Science Friday

Big news for tiny cats: an itty-bitty three-pound spotted cat from Bolivia—called the tilcayo—is the first new wild cat species described in more than a hundred years.
Tilcayo pics have been all over the news and social media, but there’s much more to tilcayo’s tale, including the surprising story behind its discovery.
Flora chats with Paola Nogales-Ascarrunz, the biologist who worked for nearly 10 years to describe this flashy feline. They also discuss how Paola met the tilcayo, why it was so hard to classify, and what the reaction has been in Bolivia.
Guest:
Paola Nogales-Ascarrunz is a National Geographic Explorer and biologist leading the Bolivian Felid Research and Conservation Program. She’s based in Bolivia.

In 2024, scientists using instruments on board the Lunar Reconnaissance Orbiter spacecraft spotted a new large impact crater on the surface of the moon. Tyler Powell joins host Flora Lichtman to describe what they found, and what scientists are learning about the lunar surface from studying it.
After, Sofia Sheikh describes different approaches to hunting for intelligent alien life through ‘technosignatures’. These are technological traces that could only be produced by intelligent life, like radio transmissions, industrial pollution, or city lights at night. Researchers from the SETI Institute have proposed sifting through lunar dust to look for tiny traces of a long-gone super advanced galactic civilization.
Guests:
Dr Tyler Powell is a planetary scientist at the Johns Hopkins Applied Physics Laboratory.
Dr. Sofia Sheikh is a Technosignature Research Scientist at the SETI Institute.

It’s a conversation at playgrounds and in classrooms: parents and teachers worry that kids who spent formative years at home during the COVID-19 pandemic are set back, emotionally, socially or academically. But what does science say? Did stay-at-home life permanently impact kids who lived through it? Joining host Flora Lichtman to dig into the research are child development experts Anna Johnson and Stephanie Jones.
Guests:
Dr. Anna Johnson, Professor of Psychology at Georgetown University in Washington D.C.

Dr. Stephanie Jones, Professor of Early Childhood Development at the Harvard Graduate School of Education in Cambridge, Massachusetts.

Football season is upon us and a new study is making headlines. Researchers found that roughly 1 in 4 NFL players will develop CTE, a neurodegenerative disease, in their lifetime. While most of us are not professional athletes, concussions are still a relatively common injury. Millions of Americans get concussions each year, but the exact number is hard to pin down because many people don’t seek treatment.
So what are we learning about how concussions affect the brain? And how are the best practices for treatment changing? To answer those questions and more Flora sits down with Teena Shetty, a former neurologist for the New York Giants and author of the new book “Healing the Brain.”
Guest:
Dr. Teena Shetty is a former neurologist for the New York Giants and founder of the Teena Shetty MD Concussion Clinic. She is also an associate professor of clinical neurology at Weill Cornell Medical College and author of “Healing the Brain.”
