    LSS 107: Under the Microscope

    LSS 107: Under the Microscope

    In today’s show, we hear interviews of two different professionals who use microscopes in their work.







    Mark Sarvary starts the show off by presenting a review of an exhibition called “The History of Glass and the Microscope”, that was on display in 2016 at the Corning Museum of Glass. You can still read about the exhibit here: (https://www.cmog.org/collection/exhibitions/microscopes).

    Our first interview of today’s show is with Dr. Brooks Crickard, an Assistant Professor in the Department of Molecular Biology and Genetics at Cornell University. He talks about his research using single molecule total internal reflection microscopy (TIRFM). This technique allows him to directly visualize proteins and protein complexes as they function on DNA in real-time. Crickard also discusses challenges he has faced as a new faculty member during the pandemic.

    In the second part of our show, you’ll hear an interview with Sten Anderson, a science teacher at DeWitt Middle school in Ithaca, New York. He recently taught his 7th grade students how to use foldscopes, flexible, waterproof, paper-based microscopes (www.foldscopes.com).  Students learned how to use foldscopes during both in-person and remote instruction.  Anderson guided students in how to gather, examine and record images of non-living and living specimens.  The purchase of a foldscope for each of his students was made possible by a Red and Gold Grant from the Ithaca Public Education Initiative (http://www.ipei.org).

    LSS 106: The story of the new Cornell CALS Dean and what is new in Alzheimer’s research

    LSS 106: The story of the new Cornell CALS Dean and what is new in Alzheimer’s research

    In this episode, Mark Sarvary interviewed the new dean of the College of Agriculture and Life Sciences. Dr. Benjamin Houlton began his term on October 1, 2020, as the Ronald P. Lynch Dean of the College of Agriculture and Life Sciences. He is also and a professor in the departments of Ecology and Evolutionary Biology and Global Development.







    Hear the story of how Dean Houlton almost received a Cornell Ph.D. and how he works with farmers in both California and in New York state to mitigate the impact of climate change.















    In the second interview, Candice Limper talked to Nancy Ruiz about her research at Cornell University, discussing what Alzheimer’s disease is and some of the symptoms. Nancy is a 4th year Ph.D. candidate and is trying to understand what factors contribute to the development of this disease as part of her thesis. During this interview, she describes a mouse model that she uses to understand the molecular mechanisms involved.















    In our Locally Birding segment, Kitty Gifford talked about the largest American woodpecker (and used some puns). Kitty mentioned in her segment this recent research: The Re-Establishment of Pileated Woodpeckers in New York City Following Nearly Two Centuries of Extirpation

    LSS 105: Science Education in Colleges and Universities – Remote learning and camera use study; and a new course “Diversity, Equity and Inclusion in STEM”

    LSS 105: Science Education in Colleges and Universities – Remote learning and camera use study; and a new course “Diversity, Equity and Inclusion in STEM”

    Kitty Gifford interviews Dr. Frank Castelli, Educational research postdoc with the Investigative Biology Teaching Laboratories at Cornell.







    Word cloud created by Frank Castelli using student responses.







    One of the greatest challenges in online learning is that students do not turn their cameras on and teachers speak into the void. Frank Castelli and his co-author, Mark Sarvary, studied this phenomenon and published a study in the Journal Ecology and Evolution titled  “Why Students Do Not Turn on Their Video Cameras During Online Classes and an Equitable and Inclusive Plan to Encourage Them to Do So,”







    The results of the study are discussed along with a plan any instructor can use to encourage camera use:







    1. Do NOT require video cameras to be turned on and do offer alternatives.







    2. Explicitly encourage camera use, explain why you are doing so, and establish the norm







    3. Address potential distractions and give breaks to help maintain attention.







    4. Use active learning techniques to keep students engaged and promote equity.







    5. Survey your students to understand their challenges.







    You can also read about the study in the Cornell Chronicle:







    Appearance, social norms keep students off Zoom cameras















    Janani Hariharan interviews Dr. Corrie Moreau, Martha N. and John C. Moser Professor of Arthropod Biosystematics and Biodiversity at Cornell University.







    Dr. Corrie Moreau







    Dr. Moreau created a seminar class called Diversity, Equity and Inclusion in STEM in Fall 2020. This interview touches on her motivation to create such a class especially in the wake of the George Floyd protests of 2020, the structure of the class and her favorite moments of the class. She also shared some recommendations for other educators who might want to design similar classes at their own institutions.

    LSS 104: Frog diseases, one health, pandemics, invasive species

    Esther Racoosin speaks with Dr. Kelly Zamudio, Professor in the Cornell Department of Ecology and Evolutionary Biology.







    A frog species that has been affected by the emergent pathogenic chytrid fungus.







    Dr. Zamudio studies how emergent pathogenic chytrid (KIT-rid) fungi species are affecting amphibian populations in the Americas.







    During the interview, Zamudio talks about how the principle of One Health is essential for both guiding the preservation of amphibian biodiversity around the world, as well as protecting human health.







    Candice Limper speaks with Dr. Jody Gangloff-Kaufmann who is who is a New York State Integrated Pest Management program official.

    Gangloff-Kaufmann talks about a new bug in town called the spotted lanternfly, which is an invasive plant hopper that is native to China and likely arrived in North America hidden on goods imported from Asia. While this is a beautiful bug with all its spots and colors, it is posing a problem for some businesspeople in the local area. The reason for this is because it is eating plants such as those in the vineyards and orchards, which is not so great for business.
