Stay ConnectedTalking Biotech is a weekly podcast that uncovers the stories, ideas and research of people at the frontier of biology and engineering.
Each episode explores how science and technology will transform agriculture, protect the environment, and feed 10 billion people by 2050.
Interviews are led by Dr. Kevin Folta, a professor of molecular biology and genomics.

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.
After a three month hiatus the Talking Biotech Podcast is back. Today's episode is a visit with Colarbra CEO Aoi Senju about his view for the podcast, followed by synopsis of three major news stories that broke since the last Talking Biotech Podcast. The new format includes a video component, and I'll be speaking with panels and also discussing recent news stories. It is an exciting opportunity to capture a new audience, expand listenership, and provide new levels of programming to the popular format. Thank you for your patience and I hope you enjoy the new episodes. Kevin
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.
Even under the best conditions, crops need our assistance to survive the numerous threats that limit production. Classically, synthetic and natural compounds have been used to control insects, fungi and weeds, sometimes with negative collateral effects or fostering resistance of genetically tolerant genotypes. Todd Hauser from Trillium Ag describes his company's novel RNAi approach. RNAi can be used to target specific insect species, and his company's design and particle-based technology appears to offer safety, effectiveness, and specificity. We discuss the use of RNAi and how it may be a key point of crop protection strategies, along with its inherent challenges.
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.
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.
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.
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.
Recombinant DNA technologies once confined to the laboratory are now available to just about anyone. Is this a good thing or an extreme risk? David Ishee is self-described biohacker, dog breeder and mad scientist, and merges these passions in cutting edge DIY projects and educational tools. We discuss the opportunities and risks in DIY molecular biology, biohacking and democratization of modern genetic plant, animal and microbial genetic tools.
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.
