Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.
Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.
The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.
The earliest fossil evidence of a mimetic relationship between the Jurassic moth lacewing Lichenipolystoechotes and its co-occurring fossil lichen Daohugouthallus predates modern lichen-insect associations by 165 million years.
Structure modeling, site-directed mutagenesis, and current recordings revealed the mechanism by which stabilization of voltage sensors in the resting and activated states determines the gating properties of the CaV1.1 calcium channel.
Irreversible differentiation into somatic cells is evolutionarily optimal if changing cell phenotype is costly, a few somatic cells already improve the organism's performance, and the organism is large enough.
