Talking Biotech with Dr. Kevin Folta

In this conversation, Dr. Kevin Folta and Vance Crowe discuss the evolving landscape of agriculture communication, the rise of pseudoscience, and the cultural shifts affecting public trust in science. Vance shares his journey from working at Monsanto to founding Legacy Interviews, emphasizing the importance of capturing personal stories. They explore the challenges posed by influencers spreading misinformation about food safety and the implications of legal battles surrounding glyphosate. The discussion highlights the need for effective communication strategies in the face of growing skepticism towards scientific consensus. In this conversation, Vance Crowe and Kevin Folta discuss the evolving narrative surrounding glyphosate and its implications for agriculture. They explore the shift in public perception from anti-GMO sentiments to a focus on glyphosate litigation, the complexities of scientific communication, and the erosion of trust in institutions. The discussion highlights the challenges faced by the agricultural sector in light of potential chemical bans and the importance of rebuilding faith in science and its communicators.

Protein is essential for normal human development and physiology, yet is a significant global deficiency. World food staple crops like rice, wheat, cassava, and potato have relatively protein levels, yet constitute a significant portion of calories consumed. Dr. Ling Li of Mississippi State University has identified that overexpression of a gene called NF-YC4 can lead to higher protein accumulation. Her team used gene editing to remove promoter elements that suppress expression of this factor in soybeans and rice. The resulting plants accumulate more protein, and are curently being used in generating seed that may play an important role in global nutrition.

Two decades ago the idea of growing crops indoors seemed like an excellent way to grow food closer to urban centers. Greenhouses and 100% indoor operations grew with significant investment.  Years later we see that major efforts have not succeeded.  What have we learned and where is the industry going?  We speak with Chris Higgins, President and CEO of HortAmericas, a company that supplies equipment to the industry.  We discuss the major hurdles in profitable greenhouse and indoor farm agriculture, including capitalization, energy use, challenges ot the industry, organic certification. and other important issues. With co-host Donald Coon from the Agricultural Engineering Department at the Unviersity of Florida

We regularly discuss a small suite of commercial crops that have been genetically enhanced with transgenes.  However, one additional genotype was transformed long ago, and approved for use in the USA, Canada and EU-- but nobody talks about it much.  It is the plum resistant to plum pox virus (PPV), a devastating virus of stonefruits.  While rare in the USA, it is endemic throughout the rest of the northern hempisphere, and certainly could become a problem. Dr. Chris Dardick of the USDA-ARS in Kearneysville, WV talks about the plum, its history and current application. The resistant plum was developed by the USDA-ARS in the 1990s, using a similar approach to the successful papaya ringspot virus resistant papaya. The work is a foundational success of biotechnolgy, and an available strategy in the event the virus ever emerges. . 

In 2013 a number of county ordinances sought to end the use of biotech crops on various Hawaiian islands. Hawaii's warm year-'round climate permits several corn seasons a year, so seed corn for the mainland is produced in these locations. However, these technologies are not appreciated by a subset of the population, who see these companies as poisoning paradise. Drs. Steve Savage and Kevin Folta were brought to Kauai by the Hawaiian Crop Improvement Association to speak to business leaders and public audiences. They were met with protests and disdain, and this episode reflects on some of the experiences in public advocacy for sciecne. Dr. Savage also recounts his career in science and growing along with biotech breakthroughs. 

Great products and ideas are everywhere, yet limited by the ability to actually produce them in needed quantitites. The technologies from Sunflower Therapeutics enable bioprocess applications throughout the globe in a deployable unit with a small footprint. Dr. Kerry Love describes the technology and it's applications, along with the philosophy of a public benefit corporation that seeks to meet the needs from small startups to remote ressearchers. 

T-cells are a critical part of the adaptive immune system, actively targeting problematic invaders.  From pathogens to cancers, T-cells seek and destroy potentially dangerous cells, and maintain a memory of their presence. In today's episode Dr. Nigel McCracken describes this part of the adaptive immune system and how Virax Biolabs is using specialized tests to ascertain the presence and activity of T-cells activated by specific pathogens, such as Epstein-Barr Virus, cytomegalovirus, herpes virus and SARS-CoV2. We discuss the many applications of the technology and how the product pipeline may be employed in disease detection, to assess inflammatory response, and to gauge potential immunity to known pathogens.

Disinformation clouds the public understanding of science, especially technology in agriculture and medicine. So when a leading journal publishes false information, academic experts have an obligation to help correct the process. This may be done via a variety of methods, but cordial and collegial discussion is the first step. When that fails, notes to editors and authors are in order. When that fails, written point-by-point rebuttals are required. But what happens when that fails? An article in Pediatrics suggests that children are at special risk when consuming ingredients from gentically engineered (familiarly "GMO") crops. The article is rife with error and inuendo, and presents an opinion that lies diametric to the scientific consensus. Our efforts to correct the information have been met with 100% resistance, as editors, authors and reviwers have entrenched positions that are recalcitrant to revision, or even discussion. It destroys trust in food, technology, experts and a reputable journal. What should we do next? I discuss the situation with immunologist/microbiolgist Dr. Andrea Love and pediatrician Dr. Nicole Keller.

Wikipedia is the go-to source for many people when starting to research a subject. But is the information correct, or does the information even exist in Wikipedia at all?  Susan Gerbic has been training people to edit Wikipedia pages through the Gorilla Skeptics of Wikipedia project. They have edited tens of thousands of pages with over 16 million views. Susan describes the process as well as how you can be involved in correcting online false information. 

Crop genetic engineering has focused primarily on large-acreage crops like corn.  But what about the universe of specialty crops that tantalize consumers, things like blackberries or salad greens?  Pairwise has used precision twists on gene editing to change specific traits in fruit and vegetable crops. Pairwise founder and CEO, Dr. Tom Adams, discusses the current progress, general philosophy, and moonshot plans for bringing exciting new specialty crops to market.
