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.

Scientists have started to unravel a key mystery about the Zika virus. And the findings are almost unbelievable.

"When I first started reading the study, I said, 'Oh, my gosh, that's amazing,' says molecular biologist Alysson Muotri, at the University of California, San Diego, who wasn't involved in the study.

The study — published Thursday in the journal Science — demonstrates how an obscure virus may have transformed into a global threat almost overnight.

Zika may have fallen from headlines, especially with everything going on in politics these days, but the threat remains.

And recommendations for pregnant women haven't changed: Pregnant women — and those trying to get pregnant — should not travel to places where the Zika virus is circulating.

It's just too risky because Zika can cause birth defects.

But what about babies? Or kids? Is it safe to travel with them?

This year we've learned an amazing amount about Zika — how it damages developing brains, how it spreads through sexual contact and where in the world (and the U.S.) it's hiding out.

It's one of the biggest medical mysteries of our time: How did HIV come to the U.S.?

By genetically sequencing samples from people infected early on, scientists say they have figured out when and where the virus that took hold here first arrived. In the process, they have exonerated the man accused of triggering the epidemic in North America.

It began with anxiety and depression. A few months later, hallucinations appeared.

Then the Texas man, in his 40s, couldn't feel the left side of his face.

He thought the symptoms were because of a recent car accident. But the psychiatric problems got worse. And some doctors thought the man might have bipolar disorder.

Eventually, he couldn't walk or speak. He was hospitalized. And about 18 months after symptoms began, the man died.
