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.
Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.
A domain-general structure learning mechanism, supported by anterior insula, moves beyond explicit category labels and dyadic similarity as the sole inputs to social group representations and predicts ally-choice behavior.
Protein IGFBP-4 acts as a genotoxic stress mediator that, entering into circulation after its secretion by senescent cells, could promote further senescence phenomena in non-injured cells thus impairing tissues’ homeostasis.
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.
