| The GMO Tree You Never Heard About - Dr. Chris Dardick, USDA/ARS | 17 Aug 2024 | 00:35:11 | |
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. . | |||
| Anti-GMO Hawaii Memories; A Career in Ag Science - Dr. Steve Savage | 10 Aug 2024 | 01:00:14 | |
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. | |||

| Meredith Fensom: Update on Self-Limiting Mosquitoes | 14 May 2022 | 00:38:45 | |
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. | |||
| Dr. Oki O'Connor: New Drugs Targeting Dangerous Cholesterol | 07 May 2022 | 00:52:02 | |
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. | |||
| Dr. Awais Khan: Breeding the Next Amazing Apple | 30 Apr 2022 | 00:45:41 | |
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. | |||

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. , | |||
| Dr. Brandon McFadden: Consumer Sentiment and Gene Editing | 16 Apr 2022 | 00:47:43 | |
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. | |||
| Joe Landolina: Stopping Bleeding with Algal-Based Polymers | 09 Apr 2022 | 00:32:27 | |
A significant number of fatalities are due to blood loss following accidents, injuries or medical procedures. While many methods can stop catastrophic bleeds, they take time and are not always successful. This episode explores the process of inducing bleeding cessation with Joe Landolina of Cresilon. The company has devised a polymer from algae that is applied topically, and immediately stops the bleed. The science behind this innovation and potential applications are discussed. | |||
| Dr. Felicia Wu: Fungal Toxins in Food | 02 Apr 2022 | 00:50:38 | |
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. | |||
| Dr. Olly Peoples: Plastics and Fuels from Camelina | 26 Mar 2022 | 00:42:49 | |
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. | |||
| Dr. Arvinda Nath: Endogenous Retroviruses and Disease | 19 Mar 2022 | 00:47:29 | |
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.

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. | |||
| Journal Club - Were "High Levels" of Glyphosate Found in Sperm? - Dr. Andrea Love | 22 May 2024 | 00:28:57 | |
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.

| Jesus Martin-Garcia: New Therapies for HERV-Based Disease | 13 Feb 2022 | 00:39:14 | |
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.

| Trish Jordan: Hollywood and the Percy Schmeiser Story | 29 Jan 2022 | 00:53:31 | |
The story of Percy Schmeiser is a well known tale of big biotech against the little farmer from rural Saskatchewan. Schmeiser grew canola, and his outstanding harvests were due to herbicide tolerant seeds that he grew himself from materials obtained from means other than purchase. This violation of patent rights became the fodder of activist organizations, and a test of how a large company would respond to an unlicensed use of their technology. Schmeiser became the darling of anti-GMO activists, and he became the figurehead of a conversation about technology, patents, farmers’ rights, and seed sovereignty. This week’s podcast analyzes the film Percy vs. Goliath, a film that attempts to tell Schmeiser’s story. But what was accurate and what was fictionalized in the film? I spoke with Trish Jordan, who at the time was a communications lead at the Monsanto Corporation and followed the story very closely. She had a front-row seat for the legal proceedings and provides her analysis of the film’s veracity.

| Zack Johnson: The Importance of Telling Ag’s Story | 22 Jan 2022 | 00:50:23 | |
One of the criticisms of farmers is that they fail to engage the public to show what they do. It is understandable, their days are busy, competition is stiff, and farming selects for folks that shun the spotlight. Still it is critical to meet the public where they are, and that is exactly what Zack Johnson does. Zack is best known as Millennial Famer on YouTube. He posts video accounts of his daily work, but also interesting events that happen on his farm and around his area. The videos provide and educational and informative look at what happens on the farm, the technology, the hardships, the successes. In this episode we discuss his entry into public engagement, his motivations, and how being a celebrity farmer has affected his operation. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Dr. John Houston: Attacking Disease by Targeting Proteins | 15 Jan 2022 | 00:43:24 | |
Many diseases are rooted in the incorrect accumulation of proteins that regulate key cellular processes. Dozens of proteins control processes like cell division and cell death, and aberrant accumulation of these regulatory molecules can have profound health impacts. The Arvinas company has developed a means to specifically target specific proteins for degradation, exploiting a system called ubiqitination. Ubiqutin is a small molecular tag that sentences tagged proteins for degradation. Dr. John Houston is the CEO of Arvinas, and he describes the company’s progress in this exciting area of research and development. We discuss the technology, the progress, and the Arvinas pipeline. This alternative approach to controlling cellular processes holds great promise in the treatment of a number of human diseases. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Erik Carlson: Update on Transgenic (“GMO”) Chestnut | 08 Jan 2022 | 00:41:00 | |
The American Chestnut used to dominate Appalachian forests, but declined after a fungal disease was introduced to North America in the early 1900’s. Scientists have sought to restore the ecology and utility of this tree species by adding resistance through genetic engineering. For the backstory listen to Episode 9 (2015) of this podcast series. This week’s interview is with graduate student Erik Carlson. Erik recently published a paper in Molecular Plant Pathology that describes a new regulatory control of the gene that confers resistance to Chestnut Blight. We discuss the background of the project, where the project stands, and the regulatory environment of repatriating a forest with engineered trees. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Standardizing Therapeutic Protein Production in Plants - Jim Wilson | 18 May 2024 | 00:48:50 | |
Where many therapeutic compounds are raised in bacteria or fungi, plants sometimes offer many advantages as bioreactors. Capital and production costs are lower, and products may be edible instead of injectable. The problem tends to be standardization, and conditions that ensure that the desired proteins are produced This episode features Jim Wilson from Zea Biologics, where cleanrooms, precise regulation of all aspects of the plant growth environment, and massive data collection, allow for the production of biological compounds to treat everything from hemophilia to influenza. The compounds are bio-encapsulated, a patented process that allows oral delivery instead of injection. Using precision "pharming" drugs and be produced at a lower cost in less time, and the products are temperature stable, allowing wider distribution at lower cost, with a lower carbon footprint. www.zeabio.com | |||
| Cameron English: Is Biotechnology Just New Colonialism? | 01 Jan 2022 | 00:52:18 | |
Two unusually parallel articles emerged this week, both claiming that modern ag technology (as they say, “GMO”) is just another arm of colonial control of the Developing World. Both wordy, yet visible articles stoked remarkably common themes, without evidence, just opinion. Sadly, one of these was published in Scientific American, a popular magazine that continues to decline due to its injection of ideology in its opinion pieces that run counter to the scientific consensus. Cameron English is a journalist, the Director of Biosciences with the American Council for Science and Health. This week he wrote two stories this week, discussing these articles. In this episode of Talking Biotech Podcast we discuss the two articles, the decline of Scientific American, and how this new rhetoric is anti-biotech’s most recent salvo to stop technology from positively affecting the lives of the food insecure in the Developing World. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Wine Flavor: Merging Grape and Yeast Genomes | 25 Dec 2021 | 00:50:49 | |
Wine is a fermented beverage that has been enjoyed for millennia. While many may feel that the grapes used produce the flavors in the wine, a substantial contribution comes from the yeast and specialized bacteria that performs feats of biochemistry on the components lent by the grape itself. It is the merging of microbial and grape metabolism that provides each bottle with its distinct qualities. In this episode we speak with Dr. Sakkie Pretorius from Macquarie University. He has enjoyed a long career as an expert at understanding how wine flavor is derived. In this episode we discuss how the metabolism of microbes and grapes contribute to wine flavors, as well as the future of biotechnology in shaping wine flavors.

| The Challenges of Growing Plants in Space | 04 Dec 2021 | 00:36:26 | |
Sustained space travel and colonization will depend on the ability to grow food in extra-terrestrial environments. The fact that plants evolved on earth with cues from gravity, photoperiod, barometric pressure and other signals means that plants growing on space stations or other planets will face unique stresses, never previously encountered. Add to this the challenges of watering plants in microgravity, a dependence on artificial lighting, and limited access to crop protection and fertilization strategies, and the ability to produce crops in space is a realistic limiter of long-term human colonization of space. Dr. Anna-Lisa Paul has studied plant biology in space and in extreme earth environments to learn about how plants adapt to these challenges, and even how humans might have to adapt to care for them.

| Tiredness: Time for DNA Repair! | 27 Nov 2021 | 00:37:22 | |
We all know the feeling of tiredness, but what causes the urge to sleep? Prof. Lior Appelbaum discusses the link between sleepiness and DNA damage, as sensed through the accumulation of a protein known as PARP1. PARP1 is well known for its roles in DNA repair. Prof. Appelbaum’s team has examined PARP1 accumulation in animal models and shown strong evidence that the desire to sleep is triggered by DNA damage, and the desire to sleep involves action by PARP1. The conclusion is that tiredness should not be ignored, as it is a signal that there is some DNA damage to be corrected, and may play a role in long-term brain health. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Reprogramming T-Cells for Immunotherapies | 20 Nov 2021 | 00:35:32 | |
T Cells are the body’snatural defenders against pathogens. In the past they have been reprogrammed to recognize specific surface antigens of cancer cells to attack and destroy them. The approach has worked well against a variety of cancers. The limitation is that they addition of genetic material is limited by transfer techniques. This episode of the Talking Biotech Podcast discusses the new approach with Dr. Ken Drazan of Arsenal Bio. They have devised a strategy to place genetic material into T-cells from an afflicted patient that can now work against the disease in question. The approach uses gene editing, adding genetic material to T cells that allows them to recognize specific antigens, such as those associated with ovarian cancer.

| Insulin from Synthetic Biology | 06 Nov 2021 | 00:42:07 | |
Thirty million Americans depend on daily doses of insulin to stay alive. This small protein hormone is responsible for the regulation of blood sugar, and plays a key role in all aspects of physiology, as well as long-term effects on health. Despite its importance, the vast majority of insulin is produced off shore, leaving it vulnerable to supply chain disruptions that could be hazardous for many Americans. Domestic production is hindered by a variety of barriers, from production to regulatory. Cameron Owen is the CEO and Co-Founder of rBIO, and they are using a specially designed E. coli bacterium that focuses strictly on insulin production. This streamlining of the process around bacteria that commit the majority of resources into insulin production leads to minimizing side reactions and higher yields of the desired product. Making the production process more efficient means that this critical hormone may be produced at a lower price and without fear of supply chain production.

| Canadian Rules for Gene Editing - Jennifer Hubert | 11 May 2024 | 00:27:57 | |
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. | |||
| Integrated Molecular Strategies in Combating Disease | 23 Oct 2021 | 00:55:44 | |
New strategies in gene therapy are integrating multiple modern techniques to take on contemporary challenging diseases, such as solid-tumor cancers. Dr. Eric Ostertag of Poseida Therapeutics describes their transposon-based gene therapies that deliver useful gene replacements through biodegradable, tissue-targeted nanoparticles. This contrasts against the older gene therapy technologies that relied on viral delivery. In addition, Poseida offers new approaches in CAR-T cell therapies, genetic adjustment of native immune cells to target cancers. These One-time treatments appear to be promising in treating a variety of cancers using innovative strategies.

| Rediscovery of New Cancer Drugs | 09 Oct 2021 | 00:34:58 | |
Drug pipelines are thick with novel compounds that may have an effect on our most insidious diseases. However, most either fail early trials or are withdrawn because companies don’t see the return on investment of driving them forward. These shelved compounds still may have important roles in treating orphan diseases. The Children’s Tumor Foundation identifies these compounds lost to corporate expectations and re-analyzes them for therapeutic potential for other indications. Dr. Annette Bakker describes the process, the potential and the promise of compounds already identified in this partnership with pharmaceutical companies– testing their throwaways for new applications. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Evidence that Modern Birds are Dinosaurs | 02 Oct 2021 | 00:42:17 | |
The classical assumption was that the modern dinosaur lineage led directly to today’s reptiles. However, a growing suite of evidence has shown that modern birds more closely emulate prehistoric creatures. Today’s guests are Profs Alexander Vargas (University of Chile) and Joao Bothelo (Catholic University of Chile). Their work on comparative anatomy in embryos has unveiled additional similarities between birds and dinosaurs, and pharmacological and molecular evidence has shown that chicken embryos can be affected to present subtle dinosaur-like traits. Their work provides additional evidence that modern birds are actually modern avian dinosaurs. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Debunking Jeffrey Smith | 25 Sep 2021 | 02:16:13 | |
We must be dedicated to fighting back against false information in food and medicine. Jeffery Smith is a personality with no scientific training that has used disinformation to taint an important public discussion on biotechnology for over 25 years. One of the ways he does this is to hijack legitimate scientific venues, making them think he conveys actual information. He then uses their media to push his false information that ultimately affects the public trust in food, farming and medicine. Last week Smith was a guest on the Finding Genius Podcast, a podcast that features some excellent discussions with actual researchers. Smith and others like him have targeted science podcasts to promote their non-scientific ideas, using established scientific conduits to promulgate false claims. The point of this podcast is: 1. Illuminate how Smith propagates false information with uncited generalities, misrepresentation of actual science and innuendo. 2. Demonstrate how he (and folks like him) exploit credulous podcast/media hosts to gain an audience that may be unfamiliar with their misrepresentation of science and to promote their books/websites/documentaries. 3. To show how a reasonable podcast can fall prey to those that push false claims for agenda, politics and profits. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Influencing a Conversation with a #ScienceHug | 19 Sep 2021 | 00:39:01 | |
In this week of technical failures and personal challenges, this week’s podcast investigates the merits of civil conversation. In an angry online environment, can we use the tools of trust building, listening, and empathy to build trust and have greater influence? I discuss my current circumstances and the status of the social media discussion of vaccine hesitancy and genetic engineering. Can we influence the acceptance of good technology with a soft touch? Can we win more hearts and minds with kindness than with data? This is a very important episode I hope you’ll find illuminating. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Relax and Enjoy Your Food | 11 Sep 2021 | 00:43:10 | |
There is no such thing as bad food, it is just bad diets, so says Craig Good. Various life events caused him to rethink his relationship with food, and a keen skepticism led him to carefully evaluate the mistakes we make, the myths we accept, and the potential reasons we have an epidemic of diet-related illness and an internet packed with fad diets. The punchline is common sense, but comes after a discussion of food facts, psychology, and a prescription for healthy eating.

| Misinformation and GMOs | 04 Sep 2021 | 00:59:44 | |
How does misinformation about genetically engineered crops (GMOs) start and how do we correct it? These are questions asked by Prof. Robert Bird of the University of Connecticut. Prof. Bird discusses how an errant article can become the basis of misinformation spread, and how communicators can help push back against misinformation. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Glyphosate Residues and Dietary Exposure | 28 Aug 2021 | 01:04:40 | |
The herbicide glyphosate has been used for decades, with increased use paralleling the adoption of genetically engineered crops. The compound has a strong safety record and international regulatory consensus stating no unique health risks when used as directed. However, claims of cancer risk have increased in social media and websites, despite only cursory and/or circumstantial evidence of any actual causality. Juries have supported class-action lawsuits with substantial payouts based on cancer claims. The claims hold no weight if there is no exposure, and anti-glyphosate groups know this. Over the past decade there have been regular reports of finding glyphosate in beer, wine, hair, cereal, crackers and dozens of other products– with the implication that its presence is a cancer risk. However, there are two problems. First, most were performed with methods that could not be used for legitimate detection, and second, levels detected were extremely low, well below any levels that would constitute a health risk. A recent published peer-reviewed scholarly review by a team from an expert team from Bayer CropSciences compiled all of the claims, peer-reviewed and otherwise, and analyzed their methods. The synthesis is that many reports use methods that may not be extended to the specific analysis, they report insufficient results, or have legitimate detection with low amounts found that do not constitute a health risk. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Overcoming CAR-T Cell Bottlenecks - Dr. Andy Scharenberg | 04 May 2024 | 00:47:38 | |
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.

| Early Cancer Detection with Liquid Biopsy | 14 Aug 2021 | 00:28:37 | |
Many cancers are much more curable if detected early. However, the current suite of detection methods are slow, expensive and can’t detect a problem until it is advanced. Dr. Steven Quake of the Chan-Zukerberg Biohub is working with a group to perfect the liquid biopsy. Using just a patient’s blood, the test strive to identify cell-free RNA and /or DNA that often is shed into the bloodstream from solid tumors. Detection of such molecules may help diagnosticians identify cellular transformation events before symptoms ever are experienced. The relatively inexpensive and non-invasive test will likely be a central part of every annual physical, as it can detect problems long before they become problematic. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.

| Last Minute Guests! | 07 Aug 2021 | 01:02:16 | |
Yay for gremlins! Technical difficulties precluded the planned podcast, but that didn’t stop two good interviews from materializing a the last minute. Cameron Siggs is an attorney in south Florida. He came into a conversation in a Whole Foods Market that demonstrated the power of engagement and kind dialogue. In the second half we visit with registered dietitian Leah McGrath about farmers markets, seasonal produce and strange consumer expectations. Two great interviews with excellent information and ways to think about communicating our science.

| Activating Suites of Plant Genes with Cas9 | 31 Jul 2021 | 00:26:33 | |
The role of Cas9 as an editing/deletion nuclease has been well established, but can it be used to turn genes on? Dr. Yiping Qi of the University of Maryland has developed a system where Cas9’s specificity is used to recruit gene expression activation factors to plant promoters. The approach allows activation of sets of genes associated with disease resistance or other useful plant traits. # COLABRA # TALKING BIOTECH The Talking Biotech podcast is distinct from Dr. Kevin Folta's teaching and research roles at the University of Florida.
