| Are identical twins really identical? | 23 Mar 2021 | 00:15:32 | |
Identical twins are the gold standard in genetics to determine how much of a disease is genetic versus environmental. However, a recent study was published uncovering genetic differences between identical twins. In this week's episode we discuss embryonic development, the study itself, and what this could me with how we determine genetic causes behind diseases. SOURCES // What are GMOs?

| Can scientists treat glaucoma? | 16 Feb 2021 | 00:16:03 | |
Glaucoma is a debilitating disease where individuals lose their eyesight gradually. Often this happens later on in life and can sometimes be genetic. Scientists have been researching glaucoma and ways to help treat the disease. Recently, a study was published showing that scientists were able to reverse glaucoma-like symptoms in mice. In this podcast, we talk about the eye, dive into the study, and discuss potential implications of this research.

| What do we know about the new variants of coronavirus? | 02 Feb 2021 | 00:19:27 | |
Reports of new variants of coronavirus (a.k.a. SARS-CoV2) have surfaced in the U.S. in the past month. With these changes in the SARS-CoV2 genome come concerns that the COVID-19 vaccines developed by Moderna and Pfizer may not be as effective. Take a deep breathe - things are not as bleak as they seem! In this episode, we explain viral variants. How do they arise? And, importantly, what do we know about how these mutations change the current situation for COVID-19 (infection rate, vaccine immunity, symptoms)?

| What are GMOs? | 29 Dec 2020 | 00:16:49 | |
GMOs or genetically modified organisms have become quite a controversial topic in the past decade. In this podcast, we delve into the history behind GMOs, explain how they work, and discuss some of the technologies used to produce GMOs. This is part one of two and we plan to tackle why GMOs have become controversial in the next podcast. As always, our goal is not to tell you what to think but to give you the tools you need to make informed decisions and remove some of the fear and stigma associated with the science behind these controversial topics.

| What is Phrenology? | 03 Nov 2020 | 00:15:24 | |
In this week's Steministas, we discuss a recently published paper about predicting trustworthiness based on people's facial expressions from Nature Communication. This paper stirred up quite the controversy online. People are arguing that this paper promotes phrenology which is the study of people's qualities and characteristics based off of measuring their physical characteristics - specifically people's heads and faces. In this episode, we discuss the history of phrenology, what the paper analyzed, and the potential implications of a strong, scientific paper publishing a paper that seems to promote phrenology.

| How do hurricanes form? | 20 Oct 2020 | 00:14:24 | |
As we near the end of one of the most active hurricane seasons in decades, we can't help but wonder why this season is so much worse! To understand why, we dive into the factors that go into the making of a hurricane. We discuss what causes hurricanes, including some serious physics lessons involving magical paper airplanes that will blow your mind! We then briefly speculate on what could be causing the increase in frequency of these storms.

| Race and Medicine | 08 Sep 2020 | 00:21:23 | |
This is our second podcast in a two-part series about race. In this podcast, we discuss the role of race in medicine. We review the pros and cons of considering race in medicine. We also talk about the origins of some of the most common race-based medical stereotypes. Finally, beyond human interactions, we reveal how implicit biases can become engrained in the very algorithms and systems that decide our care and further increase health disparities.

| Is Race Genetic? | 25 Aug 2020 | 00:21:26 | |
This is our first podcast in a two-part series about race. In this podcast, we discuss the difficult topic of race and genetics through the lens of science and history. First, we discuss the history of racism beginning in the 1500s, then shift into how science was used to justify racism in both Europe and America. Throughout the podcast, we unpack the question of if race is genetic or just a social construct by delving into some genetic concepts about disease and ancestry. Finally, we discuss some genetic examples that are normally used to try and justify that race is genetic.

| Who was Henrietta Lacks? | 11 Aug 2020 | 00:26:51 | |
As part two of our series on unethical treatment of Black people in science and medicine, we tell the story of Henrietta Lacks. We all owe Henrietta thanks for the birth of HeLa cells. These cells, which came from a cancerous tumor removed from Henrietta, became the first human cell line. HeLa started a biological revolution! Unfortunately, Henrietta and the Lacks family were uninformed and treated poorly by the medical staff and researchers involved in the process. Her experience illustrates how important and divisive informed consent and tissue bioethics still is in this country.

| How did vitamins become vitamania? | 02 Jun 2020 | 00:23:06 | |
Vitamins have gone from unknown to a billion dollar industry within a century! In the previous episode we covered the basics of what vitamins are and how they were discovered. During this episode, we'll focus on how vitamins and supplements, the broader class of dietary additives, are marketed, evaluated, and regulated. It may shock you to learn that supplements are not routinely evaluated by the FDA! That's right, being in pill form does not make supplements equal to the level of scrutiny that we place on medicine and drugs in this country. If you use/need supplements, please check out our sources and listen for some strategies that you can use to research reliable sources of supplements!

| Coronavirus (SARS-CoV-2): What do we know? | 25 Feb 2020 | 00:29:04 | |
The Coronavirus, or SARS-CoV-2 as it is actually named, has in a matter of months killed over 1,170 people and sickened over 70,000 others with a pneumonia-like disease called COVID-19 (coronavirus disease 2019). A lot of questions are being asked about how it can spread, what the research says and what this means for the rest of the world. In this week's episode we talk about the basic biology behind SARs-CoV-2, we discuss recently published science about transmission dynamics, the reproduction value, incubation period and doubling time of the virus, and we end discussing China's response to the virus and the misplaced xenophobia people have during this time.

| What is a Genetics Dating App? | 11 Feb 2020 | 00:19:26 | |
With DNA sequencing getting cheaper and cheaper more and more people are using services like 23andme and Ancestry.com to find out about their health and ancestry. What if there was a way to choose who you date based on your genetics? Harvard scientist, George Church, is working on this idea in his app, Digid8 which will pair people up based on the likelihood of them not having a child with a genetic disease. In this episode we do a refreshment on DNA sequencing, talk about the diseases this app is planning to screen for and get into the whole ethical situation and discuss if the term eugenics is appropriate for this idea of a genetics dating app.

| What is the science behind essential oils? | 20 Apr 2021 | 00:14:22 | |
The claims about essential oils are many and include curing the flu, preventing headaches, soothing anxiety and many other claims. This has led to more people than ever putting oils on their skin, diffusing them into the air and even taking them in capsules. Is there potential harm from doing this or are the many claims legit and is there science to back them up? In this podcast we talk about some of the limitations with all essential oils, scientific studies that have shown negative effects about certain oils and scientific studies that have shown positive effects about certain oils.

| How is Down Syndrome tested for and what are the ethical implications of testing? | 06 Apr 2021 | 00:22:19 | |
Down Syndrome is a genetic disease characterized by mental and physical disabilities. It is often screened for early on in pregnancy and there is a correlation between countries that push early pregnancy screening and the percentage of babies with Down Syndrome being aborted. In this week's episode, we go over the genetics behind Down Syndrome, discuss the statistics of abortion of Down Syndrome babies being put out by other countries, and talk about the ethical implications behind testing for disabilities.
