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...

Two decades ago the idea of growing crops indoors seemed like an excellent way to grow food closer to urban centers. Greenhouses and 100% indoor operations grew with significant investment.  Years later we see that major efforts have not succeeded.  What have we learned and where is the industry going?  We speak with Chris Higgins, President and CEO of HortAmericas, a company that supplies equipment to the industry.  We discuss the major hurdles in profitable greenhouse and indoor farm...

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...

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...

Great products and ideas are everywhere, yet limited by the ability to actually produce them in needed quantitites. The technologies from Sunflower Therapeutics enable bioprocess applications throughout the globe in a deployable unit with a small footprint. Dr. Kerry Love describes the technology and it's applications, along with the philosophy of a public benefit corporation that seeks to meet the needs from small startups to remote ressearchers. 

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...

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...

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. 

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. 

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.

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...

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...

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...
