Friday Squid Blogging: Squid Can Edit Their Own Genomes

This is new news:

Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edit their own genetic instructions not only within the nucleus of their neurons, but also within the axon -- the long, slender neural projections that transmit electrical impulses to other neurons. This is the first time that edits to genetic information have been observed outside of the nucleus of an animal cell.

[...]

The discovery provides another jolt to the central dogma of molecular biology, which states that genetic information is passed faithfully from DNA to messenger RNA to the synthesis of proteins. In 2015, Rosenthal and colleagues discovered that squid "edit" their messenger RNA instructions to an extraordinary degree -- orders of magnitude more than humans do -- allowing them to fine-tune the type of proteins that will be produced in the nervous system.

Friday Squid Blogging: Jurassic Squid Attack

It's the oldest squid attack on record:

An ancient squid-like creature with 10 arms covered in hooks had just crushed the skull of its prey in a vicious attack when disaster struck, killing both predator and prey, according to a Jurassic period fossil of the duo found on the southern coast of England.

This 200 million-year-old fossil was originally discovered in the 19th century, but a new analysis reveals that it's the oldest known example of a coleoid, or a class of cephalopods that includes octopuses, squid and cuttlefish, attacking prey.
