Listener Request!  The YouTube channel Veritasium has been recognized by scientists and the public as a great source for scientific information. So what happened in the recent episode?  The episode originally entitled "Exposing the Monsanto Conspiracy" attempts to link the historic horrors of Agent Orange and contaminated herbicides with current claims against the herbicide glyphosate. To build the story this science channel relies on horrible sources and poor scholarship to build the illogical conclusion that because a company had a bad past, and anti-biotech activists and money-hungry lawyers build a narrative, then the herbicide must cause cancer. This, despite the overwhelming consensus from independent research and regulatory bodies that says there is no evidence of carcinogenicity at dietary or occupational exposure levels. This episode is designed to help the scientific listener understand the actual evidence and how even traditionally good communications efforts can become vehicles for anti-scientific campaigns. 

Anti-vaccination activists, including the US Health and Human Services Secretary, decry the risk of vaccination. In two recently developed vaccines the emerging story is that there is risk in not being vaccinated.  Analysis of large data sets shows that over the last 20 years, those vaccinated with the HPV vaccine have a lower incidence of cervical, penile and anal cancers, as they should.  But they also show lower incidence of other cancers as well, such as lung, blood and nervous system cancers. The shingles vaccines seem to have protective effects against dementia, heart disease and stroke. All of thse findings suggest that broader vaccination may have public health benefit. More importantly, these may be strategies against vaccine hesitancy, as families don't remember the sourge of polio and measles, but they likely know someone with cancer or dementia.  These findings could be a way to nucleate a shift in vaccine perception among evidence deniers.

In this episode of the Talking Biotech podcast, Dr. Andrey Zarur, CEO of Greenlight Biosciences, discusses the innovative applications of RNA technology in agriculture. The conversation covers the challenges of food security, the role of RNA in pest control, and the regulatory advantages of RNA-based products. Dr. Zarur highlights the efficacy and safety of RNA insecticides, fungicides, and herbicides, as well as the company's efforts to address bee health. The discussion also touches on public perception and the importance of transparent communication in biotechnology.

Summary

In this episode of the Talking Biotech podcast, Dr. Kevin Folta interviews Dr. Robert Tarone, a retired scientist with extensive experience in cancer statistics and experimental design. They discuss the controversial IARC monograph that classified glyphosate as a probable human carcinogen, the flaws in the evaluation process, and the implications of this classification on legal actions against glyphosate manufacturers. Dr. Tarone critiques the evidence used by IARC, emphasizing the lack of credible data linking glyphosate to cancer, and highlights the importance of rigorous scientific methodology in evaluating such claims.

In this episode of the Talking Biotech podcast, Kevin Folta and Dr. David Zaruk discuss the complexities surrounding glyphosate, particularly in light of the IARC Monograph 112 published a decade ago. They explore the implications of the reclassification of glyphosate as a probable carcinogen, the ensuing litigation, influence and corruption, and the ethical concerns regarding scientific integrity. The conversation delves into the role of the media, the influence of litigation finance, and the future of glyphosate in agriculture, emphasizing the need for transparency and evidence-based discussions over jury decisions.

This conversation explores the domestication of pigs, highlighting their importance in human society, the historical evidence of their domestication, and innovative research methods used to study their relationship with humans. Dr. Jiajing Wang from Dartmouth College discusses the significance of dental calculus in elucidaing pig diets and behaviors, as well as the complex interactions between humans and pigs throughout history.

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.
