In this episode, we discuss the convergence of fermentation, perhaps the world's oldest biotechnology, with modern advancements in molecular biology to produce non-animal proteins as a sustainable food source. The exponential growth of the human population and our continued reliance on traditional processes for growing crops and raising animals for food risk widespread food security challenges, as we approach the limit of Earth's arable land. Cutting-edge biotechnology tools and novel applications of ancient fermentation processes allow us to modify bacteria, fungi, and other organisms, so we can leverage their unique properties to produce sustainable and nutritious—and tasty!—alternatives to animal-based proteins.

In this episode, we discuss the role of international screening efforts in protecting against the misuse of synthetically manufactured genetic materials. Rapid expansion in the capacity, affordability, and accessibility of gene synthesis—the ability to assemble genetic sequences from scratch—enables anyone with an internet connection to order custom genomes from vendors around the world. In the absence of consistent national or global regulatory frameworks, the responsibility falls on gene synthesis companies and researchers themselves to ensure that these services are not being misused to produce dangerous pathogens or their components. The International Gene Synthesis Consortium (IGSC) is an industry organization that supports the development and implementation of screening protocols for gene synthesis orders and customers to mitigate the risk of this misuse, in order to facilitate the broadest use of these technologies for peaceful purposes.

In this episode, we discuss advancements in gene drive capabilities and their potential as a tool to control vectors of zoonotic diseases. Gene drives are a natural process that preferentially propagates specific genetic traits through a population via sexual reproduction, and advances in genomic engineering have enabled scientists to harness this capability to target specific traits for spread in specific populations. They are best suited for use in animals that have short reproductive cycles and produce a large number of offspring, making them impractical for humans but immensely powerful for insects. Gene drives are being investigated as a tool to control mosquitoes' ability to procreate or their susceptibility to infections that could then spread to animals and humans, as a way to control diseases like malaria. Mr. Todi and Dr. Naik discuss the potential benefits of these capabilities, as well as barriers, costs, risks, and other considerations that factor into decisions regarding their future use.

In this episode, we discuss NASA's Office of Planetary Protection, which focuses on mitigating contamination risk for space missions. Their efforts cover both forward contamination—ie, contaminating extraterrestrial bodies with organisms from Earth—and backward contamination—ie, contaminating Earth with extraterrestrial life. Planetary protection functions much like laboratory biosafety, but on a much larger scale! The Planetary Protection office is responsible for developing and implementing the processes and standards necessary to ensure cleanliness and containment, and these considerations are part of the long-term planning that goes into all of NASA's space missions, including historical, current, and future efforts to return sample materials collected from the Moon, asteroids, and Mars.

This episode was recorded live, on site at the UN Palais des Nations in Geneva, Switzerland, as part of the BWC Global Forum side event hosted during the August 2023 meeting of the BWC Working Group on the Strengthening of the Convention. BWC states parties will convene as the Working Group semiannually during the BWC's 2023-26 Intersessional Period, with a mandate to develop concrete proposals for consideration at the 10th Review Conference in 2027. The BWC Global Forum side event coincided with Working Group debate on the need for science and technology review capacity for the BWC. The event was attended by dozens of BWC delegates and civil society experts from around the world.
Our podcast guests discussed gene synthesis screening and other biosecurity oversight programs, efforts to facilitate engagement between governments and civil society researchers on biosecurity priorities, and biosecurity education and awareness-raising programs for the next generation of cutting-edge scientists. Following the discussion, the guests engaged with audience members during a Q&A period. These discussions will inform BWC delegations on challenges and priorities associated with emerging biology and biotechnology capabilities as they work toward solutions to develop and implement science and technology review capacity for the treaty.

In this episode, we discuss efforts to develop large DNA viruses, such as herpesviruses, as vectors to deliver gene therapies, including advantages over other types of pathogen platforms. Notably, large viruses enable the delivery of larger genes for therapeutic purposes, and the characteristics of herpes simplex viruses (HSV) can allow gene therapies to be delivered over longer periods of time.
