Talking Biotech with Dr. Kevin Folta (Colabra)

While there are many views on Brexit, one certain benefit is the UK's self-governing role in scientific regulatory affairs. The EU's position on genetic engineering has perplexed its scientists, as they create solutions for EU farmers that may never be implemented. Now out from the EU's onerous non-scientific regulatory oversight, the UK may choose to deregulate gene editing. Cameron English talks about the proposed regulatory changes and how they may benefit the UK's farmers and scientists.  You can read his report here:  https://iea.org.uk/publications/harvest-time-why-the-uk-should-unleash-the-power-of-gene-editing/

Specific chemistries are used to protect crops from insects, weeds, fungi and other microbes. Legacy issues with some older pesticides led to restrictions or bans on their use. Unfortunately, suspicion remains around contemporary solutions, even though today's chemistries are highly  specific, with low toxicity to non-target organisms, including humans. Use of crop protection compounds is critical to all agriculture, including organic production. However, activist groups continue to manufacture fear, uncertainty and doubt to override what we really know about the detection of these compounds in food and the relative toxicity at levels found. Dr. Liza Dunn is an emergency medical doctor and toxicologist.  For the last several years she has been working with the Bayer Corporation, and has been a leading important conversations about pesticides, residues, and their potential for impacts on human health.

The companies on the front edge of pharmaceutical development have identified the value of massive data sets in the future of drug design. Ironically, personalization of therapies will be improved tremendously through examination of massive data sets. Dr. Michael Zaizac from Novartis of Europe discusses how his company has they have integrated artificial intelligence and analysis of patient data sets for new discoveries in patient care. 

This conversation explores the complex relationship between corn and Mexico, focusing on its cultural, economic, and agricultural significance. The discussion highlights the moratorium on genetically engineered (GM; GMO) corn, the public perception of biotechnology, and the impact of environmental NGOs on policy decisions. The conversation also delves into the perspectives of farmers regarding the need for access to biotechnology and the implications of recent presidential decrees on corn production in Mexico.

"Cancer" is the generic term applying to any one of many cellular proliferative disorders that threaten normal physiology.  Various cancers have specific etiologies and require expertise in detection and treatment. New therapies are as innovative as they are promising, and a once dreaded prognosis now may have increased opportunity for cure, with better therapies on the horizon. But as it goes, with innovation comes resistance, and false information about cancer and its treatment flourish on social media. Today's guest is Dr. Skyler Johnson from the University of Utah Huntsman Cancer Institute. He describes his work as a radiation oncologist and how misinformation permeates online discussion of cancer, oftentimes with tragic outcomes. 

In this episode of the Talking Biotech podcast, Kevin Folta interviews John Rizk, a pharmacist and epidemiologist, about M-Pox (formerly known as monkeypox). They discuss the emergence of M-Pox, its characteristics, transmission, symptoms, and recovery. The conversation also covers risk factors, diagnosis, vaccination strategies, treatment options, and the importance of health equity in access to vaccines. John emphasizes the need for more research and randomized control trials to better understand and manage M-Pox.

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. 

n this episode, Dr. Kevin Folta speaks with Joe Damond about the rapidly evolving landscape of life sciences, particularly focusing on gene and cell therapies. They discuss the exciting advancements in medical technology, the economic challenges associated with developing new therapies, and the implications for healthcare systems and patient access. The conversation also touches on the role of providers in administering these advanced treatments, the global disparities in access to innovative therapies, and the regulatory challenges that need to be addressed. Finally, they explore the potential of AI in transforming healthcare and the importance of ensuring equitable access to new medical technologies.

The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida. The views expressed on the show are those of Dr. Folta and his guests, and do not reflect the opinions of the university or Colabra.

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.

Gene editing with CRISPR/Cas, TALEN or other tools allows scientists to make directed and precise changes in DNA.  The technologies promise to transform agriculture and medicine. But the application of these technologies hinges on consumer sentiment. Dr. Brandon Mc Fadden is an agricultural economist that specializes in understanding what makes consumers tick. We have a conversation about gene editing, public sentiment, and how it varies between agriculture and medicine. 

Sexually transmitted infections like chlamydial and gonorrhea are making a comeback, especially with younger demographics. Part of the problem is the stigma of examination and testing. These are not trivial infections, and can result in more complicated syndromes, which could include sterility or issues reproductive health. Early, discrete, confidential detection is key. Today's guest is Dr. Anna Dixon. She's the Chief Technology Officer of Binx Health. Her company has devised a lab-on-a-chip solution that provides fast and accurate diagnosis of specific infections in thirty minutes. Providing non-invasive, rapid and accurate, point-of-care detection can have profound roles in advancing patient care, as well as decreasing the incidence of disease in a population. 

Robert F. Kennedy Jr. is recognized for his bad science around critical issues like vaccination and agricultural chemistry.  Recently he enjoyed a long-form, virtually uncontested platform on the Joe Rogan Experience where he rattled misinformation after falsehood about everything from vaccination to disease to glyphosate to cell phones. Because Rogan has a massive audience, this information is particularly dangerous. Here I refute, point-by-point, the false assertions made by Kennedy, and clearly show that he is simply a motivated disinformation hustler, and his false information must be corrected. In this podcast I refute his points with evidence, and show why he should not be trusted for information about medicine or agriculture. 

If you've ever publicly communicated enthusiasm for a new product or technology, you inevitably have been accused to being a shill for the company that produced it. It is a normal part of human psychology to assume there is an undisclosed motivation for someone's excitement, and it is based on legitimate concerns about how conflicts of interest can shape one's perceptions of associated science. We discuss the topic with Dr. Chris MacDonald from Toronto Metropolitan University.  

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.

The human brain is complex, but over the years massive data have been gathered regarding the relationship between structure and function.  From functional MRI to many other techniques, researchers slowly are resolving the relationship between brain anatomy and how it actually works. Dr. Stephan Doyen of Omniscient Neurotechnology have designed tools to parse massive collections of data relating brain structure to function, and now provide a set of tools to guide surgeons, as well as potentially serve as predictive tools in addressing challenging neurological disorders.

Immunotherapy is weaponizing the body's immune system against cancer or other disease. One of the most promising approaches is CAR-T cell therapy, yet as this technology has been implemented, it's limitations have been identified. Dr. Andy Scharenberg described the current drawbacks of CAR-T cells and how his company, Umoja, is re-engineering CAR-T cells in vivo to create more effective therapies, including approaches that can address solid tumors. Co-hosted by Donald Coon.

This episode has two parts. The first part discusses how Odylia Therapeutics is addressing rare disease, using a novel non-profit model. The second half address two rare genetic eye diseases and the approaches being designed to address them. Dr. Ashley Winslow, CEO/CSO of Odylia, describes how a non-profit is well suited to address these rare diseases, using strategies that leverage capacities in rare disease patient communities coupled to their expertise in drug discovery.  

Vaccination is a cornerstone of animal health, and is critically important in animal agricultural operations. A number of devastating livestock diseases are prevented with vaccination, yet vaccines have not been developed for some of the most devastating diseases for several reasons. Long before the COVID pandemic and its slate of next-gen vaccine strategies, Harris Vaccines was using rapidly adaptable RNA-based vaccine technologies. The current suite of RNA-based vaccines have been used successfully in swine for years, with many others in development. Today's discussion is with Joel Harris, CEO of Genvax.  We discuss the technology and its applications.

While DNA captures most of the fanfare, proteins are the catalytic and structural superstars of the cell. However, they can also become problematic. Cells have intricate mechanisms to remove damaged or mis-expressed proteins that could be deleterious to cellular function. This process is mediated by a process called ubiquitination, mediated by a special class of proteins called E3 ligases. Ubiquitin is the tag that's added that signals that a protein should be moved to the biochemical garbage can.  Dr. Juliet WIlliams of Kymera describes how their company has used modeling and A.I. to design molecular linkers that connect a protein that needs to be degraded with the machinery to tag it for destruction. The goal of this line of therapeutics is to target a suite of proteins that need to be degraded for normal health and development. Their pipeline contains multiple clinical and pre-clinical trials, and the approach is an exciting complement to other drug discovery methods. 

Recent reports criticized the lack of reproducibility in scientific publications, and this has profound effects on the public's trust in research results.  Today's interview is with Tim Errington, Director of Research at the Center for Open Science. The Center for Open Science has devised a series of strategies and tools that can help improve reproducibility, as well as offer collateral benefits to scientists. 

What can be learned about biology from massive datasets, and can that information unveil opportunities for new therapeutics?  This is the approach by Turbine.  Today's podcast discusses Turbine's approach with Dr. Dan Veres, CSO and Co-Founder of the company. He describes how data sets from multi-omics analysis are merged and analyzed to identify potential drug targets. and in silico information informs wet lab tests. The outcome is new therapeutics to treat recalcitrant disease.

While the vast majority of gene editing efforts have been confined to crop plants, animal gene editing holds tremendous promise. Efforts have demonstrated that naturally-occurring alleles could be reconstituted using site-specific nucleases, creating hornless dairy cattle and beef cattle with sex ratios skewed towards a higher proportion of males. These breakthroughs are just a sample of the powerful technology. Dr. Alison Van Eenennaam is a Cooperative Extension Specialist at the University of California Davis. She has been an academic leader in animal genetic engineering and public communication about new technology.

The podcast also features a conversation with Jilian Hendricks, a graduate student at the University of British Columbia. She is seeking assistance for a scholarly project, and would like to interview a number of scientists about gene editing. Her email is jhendric "at" mail.ubc.ca  

Upon sequencing the human genome, scientists were surprised to find that it is composed of about 8% viral sequence. These fossils are relics of ancient primate infections where retroviruses incorporated into the chromosome and became part of the human lineage. While these viral elements have contributed positively to speciation and development of specific human traits, they also have the capacity to become pathogenic. Dr. Advinda Nath is the Clinical Director of the National Institute of Neurological Disorders and Stroke. He joins Talking Biotech to share his experiences, knowledge and predictions in this exciting, emerging area of research. 

In this episode of the Talking Biotech podcast, Dr. Kevin Folta speaks with Steph van Grieken, CEO of Cradle, about the revolutionary intersection of AI and protein engineering. They discuss the central role of proteins in biological systems, the innovative software Cradle is developing to enhance protein design, and the implications of these advancements for therapeutics and industrial applications. The conversation also touches on the ethical considerations and potential misuse of this technology, as well as the future of AI in biology and its impact on environmental sustainability.

The process of animal development is a complex coordination of different genes through time.  At least that's what we thought.  Dr. Michael Levin from Tufts University is forcing us to rethink these processes, with impacts in medicine, cancers, correction of developmental defects and limb regeneration. , 

Mycotoxins are carcinogenic compounds that arise from specific fungal infections in various crop plants, with corn and peanut being key examples.  In the industrialized world, governments monitor relevant crops carefully, and install strict thresholds for presence of these dangerous compounds. But what about Developing World?  Today's podcast interviews Dr. Felicia Wu, Professor at Michigan State University. Dr. Wu has analyzed the risk associated with mycotoxins, and has studied how various technologies mitigate their effects. This is a shocking revelation about world food security, and a hopeful glance into methods of surveillance and new technology to improve global human health. 

Heart attack and stroke are leading causes of death worldwide. Current treatments are aimed at prevention-- using various medications to control the health of the circulatory system.  This week's podcast speaks with Dr. Oki O'Connor, Co-CEO of Underdog Pharmaceuticals. Dr. O'Connor discusses the cellular basis of atherosclerosis, and how modified cholesterol play a central role in its development.  We then discuss the ability of a cyclical carbohydrate called cyclodextrin to sequester cholesterol, and how this company has used computer modeling to modify cyclodextrins to limit and potentially reverse cardiovascular disease. There are also potential ramifications in Alzheimer's Disease prevention and treatment.  

After 8.5 years of weekly podcasts I'm going to take a 5 week break and plan new episodes for 2024.  I'm going through a medical glitch that has me unable to do my normal work. On top of this we're going to switch to an audio plus video format to find a wider audience. So check back in 2024 for the next episode. Have a great rest of 2023, thank you for listening, and looking forward to better times. 

While many global genomics analyzes gene variants or RNA expression products, the levels of proteins are usually the most informative.  At the same time, quantifying proteins is relatively difficult, especially when trying to obtain a snapshot of the proteome from a single cell or tissue. Dr. Parag Mallick of Stanford University and Nautilus Biotechnology describes the utility of high-throughput proteomics, and how the technology incorporates a novel detection method and machine learning to quantify large suites of proteins. The applications are almost endless and present great opportunities to understand how accumulation of specific proteins relates to biological function or disease states. 

Many diseases do not have cures, yet from deleterious mutations in the genome. Many of these are rare disorders that do not benefit from extensive research or drug development. Current therapies mask symptoms more than solve the basis of the disorder. Dietrich Stephan of NewBase describes a novel custom drug design platform that shows amazing potential in animal models. A small oligonucelotide with a specific backbone can bind to its complementary sequence in DNA or RNA, derailing RNA polymerase, or dissociating other regulatory proteins.  The design is highly specific and shows great promise against a myriad of disorders, including Myotonic Dystrophy, Huntington's Disease, and various cancers. This episode features a deep dive into molecular biology, so please do not hesitate to ask questions, it is interesting technology. 

Epigenetic regulation of gene expression occurs via many mechanisms.  One method is the methylation of regulatory sequences that control the expression of specific genes. Methylation is the addition of a small methyl group to specific bases of the DNA helix. Addition of a methyl group can change how the DNA blueprint is accessed and expressed.  Today's guest is Prof. Asaf Hellman. His group has found relationships between the methylation state of DNA and expression of genes associated with diabetes and cancers. Understanding these patterns may help inform predisposition to disease, as well as eventually causal factors and drug targets.  

The foundation of many modern consumer products begins with petroleum. Fossil fuels contain the building blocks of higher-complexity polymers, and are used in the creation of everything from high performance plastics in medical devices to your computer screen. But using petroleum use is not sustainable and has impacts in climate and pollution. What if the same molecular polymer backbones could be produced using biological organisms? Dr. Scott Franklin from Checkerspot explains how microalgae are being used to manufacture the fundamental building blocks of high performance polymers in a system that creates zero waste. These chemical backbones are used to create high-performance polymers that are fashioned into sporting goods for consumers interested in sustainability. 

Beer is a beverage derived from the fermentation of grain by yeast.  Hops impart their specific flavor and aroma notes. Together these ingredients produce a vast array of flavors and aromas that have become extremely popular in modern beer circles. Like any industrial workhorse organism, brewing yeast is significantly different from its wild antecedents. It has been bred to perform in fermentation, while creating metabolites that touch the senses of the consumer. Berkeley Yeast is taking the genetic improvement of yeast one step farther. Using modern biotechnology, their yeast strains are designed to create novel flavor and exciting aromas. Their efforts define a faster way to control the chemistry of fermentation, producing better products for consumers. 

How do new drug applications move forward to approval?  Four experts discuss the partnership between the FDA, the drug developer, and the data needed to move a product forward. It is a surprising discussion that reveals the depth of the FDA process.  Joined by Dr. Debra Webster, Dr. Julia Marre, Dr. Michael Matthews and Dr. Jonathan Helfgott. 

We are bombarded with information, but do we know what sources to trust and how to evaluate specific claims?  Melanie Tercek-King joins the podcast to discuss some fundamentals of critical thinking, and implement her tool kit to evaluate which claims have merit, and which might be best disregarded. 

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.

The 400th episode also represents the first episode of the 9th year-- an amazing run for a tiny, self-produced podcast.  Where did it come from?  In this episode I talk about the genesis of the Talking Biotech podcast, from the Vern Blazek Science Power Hour, to an arm twisting by Joe Rogan, to being banned from podcasting by my university-- this is a behind-the-scenes history of this effort. I also recognize the guests that are no longer with us, yet remain a vital part of this archive. 

We live in amazing times of technological advance, but how are the real benefits of new tech lost to an inflated sense of risk?  Dr. Felicia Wu from Michigan State University shares her expertise in describing the psychological basis of risk and applying it to questions like glyphosate and aspartame. 

Scientists are encouraged to step into the public conversation around controversial work, especially when that work seems to deliberately misinform, and can negatively affect public health.  A series of authors have used to COVID pandemic to use the peer-reviewed literature to push claims that are poorly supported by legitimate evidence. These papers find favorable review from poor-quality reviewers, leading to eventual publication, and earning the patina of legitimacy, despite the poor quality of the work. Dr. Lonni Besançon and an expert team responded to a paper online that presented no original research-- just a hypothesis that is supported by cherry picked data to support a conclusion. The team wrote a response to the journal, which was peer reviewed prior to publication, yet the journal still declined to print it. This conversation shows that the claims of silencing and censorship are not stopping bad information-- but we can identify cases where efforts to correct the information are rejected.

The mosquito is the most deadly animal on earth. It vectors a plasmodium, a eukaryotic parasite that invades the liver of the host and ultimately attacks red blood cells.  There are  some therapies and preventatives, but a durable vaccine would be a game changer in the Developing World. Dr. Stefan Kappe and his team have developed a vaccine based on the weakened plasmodium parasite. They used CRISPR/Cas9 gene editing to disrupt genes required for life cycle progression, so the vaccinated can receive a vaccination and invoke a strong immunological response against the actual pathogen if encountered.  Clinical trials have demonstrated safety and efficacy, and paved the way for even more effective approaches that may be significant public health advances throughout the Developing World.

The American chestnut was a dominant tree in many forests in the eastern United States. In the late 1800's an imported fungus spread rapidly throughout the range, destroying most of the trees in a matter of decades. Scientists at the State University of New York have engineered trees to host a gene from wheat that disarms the fungal invader, breaking the production of an acid required for infection. This strategy allows the tree and the fungus to live together without infection. Erik Carlson discusses the problem, the project, the push back and the current deregulation efforts to release the tree in the interest of repatriating its native range.

The potato is a world food staple, yet it is constantly threated by fungal and viral pathogens in all of its growing regions. Farmers combat these problems with chemistry, which cuts farmers profits and has potential consequences for applicators and the environment. Dr. David Douches from Michigan State University discusses the USAID project that installed a cassette of disease resistance genes from wild potato species in the cultivated potato. The result is a potato that can survive better in the Developing World, helping to ensure food security. 

Many diseases or disorders originate with a loss of cellular function.  Cell death or damage is at the root of many problems associated with aging or injury. But what if the cells lost could simply be replaced to restore function?  Brian Culley, CEO of Lineage Cell Therapeutics, discusses how his company has identified ways to generate specific cell types that can functionally replace lost cells in various contexts, restoring function. We discus applications in macular degeneration, hearing loss, and spinal cord injury, with potential applications in Type 1 diabetes, Parkinson's disease, and many future applications. 

This conversation explores the intersection of natural products and synthetic biology, emphasizing the importance of science communication and outreach. Julia Ball shares her passion for connecting the public with plant science, while Dr. Philip Zerbe discusses the potential of synthetic biology in producing valuable natural products, particularly terpenoids. The discussion highlights the challenges and opportunities in educating the public about biotechnology and the role of synthetic biology in sustainable drug production. In this conversation, Dr. Philipp Zerbe discusses the intersection of synthetic biology and natural products, focusing on the advancements in omics technologies and their role in bioactivity screening and pathway engineering. He highlights the recent breakthroughs in Taxol production, the complexities of intellectual property in synthetic biology, and the varying consumer perceptions of bioengineered products. Additionally, he provides insights into career guidance for students interested in these fields, emphasizing the importance of hands-on experience and networking.

Proteins define the structure and function of cells. The human genome encodes tens of thousands of proteins, yet we know surprisingly little about most of their functions. The Human Protein Atlas uses labor-intensive methods to identify the tissue localization of a significant catalog of human proteins. The reasoning is that if we know where a protein is expressed, we can begin to infer roles in cellular processes. The Human Protein Atlas is an open source resource of over 15 million images that define where different proteins are located. This week's podcast discusses the Atlas with Dr. Mathias Uhlen of the University of Stockholm. We speak about the origins of the database, how the work is done, and potential applications of this incredible resource. 

Despite being over half of the population women's health care lags behind other areas of drug development. The problem is caused by many facets, but is augmented by the fact that many of the conditions are not life threatening or are functions of aging. Sabrina Johnson, CEO of Daré Bioscience, discusses how the disparity exists, the pipeline of drugs that seek to mitigate female-specific conditions, and how smaller, leaner businesses can have significant impacts in this space. 

DNA has been an invaluable tool to make certain matches between a suspect and a crime. Since its early use in the 1980s, we have seen an explosion in DNA sequence availability, allowing forensic scientists to identify hypervariable regions of the genome that can assist in confirming a person's identity. However, there are many ethical issues surrounding its implementation, such as use of public and private databases (like 23 and Me) to identify a suspect. The discussion covers a breadth of forensic applications with Brian Hoey, Director of the Missouri State Police Crime Lab. 

Lipid nanoparticles have been around for decades, but they took a spotlight in the delivery of the COVID19 mRNA-based vaccines. This chemical cage can fuse with cell membranes and deliver a specific payload to a cell. While the delivery to specific cells is routine, are there ways to improve the system to have more specific therapeutic benefit. Dr. John Lewis of Entos discusses lipid nanoparticle chemistry and new formulations that exhibit enhanced capacity to target specific locations and deliver payloads more effectively. We also discuss the current therapies that may benefit from the new technologies. 

In this episode of the Talking Biotech podcast, Dr. Kevin Folta discusses the introduction of the Purple Tomato by Norfolk Healthy Produce. Dr. Nathan Pumplin, CEO of Norfolk Healthy Produce, shares insights on the development, consumer reception, and regulatory landscape surrounding this innovative product. The conversation highlights the importance of consumer education and the potential for biotechnology to address health and nutritional needs. Dr. Pumplin discusses the technology and genetic engineering involved, the importance of plant breeding, and the health benefits associated with anthocyanins. He emphasizes the company's commitment to creating high-quality products while addressing public perceptions of GMOs and the future of biotechnology in agriculture.

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.

This is an update on the American Chestnut Restoration Project, as discussed previously on the podcast. The American Chestnut dominated the forests of Appalachia until an imported fungus destroyed the entire range. Efforts to restore the chestnut and its ecology have employed a biotechnology approach, integrating a gene from wheat that limits the mechanism the fungus uses to attack the tree. Dr. Andy Newhouse and Erik Carlson join the podcast to discuss progress in the project.  

Parasites are known contributors to human disease and suffering, spanning a wide range of organisms. Dr. Jessie Kissinger from the University of Georgia has spent the last two decades curating genomic data from hundreds of parasites, their vectors and hosts. The information helps researchers generate hypotheses about parasites, and presents a fertile resources for comparing genomes and understanding similarities and differences across this diverse set of organisms.

We are bombarded by claims, and have access to the most information in human history, instantly.  How do we sort it out? What is real and what's not?  Who do we trust? These are major questions today, and affect everything from public health to the foundations of democracy in the USA.  From the news to the internet to the dinner table we are immersed in suspect information. How do we recognize and address conspiratorial thinking?  What mistakes do we make when analyzing a problem?  How can we recognize disinformation? Jon Guy has written a new book, Think Straight, that that addresses these questions perfectly, by providing a tool kit for dissection of information and claims. He covers a broad section of topics in what might be the most complete work on the subject of critical thinking and skepticism.

Gene editing is a powerful and specific technique that allows customized changes to DNA. Because there are no additional sequences transferred, and alternations match what could happen naturally over time, the technology is considered less invasive and less prone to regulatory oversight. That's true in the USA, Canada, China and other nations. However, the European Court of Justice determined that these techniques should be regulated in a manner identical to transgenics, where the EU has not approved such innovations in over two decades. EU scientists see how the EU is falling behind and after long may never catch up. The rejection of technology leads to a tremendous economic loss. Dr. Emma Kovak of the Breakthrough Institute discusses the current regulations, the proposed changes, and the dynamics of opposition to a good technology that could have profoundly positive impacts for people and the planet. 

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. 

As we age, the brain undergoes changes that lead to various disorders that affect physical ability and mental acuity. There are many processes at play, ranging from alterations in the extracellular environment, to accumulation of deleterious proteins, to a breakdown in connections between neurons. Can these processes be reversed?  Dr. Jean Herbert from the Albert Einstein School of Medicine has led efforts to reconstitute brain function through use of stem cells. Current steps in animal models may one day contribute to human therapies. 

The COVID19 pandemic was a challenge in public health, but became much worse through politicization of science and a thriving misinformation network. Over a short time, a cadre of personalities emerged in a willing media that made claims contrary to public health guidance, stoking suspicion and eroding trust in the messaging from public health experts. Dr. Jonathan Howard's book, "We Want Them Infected" is a collection of social and traditional media comments by contrarian physicians and media personalities that frame the dissent against public health guidance. Dr. Howard uses their own words to illustrate how a handful of personalities hijacked a health crisis to personally benefit, while providing false and dangerous information that clouded pandemic response, and eroded trust in vaccinations and other aspects of public health.

Advancement of a new drug from pre-clinical trials to clinical trials is a pivotal time in validation of its therapeutic effects and safety.  A panel of experts discusses the process. 

Many consumer products contain chemistries that originate from an unsustainable source. Dr. Chance Elliott VP of R&D at Amyris describes how his company is using synthetic biology to engineer yeast to produce these same compounds from sustainable substrates. We also discuss the current business climate, how companies change with new technology, as well as how to prepare for a future for jobs in this rapidly evolving space. 

Human Endogenous Retroviruses (HERVs) comprise 8% of the human genome and are relics of ancient infections, some dating back to pre-human primates.  These resident viral elements can be awakened by viral infections, and have been shown to be tightly associated with diseases like Multiple Sclerosis (MS) and Amyotrophic Lateral Sclerosis (ALS).  New data suggest a role for HERVs in the neurological symptoms of long COVID. Today's podcast features a conversation with Jesus Martin-Garcia, CEO and Co-Founder of GeNeuro. New therapies target the rogue proteins arising from these ancient viruses, and show promise in treating, if not reversing, disease progression.

Prion disorders are rare neurological diseases where a protein within the nervous system converts to a pathological form. The change in conformation affects other proteins, recruiting them to the misshapen, deleterious type. Chronic wasting disease is a neurological disease of deer, caused by prion conversion. In this episode Dr. Sandra Pritzkow from University of Texas Health - Houston describes prion related disease, and specifically the atypical transmission elements of chronic wasting disease. 

The "cell cycle" describes discrete steps in the process of cell division.  The progression is mediated by a series of gatekeeping biochemical activities that ensure complete replication of DNA, and surveil it for fidelity. Precise execution of cell cycle is necessary for normal growth and development.  At the same time, loss of cell cycle coordination can lead to aberrant cell proliferation that can become genetically unstable, a condition recognized as cancer. Many drugs target the enzymes that control cell cycle progression, and several appear to be attractive candidates for future therapeutics. Spiro Rombotis of Cyclacel Pharmaceuticals describes targeting the cell cycle, along with new drugs that show promise in slowing, arresting, or possibly reversing some challenging subtypes of cancers. 

Dr. Anne Simon is an expert in plant viruses.  She describes some of the current threats to plant biology, and discusses ways that viruses may be used to work for us, rather than against us. She also discusses her time as a technical advisor to The X Files series, and how that experience helped her to share science.

As the amount of plant genomic DNA sequence increases, scientists have detected DNA sequence information that simply does not conveniently fit into genome assemblies, and clearly appears to be from somewhere else. Dr. Lara Pereira from the University of Sheffield explains the surprising frequency of lateral gene transfer between grass species. The mechanism of crossing the species barrier is discussed, along with the frequency of horizontal transfer. We discuss the ramifications of unregulated integration of DNA into plant genomes and the perception of transgenic plants in the EU and other locations where crop genetic engineering is not viewed favorably. The results also suggest additional care when monitoring gene escape in transgenic grasses like maize.

Chronic inflammation goes hand-in-hand with many diseases, complicating symptoms and affecting routes of treatment. What is the molecular basis of inflammation, and can it be targeted by new drugs? Scientists have studied the molecular basis of the inflammatory response and have identified specific proteins that complex to initiate the response. New drugs are showing promise in breaking the inflammatory cascade. Studies of genealogical records revealed additional targets that modify known genetic pathways that contribute to Alzheimer's, cancers and cardiovascular disease. Dr. David Bearss from Halia Therapeutics explains the roles of inflammation and the mechanisms behind several drug candidates that are targeting chronic inflammation. 

Social media teems with false information about food and farming.  Influencers cover Instagram and Facebook with claims that food is poison and farmers are "dousing" crops in dangerous chemicals. It is a disinformation campaign that is founded on the fact that Americans make poor food and lifestyle choices, but instead of blaming our behaviors, they blame food and medicine, pushing bogus high-profit alternatives. But is there something nefarious here?  Has this online suspicion of our medical and food systems seeded by interests wishing to turn citizens against farmers and regulators, opting instead for fake alternatives and bogus nostrums?  It is a viable hypothesis. The war on seed oils, glyphosate and genetically engineered crops has re-ignited, despite minimal, if any, risk. Senate testimony by podcaster and "integrative nutritionist" Courtney Swan is dissected to demonstrate how wildly incorrect these folks are-- when speaking before a US Senate commitee!  This is how disinformation spread and now is being used to influence the highest eschelons of federal government. This all appears to be science and reason losing a damaging disinformation campaign using the internet and its complicit influencers to harm food and national security. 

The news reports say that scientists have found "high levels" of herbicide in human sperm, and suggest it is a cause of infertility. But what do the data really say? Dr. Andrea Love and I discuss the paper. A report by Vasseur et al., in the June 2024 Ecotoxicology and Environmental Safety entitled Glyphosate presence in human sperm: First report and positive correlation with oxidative stress in an infertile French population strongly implies a tight connection between the herbicide glyphosate and world population decline.  However, it is a classical case of overstepping the data. This group studied 128 men in a French infertility clinic and quantified glyphosate in in their blood and seminal fluids. Amazingly, they found parts per trillion, very low levels. They also never measured levels in sperm. They did measure sperm quantity and quality and they are just fine in individuals with glyphosate levels and those below detection. So there is no effect on sperm, consistent with previous studies. They do identify a correlation between glyphosate presence and two oxidative stress markers, but it is unclear what the "normal" range is, and it is very difficult to connect parts per trillion of a benign herbicide and meaningful physiological response. However, this was enough to ignite the media into connecting this trace of herbicide to crashing world populations, when people are most likely simply having smaller families.

Injury to organs frequently results in impaired function due to the formation of scar tissue. Heart attacks and chronic high blood pressure can induce the formation of pathogenic fibroblasts, cells that lose their original function, yet maintain some structural element of the injured tissue. The formation of fibrogenic tissue affects a significant portion of the population, and contributes to decline associated with many diseases, such as congestive heart failure or liver cirrhosis. A new technology uses targeted lipid nanoparticles to reprogram T-cells to attack pathogenic fibroblasts.  

Communication between the digestive system and brain is much more intricate than previously thought.  The digestive epithelium is laced with sensors that monitor the contents of the gut, reporting back to the brain, stimulating appropriate hormones and digestive action to guide motility, chemistry, and absorption. This network is frequently referred to as the 'second brain' because of the dense neurophysiology at work. Recently it has been hypothesized that dysfunction in the gut-brain axis may be the basis for several immune and neurological disorders, suggesting that this neurological system may be an excellent drug target. Nancy Thornberry, CEO and Founder of Kallyope (Cal-EE-O-pay) describes the gut-brain axis, its role in digestive signaling, her company's novel drug discovery methods, and potential drug targets that may lead to innovative therapies for human health originating here in the second brain. 

In a rapidly changing technology environment, how do established businesses tackle smart growth and continue transformative change?  In this special edition of Talking Biotech Podcast we examine the business climate of Regeneron, and how growth in the era of genomics and massive data sets from human health changed the process of drug discovery, but also changed how the company would respond to new opportunities and challenges. Dr. Jeffery Reid, Chief Data Officer, explains where the company was, and how it has changed with the rocketing pace of data acquisition and integration. 

Whereas we used to be challenged with finding information, today we are flooded with information, and our job has switched to vetting it's merits. Three students from the University of Florida spoke to me about their efforts in a national competition to study the origins of false information and communicate how to identify good information to the public. Tammy, Heather and Courtney were amazing guests that discussed their mission, along with a suite of online resources to help guide the public to quality information. 

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. 

The Pawpaw (Asimina triloba) is the largest native North American fruit, and grows wild throughout most temperate forests of the eastern United States and Canada, from southern Ontario to the Florida border. Several breeding efforts have sought to improve this tree crop, seeking mostly to improve fruit quality, especially post-harvest. The fruits feature a tropical flavor, a flesh that has been described as everything from marshmallow to banana, in a custard-like texture. Despite its flavorful appeal, few have experienced this fruit, mainly because of its perishable nature, and the fact that wildlife appreciate the fruit before humans ever get to it. However, a new initiative called Project Pawpaw seeks to improve the species for fruit production. Director Adam D'Angelo speaks about fundraising efforts to grow breeding populations, and utilize modern approaches to hasten development of improved pawpaws.

The company Color has taken innovative approaches to varied aspects of public health.  From at-home kits that can assess cancer risk, to efforts to curb COVID19, to finding attractive ways to make health care more accessible, Color has launched an array of programs that seek to improve public health.  Dr. Alicia Zhou is the Chief Science Officer of Color.  We discuss Color's efforts in cancer and disease detection, it's inroads into personalized, precision medicine, and a look at how technology may enable improved access to quality health care. Color is also a leader in constructing modern biobanks, repositories of data that can help shape healthcare outcomes in diverse communities. We also discuss careers in this evolving space, and how the business is adapting to a changing health care  delivery landscape in positive ways that benefit the patient and the system as a whole. 

Apples are a beloved fruit, with over 8000 varieties available worldwide. The apples in the grocery store represent just a tiny section of apple genetic potential, a few flavors that ship well and can be stored for a long period of time.  But today in the genomics era new tools seek to speed the breeding of apples to create new varieties, flavors, and disease resistance packages.  The goal is to help farmers and consumers produce the next generation of superior apple varieties.  With Dr. Awais Khan, apple breeder from Cornell University. 

Avocado consumption is rapidly increasing, and global production booming. However, the diversity of fruit choices is typically constrained to Hass.  There is tremendous diversity in avocado, featuring a range of flavors, oil content and seasonal availability. In this week’s podcast we speak with Eric Focht who has been running the breeding program at University of California in Riverside. We discuss the genetic origins, the breeding priorities, and next steps in the genetic improvement of the crop.

We're surrounded by microbes, many that are the basis of disease. Others have evolved resistance to our best antibiotics. Others may be weaponized for bioterrorism. Because microbial threats can evolve rapidly and grow quickly, early detection of a microbial threat is essential. Dr. Brad Perkins of Karius describes the threats of microbes, his company's novel approach to fast and easy test that can detect evidence of thousands of putative pathogens in a small blood sample, essentially overnight. We discuss the technology and its applications. The technology stands to be an important tool to ensure a lower-risk pathogen environment in medical facilities, as well as detect putative pathogens before they become major problems for a patient or broader population. 

This week's podcast has two parts. In the first section University of Idaho lactation specialist Dr. Shelley McGuire discusses the recent paper that claims to have found the herbicide glyphosate in breast milk. In the second half Gabe Ignetti from the Ecomodernist Society of North America discusses an environmental movement that embraces science, including biotechnology and nuclear power. 

If a genetic disorder can be detected in the developing fetus, it provides families and physicians vital information that can guide important decisions. From family planning to medical intervention, new molecular techniques are being employed to detect potential anomalies as early as 10 weeks after conception. The modern genetic counselor is an expert at communicating the results of these tests, building trust to advise decisions that benefit the parents and the child.  

Strategic partnerships are becoming more important in development and deployment of biotechnology solutions. Today's panel discusses the way partnerships are formed, some of the important considerations with IP and licensing, and how relationships are managed. 

There are many rare diseases that originate with a single letter change in DNA, and they can cause tremendous physical and financial hardship for families affected. Viral-based gene therapies have been a promise for decades, and modern technology is now bringing these concepts to fruition. Dr. Gaurav Shah, CEO of Rocket Pharma, describes the power of the current gene therapy approaches, along with the pipeline of potential therapeutics that could represent cures for rare disease. 

Immunotherapies represent a powerful suite of treatments that co-opt the immune system to target deleterious cellular conditions.  They have been effective with a series of cancers and other disorders. The problem is that development of new antibodies can be challenging for several technical reasons, but also because no two people are alike. Dr. Liang Schweizer of HiFiBio describes how her company is using single-cells and microfluidics to identify new antibodies that may be mobilized against discrete cellular targets, as well as what they have learned about heterogeneity between patients and how to identify specific biomarkers that could guide application of the most effective treatments. 

Canada has a unique approach to plant genetic improvement that follows the product, not the process. In other words, if there is potential risk from any genetic manipulation technique, from polyploidization to transgenic to gene edits, Canadian regulators assess the relative risk in the final product. But what does the regulatory climate look like going forward as gene editing becomes more routine? Today's podcast is a conversation with Jennifer Hubert, Executive Director of Biotechnology at Crop Life Canada. 

Insects cause massive losses in human health and agriculture. Scientists have implemented Sterile Insect Technique for over 50 years, a process to suppress populations by introducing genetically-damaged insects into natural settings. Upon mating, the offspring. Scientists have now used gene editing techniques to selectively suppress the Spotted Wing Drosophila, a costly pest in agricultural contexts.  Today's podcast is an interview with Dr. Nikolay Kandul, a scientist working with a team that has used an innovative Cas9/gene editing approach to suppress populations of this devastating and costly invasive pest. The application seeks to cut insecticide use and costs for farmers and consumers. 

Animal agriculture contributes greenhouse gases that can influence climate change. One source in particular is cattle, as ruminant livestock produce methane from their specialized digestion, which is an especially potent greenhouse gas. Dr. Frank Mitloehner of the University of California Davis is an air quality expert in the area of ruminant biology. His research examines ways to mitigate the impact of livestock on climate, and his outreach efforts ensure that the information reaches the farmers and ranchers that can employ these strategies. In today's podcast we discuss the role of livestock in animal agriculture, as well as how he communicates new researchers to stakeholders. In the second half, we discuss an article in the New York Times that specifically targets Dr. Mitloehner, suggesting that big-money-industry taints his research and outreach outcomes. This baseless attack on a scientist's reputation is unsubstantiated by evidence, yet is penetrating, visible media clearly designed to harm a trusted public scientist and scholar. We discuss the impacts and how to scientists push through baseless allegations.

Camelina (Camelina sativa) is an oilseed brassica that grows fast and produces many seeds. It grows in marginal soil and great resistance to disease and environmental stress.  That said, it is an ideal plant to use as a factory to produce a variety of metabolites that may be used in applications such as fuels and plastics, as well as a sources of healthy food oils and animal nutrition products.  Their resilience as a crop and rapid growth means that they may offer farmers an off-season cover crop that can add to soil health and produce important products.  This week's interview is an interview with Yield10's CEO Dr. Olly Peoples.  Yield10 is advancing the genetics of camelina to produce a variety of useful key polymers, nutrition products and food for animals, inside a cover crop that can expand profitable options for farmers.

Colorectal cancer is one of the leading causes of cancer death, but is remarkably treatable if caught early. Unfortunately, because of the invasive nature of the colonoscopy, many elect not to have this procedure done in a regular and timely manner. Colorectal cancers advance from normal cells through several distinct neoplasias, each with distinct patterns of gene expression. Today's guest is Dr. Erica Barnell from Geneoscopy.  They have devised a test to identify evidence of precancerous gene expression in the stool.  This advance makes early detection more feasible, along with a higher likelihood of frequent testing, at a significantly lower cost than outpatient procedures.

Ticks are significant disease vectors, with an emerging scope of pathologies associated with tick bites. New technologies have accelerated the ability to genetically engineer ticks, creating new opportunities to understand gene function in ticks, as well as potentially use gene editing to control numbers or affect disease vectoring. Dr. Monika Gulia-Nuss (University of Nevada, Reno) and Dr. Jason Rasgon (Penn State University) describe tick disease transmission, new transformation technology, and potential applications.  

Information has been weaponized, and the ability to create false information to achieve an ideological goal has never been more easy. Political polarization, science denial, and a shining, effective conduit of dissemination (the internet) allows anyone with an agenda to recruit the like minded, and produce compelling media to reinforce bankrupt ideas. Where did information warfare originate, what are its effects, and how do we fix it?  This week's podcast discusses the book, On Disinformation: How to Fight for Truth and Protect Democracy with author Dr. Lee McIntyre. The book presents a chilling description of who creates disinformation, how subscribes to it, and its long term effect on free society. Fortunately, solutions are proposed that can help curb the penetration of disinformation, particularly as it becomes more effective through artificial intelligence. 

Human endogenous retroviruses (HERVs) are genome-resident relics of ancient infections. They comprise 8% of the human genome, and are activated by viral infections. Proteins like HERV-W and HERV-K accumulate following infections and have been causally connected to Multiple Sclerosis and Amyotrophic Lateral Sclerosis. Scientists have now observed that SARS-CoV2 infection also induces expression of specific HERV proteins. Prof. Claudia Matteucci discusses the role of HERVs and their tie to COVID19 diagnosis and potentially as central players in long COVID. 

Mosquitoes are the world's most dangerous animals, vectoring dozens of diseases. One of the major disease vectors is Ades aegypti, an invasive insect with an ever-expanding range. Municipalities have turned to insecticides for control, which can impact beneficial insects. Sterile insect techniques, performed by mutagenizing mosquitoes to sterility, can work well in controlling insect populations. Over the last decade, Oxitec has advanced technologies that use a molecular techniques to repress development of mosquitoes in subsequent populations. Release of their genetically engineered males leads to decreasing populations of resident mosquitoes.  In this week's podcast we discuss the risks, benefits, and overall strategy, along with the company's public communications efforts, with the goal of increasing deployment of this technology when it can complement pubic health initiatives. 

In his new book Dr. Robert Paarlberg describes the current state of the food system, focusing on issues like industrial farming, organic farming, restaurants, biotechnology, and how technology will impact farming in the future.  In today's podcast we discuss some of the critical points of the book and what food and farming may look like in the future. 

Dogs are a recent species, and because of their close associations with humans have diverged into hundreds of breeds with specific behaviors, sizes and builds. There also is a great range in life expectancy and anticipated disease.  Dogs therefore provide an excellent model to study aging and aging-related disorders, as well as understand the genetics and associated factors of aging. Celine Halioua, the CEO of Loyal, joins the podcast to discuss research into dog genetics and the factors that influence aging, along with her company's attempts to find drugs that can attenuate the process, and possibly be extended to humans. 

The mythical Fountain of Youth may be an actual component of our physiology. Aging is not simply the body breaking down against the calendar, it is a coordinated series of molecular/biochemical changes that occur with time. There is an active hypothesis that later-life medical issues are not just happening as we age, but are actually caused by aging, meaning there are potential drug targets that may slow the process. BioAge performed -omics level analysis on populations of aging individuals, revealing patterns of proteins and metabolites that may be causal components of the aging process. New therapeutics seek to target aspects of human senescence, potentially delaying the onset of late-life disease. Dr. Eric Morgen of BioAge describes how his company has used a novel approach to identify new compounds that may play eventual roles in slowing the aging process. 

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. . 

There is tremendous variation in the plant kingdom, as plants have adapted to many ecological niches with discrete challenges. Part of adaptation is production of novel secondary metabolites, compounds not required for central metabolism that serve a role in the plant, such as defense or attraction of pollinators. The rainforest is replete with unusual plants and their resident metabolites. Indigenous peoples have identified therapeutic qualities of specific plants. How can this knowledge be transferred to aid those suffering beyond the rainforest? Lisa Conte is the CEO, President and Founder of Jaguar Health, a subsidiary of Napo Pharmaceuticals.  We discuss process of working with indigenous peoples to learn from their findings, then test and validate them in ways to identify novel mechanisms of action for use in modern medicine. 

Plant biologists use a set of tools to modulate gene expression. The well-established set of molecular switches are rather crude, with limited control of spatial or temporal expression.  Dr. James Lloyd discusses the newest tools in synthetic circuits, molecules that can tailor a response with a given input. These new tools add needed nuance to the regulation of gene expression and stand to revise how we control specific genes in the lab and field.
