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.
Researchers have identified urban sewage as a critical hotspot for the evolution and spread of drug-resistant bacteria, highlighting an urgent need for nationwide wastewater monitoring to prevent future health crises.
