Inside a cavernous hangar at NASA’s Wallops Flight Facility along the Virginia coast, a gleaming white P-3 Orion aircraft sits parked under harsh floodlights. It’s just after midnight and a group of scientists, technicians and graduate students cluster underneath a wing, peering at a 5-inch crack in one of the ailerons that the pilot uses to maneuver the plane. Their disappointment is palpable. Learn about your ad choices: dovetail.prx.org/ad-choices

The ocean is normally a fairly noisy place, with the sounds of happy dolphins, lonely whales and diesel-chugging ships saturating the undersea world. But climate change may turn up the volume on this liquid symphony as warmer sea temperatures boost the volume of noise produced by the small but incredibly loud percussionist in this orchestra: the snapping shrimp. This crustacean uses its oversize claw as a bubble-forming pistol of sorts, snapping it at more than 210 decibels. Learn about your ad choices: dovetail.prx.org/ad-choices

In 1947, Kenneth Arnold was flying his CallAir A-2 between Chehalis and Yakima, Washington, when he took a detour to search for a downed Marine Corps aircraft. There was a reward for anyone who could find the plane, and who couldn’t use $5,000?

As California has descended into wildfire hell, with ever bigger blazes burning ever more intensely over the last few years, an unlikely firefighting hero has emerged: the goat. Officials in mountain cities in particular have been hiring herds to hoover up overgrown vegetation, creating fire breaks around the edges of towns. It’s what these ungulates—and their brethren the world over—are born to do. Learn about your ad choices: dovetail.prx.org/ad-choices

In late spring of 2012, climactic chaos descended upon the Midwest and Great Plains in the midst of the growing season. A drought is supposed to unfold on a timeline of seasons to years, but in the two weeks between June 12 and 26, the High Plains went from what a monitoring group called “abnormally dry” to “severe drought.

Alice Collins Plebuch, or Grandma Nerd, as her grandkids call her, is good at solving puzzles. She was among the first wave of computer programmers—when that term meant punching information on cards to be fed into mainframes. She has an analytical mind and is at ease with technology. Years ago, she began digging into her father’s history, hoping to find more about the man who’d grown up in an Irish-Catholic orphanage in New York.

What could be worse than getting the pneumonia-like illness now known as Covid-19? Getting it twice. That’s what Japanese government officials say may have happened to a female tour bus guide in Osaka. The woman was first diagnosed with Covid-19 in late January, according to a statement released by Osaka’s prefectural government Wednesday. She was discharged shortly after, once her symptoms had improved. A subsequent test came back negative for the virus. Learn about your ad choices: dovetail.prx.org/ad-choices
