Talking Biotech with Dr. Kevin Folta

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. 

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. , 

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. 

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. 

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. 

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.

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. 

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. 

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.
