What The First Genetically Modified Squid Mean To Science: Shortwave: NPR



On the left is a longfinned squid that lives on the unchanged shore (Doryteuthis pealeii). The person on the right is injected with CRISPR-Cas9 aimed at a pigment gene before dividing the first cell. It has very few pigmented cells and brighter eyes.

Until recently, cephalopod research was hampered by the fact that there was no way to control the genes of squid or octopus. But all that changed with the first transgenic squid. Nell’s Nell Greenfieldboyce explains how to make this breakthrough at the Marine Biology Laboratory and why it is a game-changing tool for scientists studying these organisms.

Read Nell’s story here and see more of her reports on cephalopods here and here.
