Talking Biotech with Dr. Kevin Folta

In this episode of the Talking Biotech podcast, Dr. Kevin Folta speaks with Dr. Pascal Geldsetzer about the relationship between the shingles vaccine and dementia. They discuss the prevalence of shingles, the current vaccination rates, and the potential implications of shingles vaccination on cognitive decline. The data come from a clever analysis of public health data that revealed this surprising result. Dr. Geldsetzer shares insights from his research, which suggests that the shingles vaccine may significantly reduce the risk of developing dementia. The conversation also covers the methodology behind the research, findings from various populations, and future directions for further studies in this area.

Summary

In this episode of the Talking Biotech Podcast, Kevin Folta speaks with Maria Rodtersman, a Ph.D. candidate at UC Davis, about her research on developing wheat to reduce gluten content, specifically targeting immunogenic proteins that trigger celiac disease. They discuss the significance of wheat as a staple crop, the differences between celiac disease and gluten sensitivity, and the use of radiation-induced mutations, the old-school brute force genetic methods used to create wheat lines with lower immunogenicity. The conversation also covers the challenges of wheat's hexaploid nature, the testing of modified wheat for bread quality and immunogenicity, and the future directions of this research.

The elucidation of DNA's structure led to questions about how it was replicated. Today's Talking Biotech Podcast commemorates the landmark experiments by Dr. Franklin Stahl, who died recently at the age of 95. The experiments have beed described as amont the most elegant in the history of biology, and used a simple test to determine the physical nature of DNA replication. This is a must-know story for the molecular biologist, and a spectacular example of a clever and definitive experiment for anyone that appreciates science. 

In this episode of the Talking Biotech Podcast, Dr. Kevin Folta discusses the challenges of misinformation in food science with Dr. Cami Ryan and registered dietitian Connie Diekman. They explore the role of social media and traditional media in spreading misinformation, the difficulties scientists face in communicating effectively, and the importance of peer review and other information-honing strategies to reinforce legitimate claims and de-fuse false information. The conversation emphasizes the need for better communication strategies, building trust with the public, and the necessity of teaching critical thinking and media literacy to consumers.

In this episode of the Talking Biotech Podcast (464) host Dr. Kevin Folta engages with journalist and author Michael Grunwald about his book 'We Are Eating the Earth.' They discuss the complex relationship between food production, climate change, and biotechnology, emphasizing the need for multifaceted solutions rather than single silver bullet approaches. Grunwald shares insights from his journey into understanding food production's impact on the environment, agroecology and regenerative farming, the challenges of public perception regarding biotechnology, and the importance of innovative practices in agriculture. The conversation also touches on the issues of food waste, biofuels, and the necessity for government investment in agricultural research and technology.

In this episode of the Talking Biotech podcast, Dr. Roger Cone discusses the complexities of obesity and eating disorders, emphasizing the role of brain circuits in regulating feeding behaviors. He explains the significance of GLP-1 agonists and melanocortin receptors in developing therapeutic approaches for conditions like obesity, anorexia, and cachexia. The conversation highlights the potential of combining these therapies to enhance treatment efficacy and the implications for public health. But most importantly, the approaches offer potential new therapies to address anorexia and cachexia that may prove to be as effective as GLP1 agonists have been for addressing obesity. 

This episode of the Talking Biotech podcast features Dr. Anita Shukla discussing the critical issue of antibiotic resistance and the innovative engineering solutions being explored to combat it. The conversation covers the evolutionary nature of antimicrobial resistance (AMR), the importance of antibiotics in healthcare, and the collaborative efforts of the Engineering Research Visioning Alliance (ERVA) to identify research priorities and strategies. Dr. Shukla emphasizes the need for novel therapeutic approaches, improved drug delivery systems, and the integration of advanced detection methods to address the growing challenge of AMR.

In this episode of the Talking Biotech podcast, Dr. Kevin Folta interviews Dr. Sarah Taber, who shares her journey from agricultural consulting to running for Ag Secretary in North Carolina. It is mostly a story of dedication to changing the norms and changing the rules to benefit more farmers, trying to break deeply entrenched interests to create real change. The conversation explores the challenges facing North Carolina agriculture, the need for innovative ideas to shift from traditional crops to more profitable produce, and the political landscape that influences agricultural policies. Sarah discusses her motivations for running, the strategies she employed during her campaign, and the lessons learned from the experience. The episode concludes with insights on the future of agriculture in North Carolina and advice for aspiring politicians.

In this episode of the Talking Biotech podcast, Dr. Kevin Folta discusses the current state of avian influenza, particularly the H5N1 strain, its history, zoonotic potential, and the implications for both poultry and human health. Into 2025 it was being detected in wild birds,domestic flocks, cattle and humans. Where did it go?  He highlights the importance of surveillance, the impact of the virus on domestic poultry production, and the ethical concerns surrounding euthanization methods. Folta also explores potential solutions, including vaccination and transgenic strategies that go unused although they are known to be effective. Finally, what is the status of emergency response?  The strategic stockpiles are gone, new mRNA strategies have been defunded. With no desire to protect animals and government policy failing to take precautions to protect humans, an avian influenza pandemic may be devastating. The current situation is discussed. 

This episode of the Talking Biotech podcast delves into the evolutionary significance and domestication history of corn (maize). Dr. Kevin Folta hosts a discussion with Regina Fairbanks and Dr. Jeffrey Ross-Ibarra from UC Davis, exploring the traits that enabled maize's domestication, the role of the TGA gene, and the implications for modern breeding. The conversation highlights the importance of understanding maize's genetic diversity and how modern tools may be used to unravel long standing questions about maize domestication.
