Direct observation in the developing fly brain indicates that the response of a growth cone in a gradient of a guidance cue is adhesion to the source of the cue rather than attraction by the gradient.
The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.
Selective sweepstakes from pervasive positive selection, rather than demographic changes or random sweepstakes reproduction, is the primary determinant of reproductive skew and genetic diversity in the highly prolific Atlantic cod.

The accumulation of somatic mutations during aging is not uniform across tissue types and, in addition, shows significant variability in the source of mutation that can be modified by small molecule interventions.

In light of the mysteries underlying the biphonic nature of Tuvan throat song, information from multiple modalities is combined to explain how this remarkable phenomenon is achieved biomechanically.
The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.
Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.
Structural and biochemical analysis of full-length huntingtin protein illuminates the impact of the polyglutamine region on its structure and function.

Neotropical outstanding biodiversity emerged from sustained rates of species accumulation over time, although, for some periods, tetrapods were less successful than plants in keeping pace with a changing environment.
