The COVID19 pandemic was a challenge in public health, but became much worse through politicization of science and a thriving misinformation network. Over a short time, a cadre of personalities emerged in a willing media that made claims contrary to public health guidance, stoking suspicion and eroding trust in the messaging from public health experts. Dr. Jonathan Howard's book, "We Want Them Infected" is a collection of social and traditional media comments by contrarian physicians and media p...
Robert F. Kennedy Jr. is recognized for his bad science around critical issues like vaccination and agricultural chemistry. Recently he enjoyed a long-form, virtually uncontested platform on the Joe Rogan Experience where he rattled misinformation after falsehood about everything from vaccination to disease to glyphosate to cell phones. Because Rogan has a massive audience, this information is particularly dangerous. Here I refute, point-by-point, the false assertions made by Kennedy, and clearl...
The avocado is a wonderful fruit that is gaining in popularity, full of healthful oils and other nutrients. However, consumers consistently note the obvious drawback of the short life of fresh avocados, especially when used in recipes, like guacamole. Oxidative browning occurs within minutes, and causes food waste and supply chain loss. Green Venus is a technology company that has used site-specific nucleases to edit the genome of avocado. Dr. Jeff Touchman discusses the challenges and opportuni...
The 400th episode also represents the first episode of the 9th year-- an amazing run for a tiny, self-produced podcast. Where did it come from? In this episode I talk about the genesis of the Talking Biotech podcast, from the Vern Blazek Science Power Hour, to an arm twisting by Joe Rogan, to being banned from podcasting by my university-- this is a behind-the-scenes history of this effort. I also recognize the guests that are no longer with us, yet remain a vital part of this archive.
Vaccination is a cornerstone of animal health, and is critically important in animal agricultural operations. A number of devastating livestock diseases are prevented with vaccination, yet vaccines have not been developed for some of the most devastating diseases for several reasons.

Salmon are outstanding table fare, featuring flavor and nutrition. The AquAdvantage salmon is a genetically engineered salmon that is resistant to changes in growth due to seasonal fluctuation or the stresses encountered in traditional ocean-net salmon farms. Despite the advantages, the salmon has been caught in deregulation for many years, limiting consumer access. Silvia Wulf of AquAdvantage talks about the current status of availability, the technology, the criticisms and the future of the Aq...
The mythical Fountain of Youth may be an actual component of our physiology. Aging is not simply the body breaking down against the calendar, it is a coordinated series of molecular/biochemical changes that occur with time. There is an active hypothesis that later-life medical issues are not just happening as we age, but are actually caused by aging, meaning there are potential drug targets that may slow the process. BioAge performed -omics level analysis on populations of aging individuals, rev...

While there are many views on Brexit, one certain benefit is the UK's self-governing role in scientific regulatory affairs. The EU's position on genetic engineering has perplexed its scientists, as they create solutions for EU farmers that may never be implemented. Now out from the EU's onerous non-scientific regulatory oversight, the UK may choose to deregulate gene editing. Cameron English talks about the proposed regulatory changes and how they may benefit the UK's farmers and scientists. You...
The American chestnut was a dominant tree in many forests in the eastern United States. In the late 1800's an imported fungus spread rapidly throughout the range, destroying most of the trees in a matter of decades. Scientists at the State University of New York have engineered trees to host a gene from wheat that disarms the fungal invader, breaking the production of an acid required for infection. This strategy allows the tree and the fungus to live together without infection. Erik Carlson dis...
