A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.

Using different sets of input sequences to evolutionary reconstruction algorithms results in the exploration of many possible models, the intergration over which produces significantly more accurate models.

De novo formation of centromeres creates diverse karyotypes in flies and is accompanied by rapid turnover of centromere-associated satellite repeats.

Fog signaling with a narrow morphogenetic role in Drosophila has a deeply conserved function in epithelial morphogenesis across insects.

A new study upturns the long-held belief that in fruit flies, the yellow gene determines sex-specific behaviors by acting in the brain.

Melanization of a secondary sexual structure facilitates male mating success in Drosophila.

Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.

Sexual reproduction is responsible for the evolutionary success of selfish transposable elements.

Isoform-specific transcript localization underlies the evolutionary diversity of anterior axis determinants in embryos of dipteran insects.

Hairless emerged as an evolutionarily novel regulatory protein that replaced an ancestral paradigm of direct co-repressor recruitment by Suppressor of Hairless, its partner transcription factor in the Notch signaling pathway.
