In this episode of Genetics in Your World, GSA Early Career Scientist Multimedia Subcommittee member X has a conversation with Denise Ferkey of University at Buffalo about how natural variation in C. elegans responds to odors. Using hundreds of wild strains from the Caenorhabditis Natural Diversity Resource, the team found that wild worms were either as sensitive as the lab reference strain N2 to the aversive odorant 1-octanol or less so, and they traced this reduced avoidance to a single region on chromosome II. Read her paper titled, "Natural variation in C. elegans 1-octanol olfactory avoidance behavior," published in the October 2026 issue of G3: Genes|Genomes|Genetics: https://doi.org/10.1093/g3journal/jkag189.

In this episode of Genetics in Your World, GSA Early Career Scientist Multimedia Subcommittee co-chair Anindya Ganguly and member Racheal Asaolu interview Colin LaMont of University of Oslo. They discuss LaMont's work which presents a new mathematical method for calculating how strongly selection favors a genetic variant directly from an evolutionary tree, without knowledge of exact population history, finding that ancestral lineages act like strategists anticipating future selection rather than just responding to it in the moment.

In this episode of Genetics in Your World, GSA Early Career Scientist Multimedia Subcommittee member Allie Hutchings interviews Dr. Evan Dewey of Winthrop University about the functions of Blm helicase N-terminal IDR. Read Dr. Dewey's paper titled, “Functions of the Bloom syndrome helicase N-terminal intrinsically disordered region,” published in the March 2025 issue of GENETICS: https://doi.org/10.1093/genetics/iyaf005. Music: Loopster Kevin MacLeod (incompetech.com). Licensed under Creative Commons: By Attribution 3.0 License, http://creativecommons.org/licenses/by/3.0/   Podcast Notes: Bloom syndrome helicase (Blm) has important roles in maintaining genome stability. About half the protein is predicted to be intrinsically disordered (IDR), and its functions are poorly understood. The authors of this study identified regions that are locally conserved in closely related Drosophila species, then deleted these and assayed various functions. They find that each region is required for a subset of Blm functions. The authors’ modeling suggests these regions adopt structure in complex with Top2alpha and the results provide novel insights into Blm IDR functions.   Dr. Evan Dewey would like to acknowledge the following colleagues: Colleen C. Bereda, Dr. Jeff Sekelsky, Dr. Christopher A Johnston, Denise Soroka, Dr. Mitch McVey, Carolyn Turcotte, Dr. Nila Pazhayam, Mohamed A. Nasr, Priscila Santa Rosa, Susan McMahan, Dr. Robert J.

Gene repression with the efficiency and specificity of CRISPR in yeast is no longer a dream! In this episode of Genetics in your world, Dr. Ishikawa tells us about how he and colleagues adapted CRISPR interference for fission yeast, allowing controllable reversible and efficient transcriptional repression. Check out the paper,— “Implementation of dCas9-mediated CRISPRi in the fission yeast Schizosaccharomyces pombe,”—that was published in the February 2021 issue of G3. Hosted on Acast.

In this episode of Genetics in your world, we speak with Dr. Richard Gomulkiewicz about the evolution of gene drive resistance. With the discovery of CRISPR-Cas systems, scientists realized that they could engineer gene drives for a number of different applications. Using alleles with an “unfair” transmission advantage, we can design gene drives to help eradicate malaria vectors, agricultural pests, or even invasive species. Check out the paper, “Evading resistance to gene drives,”which was published in the February 2021 issue of GENETICS. Hosted on Acast. See acast.com/privacy for more information.
