A Drosophila olfactory circuit exhibits experience-dependent glial pruning during a well-defined critical period, with long-term consequences for odor processing.

A new collection of driver lines enables experimental manipulation of over 300 cell types centered around the mushroom body in Drosophila.

Tgfbr1 signaling governs all processes associated with the trunk to tail transition, including the repositioning of neuro-mesodermal progenitors, as well as the remodeling of the lateral plate mesoderm and embryonic endoderm.
