How Millions Of Flies Can Help Stop The New World Screwworm
The New World screwworm has cattle ranchers, entomologists, and the federal government on edge. The pest was successfully eradicated from the US decades ago, but has recently been moving north from South America into Central America and Mexico, with concerns that it may cross the border into Texas. It’s notorious for laying eggs in the wounds of animals and slowly eating them from the inside out. Host Flora Lichtman speaks with entomologist Sonja Swiger about past efforts to get rid of the New World screwworm, and why that process involves dropping millions of bugs out of airplanes.Guest: Dr. Sonja Swiger is an entomologist and professor at Texas A&M in Stephenville, Texas.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Why Is The Scopes Trial Still Relevant 100 Years Later?
In July 1925, the Scopes “Monkey” Trial captivated the nation. On its face, the case was relatively straightforward: A Tennessee biology teacher named John Scopes was accused of teaching human evolution to his students. At the time, that was against state law. Both sides enlisted the help of big name lawyers to represent them, and the case turned into a national spectacle. But, why has the legacy of the case persisted? And what can it help us understand about our current moment?Host Ira Flatow talks with Brenda Wineapple, author of Keeping the Faith: God, Democracy, and the Trial that Riveted a Nation.

Why Don’t We Have A Vaccine For Lyme Disease?
It’s shaping up to be one of the worst tick years yet, and concerns about Lyme disease—which is transmitted through the bites of some species—are high. Aside from a short-lived vaccine released in the late 1990s, people have not had the opportunity to get vaccinated against Lyme disease. But if our dogs can get vaccinated, why can’t we? Host Flora Lichtman speaks with immunologist and Lyme disease expert Linden Hu about the ongoing quest for a vaccine against Lyme disease, and our evolving understanding of the disease. Guest: Dr. Linden Hu is a Professor of immunology at Tufts University School of Medicine.Read an article from SciFri about the research towards finding an anti-tick vaccine.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Is This PTSD Treatment Too Good To Be True?
About 7% of veterans experience post-traumatic stress disorder (PTSD), and that number can be closer to 30% for those who have served in a war zone. But PTSD has been treated pretty much the same way since the disorder was first recognized roughly four decades ago: Patients are instructed to revisit their trauma until the memory no longer creates an emotional response. This process can be so harrowing that over half of veterans are unable to complete the full course of treatment. But what if there was a way for PTSD treatment to be virtually painless?Host Flora Lichtman talks with Yasmin Tayag, staff writer at The Atlantic, who explored a controversial treatment called Reconsolidation of Traumatic Memories, and the challenges of even studying a treatment that bucks conventional wisdom. Guest: Yasmin Tayag is a staff reporter for The Atlantic.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Is It Time For A New Model Of The Universe?
For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is expanding faster than physics can explain, and our current models of it might be broken. Hosts Flora Lichtman and Ira Flatow talk with Wendy Freedman and Dan Scolnic, two cosmologists with different takes on this constant controversy.Guests: Wendy Freedman, a former team leader of the Hubble Key Project, is a professor of astronomy and astrophysics at the University of Chicago in Chicago, Illinois.Dr. Dan Scolnic is a cosmologist and associate professor of physics at Duke University in North Carolina.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
