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 Environmental Protection Agency has removed a toxic waste site flooded by Hurricane Harvey from a special list of contaminated sites that require the personal attention of the agency's leader, because it says there's been significant progress on a cleanup plan.

MARY LOUISE KELLY, HOST:

The head of the Environmental Protection Agency is fending off multiple accusations that he misused taxpayer funds and maintained improper ties to companies regulated by the EPA.

President Trump's nominee for deputy administrator of the Environmental Protection Agency, Andrew Wheeler, has spent much of his career working for less oversight from the agency.

MICHEL MARTIN, HOST:

An analysis published Friday confirms the state of American gun policy science is not good, overall.

The nonprofit RAND Corporation analyzed thousands of studies and found only 63 that establish a causal relationship between specific gun policies and outcomes such as reductions in homicide and suicide, leaving lawmakers without clear facts about one of the most divisive issues in American politics.

In 2015, the top toxicologist for the state of Texas, Michael Honeycutt, was interviewed on Houston Public Radio. At the time, the Environmental Protection Agency was pushing for tighter limits on ozone, a type of air pollution that is hazardous for people with asthma and other respiratory diseases.

In 2016, EPA Administrator Scott Pruitt told a radio host in Tulsa, Okla., "I believe that Donald Trump in the White House would be more abusive to the Constitution than Barack Obama, and that's saying a lot."

His comments surfaced at a routine Senate committee hearing on Tuesday, when Sen. Sheldon Whitehouse, D-R.I., read from a transcript of the interview and asked administrator Pruitt whether he remembered it. "I don't, Senator," Pruitt replied, "and I don't echo that today at all."

A new study describes, in detail, the stiffness of beetle penises, which might serve as inspiration for people who design medical catheters.

The industry has long struggled with an engineering problem: How do you keep a very thin tube flexible enough to snake into hard-to-reach places but rigid enough to withstand insertion? Plus, there is the problem of buckling — when a thin tube crimps so fluids can't flow through it anymore.

Ticks sucked the blood of feathered dinosaurs some 99 million years ago, a new study suggests.

Modern ticks are infamous for biting humans and other mammals. But ticks are very ancient, and scientists who study their evolution have long wondered what (or who) the little vampires ate before there were lots of mammals to feed on. Feathered dinosaurs apparently were among the possible creatures on the menu.
