Michaeleen Doucleff

Michaeleen Doucleff is a reporter for NPR's Science Desk. She reports for the radio and the Web for NPR's global health and development blog, Goats and Soda. Doucleff focuses on disease outbreaks, drug development, and trends in global health.

In 2014, Doucleff was part of the team that earned a George Foster Peabody award for its coverage of the Ebola outbreak in West Africa. For the series, Doucleff reported on how the epidemic ravaged maternal health and how the virus spreads through the air. In 2015, Doucleff and Senior Producer Jane Greenhalgh reported on the extreme prejudices faced by young women in Nepal when they're menstruating. Their story was the second most popular one on the NPR website in 2015 and contributed to the NPR series on 15-year-old girls around the world, which won two Gracie Awards.

As a science journalist, Doucleff has reported on a broad range of topics, from vaccination fears and the microbiome to beer biophysics and dog psychology.

Before coming to NPR in 2012, Doucleff was an editor at the journal Cell, where she wrote about the science behind pop culture. Doucleff has a doctorate in chemistry from the University of Berkeley, California, and a master's degree in viticulture and enology from the University of California, Davis.

Last summer, Zac Peterson was on the adventure of a lifetime.

The 25-year-old teacher was helping archaeologists excavate an 800-year-old log cabin, high above the Arctic Circle on the northern coast of Alaska.

They had pitched tents right on the beach. Over the course of a month, Peterson watched a gigantic pod of beluga whales swim along the beach, came face-to-face with a hungry polar bear invading their campsite and helped dig out the skull of a rare type of polar bear.

But the most memorable thing happened right at the end of the trip.

A short drive north of Fairbanks, Alaska, there's a red shed stuck right up against a hillside. The shed looks unremarkable, except for the door. It looks like a door to a walk-in freezer, with thick insulation and a heavy latch. Whatever is behind that door needs to stay very cold.

"Are you ready to go inside?" asks Dr. Thomas Douglas, a geochemist at the U.S. Army Corps of Engineers.

Tennis superstar Serena Williams clearly has conflicted feelings about marshmallows.

In a just-published interview in Vogue magazine, she and her husband talked about the so-called "marshmallow test." It's a well-known experiment to study children's self-control first run by a Stanford psychologist in the 1960s.

ROBERT SIEGEL, HOST:

There's a race on. The way to win is to eradicate a human disease. That's only been done once before - smallpox. This year, two diseases got tantalizingly close, but unexpected roadblocks have popped up. NPR's Michaeleen Doucleff reports.

It's not every day that surgeons develop a new brain surgery that could save tens of thousands of babies, even a hundred thousand, each year. And it's definitely not every day that the surgery is developed in one of the world's poorest countries.

But that's exactly what neurosurgeons from Boston and Mbale, Uganda, report Wednesday in the New England Journal of Medicine.

We're on the Bering Land Bridge, where woolly mammoths roamed 20,000 years ago. Today, the land is covered in bright green grass and miniature shrubs.

But there's something strange — bright white objects jutting out of the ground.

As I walk a little closer with archaeologist Owen Mason, he tells me what they are.

"Right there, that's a whale shoulder blade," Mason says, pointing to a bone about the size of a German Shepherd.

The world's only vaccine against dengue has hit a roadblock, and this complication is causing some countries to restrict use of the vaccine.

Well, it looks like women have been balancing a full-time job and motherhood for thousands of years. All the while, they haven't gotten much credit for it.

By studying the bones of ancient women in Europe, archaeologists at the University of Cambridge have uncovered a hidden history of women's manual labor, from the early days of farming about 7,500 years ago up until about 2,000 years ago.

Earlier this month, the Washington Post ran a big, feature about a seemingly scary disease, called monkeypox.

"It kills up to 1 in 10 of its victims, similar to pneumonic plague, and is particularly dangerous in children," the story observes at the beginning.

Plus, the virus appears to be on rise.

In 1954, a mysterious disease struck children in Manila. They were showing up at hospitals with internal bleeding. Their blood vessels were leaking.

Over the next few years, similar outbreaks cropped up every rainy season. And then in 1958, a massive outbreak hit Bangkok. More than 2,500 children were hospitalized. About 10 percent of them died.

For decades, scientists have been making predictions about how climate change will hurt health around the world.

But actually showing a link? That's been pretty tough.

Take for example, mosquito-borne diseases. It's easy to blame rising temperatures for the global spread of Zika or the explosion of dengue fever. Mosquitoes thrive in higher temperatures, right?

Earlier this month, the toy-giant Mattel announced it had pulled the plug on plans to sell an interactive gadget for children.

The device, called Aristotle, looked similar to a baby monitor with a camera. Critics called it creepy.

Powered by artificial intelligence, Aristotle could get to know your child — at least that was how the device was being pitched.

The bond between humans and dogs isn't just psychological or the common love of bacon.

It's also genetic.

For about 15,000 years, dogs have migrated in lockstep with humans around the globe. They have followed us from Asia into Europe, North America and back to Africa — all the while hunting, protecting and snuggling us.

Now it looks as though dog DNA has evolved in lockstep with our DNA.

Scientists in China have found evidence that dogs developed protection against malaria in the same way that people in West Africa have.

Health organizations are emphasizing that myalgic encephalomyelitis/chronic fatigue syndrome is a serious long-term illness, not a psychological disorder, and that standard forms of exercise do not help. Instead, they're acknowledging that exercise can make the disease much worse unless doctors and patients are very careful.

The Centers for Disease Control and Prevention has already revised its patient guidelines on ME/CFS and is currently revising guidelines for physicians.

There's an idea percolating up from the anthropology world that may make you rethink what makes you happy.

The idea is not new. It surfaced in the popular consciousness back in the late 1960s and helped to galvanize a growing environmental movement.

And now several books are bringing it back into the limelight.
