Nels and Vincent reveal that female-specific DNA associated with sex in strawberries has repeatedly changed its genomic location, possibly linking new genes with sex.
Nels and Vincent discuss how the loss of an enzyme in marine mammals millions of years ago now makes them at risk for neurotoxicity caused by human-made organophosphorous pesticides.
Nels and Vincent are astounded by the finding of an insect-derived virus in a fungus that manipulates the behavior of flies.
Matt joins Nels and Vincent to discuss the neutral theory of evolution and its rejection in light of genome-scale data.
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 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.
