Repeated evolution of eye regression in subterranean mammals helps identify genes and regulatory elements involved in visual perception and development of the eye, and predicts candidate sequences with a potential role in ocular disorders.

Subterranean fossil bone hosts a living microbiome different from the surrounding sediment without evidence of original protein preservation.

Ancestral sequence reconstruction of an essential muscle protein involved in oxygen storage and transport accurately tracks secondary aquatic transitions in a speciose clade of insectivorous mammals.

Subterranean isopods endemic to regions with large igneous rock formations have a higher mutation rate and display an excess of mutations that are typical of an oxidative stress.

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

Multiple respiratory and vascular mechanisms have recurrently evolved across the vertebrates to alleviate the oxygen diffusion limitations inherent to the morphology of the retina.

Unlike all other mammals studied to date, the age-specific risk of mortality for naked mole-rats did not increase over decades of life, identifying this species as a non-aging mammal.

Astyanax mexicanus surface-dwelling fish exposed to complete darkness develop many traits resembling cavefish adaptations by phenotypic plasticity in a single generation.

Behavioral experiments reveal that ants, contrary to humans, avoid the formation of traffic jams at extreme density.

Before returning home, and when using novel routes, dogs align along the north-south axis, presumably to bring the mental map into register with the magnetic compass.
