Octopuses and squid are masters of RNA editing while leaving DNA intact
Modifications to RNA could explain the intelligence and flexibility of shell-less cephalopods.

RNA editing helps octopuses cope with the cold
California two-spot octopuses tweak the proteins they make, potentially to help maintain brain function when temperatures dip.
- Animals
Octopus, squid and cuttlefish arms evolved to ‘taste’ different compounds
Octopus suckers can taste a variety of greasy, sticky molecules, while squid and cuttlefish suckers detect bitter compounds.

Squid edit their RNA to keep cellular supply lines moving in the cold
Squid change their RNA more often in the cold, producing motor proteins that keep cellular cargo on track.

Invisible comet tails of mucus slow sinking flakes of ‘marine snow’
New measurements reveal the gunk that surrounds the particles, an important factor in understanding how the ocean sequesters carbon.
- Animals
Scientists have now recorded brain waves from freely moving octopuses
The data reveal some unexpected patterns, though it’s too early to know how octopus brains control the animals’ behavior, a new study finds.

The animal kingdom never ceases to amaze
Editor in chief Nancy Shute revels in the wonder of animals, from psychedelic toads to extinct pterosaurs.
- Paleontology
Vampire squid are gentle blobs. But this ancestor was a fierce hunter
New fossil analyses of 164-million-year-old ancestors of today’s vampire squid show the ancient cephalopods had muscular bodies and powerful suckers.

Scientists are arguing over the identity of a fossilized 10-armed creature
An ancient cephalopod fossil may be the oldest ancestor of octopuses, but the interpretation hinges on the identification of one feature.
- Paleontology
This bizarre ancient critter has been kicked out of a group that includes humans
A wee sea creature without an anus was thought to be the oldest deuterostome. New imaging showing it had spines led to its reclassification.

This octopus-inspired glove helps humans grip slippery objects
The human hand, for all its deftness, is not great at grasping slippery stuff. A new glove aims to change that.
