On this week's episode of the podcast, we discuss protections in place for human research subjects. To start the conversation, we discuss some infamous examples of past injustices conducted in the name of "research" and the regulations they prompted as a result. We highlight four cases: the Holocaust experiments, the Tuskegee Syphilis Study, the work of James Marion Sims, and the case of Henrietta Lacks.
We spend some time detailing historical documents and regulations that were developed to pr
H-I-V...Not As Easy As 1-2-3: Eluding Vaccine Development for Decades
This week we answer a commonly encountered question: "why were we able to develop a COVID-19 vaccine in less than a year, but don't have a vaccine for HIV?"
We begin with the population health statistics of HIV globally to set the stage. We then do a primer on classification of viruses to underscore the fact that not all viruses are the same. We focus on SARS-CoV-2 and HIV specifically, and do a brief compare and contrast between the two viruses and virus families.
We focus specifically on the c
Separating pHact From pHiction: The Alkaline Diet Is Basic Nonsense
This week on the pod we discuss something we hear about all the time: the alkaline diet and alkaline water. Promised to prevent cancer and other ailments, this diet claims to be able to alter the pH of your body.
First we set the stage with a primer on what the pH scale is and how it relates to acidity or alkalinity of substances. We discuss the concept of homeostasis in the human body and how our organ and buffer systems ensure the pH of our blood and other compartments are tightly regulated.
Do Detox Diets and Cleanses Work? Not Nece-Celery!
On this episode, we discuss whether or not detox diets or juice cleanses have any evidence behind their claims.
We start off with a summary of what is considered a detox or cleanse, and compare it with what is actually classified as medical detoxification. We discuss the differences between the appearance of efficacy and actual efficacy of these diets, as well as the marketing tactics of this massive industry and misleading claims made about these products. We discuss some popular "detox" diets

No Need To Be Afraid, Don't Be Petrified, But You Should Know That Organic Foods Still Use Pesticides
On this week's episode, we take a little break from COVID-19 to talk about organics!
First, we refresh everyone’s memory from our GMO episodes, to clarify the difference between organic farming (a cultivation method) and GMO technology (a breeding method). We discuss what the organic label actually means and doesn't mean, and debunk the myth that organic products are pesticide-free. We talk about different examples of organic pesticides and how, at certain doses, they can actually be quite toxi
Is This The Real Life Or Is This Just Fallacy: Vaccine Myths Part 4
We are back again with the fourth (and final) episode in our series on debunking vaccine myths. In this week's episode, we focus specifically on the two COVID-19 vaccines (from Pfizer-BioNTech and Moderna). We kick things off with a discussion of the vaccine development timeline and address concerns that the vaccines were rushed; we break down the typical clinical trial timeline and how things are affected by the urgency of a pandemic. Next, we debunk the misconception that RNA vaccines are bran
Is This The Real Life Or Is This Just Fallacy: Vaccine Myths Part 3
On this week’s episode of the pod, we continue to debunk some of the most common vaccine myths, with an emphasis on adverse events. We talk about the Vaccine Adverse Event Reporting System (VAERS)-- both its utility and its shortcomings and remind folks that correlation does not equal causation. We also discuss why we have an immune response after a vaccine and briefly recap how vaccines work. We briefly discuss why assessing the risk of adverse events is not enough; we must weigh them against b
Is This The Real Life Or Is This Just Fallacy: Vaccine Myths Part 2
On this week's episode, we emphasize again that vaccine hesitancy is a top 10 threat to global health. We jump in and review the first four myths we debunked last week: that vaccines cause autism, that vaccines actually cause the diseases they aim to prevent, that vaccines contain fetal tissue, and that vaccines contain toxins and harmful substances.
We then move on to discuss and dispel the next four common myths we hear: that vaccines only affect individuals and it should be a personal choice
Is This The Real Life Or Is This Just Fallacy: Vaccine Myths Part 1
On this episode, we start by recapping the impact that vaccines have had on reducing disease burden in the U.S. and the damage that's being done by a recent increase in anti-vaxx sentiments and misinformation.
We then move on to debunk four of the most common vaccine myths including the oft-cited FALSE link between the MMR vaccine and autism, the false claim that vaccines can cause the diseases they are designed to prevent, that vaccines contain fetal tissue, and that vaccines contain toxins a
Don’t Bring COVID Home for the Holidays
On this week's episode of the pod, we give an update on the state of Covid-19, the latest statistics, and trends. We briefly review transmission routes and high-risk behaviors, as well as the different types of tests currently available. We try to drive home that tests should never be used as immunity passes! We give an update on our most promising vaccine candidates and remind you that though it's looking promising, we still have a long way to go.
From the Unbiased Scientists to you, we wish
Hey! Ho! GMO Myths Have Got To Go!
On this week's episode of the pod, we continue our discussion of genetically modified organisms (GMOs). We debunk common misconceptions and myths about GMOs, particularly with regard to the food industry. We spend some time discussing the labeling of foods as "non-GMO" and the different genetic modification techniques included under this umbrella term. We address the common misconception (that we "heard from the herd") that GMOs can change one's DNA, cause cancer and infertility, and also presen
Damn, Those Genes Look Good on You!
On this week’s episode, we are shifting gears to talk about GMOs. We set the stage by discussing the meaning of the term genetically modified (GM), and some of the different ways organisms are genetically modified, including historical methods such as selective breeding and hybridization. We provide an introduction into genetics and the idea of traits that can be inherited, and how that paved the way for genetic engineering technology over the last several hundred years.
We provide some specifi
You Can't Hurry Drugs, No, You'll Just Have to Wait
On this week's episode, we apply what we discussed about research studies, specifically clinical trials, to COVID-19 research into vaccines and treatments. We quickly review the phases of clinical trials, and provide a brief overview of the number of vaccine trials in each phase currently. We outline in more detail some key phase 3 vaccine trials that are ongoing, including a review of the status of each trial, the participant groups, and the type of vaccine technology being used. We discuss a n
You Down with RCTs? (Yeah, You Know Me!)
In this episode we geek out over research study design. We kick-off the episode with a primer on how research studies work and the factors that strengthen and weaken the validity of a study. We set the stage with a discussion of the "counterfactual" which guides the selection of study design. We talk about how research is hypothesis driven and seeks to address specific, measurable, and answerable questions. We discuss the difference between observational and experimental study designs (and give
Spilling The Immuni-tea on Supplements
In this episode, we discuss whether or not it is possible to “boost” our immune system. We start things off with a primer on immune system basics, including the different components of the immune system. We briefly touch on conditions where the immune system is overactive, in the case of allergies and autoimmune disorders.
We then introduce 8 key micronutrients necessary for proper immune function, and review the latest evidence on 3 of these: vitamin C, zinc, and vitamin D. Our “Heard from the
The Taming of the Flu
On this week's episode, we talk all about the flu! We start off with the basics of influenza and the different strains and mutations of the virus (and why they necessitate our getting an annual shot). Next, we answer our "Heard from the Herd" question about the need to get a flu shot even if you've never had the flu (lucky you!). We present recent population health estimates of disease burden and mortality and then take a trip down memory lane to discuss pandemics from years past. We also dispel
