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, (https://droughtmonitor.unl.edu/) 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 (https://www.nobelprize.org/) 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.

In today’s episode, we feature an interview about research on Jupiter’s atmosphere. 

Candice Limper speaks with Yury Aglyamov, a graduate student in the Cornell Department of Astronomy. He discusses his analysis of data from the NASA Juno spacecraft that reveal lightning flashes in the atmosphere of the planet Jupiter. Aglyamov is an author on a paper recently published in Nature, “Small Lightning Flashes From Shallow Electrical Storms on Jupiter”. https://www.nature.com/articles/s41586-020-2532-1

Later in the show, Esther Racoosin speaks with Spencer Hill. He is a 3rd grade teacher at Cayuga Heights Elementary in the Ithaca City School District.

After schools closed in mid-March of this year due to COVID-19, Hill and his colleagues, Kim Snow and Emily Graber, decided to continue to instruct their students to practice simple design and build projects.

Hill applied for a Red and Gold grant from the Ithaca Public Education Initiative to provide funding for the supplies for the projects. In this episode, he speaks about what it was like to instruct the kids to do these projects at home with their families instead of with their peers at school.

LSS 95: Exploring Asteroid Bennu and “Shelter In Space” at Home

In this episode, you’ll hear an interview of three Ithaca College students, Antara Sen, Robert Melikyan and Salvatore Ferrone, who are studying the asteroid 101955 Bennu. Their advisor, Professor Beth Ellen Clark Joseph, is a scientist working on NASA mission OSIRIS-REx that will be touching down on the asteroid on October 20, in order to collect samples from the 500 meter diameter object.

Later in the show, you’ll hear Liz Mahood’s interview of Zoe Learner Ponterio, manager of the Spacecraft Planetary Imaging Facility at Cornell, also known as SPIF. The facility is closed to the public right now, due to COVID-19. But SPIF is offering an exciting remote learning program called “Shelter in Space” that students can explore at home. Visit https://cornellspif.com/ to learn more.

Today’s show starts off with an update about “2020 Migration Celebration”. The program usually is held on one day in September at the Cornell Lab of Ornithology, but this year you can learn about bird migration during a two-week series of virtual presentations.

LSS 94: Research Inspired by the COVID-19 Pandemic

In today’s episode, we interview scientists about new areas of research and exploration that were initiated in response to the COVID-19 pandemic.

Dr. Jennifer Surtees (photo courtesy of Dr. Surtees)

First off, Janani Hariharan interviews Dr. Jennifer Surtees, Associate Professor of Biochemistry at the University at Buffalo, and Co-Director of UB’s Genome, Environment and Microbiome Community of Excellence. Dr. Surtees recently sequenced dozens of SARS-CoV-2 isolates, obtained from the Erie County Department of Public Health.

During the interview, Surtees discusses how the SARS-CoV-2 RNA sequences reveal the geographical origins of the different viral isolates. You can hear about what SARS-CoV-2 genomes look like, how genomics can inform public health guidelines, and how to access a public database that contains information on SARS-CoV-2 strains from around the world.

To learn more about Dr. Surtees’ research, go to http://medicine.buffalo.edu/faculty/profile.html?ubit=jsurtees

Dr. Jason Guss (photo courtesy of Dr. Guss)

Later in the show, Esther Racoosin speaks with Dr. Jason Guss, a former graduate student of the Cornell Meinig School of Biomedical Engineering. Guss, together with fellow Cornell alum Dr. Apoorva Kiran, established Iterate Labs.

Iterate Labs initially developed wearable devices that could improve workplace ergonomic safety.  Now the devices are being modified to provide location awareness to prevent spread of SARS-CoV-2 virus in manufacturing workplaces. They also facilitate contact tracing when and if a worker contracts the virus. To learn more, visit https://iteratelabs.co/.

Today’s show concludes with an overview of the Cornell Atkinson Center for Sustainability new rapid-response grants that are funding a variety of COVID-19-related Cornell research projects.
