What does the first genetically modified squid mean for science: Shortwave: NPR



To the left is an unchanged attraction of a long squid on the ground (Doryteuthis pealeii). He on the right was injected with CRISPR-Cas9 targeting a pigmentation gene before the first cell division. There are very few pigmented cells and lighter eyes.

Until recently, cephalopod research has been hampered by the fact that there is no way to manipulate squid or octopus genes. But everything has changed with the first genetically modified squid. NPR Nell Greenfieldboyce explains how this breakthrough was made at the Marine Biological Laboratory and why it is a game changer for scientists studying these criteria.

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