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 not every day that the world gets a new tool that could save 100,000 children each year.

And it's definitely not every day that the secret to that tool is the same thing that makes space ice cream so memorable.

Sounds crazy. But bear with me a moment.

Scientists say they have a new vaccine that's about 70 percent effective against rotavirus — a nasty little pathogen that gives children bad diarrhea here in the U.S. but kills more than 200,000 children each year in developing countries.

A few years ago, Dr. Gregory Thomas thought he had finally found the Holy Grail of heart disease. And it was even found in a tomb.

He was studying the arteries of 3,000-year-old Egyptian mummies, and he thought this was finally it: a culture that would be free of heart disease. Heart disease couldn't be more than 3,000 years old, could it?

Man, he was disappointed.

No matter how you slice it, outbreaks are becoming more common. Overseas, there's been Ebola, Zika and yellow fever. And here at home, we're seeing a surge in tick-borne diseases, with Lyme leading the way.

For the past month, NPR has been looking at why this is the case. Deforestation lets animal viruses jump into people. Factory farming amplifies the problem. And then international tourism spreads the new diseases around the globe.

But throughout our series, there's been something else on people's minds.

Last summer Felicia Keesing returned from a long trip and found that her home in upstate New York had been subjected to an invasion.

"There was evidence of mice everywhere. They had completely taken over," says Keesing, an ecologist at Bard College.

It was a plague of mice. And it had landed right in Keesing's kitchen.

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.

It was a balmy Sunday evening in early 1999, and Dr. Kaw Bing Chua hadn't had lunch or dinner.

There wasn't time to eat. Chua was chasing a killer. And he thought maybe he had finally tracked it down.

He slid the slide under the microscope lens, turned on the scope's light and looked inside. "A chill went down my spine," Chua says. "The slide lit up bright green, like bright green lanterns."

Welcome to the bat cave. No, we're not talking about the secret headquarters of a superhero.

This is Gomantong — an ancient cave carved out of 20 million-year-old limestone in the middle of the Borneo rain forest in Malaysia. It's part of a vast network of tunnels and caverns. And it's the perfect hideout for bats.

Up at the top are millions of bats. Literally millions. They hang upside down all day long from the cave's ceiling, sleeping and pooping.

Pygmy elephants. Monkeys with noses the size of beer cans. And a deer so small you could cradle it like a baby.

And right there, sitting on a leaf, is the strangest bug we've ever seen.

"Check out the size of it," says virus hunter Kevin Olival as he picks up a ginormous roly-poly. "It's the size of a ping-pong ball!"

If you're a germaphobe, make sure you're sitting down.

Back in 1999, a woman in California cleaned up rodent droppings in her home. Two weeks later, her liver started failing. Then she started to bleed internally — a hemorrhagic fever that would kill her. Eventually doctors found a new virus in her body, which very likely came from a rat.

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.

When Ebola struck West Africa a few years ago, the world was defenseless. There was no cure. No vaccine. And the result was catastrophic: More than 11,000 people died. Nearly 30,000 were infected.

Now it looks like such a large outbreak is unlikely to ever happen again. Ever.

The world now has a potent weapon against Ebola: a vaccine that brings outbreaks to a screeching halt, scientists report Thursday in The Lancet.

Bacteria are way smarter than we give them credit for.

No, I'm not talking about "brain smarts." Bacteria don't have neurons.

I'm referring to "chemical smarts": the ability to make, break down or gobble up whatever compound they want. Even if they've never been exposed to it before.

Scientists have found a superbug — hidden 1,000 feet underground in a cave — which is resistant to 70 percent of antibiotics and can totally inactivate many of them.

Frequent removal of pubic hair is associated with an increased risk for herpes, syphilis and human papillomavirus, doctors at the University of California, San Francisco, reported Monday in the journal Sexually Transmitted Infections.

The World Health Organization announced Friday that it no longer considers the Zika epidemic a public health emergency of international concern.

But Zika's threat to pregnant women and babies is not going away anytime soon, the agency says. Instead, the virus is now a chronic problem, says the WHO's Dr. Pete Salama.

Optimism. That's what we could all use right now.

So here at Goats and Soda, we're going to give you a whole heaping tablespoon of it. And we'll do it by answering a question from a reader named Ian Matthews that seems to bring the opposite reaction: "How can we stop the spread of antimicrobial resistance?"

As it turns out, the answer has a surprisingly positive message.

People and leprosy go way back. Way, way back.

"It's been around for at least 5,000 years and probably longer," says Stewart Cole, who directs the Global Health Institute at the Swiss Federal Institute of Technology.

One mutation. A simple tweak in the Ebola gene — a C got turned into a T. That's all it took to make Ebola more infectious during the West Africa epidemic, scientists report Thursday.

Two studies, published in the journal Cell, found that a single mutation arose early in the epidemic. It allows Ebola to infect human cells more easily than the original version of the virus — way more easily.

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.

There's a heated debate in the Arctic Circle. It's about reindeer. Lots of them.

Russian health officials want to cull a quarter million animals by Christmas, The Siberian Times reports. That's enough reindeer to fill about 400 Olympic-sized swimming pools.

Historical. A possible turning point.

These are the words health researchers are using to describe a declaration passed Wednesday by the U.N. General Assembly aiming to slow down the spread of superbugs — bacteria that have become resistant to antibiotics.

"I think the declaration will have very strong implications," says the World Health Organization's Dr. Keiji Fukuda. "What it will convey is that there's recognition that we have a big problem and there's a commitment to do something about it."

From anthrax outbreaks in thawing permafrost to rice farms flooded with salty water, climate change seems to play a bigger and bigger role in global health each year.

Vampire bats are thirsty creatures. And they drink only one beverage: mammalian blood.

Each night, they hop on the ground, crawl up to an unsuspecting victim and latch onto its ankle.

Then the little critters use razor-sharp incisors to slice a deep, tiny wound into a victim's skin. As blood flows out of the wound, the bat laps it up — about a tablespoon per bite.

Most of the time, these bites are harmless – if not a bit uncomfortable. But if the bat carries rabies, a quick nip can be deadly.

A ticking time bomb. That's what some health officials say the Zika virus is in Southeast Asia.

Special K. K-land. Or even "baby food," because users sink into "a blissful, infantile inertia," the Drug Enforcement Agency says — ketamine is best known as a club drug here in the U.S.

Most recently, ketamine played an integral role in HBO's summer murder mystery The Night Of — Andrea and Naz took some and hooked up. He blacked out and awoke to find her stabbed to death in her bed. And he doesn't remember whether he did it.
