Talking Biotech with Dr. Kevin Folta

 He jet-sets around the planet and writes letters to government officials, brandishing academic and military credentials. He speaks with authority as an affiliate of a land-grant university.  His claims rattle audiences and frighten regulators in the Developing World. Dr. Don M. Huber is a Professor Emeritus at Purdue University.  Over the last decade he has taken the point to denigrate agricultur...

 The Genetic Literacy Project is a popular science news website.  A diverse set of articles and viewpoints are presented, with original articles and news aggregated from the internet.  Over the last decade the website as been accused of simply being a “front” for the seed industry, even though there is no such tie to these businesses. Such accusations are levied by websites and NGOs that reject th...

We have two major problems.  Vanilla is mostly produced in a narrow set of unstable economies and the supply chains are especially vulnerable.  There is massive demand for vanilla flavoring.  The other major problem is plastic bottles.  Plastic waste from PET bottles creates a massive environmental hazard, and is purely unsustainable.  What if those bottles could be used as a substrate to produce...

 Analysis of massive genomic DNA sequence data indicates that gene transfer between similar species actually happened, and did so at a surprising rate.  Today’s podcast with Dr. Luke Dunning of University of Sheffield discusses his recent findings that indicate grasses are sharing genes with each other. It is an interesting discussion about horizontal gene transfer, from its mechanism, to its outc...

 One of the major objections to genetic engineering is that a DNA segment is transferred to the crop, and lands in a somewhat random location.  That’s because genetic engineering largely uses Agrobacterium to perform the genetic exchange.  But Agrobacterium came from nature, and there is significant evidence that DNA transfer events have been happening for thousands to millions of years.  Dr. Leon...

 Dr. Dan Wilson is a rising star of science communication. His popular YouTube channel Debunk the Funk provides entertaining and evidence-based dissection of issues around science, vaccination and COVID19.  In this issue of the Talking Biotech Podcast we discuss science communication, his motivations, and the recent dissection of the Disinformation Dozen.  We cover recent vaccine disinformation as...

 Peptides have increasingly emerging roles in cellular signaling and anti-microbial applications. Peptioids are cousins of their active peptide analogs, only  synthesized with a durable bond that helps the molecule evade cellular turnover mechanisms.  Dr. Gill Diamond of the University of Louisville discusses the chemistry of peptoids and their applications as anti-virals, including targeting SARS...

 A solar-powered animal?  There are species of sea slugs that consume algae, then integrate the chloroplasts into their own digestive cells.  There they function to fix carbon and essentially power the organism.  This phenomenon is known as kelptoplasty- stealing the autotrophic capacities of one organism for the slug’s benefit. This week’s podcast is a conversation with Dr. Sonia Cruz, a Principa...

The basis of aging and long-term degenerative disease have been formidable questions for scientists. Over the last decade several “methylation clocks” have been devised to examine modifications of DNA that match well with developmental state and disease presentation.  Dr. Ekaterina Rogaeva from the University of Toronto studies methylation clocks, especially as they associate with specific neurode...

Last week’s episode covered Alpha Gal Syndrome, the tick-induced allergy to beef and pork.  The same immunological response could also limit a recipient’s access to xenography or xenotransplantation, that is, the introduction of pig and cow tissues and organs for human benefit.  From valves to tendons to organs, the use of non-human animal parts is becoming increasingly common, but so is the insta...

 You find a tick on your skin and remove it.  The next day you eat a sausage and wind up in the emergency room in anaphylaxis.  After that, you can’t eat beef or pork without experiencing an intense allergic reaction.  This is alpha-gal syndrome, an allergy induced by the saliva of ticks bearing a simple oligosaccharide (compound sugar), and the body mounts an immune response against it.  The same...

Today’s podcast is an interview with New Zealander of the Year Dr. Siouxsie Wiles.  Dr. Wiles’ program uses bioluminesence as a marker to follow bacterial growth and disease progression.  Her work seeks to identify new antimicrobial compounds.  However, Dr. Wiles has become a go-to person in the discussion of COVID19, and has led public discourse on the realities of the pandemic. Her written work,...

While genomics approaches have opened a universe of new compounds in plants, the vast majority remain uncharacterized. Brightseed has employed an artificial intelligence platform to scan for novel compounds, with a goal to identify new chemicals that may play a role in human health.  Today’s podcast features Dr. Jim Flatt, CEO and Co-Founder of Brightseed.  He discusses the company’s pilot product...

Your DNA contains all of the information that makes you, you. With increasing understanding of the genetic basis of disease, the information in every cell may help anticipate, correct, or otherwise treat latent medical issues. The good news is that the cost of obtaining your personal DNA sequence is now less than the cost of a couple of concert tickets. At the same time, how is that information sa...

The COVID19 vaccines were produced in record time, an amazing feat. However, additional challenges have been revealed in their distribution.  Perhaps the most formidable barrier is the very last one– executing the vaccination.  For years anti-vaccination groups have soiled the internet and public discourse with false or exaggerated claims of vaccine dangers. They have appealed to the emotional wea...

This week’s podcast is a dissection of another popular podcast that features self-proclaimed experts in genetic engineering (familiarly GMO), and the falsehoods they propagate. Podcasts are great conduits to spread scientific information, but non-scientific views thrive also.  It is amazing to listen to the bad information, and the participants’ willing acceptance and amplification that goes uncha...

At its core, gene editing works to break gene function by creating errors in a DNA sequence at a specific location. The process works by creating a precise cut that is repaired by the cell’s repair mechanisms, and those processes can be error prone.  Those errors are the basis of the gene’s disruption.  But in a population of cells, how do you account for and catalog all of the changes?  Kevin Blo...

One of the major failures of addressing the COVID19 pandemic is the breakdown of testing.  The NFL and White House were able to  maintain business as usual because of daily, accurate testing. When the disease is detected, its spread can be controlled.  Jo Bhakdi of Quantgene talks about testing and how his company has scaled up testing solutions to at least apply them commercially to businesses wi...

Dr. Patrick Moore was a founding member of Greenpeace. In the years past its inception he worked tirelessly on ecological issues. Over time, he saw the group’s positions as less than scientific, leading to his defection.  Soon after he became a leading advocate for the deployment of Golden Rice, the pro-Vitamin A rice that was invented to alleviate blindness and illness caused by a missing micronu...

Bananas and other tropical crops have tremendous value, not just to farmers in the Developing World, but also as products that are enjoyed widely in highly industrialized nations.  However, crops like bananas and coffee are threatened by pathogens that could severely curtail cultivation and availability. Tropic Biosciences is taking on these problems using a unique approach– using gene editing to...

Radiation is a natural energy that constantly bombards us.  At the same time we have harnessed its power for medical imaging, therapeutics, energy and warfare.  Collateral damage from radiation exposure, even in critical therapeutic contexts, can have profound effects on cellular health and ultimately survival.  Dr. Fyodor Urnov of the University of Berkeley and the Innovative Genomics Institute i...

The story of biotechnology’s response to the pandemic is an amazing one, and we continue coverage of these events as they arise. Today guest host Dr. Asha Brunings speaks with virus and immunology expert Dr. Brianne Baker.  They discuss various topics of immunology with respect to the virus, discussing the new variants, the new vaccines, and a deep dive in to the mechanisms of immunity to the COVI...

Algae efficiently convert carbon dioxide into oils, and they are now being bred to generate a suite of compounds that may be synthesized into fuel and polymers that are the basis of biodegradable plastics.  Dr. Steve Mayfield is a Professor at the University of California San Diego, and the Director of the California Center for Algal Biotechnology.  His work with algae shows how this rapidly growi...

Certain aggressive cancers have profound effects on lifespan and quality of life. Patient prognosis can be grim, and therapies are harsh. Dr. Dan Peer of the University of Tel Aviv leads a group that has targeted gliomas and ovarian cancer with gene editing. Specifically, lipid nanoparticles are produced that target cancer cells, and introduce gene editing hardware that specifically inactivates ge...
