In this Lunch with a Scientist episode, we discuss Genome Sequencing and Bioinformatics with National Institute of Standards and Technology (NIST) biologist Nate Olson, Ph.D.

Genetics is a fascinating topic of biology. Establishing relevance is a key component of student learning. To increase learning, this resource includes summaries and teaching guides for integrating four different podcasts into a genetics course. Lecturing through podcasts has been shown to be received well by students and improve their understanding of concepts. Using podcasts to provide context and significance to a course would further enhance their learning and interest in the course.

Biomolecular structure and function is emphasized as a core concept in a variety of community determined educational standards for biology and chemistry. Most curricula introduce students to the building blocks and principles of biomolecular structures, in introductory chapters of biology, biochemistry, cell biology, and chemistry courses, but very few engage students in actively visualizing and exploring biomolecular structures throughout the course. Conversations with faculty teaching introductory courses, and/or developing and piloting molecular case studies, helped uncover the need for new resources, and professional development to support introduction of biomolecular exploration. To address this need, a group of faculty participating in a Faculty Mentoring Network in Spring 2022, gathered together resources and lessons that they had independently developed and collaboratively developed additional ones. An overview of the lessons will be presented here. Interested users are invited to pilot the lessons in Fall 2022.

The exploitation of African elephants in the form of ivory poaching is exacerbated by warfare. The affects of this anthropogenic evolutionary force on the African savanna elephant (Loxodonta africana) in the Gorongoas National Park in Mozambique was investigated (Campbell-Staton, et. al. 2021) after the Mozambican civil war (1997-1992).  This multipart lesson is based on this research.  Here, we explore allele frequencies, phenotypic data, and the use of a chi-squared test to determine if the population is in Hardy-Weinberg Equilibrium.  Because one gene influencing tusklessness is X-linked, we also explore inheritance of the trait, using hemophilia as an example.  The data used in this part of the lesson are simulated data based on reports from Zambia.
