Metabolomics data reveals unique metabolic insights into how cavefish adapt to nutrient limited environments while staying healthy.

Some deleterious mutations co-occurring within a genome can compensate each other, and this affects patterns of polymorphism, particularly in highly polymorphic species.

New morphological data of a primitive placoderm fish demonstrate both high regionalization of squamation and the bipartite histological structure of scale are plesiomorphic for jawed vertebrates.

A new ethologically relevant model for investigating the neurobiology of solitary, asocial behavior in the blind mole rat.

Salamanders originate as metamorphosed with a biphasic lifestyle as shown by the palate shape and several non-shape features associated with the vomerine teeth, with diverse ecological types displayed in living species achieved in the Early Cretaceous.

Genome editing in a close unicellular relative of animals suggests a premetazoan function of the Hippo pathway effector YAP/TAZ/Yorkie in the regulation of cytoskeletal dynamics and multicellular morphogenesis but not proliferation.

Archived histological material from tracing studies, immunohistochemistry, and Golgi impregnations allowed to discover a so far unrecognized structural difference, potentially of functional importance, between neocortical pyramidal neurons of rodent, carnivore, and ungulate as compared to monkey and man.

Pyramidal neurons with axons that exit from dendrites rather than the cell body itself are relatively common in non-primates, but rare in monkeys and humans.

The midbrain periaqueductal grey is a conserved mediator of elaborate courtship behavior in a range of vertebrate taxa, likely shaping how this behavior diversifies across the tree of life.

Rat blood profiles support non-linear aging with distinct trajectory shifts, and these profiles could be used to predict non-overt illness in rats or aging intervention efficacy.
