In today’s episode, we explore how people perceive the risk of contracting COVID-19. We also discuss how humans can avoid passing COVID-19 to their beloved cat companions.

First off, you’ll hear Candice Limper’s interview of Cornell Professor Dr. Katherine McComas. She is a Professor of Communications in the College of Agriculture and Life Sciences and studies how people communicate about health, science, and environmental risks.

In the second half of today’s show, you’ll hear Candice Limper’s interview of Dr Alison Stout, a veterinarian who is pursuing her Ph.D. in Virology. She is a student in Dr. Gary Whittaker’s lab in the Department of Microbiology and Immunology at the Cornell College of Veterinary Medicine. In the interview, Dr. Stout talks about her research on feline coronaviruses and how humans can avoid passing SARS CoV-2 to their pets.

LSS 99: Lowering the Carbon Footprint of Mining Rare Earth Metals; Learning about and Finding Solutions to Climate Change

In today’s episode, we hear about a new technology that can lower the carbon footprint of an energy-intensive mining procedure. We also learn about the causes of climate change, and why the development of new technologies that keep carbon in the earth are so important.

To start off, Janani Hariharan interviews Dr. Buz Barstow from the Cornell Department of Biological and Environmental Engineering. Barstow talks about his research project that uses bacteria to extract rare earth elements in a clean, sustainable way. In this segment, you’ll hear about what rare earth elements are, why they’re important to us, what the current problems are in mining these minerals, and how Dr. Barstow’s team is working to solve some of these problems.

In our second interview, Esther Racoosin speaks with Dr. Ingrid Zabel, Climate Change Education Manager at the Paleontological Research Institution in Ithaca. Dr. Zabel discusses the new exhibit at the Museum of the Earth (MOE) in Ithaca, “Changing Climate: Our Future, Our Choices”. A virtual version of the exhibit is currently on display at the MOE website, The live version of the exhibit will open at the museum in late November.

LSS98: Effect of Urbanization on Evolution of Squirrel Coat Color; Science Communication Workshops


In today’s show, we speak with Dr. Brad Cosentino, Associate Professor of Biology at Hobart and William Smith Colleges in Geneva, New York.

He is the lead researcher on a grant from the National Science Foundation to study how urbanization may affect the evolution of coat color in the Eastern Gray Squirrel.

Listeners can learn more about the grant by visiting this link:

In the second part of the show, Candice Limper covers a recent virtual science writing conference held specifically for graduate students and post doctoral fellows who would like to learn more about science communication. She spoke with Jason Chang, a graduate student in the Cornell Meinig School of Biomedical Engineering, about the event, called ComSciCon-SciWri2020.

LSS 97: Plant Responses to Water Deficits; Harmful Algal Blooms

In this episode of Locally Sourced Science, we explore two phenomena related to climate change that may have significant effects on our local environment.

According to the U.S. Drought Monitor, ( Tompkins County and much of the Finger Lakes have been experiencing moderate drought conditions. Our first segment focuses on the ways that plants respond to drought. Esther Racoosin speaks with Dr. Taryn Bauerle, Associate Professor in the Cornell School of Integrative Plant Science, about her studies on how plants respond to stresses from water deficits.

In our second segment, we hear about the environmental implications of climate-related increases of harmful algal blooms in different ecosystems. Janani Hariharan talks to Dr. Katie Fiorella from Cornell University. Dr. Fiorella was recently awarded a National Science Foundation grant to study the economic and health effects of algal blooms on human communities in Kenya. We also hear about local algal blooms in the Finger Lakes area, and what they mean for our ecosystem. 

In our last segment of the show, Candice Limper provides a short history of the Nobel Prize ( and a quick glimpse into this year’s Nobel Prize in Chemistry, shared for the first time by two female scientists, Dr. Emmanuelle Charpentier and Dr. Jennifer A. Doudna.
