Several interacting molecular and biochemical processes are vital to establishing cell polarity. In a recent study, researchers at the Indian Institute of Science, Bengaluru, studied some of these signals in the centrosome—an organelle in the cell responsible for cellular organisation—of a single-cell embryo.
Coastal erosion and the proliferation of seawalls, exacerbated by climate change and human activity, are rapidly eliminating critical nesting habitats for sea turtles along the Karnataka coast.
