In today’s show and in future shows, Locally Sourced Science will be covering different scientific topics relating to the COVID-19 pandemic.

Today, you’ll hear a feature from veterinarian and Cornell graduate student Dr. Scarlett Lee. She speaks with Dr. Steven Osofsky, a wildlife veterinarian at the Cornell College of Veterinary Medicine.  He talks about the evidence that SARS CoV-2, the virus that causes COVID-19, came from wild species being sold in urban markets.  Osofsky then discusses why governments must put a stop to the trade and sale of wildlife species in order to conserve those species and maintain human, animal and environmental health.

Later in the show, in observance of early spring and the re-emergence of flora and fauna, you’ll hear a lively aural landscape of birds and bees.  Cornell student Ben DeMoras, who attended last summer’s workshop on applied science communication at Cornell’s Shoals Marine lab on Appledore Island, talks about some of the research being done on the Island.

In the month of March, we are recognizing the contributions of women scientists to all fields of science.   This is our last edition of our special Women’s History Month episodes. Of course, LSS will continue to post interviews of women scientists in upcoming shows.

Today, you’ll hear a podcast from Cornell graduate student and Locally Sourced Science contributor, Candice Limper.  She speaks with fellow graduate student Dr. Scarlett Lee from the Department of Microbiology and Immunology in the Cornell College of Veterinary Medicine.
In this interview, Dr. Lee, who is a veterinarian, talks about what is known so far about COVID-19 disease in humans of different ages.  She discusses the disease in light of her research interest, which is the effect of age on the immune system.

Dr. Jarra Jagne

Later in the show, you’ll hear an interview of Dr. Jarra Jagne, a veterinarian and Senior Extension Associate at the Animal Health Diagnostic Lab in the College of Veterinary Medicine at Cornell University.  She specializes in avian diseases and advises poultry producers on how to avoid disease outbreaks in their flocks. Here, she talks about zoonotic diseases such as SARS-CoV-2, the cause of COVID-19, that can spread from animals to humans.

Also, in today’s show, Liz Mahood’s presents a profile of Dr. Mary Guinan, the Dean of the School of Community Health Sciences at the University of Nevada, Las Vegas.

LSS 82: Women in Science 2

While this is another episode celebrating woman scientists, first we talk about the importance of handwashing and Ignac Semmelweis the father of handwashing.

Breast Tumor Cells

As you know, this month we are recognizing Women scientists, and the contributions that they are making to help us understand the diverse world around us and the worlds inside us. 

We recently spoke with Dr. Mingming Wu, Professor of Biological and Environmental Engineering in the College of Agriculture and Life Sciences.  Dr. Wu uses engineering and physics principles to understand biological processes.  She is interested in the forces that are exerted on cells, or by cells, when they move inside the body.  

In January of this year, Dr. Wu and colleagues published a study exploring how breast cancer tumor cells move inside the body.  The group created a device that could be used to study how breast cancer cells respond to the presence of a chemokine, a hormone released by lymph node immune cells that can attract tumor cells in the body. 

At the AAAS meeting in 2018, we interviewed Dr. Amelia Safi, who talked about the use of antibiotics in the dairy industry.

Lastly, we dedicated a segment to Tu Youyou, who won the “Nobel Prize in Physiology or Medicine” in 2015.

LSS 81: Women in Science I

In today’s show, you’ll hear an interview from Cornell undergraduate Rosemary Glos.  She spoke with Cornell Professor Chelsea Specht, the Barbara McClintock Professor in the School of Integrative Plant Science, where she studies the evolutionary biology of plants. In this interview, Dr. Specht talks about the value of the many natural history collections at Cornell.

Later in the show, you’ll hear a report on Ithaca College’s annual Women in Math day.  Esther Racoosin covered the February 8th event, where female high school students learned about the many reasons why they might want to consider majoring in math in college.

Janani Harihanan presents a profile of Dr. Janaki Ammal, the first woman scientist to receive a Ph.D. in Botany in the United States.

And Liz Mahood presents the Science News.
