The Genomes of Parasites - Dr. Jessie Kissinger

Parasites are known contributors to human disease and suffering, spanning a wide range of organisms. Dr. Jessie Kissinger from the University of Georgia has spent the last two decades curating genomic data from hundreds of parasites, their vectors and hosts. The information helps researchers generate hypotheses about parasites, and presents a fertile resources for comparing genomes and understanding similarities and differences across this diverse set of organisms. VEuPathDB.org  (Vector and Eukaryotic Pathogens Resource Center)ClinEpiDB.org (Clinical and Epidemiological resource with DIY analyses and many BGMF studies) @jcklab   (Dr. Kissinger twitter)mango.ctegd.uga.edu  (lab website)

Cancer Misinformation - Dr. Skyler Johnson

"Cancer" is the generic term applying to any one of many cellular proliferative disorders that threaten normal physiology.  Various cancers have specific etiologies and require expertise in detection and treatment. New therapies are as innovative as they are promising, and a once dreaded prognosis now may have increased opportunity for cure, with better therapies on the horizon. But as it goes, with innovation comes resistance, and false information about cancer and its treatment flourish on social media. Today's guest is Dr. Skyler Johnson from the University of Utah Huntsman Cancer Institute. He describes his work as a radiation oncologist and how misinformation permeates online discussion of cancer, oftentimes with tragic outcomes.

Livestock, Climate Change, and Attacks on a Scientist - Dr. Frank Mitloehner

Animal agriculture contributes greenhouse gases that can influence climate change. One source in particular is cattle, as ruminant livestock produce methane from their specialized digestion, which is an especially potent greenhouse gas. Dr. Frank Mitloehner of the University of California Davis is an air quality expert in the area of ruminant biology. His research examines ways to mitigate the impact of livestock on climate, and his outreach efforts ensure that the information reaches the farmers and ranchers that can employ these strategies. In today's podcast we discuss the role of livestock in animal agriculture, as well as how he communicates new researchers to stakeholders. In the second half, we discuss an article in the New York Times that specifically targets Dr. Mitloehner, suggesting that big-money-industry taints his research and outreach outcomes. This baseless attack on a scientist's reputation is unsubstantiated by evidence, yet is penetrating, visible media clearly designed to harm a trusted public scientist and scholar. We discuss the impacts and how to scientists push through baseless allegations.

A Gene-Edited Vaccine Against Malaria - Dr. Stefan Kappe

The mosquito is the most deadly animal on earth. It vectors a plasmodium, a eukaryotic parasite that invades the liver of the host and ultimately attacks red blood cells.  There are  some therapies and preventatives, but a durable vaccine would be a game changer in the Developing World. Dr. Stefan Kappe and his team have developed a vaccine based on the weakened plasmodium parasite. They used CRISPR/Cas9 gene editing to disrupt genes required for life cycle progression, so the vaccinated can receive a vaccination and invoke a strong immunological response against the actual pathogen if encountered.  Clinical trials have demonstrated safety and efficacy, and paved the way for even more effective approaches that may be significant public health advances throughout the Developing World.

Seralini's Lumpy Rats - Ten Years Later

Ten years ago the biotech world froze and horrific images of three tumor-ridden rats penetrated the media. Social media erupted with messages of fear, and anti-biotech activists celebrated the scientific publication that conclusively linked biotech crops and an associated herbicide to cancer and early death. But at the same time a scientific community noted the shortcomings of the work. Eventually the paper was retracted, and independent research commissioned by the European Union failed to replicate the results. Still 10 years later, the three iconic rodents are used to dissuade the public from accepting biotechnology, and push a false narrative that was codified with the Seralini study. This week's podcast features the views of scientists and journalists, including Dr. Mary Mangan, Dr. Alison Van Eenennaam, Jon Entine, Joan Conrow, Michael Robin, Dr. Stuart Smyth, Dr. Myles Power and others.  The opinions expressed are those of the individual guests and not necessarily those of Kevin Folta, Colabra, or the University of Florida.

The Long COVID HERV Connection - Dr. Claudia Matteucci

Human endogenous retroviruses (HERVs) are genome-resident relics of ancient infections. They comprise 8% of the human genome, and are activated by viral infections. Proteins like HERV-W and HERV-K accumulate following infections and have been causally connected to Multiple Sclerosis and Amyotrophic Lateral Sclerosis. Scientists have now observed that SARS-CoV2 infection also induces expression of specific HERV proteins. Prof. Claudia Matteucci discusses the role of HERVs and their tie to COVID19 diagnosis and potentially as central players in long COVID.

Purple Tomatoes and Health - Dr. Cathie Martin

Anthocyanins are a class of plant pigments associated with healthful qualities in food. While research continues to assess their true health benefits in vivo, there is no question that the attractive fruits stimulate the senses and bring novelty to the diet. Dr. Cathie Martin of the John Innes Center in Norwich, England discusses the technology behind the purple tomato, its potential benefits to animal health, its effects on tomato shelf life, and the recent USDA nod to release of the purple tomato in the USA.

Rapid Detection of Sexually Transmitted Infections with Microfluidics - Dr. Anna Dixon

Sexually transmitted infections like chlamydial and gonorrhea are making a comeback, especially with younger demographics. Part of the problem is the stigma of examination and testing. These are not trivial infections, and can result in more complicated syndromes, which could include sterility or issues reproductive health. Early, discrete, confidential detection is key. Today's guest is Dr. Anna Dixon. She's the Chief Technology Officer of Binx Health. Her company has devised a lab-on-a-chip solution that provides fast and accurate diagnosis of specific infections in thirty minutes. Providing non-invasive, rapid and accurate, point-of-care detection can have profound roles in advancing patient care, as well as decreasing the incidence of disease in a population.

The Gut-Brain Axis: What it is, associated problems and new therapies. Nancy Thornberry

Communication between the digestive system and brain is much more intricate than previously thought.  The digestive epithelium is laced with sensors that monitor the contents of the gut, reporting back to the brain, stimulating appropriate hormones and digestive action to guide motility, chemistry, and absorption. This network is frequently referred to as the 'second brain' because of the dense neurophysiology at work. Recently it has been hypothesized that dysfunction in the gut-brain axis may be the basis for several immune and neurological disorders, suggesting that this neurological system may be an excellent drug target. Nancy Thornberry, CEO and Founder of Kallyope (Cal-EE-O-pay) describes the gut-brain axis, its role in digestive signaling, her company's novel drug discovery methods, and potential drug targets that may lead to innovative therapies for human health originating here in the second brain.
