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.

It's March. It's freezing. And there's half a foot of snow on the ground. When is this winter going to end?

For centuries, arsenic was the go-to poison for murder.

If you wanted to knock off an heir to the throne or speed up the arrival of your inheritance, all you had to do was add a dollop of rat poison to your rival's food. They wouldn't see or taste it. And the police wouldn't detect it — at least not until a chemist developed a test for the element in the early 19th century.

The Ebola epidemic has taken a heartbreaking toll on children.

More than 1,000 children have died from the disease. Even more have lost parents, grandparents and siblings.

Speed. That's key to ending the Ebola epidemic, health officials have been saying for months. Now there's a new tool to help do the trick.

The World Health Organization approved the first quick test for Ebola Friday. The test gives results in about 15 minutes, instead of hours. So people infected can get treatment and be quarantined more quickly.

"It's definitely a breakthrough," WHO spokesman Tarik Jasarevic said Friday in Geneva.

With all his homemade gadgets and cool scientific tricks, MacGyver is an engineering superhero.

A few months ago, I met a grandpa whom I'll never forget.

His name is Edwin Koryan. And he's a pharmacist in Voinjama, Liberia. Edwin remembers the moment he felt the first symptoms of Ebola. He was taking care of his 5-year-old granddaughter Komasa. They were sharing a room and a bed.

In 1962, children's book author Roald Dahl lost his oldest daughter, Olivia, to measles. She was 7 years old.

Twenty-six years later, Dahl wrote a letter to parents about what happened:

World maps distort — it's inherent in their design.

Take a spherical object (the Earth) and try to represent it on a flat plane (paper), and some parts of the sphere are going to get stretched. On most maps, Canada and Russia get puffed up, while countries along the equator get shrunk.

Every now and then, though, you stumble across a map that enlightens.

Delhi belly. That's what my brother-in-law calls the rumble in his stomach he invariably gets on business trips to India.

Like many travelers, he pops a few Cipro when Dehli belly hits. That may stop the microbes causing the GI distress, but it also opens the door to another unwanted visitor: drug-resisted bacteria.

Back in July, NPR launched a new blog. It had a funny name, but a clear objective: To tell memorable stories about people who don't get much attention, who may face big problems, from health to poverty, but who still thrive.

A few years ago, disease ecologist David Hayman made the discovery of a lifetime.

He was a graduate student at the University of Cambridge. But he spent a lot of that time hiking through the rain forest of Ghana, catching hundreds of fruit bats.

"We would set large nets, up in the tree canopies," he says. "And then early morning, when the bats are looking for fruit to feed on, we'd captured them."

Hayman didn't want to hurt the bats. He just wanted a few drops of their blood.

Most of us will remember 2014 as the year Ebola came to the U.S. But another virus made its debut in the Western Hemisphere. And unlike Ebola, it's not leaving anytime soon.

The virus is called chikungunya: You pronounce it a bit like "chicken-goon-ya."

Dengue — aka "breakbone fever" — has been a tough nut to crack when it comes to making a vaccine.

The problem is that the mosquito-borne virus comes in four flavors, or strains. Vaccines that work on one strain haven't worked well on the others.

Now scientists at Imperial College London have discovered a potential way around this problem.

Immunologist Gavin Screaton and his colleagues have found molecules — specifically antibodies — in human blood that stop all forms of dengue.

Speed. That's key to ending the Ebola epidemic, says the director of the U.S. Centers for Disease Control and Prevention.

Dr. Thomas Frieden is visiting West Africa this week to figure out how to reduce the time it takes to find new Ebola cases and isolate them.

Otherwise, Ebola could become a permanent disease in West Africa.
