough to go around. That's the conclusion of a new study published in The Lancet Planetary Health.

Sun exposure is the leading risk factor for developing melanoma. And there's evidence that alcohol consumption is linked to an increased risk of skin cancer, too.

Part of the explanation is that when people drink, they tend to be more lackadaisical: They're less likely to apply sunscreen and more likely to spend too much time in the sun, be it at the beach or pool. But this isn't the whole story.

When Athletic Brewing Co. offered its nonalcoholic limited-edition Double Hop IPA for sale online last week, it sold out in 32 seconds.

"We've actually been totally overwhelmed and shocked by how strong the nationwide online demand is," says Bill Shufelt, co-founder of Athletic Brewing Co., which produces only nonalcoholic brews.

A new study published in The BMJ can't tell you exactly how much red meat is OK to eat to maintain good health or prevent disease.

But it does help sort out a big-picture, and perhaps more important, question: What does a healthy pattern of eating look like?

The U.S. Preventive Services Task Force has a new recommendation aimed at preventing HIV infections and AIDS. The influential panel's guidance says people at high risk of being infected with HIV should be offered preventive antiretroviral medications — taken in a daily pill.

There's lots of evidence that preexposure prophylaxis — also known as PrEP — is effective. The Food and Drug Administration-approved pill Truvada contains two antiretroviral medicines (tenofovir and emtricitabine).

For roughly 40 million Americans, SNAP benefits are a lifeline.

The Supplemental Nutrition Assistance Program, formerly known as food stamps, delivers about $60 billion in aid each year. And retailers that accept SNAP benefits are required to stock a variety of staple foods — including a minimum number of fruits and vegetables, meat, dairy and grain options.

The Food and Drug Administration is holding its first public hearing on CBD, the cannabis extract that has quickly grown into a billion-dollar industry. Today's hearing will help officials determine how to regulate CBD products.

The compound can be extracted from marijuana or from hemp. It's promoted as a way to ease anxiety and inflammation – and it doesn't get people high because it doesn't contain THC, the psychoactive component of the cannabis plant.

There's nothing magical about the number 10,000.

In fact, the idea of walking at least 10,000 steps a day for health goes back decades to a marketing campaign launched in Japan to promote a pedometer. And, in subsequent years, it was adopted in the U.S. as a goal to promote good health. It's often the default setting on fitness trackers, but what's it really based on?

"The original basis of the number was not scientifically determined," says researcher I-Min Lee of Brigham and Women's Hospital.

The Food and Drug Administration sent a letter to the food industry on Thursday, urging companies to get behind the initiative to standardize the use of the phrase "best if used by" on packaged food labels.

"A Low-Fat Diet Helps Reduce The Risk of Death From Breast Cancer." Did a headline like this catch your eye this week?

Dozens of news organizations, including NPR, reported on a new study that found that a low-fat diet helped women reduce their risk of dying from breast cancer.

Almost everyone gossips.

And a new study finds that people spend about 52 minutes per day, on average, talking to someone about someone else who is not present.

But here's the surprise: Despite the assumption that most gossip is trash talk, the study finds that the vast majority of gossip is nonjudgmental chitchat.

Feel like you're living under a rain cloud? Life not going your way? Lots of us have a bit of Eeyore's angst and gloom.

But here's the good news (sorry to be so cheery): You can be taught to have a more positive attitude. And — if you work at it — a positive outlook can lead to less anxiety and depression.

Measles is on the rise again, all around the globe.

Though the number of people affected in the U.S. is still relatively low compared with the countries hardest hit, there are a record number of U.S. measles cases — more than 700, so far, in 2019, according to the CDC — the highest since the disease was eliminated in the U.S. back in 2000.

An estimated 40% of adults in the U.S. snore. And, men, you tend to out-snore women. (Yes, this may explain why you get kicked or shoved at night!)

And despite the myth that snoring is a sign of deep sleep, there's really no upside to it.
