Genetic conflicts between sex chromosomes during spermatogenesis may drive the rapid evolution, function, and turnover of some sperm nuclear basic proteins in Drosophila species.
Cancer cells driven by mutations in KRAS or EGFR are dependent on DUSP6 to prevent ERK-induced cell death, creating a novel vulnerability for targeted therapy.

Changing which layer 6 neurons are active during sensory tasks disrupts the detection and encoding of changes, but still allows integration of sensory information in the absence of changes.
In the processing of spoken narratives, bottom-up acoustic cues and top-down linguistic knowledge separately contribute to neural construction of linguistic units.

Recordings from the mouse brain as animals learn a lever pressing task reveal how the motor system optimizes skill learning by reducing variability in those aspects of task performance that are essential for achieving a goal.
