Science Friday

Back in May, a paper published in Nature Sustainability reignited a decades-old debate about coastal Louisiana: Should people leave? Climate researchers wrote that due to rising sea levels, coastal Louisiana has crossed the point of no return and that governments should be making plans now for places like New Orleans to relocate.

Jessica Dandridge-Smith, who runs The Water Collaborative in New Orleans, speaks with Flora about why this paper sparked such a strong reaction, and how she thinks about the possibility of relocation. Then, we chat with climate scientist A.R. Siders about how we can plan for the future while taking care of our communities in the present.

Guests:

Jessica Dandridge-Smith is the executive director of The Water Collaborative of Greater New Orleans.

Dr. A.R. Siders is an associate professor at the University of Delaware studying climate adaptations.

Pompeii is known for its disastrous end with the eruption of Mount Vesuvius, but for archeologists, what came before is just as interesting. Researchers are using artifacts left behind in the remarkably well-preserved Roman city to piece together what life was like for the thousands of people who lived there 2,000 years ago. 

A new book and television show analyze some of these clues to tell the stories of the ordinary people who faced this extraordinary event. Flora speaks with archaeobotanist Jess Venner, author of “The Lost Voices of Pompeii,” and actor Tom Hiddleston, host of National Geographic’s “Pompeii: Out of Time with Tom Hiddleston.”

An outbreak of the foodborne illness cyclosporiasis has sent thousands of people running to the bathroom this summer. Health officials have linked the outbreak to lettuce served at Taco Bell locations in five states, but there are still a lot of unanswered questions. Food safety expert Byron Chaves joins Flora to talk about the “explosive” nature of the illness and why pinpointing a source of the parasite has been so difficult.

Guest:

Dr. Byron Chaves is an associate extension specialist and professor in the Department of Food Science at Rutgers University in New Jersey.

The Nancy Grace Roman Space Telescope is scheduled for an early launch at the end of August. It will rest about a million miles from Earth at Lagrange point 2, where forces of gravity and motion balance out, allowing it to orbit the sun in sync with the Earth. The Roman Telescope is designed to collect masses of data that could inform questions about dark energy, dark matter, and exoplanets. Jackie Townsend, project manager for the mission, joins Host Flora Lichtman to discuss the telescope’s backstory, and what scientists hope it will do.

Then, turning from deep space to deep oceans, Anthony Tarantino of the Woods Hole Oceanographic Institution joins Flora to describe the recent maintenance and recertification process for the famous Alvin deep-sea submersible. It’s more than an oil change: The process involves disassembling the vehicle down to the bare frame. 

Guests:

Jackie Townsend is project manager for the Nancy Grace Roman Space Telescope mission. She’s based at NASA’s Goddard Space Flight Center. 

Anthony Tarantino is program manager for the Alvin Group at the Woods Hole Oceanographic Institution.

For two decades, a perplexing illness has been spreading: After a lone-star tick bite, people find themselves with a severe allergic reaction to red meat. The CDC estimates up to 450,000 people in the U.S. may be affected with alpha-gal syndrome, up from just a few dozen documented cases in 2009. New research finds that in some states, more than 30% of people are positive for alpha-gal antibodies—but not all of them have the syndrome.

Flora speaks with allergist Scott Commins, who has studied alpha-gal syndrome for nearly 20 years, to unpack this finding and next frontiers for treatment.

Guest:

Dr. Scott Commins is the William J. Yount Distinguished Professor of Medicine and associate chief for allergy and immunology at the UNC School of Medicine in Chapel Hill, North Carolina.
