INGRID LEKK, WILSON LABORATORY, UNIVERSITY COLLEGE LONDONTo study the zebrafish nervous system, scientists used a combination of CRISPR-Cas9 gene-editing technology and crossbreeding to highlight genes they're interested in. In this case, researchers labeled a gene expressed in neuromast cells that reside within the lens of the eye. Neuromasts are part of a mechanosensory system in fish that is responsive to surrounding movements in the water and is crucial for a range of behaviors such as avoiding predators and schooling.
