Are identical twins really identical?

Épisode 40

mardi 23 mars 2021 • Durée 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.

Black Scientists in History: Part 2

Épisode 38

mardi 23 février 2021 • Durée 17:41

For Black History Month, we wanted to acknowledge the work being done today by talking about the contributions of Black scientists to our very own fields. In this episode, Emma and I cover geneticist Dr. Tracy Johnson (@TheTracyLab) and neuroscientist Dr. Nathan Smith (@SmithLab2018). We hope you enjoy hearing about their current research and service outside the lab!

Can scientists treat glaucoma?

Épisode 37

mardi 16 février 2021 • Durée 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?

Épisode 35

mardi 2 février 2021 • Durée 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)?
