Midway through Matt Keil's second deployment in Iraq, he came home and married his fiancee, Tracy, in 2007.

He had two weeks R&R; no time for a honeymoon.

Before he went back to war the couple had the sort of conversation unique to newlyweds in the military. "I told her if you get a phone call that I'm injured, I'm probably fine," Matt says. "But if they come to the apartment or to your work in person, then I'm dead."

U.S. manufacturers of medical devices started 2016 with a windfall — a two-year suspension of a controversial tax on their revenue.

Dr. Paul Kalanithi was preparing to wrap up his medical residency in neurosurgery when, in 2013, a CT scan revealed tumors throughout his body. He had stage 4 lung cancer.

In his last two years of life, he continued caring for patients. He and his wife became parents. And Kalanithi, a gifted writer, wrote a book, When Breath Becomes Air, a reflection on being a doctor with a terminal illness.

He died March 9, 2015. He was 37 years old.

The odds of getting Alzheimer's disease or other forms of dementia are declining for people who are more educated and avoiding heart disease, a study finds. The results suggest that people may have some control over their risk of dementia as they age.

This isn't the first study to find that the incidence of dementia is waning, but it may be the best so far. Researchers looked at 30 years of records from more than 5,000 people in the famed Framingham Heart Study, which has closely tracked the health of volunteers in Framingham, Mass.

In the summer of 2014, a 23-year-old pregnant woman entered the military hospital at Bagram Air Field in Afghanistan with a cut on her left cheek. The wound had been stitched up elsewhere, but she still wasn't quite right.

She said she'd been hit in the face by a ricochet back in her home village. What hit her exactly, she couldn't say for sure. She was upset, though, because the vision was bad in her left eye, even though there had been no apparent trauma to it.

The sighs we notice usually accompany emotions like relief or discontent. But our brains are programmed to make us heave an unconscious sigh every five minutes or so — no matter how we feel.

"Sighing is vital to maintain lung function," says Jack Feldman, a brain scientist at UCLA. These periodic deep breaths reinflate tiny air sacs in the lungs that have gone flat. But the brain circuitry behind those reflexive sighs has been a mystery.

At 46 years old, Oliver Bogler's reaction to a suspicious lump in his chest might seem typical for a man. He ignored it for three to four months, maybe longer. "I couldn't really imagine I would have this disease," Bogler says. But when he finally "grew up" and went to the doctor, he was pretty quickly diagnosed with invasive breast cancer.

Would it be ethical for scientists to try to create babies that have genetic material from three different people? An influential panel of experts has concluded the answer could be yes.

Patients suffered no additional harm when doctors training to be surgeons were allowed to work longer shifts, a study published Tuesday concludes. The findings provide fresh evidence for medical educators looking to relax the strictest limits on resident hours.

The history of science is full of happy accidents — most folks have heard that penicillin was discovered in 1928, when a few mold spores landed on some neglected petri dishes in a London lab. But sometimes serendipity's role is a bit less ... mainstream.

The World Health Organization announced Monday a public health emergency. The cause for alarm is the cluster of birth defects among babies born to mothers infected with the Zika virus, which has spread rapidly through Brazil and much of Latin America since 2015.

The World Health Organization has declared the cluster of microcephaly associated with the spread of the Zika virus to be a public health emergency of international concern — a designation reserved for an"extraordinary event" that is "serious, unusual or unexpected."

Dr. Margaret Chan, the WHO's director-general, said during a press briefing Monday that an international coordinated response was needed to improve mosquito control as well as to expedite the development of tests that detect the Zika virus.

Babies get a lot from their mothers. But babies born by cesarean section don't pass through the birth canal and miss out on the benefits from picking up Mom's microbes on the way out.

Researchers studying the human microbiome have asked: Could there be a way to fix that? If so, it might help restore the microbes a baby naturally gets that help fight off disease and foster normal development.

Any day now, Ben Lecomte will plunge into the Pacific Ocean off a Tokyo beach toward San Francisco. He wants to become the first person to swim across the Pacific. He's already the first person to free swim across the Atlantic Ocean, without a kickboard.

No one knows how the physical feat of swimming 5,500 miles will affect Lecomte's heart, but cardiologists are anxious to find out. His swim offers a rare opportunity to study whether extreme athletic performance has a harmful effect on the heart.

When Elizabeth Estes's dog, Ollie, started coughing last year, she didn't think he was seriously ill at first. But then the 3-year-old Jack Russell-chihuahua mix got much worse.

"All of a sudden, he couldn't breathe and he was coughing. It was so brutal," says Estes, who lives in Chicago. "The dog couldn't breathe. I mean, could not breathe — just kept coughing and coughing and coughing and gasping for air."

Federal health officials have this message for people who want health insurance: Don't wait.

There are just four days left to sign up for an insurance plan under the Affordable Care Act, and officials from the Department of Health and Human Services are stressing that they won't extend the enrollment period this year beyond Jan. 31.

Private health plans invoiced the state of California $387.5 million to cover high-cost hepatitis C treatments in Medi-Cal between July 2014 and November 2015, when just 3,624 patients received the treatments, according to the California Department of Health Care Services.

Just 1 percent of doctors are linked to nearly one-third of all paid malpractice claims, an analysis by researchers at Stanford finds. And the physicians who account for an outsize share of the claims have a set of distinctive characteristics.

The researchers said that the claim-prone physicians were disproportionately male (82 percent) and were older, rather than younger. More than half the claims were by doctors in four areas: internal medicine, obstetrics and gynecology, general surgery and general practice/family medicine.

The World Health Organization says it expects the Zika virus to spread to every country in the Western Hemisphere except Canada.

It says the virus has already "spread to 21 countries and territories of the Americas."

"Canada is off the list simply because it's too cold for the type of mosquito that transmits the Zika virus," NPR's Jason Beaubien reports to our Newscast unit.
