Can We Reconstruct Evolution's Hidden History?—A Conversation with Colin LaMont
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. Read his paper titled, "Optimal control and the dynamics of ancestral lineages," published in the August 2026 issue of GENETICS: https://doi.org/10.1093/genetics/iyag122

Mapping Whole-organism Genetic Comorbidities Across Model Species Using Unified Ontologies—A Conversation with Caitlin Peaslee
In this episode of Genetics in Your World, GSA Early Career Scientists Multimedia Subcommittee member Luke Arnce interviews Caitlin Peaslee of the Center for Embryonic Cell and Gene Therapy at Oregon Health and Science University about her research. Read her paper titled, "Mapping whole-organism genetic comorbidities across model species using unified ontologies," published in the April 2026 issue of GENETICS: https://doi.org/10.1093/genetics/iyag038 (https://doi.org/10.1093/genetics/iyag038)
This study developed a cross-species computational framework, CoMo DBM, to analyze 204 mouse genes that caused non-obstructive azoospermia and mapped their phenotype associations across human, zebrafish, fruit fly, and roundworm databases.
