Cross-species alignment based on cortical myelin content can dissociate cortical expansion and relocation from changes in connectivity profiles in the temporal lobe of higher primates.
Computational models and software connect metagenomics to metabolic network reconstruction, assess metabolic complementarity between species, and identify critical species associated to functions of interest.
Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.
Genetic incompatibilities are common and widely distributed throughout the genomes of swordtail fish, and prevent the regions of the genome around them from being exchanged between different species.
Data analysis of a large number of species indicates that a negative temperature-mass relationship is not common among species, which has been an ecological assumption for over a century.
Shigella flexneri, globally the most frequent cause of bacterial dysentery, is far more diverse, and has caused disease around the world for far longer than other Shigella species by persisting in local environments over extended timescales.
Combinatorial transcription factor binding shared by multiple species enriches for essential biological pathways and coincides with disease-causing regulatory DNA mutations.
Re-characterization of the targets of a commonly used nuclear speckle marker unexpectedly leads to the discovery of the elusive core of the nuclear speckles.
Humans and other animals have different strategies for extracting the pitch of sounds, potentially driven by the species-specific frequency selectivity of the ear.
