Talking Biotech with Dr. Kevin Folta

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.HPV and Other Cancers: https://www.sciencedirect.com/science/article/pii/S1043661825002762Shingles vaccine and dementia:  https://www.nature.com/articles/s41586-025-08800-xShingles vaccine and cardiovascular disease:  https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciaf440/8229580Singles  vaccine and cardiovascular disease:  https://academic.oup.com/eurheartj/article/46/30/2991/8124786

SummaryIn 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.Bluesky   @dubcovskylab.bsky.social‬

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.
