Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.

Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.

Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

The Notch signaling pathway has a central role in the formation of the circuit that controls egg-laying in the nematode worm C. elegans.

The Notch signaling pathway has a central role in the development of the nervous system, and also in the establishment of networks of connections in the adult brain

An interaction between two proteins enables the spindle—the structure that segregates chromosome pairs during mitosis—to change size as cells divide.
