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.

The Arkansas River just keeps rising. The usually placid tributary of the Mississippi has become a bloated torrent carrying entire trees downstream, drowning riverfront property and halting commerce for hundreds of miles.

Federal weather forecasters are predicting a "near normal" number of storms this hurricane season, which runs from June 1 through November 1.

Between nine and 15 named storms, including includes tropical storms, are predicted to form in the Atlantic this year, said Neil Jacobs, acting administrator of the National Oceanic and Atmospheric Administration.

The Mississippi River is rising again as torrential rain falls across much of the Midwest. It's the latest in a series of storms that have flooded major cities and small communities along the length of the Mississippi and Missouri rivers on and off for more than a month.

Scientists are ramping up research on the possible health effects of a large group of common but little-understood chemicals used in water-resistant clothing, stain-resistant furniture, nonstick cookware and many other consumer products.

Detecting very small earthquakes is notoriously difficult. The churning of the ocean, a passing car or even the wind can feel a lot like a minor quake to the sensors that blanket seismically active parts of the U.S.

That's a problem for scientists who rely on data about all the earthquakes in a region to study what triggers the biggest, most destructive ones.

Hurricane Maria was the rainiest storm known to have hit Puerto Rico, and climate change is partly to blame, according to a new study.

The worst rain fell in the mountainous central part of Puerto Rico, from the northwest to the southeast. That part of the island is rainy under normal conditions. In an average year, it gets more than 150 inches of rain.

When Maria hit in 2017, it dropped nearly a quarter of that annual rainfall in just one day.

An hour south of Charlotte, N.C., two forks in the road beyond suburbia, a freshly constructed house sits in a wind tunnel waiting to be set on fire.

To the left of the house is a brick wall with a hole in the middle, made by a 2-by-4 propelled at 70 miles per hour.

In front of the house is a metal staircase five stories tall. At the top are the hail guns.

More than 100 fans begin to turn, slowly at first and then faster. The ember generators flicker on. The fire is about to begin.

Several members of a powerful science panel for the Environmental Protection Agency expressed doubt at a hearing Thursday about the long-established scientific consensus that air pollution can cause premature death.

The panel was meeting to consider recommendations that would fundamentally change how the agency analyzes the public health dangers posed by air pollution and could lead to weaker regulation of soot.

When a storm gets very intense very quickly, it gets a very special, very scary name: bomb cyclone.

And just such a storm has arrived in the central U.S.

If they had known, they never would have bought the house on Bayou Glen Road. Sure, it was a beautiful lot, tucked in a bend of the creek, backyard woodsy and wild, the neighbors friendly and the street quiet. A little piece of nature just 20 minutes from downtown Houston. It was exactly what John and Heather Papadopoulos — recently married, hoping to start a family — were looking for in 2007. They didn't think much about the creek that ran along their yard, aside from appreciating the birds it attracted to the neighborhood.
