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.
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 discuss a genomic analysis of the passenger pigeon, which shows that species with large and stable populations may be at risk of extinction after a sudden environmental change.
