Nels and Vincent reveal how a motor protein in corn causes preferential transmission of chromosomes to egg cells, leading to non-Mendelian inheritance.
Nels and Vincent discuss the evolution of blood feeding to nonbiting in a mosquito, and evolution of bacterial virulence in the house finch caused by incomplete host immunity.
Sarah Tishkoff joins Nels and Vincent to explain work from her laboratory on the genetic basis of skin pigmentation in Africans.
Taking a cue from the recent frigid weather, Nels and Vincent explore how modifications of a neuronal cold-sensing channel regulate diminished cold sensitivity in hibernating mammals.
Vinny Lynch joins Nels and Vincent to discuss how a zombie gene in elephants protects these large, long lived animals from cancer.
Nels and Vincent reveal how the protein DHX9 suppresses RNA processing defects caused by invasion of the Alu retroelement into the human genome.
Maitreya Dunham joins Nels and Vincent to explain how her laboratory uses experimental evolution to study yeast flocculation, the community-building cell aggregation trait.
