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.

This spring and summer may be a doozy for Lyme disease, at least in parts of the Northeast.

"We're anticipating 2017 to be a particularly risky year for Lyme," says Rick Ostfeld, a disease ecologist at the Cary Institute of Ecosystem Studies in Millbrook, New York.

Ostfeld has been studying the debilitating tick-borne disease for more than 20 years, and has developed an early warning system based on mice. For more on that, check out the piece in our sister blog, Goats and Soda.

As expected, the Zika outbreak in Florida is growing — though how fast is still difficult to say.

State and federal health officials say mosquitoes are spreading Zika in two neighborhoods of Miami, including Miami Beach. The Centers for Disease Control and Prevention told pregnant women Friday not to go into these neighborhoods — and to consider postponing travel to all parts of Miami-Dade County.

It's official. The Zika virus has established a toehold in Florida.

Fourteen people likely caught Zika in a neighborhood north of downtown Miami, health officials said Monday. That means mosquitoes in that area have picked up the virus and are spreading it.

Zika can cause severe birth defects if a woman is infected at anytime during pregnancy.

So the Centers for Disease Control and Prevention is doing something it has never done before: issuing a travel advisory to a part of the continental U.S. because of an outbreak of an infectious disease.

Editor's note, June 10: We have added an acknowledgement of several sources that Esther Gokhale used while developing her theories on back pain. These include physiotherapy methods, such as the Alexander Technique and the Feldenkrais Method, and the work of anthropologist Noelle Perez-Christiaens.

Making morphine — or heroin*, for that matter — isn't easy. You have to know a bunch of fancy chemistry to synthesize the drug from scratch. Or you have to get your hands on some opium poppies and extract morphine from the flowers' milky juice.

The latter is tougher than it sounds. Sure, the beautiful flowers grow across millions of acres around the world. But farming and trading poppies are tightly regulated both by laws and by drug kingpins.

Selling breast milk is big business.

Each year tens of thousands of women post ads on websites, offering their extra milk for $1 to $3 an ounce: "My rich milk makes giants!" promises one seller. "Organic and Gluten Free Breastmilk," claims another. Then there's this one: "470 oz. of breastmilk must go!!!"

But some women online aren't delivering what they're advertising.

Scientists at Nationwide Children's Hospital in Columbus, Ohio, analyzed 102 samples ordered from popular websites and found about 10 percent of them were "topped off" with cow's milk.

Hidden inside all of us are likely thousands of viruses — maybe more. They just hang out, harmlessly. We don't even know they're there.

But every once in a while, one of these viral inhabitants might help us out.

Young people infected with a type of herpes virus have a better immune response to the flu vaccine than those not infected, scientists at Stanford University report Wednesday. In mice, the virus directly stops influenza itself.

Malaria is one of the oldest scourges of mankind. Yet it's been a mystery how the deadliest form of the disease kills children.

One doctor in Michigan has dedicated her life to figuring that out. Now she and her team report their findings in this week's issue of the New England Journal of Medicine. The key to solving the mystery was looking inside the brain.

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:
