BioScience Talks

This episode is the second in our new oral history series, In Their Own Words. These pieces chronicle the stories of scientists who have made great contributions to their fields, particularly within the biological sciences. Each month, we will publish in the pages of BioScience, and on this podcast, the results of these conversations. Today, we are joined by Dr. Kent Holsinger, board of trustees distinguished professor of biology in the Department of Ecology and Evolutionary Biology at the University of Connecticut. He also previously served as president of the American Institute of Biological Sciences.

Note: Both the text and audio versions have been edited for clarity and length.

This episode marks the first in a new oral history series from BioScience, entitled In Their Own Words. These pieces chronicle the stories of scientists who have made great contributions to their fields, particularly within the biological sciences. Each month, we will publish in the pages of BioScience, and on this podcast, the results of these conversations. This first oral history is with Dr. Rita Colwell, a distinguished environmental microbiologist and scientific administrator, who previously served as president of the American Institute of Biological Sciences.

The Society for Integrative and Comparative Biology (SICB), an American Institute of Biological Sciences member society, fosters research, education, public awareness, and understanding of living organisms from molecules and cells to ecology and evolution. For this episode of BioScience Talks, we chatted with presenters and personnel from SICB's 2019 annual meeting, which was held earlier this year in Tampa, Florida. At the meeting, researchers shared work that highlights the value of interdisciplinary, cooperative science integrated across scales, geographies, and disciplines.

Please register for the 2020 Annual SICB Meeting in San Antonio, Texas. See http://sicb.org/meetings/2020 for details.

The BioScience Talks Impact Series focuses on the path from newly gained scientific knowledge to real-world effects, addressing questions such as How does a new vaccine find its way to physicians' offices? How do ecological discoveries result in new natural resource management paradigms? How do gene-editing techniques move from discovery to therapy? By following novel research discoveries from the lab and field to law books and store shelves, we find the answers and highlight the many ways that scientific research improves our lives.

In this inaugural episode, we interviewed Dr. Crystal Icenhour, CEO of Aperiomics, a life sciences company located in Loudoun County, Virginia. The company uses a technique called shotgun metagenomic sequencing identify every known bacteria, virus, fungus, and parasite (over 37,000) found in a given patient sample. Through this revolutionary technique, they are able to identify pathogens that would escape detection using traditional means. We chatted about the technology itself, and just as important, the pathway from innovation to helping patients in need.

By altering the heritability of certain traits, gene drive technologies have the potential to spread desired genes through wild populations. In practice, this could lead to mosquito populations that, for example, bear traits making them resistant to the spread of malaria. Despite the huge potential for improving human well-being, concern exists that gene drives could fail in the wild or spread beyond their intended target populations.

Writing in BioScience, Dr. Greg Backus, a postdoctoral researcher at the University of California, Davis, and Jason Delborne, Associate Professor of Science Policy and Society at North Carolina State University's Genetic Engineering and Society Center, describe a potential solution. Threshold-dependent gene drives could limit the spread of wild-released gene drives to target populations, increasing control and reducing the risk of unchecked spread. The authors joined us on this episode of BioScience Talks to discuss the potential of these gene drives—and also some of the questions of controllability, spread, and ecological uncertainty that relate to them.

In this episode of BioScience Talks, Christine Webb of Harvard University joins us to talk about the potential for widening the involvement of scientists who study animal behavior in ongoing discussions about animal treatment. She argues that because their work is often used to advance ethical arguments about animals, such as those concerning animal personhood, behavioral scientists are uniquely well positioned to engage more widely in these conversations, with potential benefits accruing to both fields.

In this episode of BioScience Talks, Mark Schwartz, of the University of California, Davis, joins us to talk about the National Park Service, and in particular, the challenges facing its oversight of over 400 individual units and 85 million acres of land. Park Service lands are faced with the same ecological difficulties that other wildlands are, and cultural and procedural shifts will be needed to face them, particularly in light of the rising specter of climate change.

In this episode of BioScience Talks, Derek R. Armitage of the University of Waterloo, Jennifer J. Silver of the University of Guelph, and Daniel K. Okamoto of Florida State University come on the show to talk about natural resource management. In their recent BioScience article, our guests and their coauthors described the integration of governance with quantitative measures--with an eye toward better managing natural resources to meet desirable social and ecological outcomes. Today, they join us to describe the article and provide some practical examples from fisheries management.

Joanne S. Tornow was selected as assistant director for the National Science Foundation's Directorate for Biological Sciences (BIO) in February 2019, following almost two decades with the foundation. Her duties ranged from program management to high-level leadership and strategic development, and she previously served as the head of BIO in an interim capacity. Prior to her time at the NSF, Tornow served on the faculty at Portland State University and the University of Southern Mississippi. She joins us on BioScience Talks to discuss the directorate's current operations and future plans. A written version of this conversation is available online and will be published in an upcoming issue of BioScience. Both versions have been edited for clarity.

Invasive species are a hot topic, both in scientific circles and among the public at large. Still, the mechanics of invasions are often opaque, and a broader understanding will be required in order to prevent—and respond to—future species introductions. In a world with ever-increasing trade and changing climate that often renders native species vulnerable, the need for this expanded understanding is acute.

Writing in BioScience, Dr. Mitch Cruzan, of Portland State University, in Oregon, describes the history of a particular invasive species, the slender false brome. Originally introduced in Oregon as part of a US Department of Agriculture program, the grass has undergone a hybridization process that enabled it to take hold in much of the state. By understanding the rapid adaptation of the false brome to Oregon's landscapes, it may be possible to unravel the mechanics of future invasions, before they endanger native species.
