In the late 1990s an ethnobotanist named Dr. Paul Cox spent time in two villages on the Pacific island of Guam where a huge percentage of residents were dying of a neurodegenerative disorder that’s similar to Alzheimer’s Disease or ALS. He found links between the villagers’ diet, which included large fruit bats called flying foxes, and cyanobacteria toxins that were accumulating in the seeds of cycad trees, which the foxes would eat. This led to villagers having huge amounts of the toxins in their bodies. He joins us to talk about the work he did on Guam, and where the research is at today.

It’s becoming increasingly common for conservative political leaders in the United States — including here in Florida — to use language and put forward policies that conflate American identity with religious identity. Many are focusing on issues like abortion, same-sex marriage, and trans rights — and critics say this trend represents a rise in what’s called Christian Nationalism. Christian Nationalism is best summarized as the belief that the history and character of the United States is defined by Christianity, and that the government should take active steps to keep it that way. Our guest counts himself among its critics, and says that while supporters of Christian Nationalism portray it as a social movement, it’s actually a well-organized political movement that seeks to gain political power and to impose its vision on all of society. Rev. Paul Raushenbush is an ordained Baptist minister, and he is President and CEO of Interfaith Alliance, a national nonprofit founded in 1994 to advocate for religious freedom and pluralism in the U.S.

New legislation passed during the 2023 session and signed into law by Governor DeSantis makes a host of changes to election law in the state. Part of S.B. 7050 significantly restricts how third-party voter registration organizations like the League of Women Voters of Florida can operate. In response, the League of Women Voters of Florida is suing Florida Attorney General Ashley Moody and Secretary of State Cord Byrd, seeking to block provisions of the new omnibus election law that would restrict and penalize the organization’s civic engagement efforts.

For small-scale farmers in underdeveloped countries around the world, who often have no access to capital or most of the technologies and amenities we take for granted, the idea of being more sustainable isn’t something to strive for but a true necessity. Located in North Fort Myers on a 57-acre campus, the nonprofit ECHO has been working to disseminate information to help these farmers since 1981. They grow different varieties of plants, and test different growing techniques, in order to provide proven techniques and even seeds to small-scale farmers. They distribute more than 300 varieties of ECHO seeds. This information is sent out through their massive, global network of farmers and agriculturalists in more than 190 countries. We get an update on the work they do with their CEO, Dr. Abram Bicksler.

Bertha Vasquez spent most of her career in the classroom teaching science to middle schoolers in Miami-Dade County. She’s a passionate advocate for the scientific method and the many ways it’s made life better for humanity. And she’s a strong believer in skepticism when it comes to understanding the world around us, especially when extraordinary claims are made — like we see more and more these days thanks to the power of social media and the internet. Since retiring last year, Ms. Vasquez has taken on the role of Director of Education at the The Center for Inquiry, and Director of its Teacher Institute for Evolutionary Science. The CFI’s roots go back to the 1970s when Carl Sagan, Isaac Asimov, and other critical thinkers began seeing the need to mitigate growing belief in pseudoscience and paranormal claims using rational means and methods.

Project 2025 is not an entirely new concept. The Heritage Foundation has published what it calls Mandate for Leadership policy blueprints since 1979. The first one preceded the first Reagan administration. Over the decades they have outlined what conservatives hope to see out of a Republican administration, if that’s who wins the election. But, Project 2025 has a different tone and nature — and is far more detailed when it comes to exactly what policies it’s calling for, and just how they can be achieved.
