Early-life exposure to conspecific urine and bedding extends the lifespan of female mice, indicating that social chemosensory cues can influence aging in a mammal.
The eggshells of palaeognath birds (e.g. ostrich, moa, kiwi, emu) have diverse homology and convergent features, and are useful modern analogues for the evolution of non-avian dinosaur eggshells.
Infants' vocalisations are contingent on their own stress physiology, and alter the inter-personal dynamics of how stress states are shared across the infant-caregiver dyad.
In bacteria, frequent adaptive copy-number mutations can hinder the fixation of beneficial point mutations and hence the divergence of duplicated DNA sequences.
Studying the genomes of mammals with sparse hair covering identifies specific genes and regulatory regions responsible for the formation of hair and skin, some of which were previously unrecognized.
An approach that allows scientists to identify regions of the genome that evolved faster in hairless mammals reveals candidate genetic mechanisms that gave rise to hairlessness.
The comparison of three ciliate species that share complex pathways for natural genome editing allows capture of intermediate states in the acquisition of scrambled genes and elucidating a pathway for the origin and evolution of extremely rearranged chromosomes.
