Rebecca Hersher

Rebecca Hersher is a reporter on NPR's Science Desk, where she reports on outbreaks, natural disasters, and environmental and health research. Since coming to NPR in 2011, she has covered the Ebola outbreak in West Africa, embedded with the Afghan army after the American combat mission ended, and reported on floods and hurricanes in the U.S. She's also reported on research about puppies. Before her work on the Science Desk, she was a producer for NPR's Weekend All Things Considered in Los Angeles.

Hersher was part of the NPR team that won a Peabody award for coverage of the Ebola epidemic in West Africa, and produced a story from Liberia that won an Edward R. Murrow award for use of sound. She was a finalist for the 2017 Daniel Schorr prize; a 2017 Pulitzer Center on Crisis Reporting fellow, reporting on sanitation in Haiti; and a 2015 NPR Above the Fray fellow, investigating the causes of the suicide epidemic in Greenland.

Prior to working at NPR, Hersher reported on biomedical research and pharmaceutical news for Nature Medicine.

Carmen Lugo has lived in Puerto Rico her whole life, and her whole life she has feared the water that comes out of her tap.

"When I was a child, we used filters," she says, leaning on the doorjamb with her 11-year-old in front of her and two teenage sons sleepy-eyed behind her on a morning in July.

"The water here," she says, pausing as she purses her lips in a tight smile. She chooses her words carefully. "We want to be in good health," she finally says. "My husband, he buys water from the Supermax," referring to a local grocery store.

ARI SHAPIRO, HOST:

Hurricane Florence is moving relentlessly toward the Southeastern U.S. It's a large, powerful cyclone that will likely bring storm surge and high winds to coastal communities.

But climate scientists say one of the biggest threats posed by Florence is rain.

The Houston Ship Channel has the rhythm of an ant colony. Barges and oil tankers lumber through the silty water; tangles of exposed pipe rise hundreds of feet above a sea of white tanks. Residents of the coastal plain between Houston and Galveston will tell you the plain is flatter than a regulation pool table. But if you can get up high enough you'll see trains and ships and trucks moving ceaselessly from dock to dock, terminal to terminal.
