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.

Paleontologists at the University of New South Wales in Australia say they have identified a tiny new species of marsupial lion that lived around 18 million years ago.

The extinct, squirrel-size animal weighed about 1.3 pounds, very likely lived in trees and had teeth that suggest it was capable of ripping apart other small creatures with its molars.

The researchers named it Microleo attenboroughi in honor of Sir David Attenborough, the famed British naturalist who has hosted numerous documentaries on wildlife.

More than a week after record-breaking rain inundated 20 parishes in southeastern Louisiana, President Obama arrived Tuesday to survey the damage.

The president toured a neighborhood in East Baton Rouge Parish ravaged in the widespread flooding that has claimed more than a dozen lives and damaged some 60,000 homes. Afterward, he thanked first responders, the National Guard and "all the good neighbors" who rescued people as the water rose.

The rain fell for days, sometimes 3 inches or more in a single hour, as streets became rivers and rivers ate up entire neighborhoods in southeast Louisiana.

Between Aug. 11 and Aug. 14, more than 20 inches of rain fell in and around East Baton Rouge, one of the hardest-hit parishes. And in some parishes in the region, as much as 2 feet of rain fell in 48 hours.

The National Weather Service says the likelihood that so much rain would fall in so little time was about one-tenth of 1 percent. A flood this bad should only happen once every thousand years.

A pair of scientists have a new hypothesis about why the female orgasm exists: It might have something to do with releasing an egg to be fertilized.

Scientists have puzzled over, and sometimes even questioned the existence of, a phenomenon that appears to have no physical effect on conception. While a male orgasm is crucial to impregnate a female, it is not obvious how a female orgasm affects whether she is impregnated.

The introduction of ride-sharing services such as Uber and Lyft hasn't had any impact on the number of fatalities related to drunken driving, a newly published study finds.

Researchers at the University of Southern California and Oxford University looked at the 100 most populated metropolitan areas, analyzing data from before and after the introduction of Uber and its competitors, and found that access to ride-sharing apps had no effect on traffic fatalities related to drinking alcohol.
