Artificial selection on wing color and CRISPR/Cas9 knockout of the optix gene both alter scale lamina thickness in Junonia coenia, which shifts structural color wavelength and mimics macroevolutionary butterfly diversity.
People who have attempted suicide exhibit blunted sensory processing during breathing and pain perturbations, as well as lower heartbeat perception accuracy and reduced mid/posterior insula activity during interoceptive attention.
Variation in the gene NaMPK4 in plant populations increases reproductive yield, an effect which appears to be independent of soil water availability, neighbor-scale interactions and associations with arbuscular mycorrhizal fungi.
The mouse cerebellum regulates innate defensive neural circuitry by tonically controlling dopamine release in the periaqueductal gray, thereby modulating synaptic responses of the Chx10-positive neurons that generate freezing behavior.
Application of laser-capture microdissection to planarian intestinal tissue provides a new tool for analysis of tissue-specific gene expression in flatworms, and a new resource to advance investigations of gastrointestinal regeneration.
