Timely regulation of growth cone dynamics, including filopodial and cytoskeletal rearrangements through phosphorylation signals from glial cells, shapes the photoreceptor axon targeting.

Timing in the formation of neurons influences synaptic connectivity.

Large-scale screens and computational approaches reveal phenotypes for 3492 genes and gene-ontology predictions for 783 genes, including hitherto unstudied genes, which provides a potent platform to further dissect protein function.

Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

Pervasive ‘futile cycling’ by chromatin-modifying factors suggests a mechanism for creating new links in gene regulatory networks.
