Editor's note: There has been speculation in the media and via Twitter that DNA fragments of the now-defunct 1918 flu pathogen could be preserved under the permafrost and might pose a potential threat to humans if the warming Earth continues to melt layers of frozen soil. A couple of years ago, NPR investigated that question: Could this pathogen — and others — be revived? A version of this story originally ran in January 2018.

It's the season for colds and flus — and a newly identified respiratory disease, COVID-19.

To cut your risk of catching a respiratory illness on your next flight, experts offer two pieces of common-sense advice: Wash your hands frequently and keep a distance from people who are sick.

Where to sit to prevent getting sick

A 2018 study suggests that to minimize contact with other passengers, you should pick a window seat and stay put.

Welcome to parenthood! For many of us, parenthood is like being air-dropped into a foreign land, where protohumans rule and communication is performed through cryptic screams and colorful fluids. And to top it off, in this new world, sleep is like gold: precious and rare. (Oh, so precious.)

Throughout human history, children were typically raised in large, extended families filled with aunts, uncles, grannies, grandpas and siblings. Adding another baby to the mix didn't really make a big dent.

Imagine for a minute: A company makes a vaccine that protects kids from a life-threatening disease but, with little warning, decides to stop selling it in the U.S.

That's exactly what happened last year in West Africa, for a vaccine against rotavirus — a disease that kills about 200,000 young children and babies each year.

Six years ago, I was traveling in India, working on a story about measles. I was visiting a public hospital in New Delhi, when I walked into the waiting room and saw the tiniest baby I had ever seen.

An elderly woman — perhaps a grandma — was cradling the newborn in her arms. The little baby was wrapped in a blanket, and a tiny knit cap covered her head, which wasn't much bigger than a small orange. The newborn could not have weighed more than four pounds.

The U.S. Food and Drug Administration just approved one of the most sought after vaccines in recent decades. It's the world's first vaccine to prevent dengue fever — a disease so painful that its nickname is "breakbone fever."

The vaccine, called Dengvaxia, is aimed at helping children in Puerto Rico and other U.S. territories where dengue is a problem.

Is it possible to raise children without shouting, scolding — or even talking to kids with an angry tone?

Last month, we wrote about supermoms up in the Arctic who pulled off this daunting task with ease. They use a powerful suite of tools, which includes storytelling, playful dramas and many questions.

Measles is surging. Last week the U.S. recorded 90 cases, making this year's outbreak the second largest in more than two decades.

So far this year, the U.S. has confirmed 555 measles cases, the Centers for Disease Control and Prevention announced Monday. That's 50 percent higher than the total number recorded last year, even though we're only about a quarter of the way through 2019.

And the virus isn't slowing down.

Six months ago, I found myself preparing for battle.

I was lying in bed at 5:30 a.m., going over in my head how to handle the next encounter with my 3-year-old daughter, Rosy.

Goodness knows, I love her so much. But there's a fire in that little belly. And to be honest, I have no idea how to handle all the anger — the tantrums, the screaming and, most of all, the hitting.

When she's angry and I pick her up, she has a habit of slapping me across the face. Sometimes it really hurts. I've even started ducking like a boxer when I lift her up.
