A mysterious squid-like cosmic cloud, this nebula is very faint, but also very large in planet Earth’s sky. In the image, composed with 30 hours of narrowband image data, it spans nearly three full moons toward the royal constellation Cepheus. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula’s bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a more recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, the cosmic squid would represent a spectacular outflow of material driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, this truly giant squid nebula would physically be over 50 light-years across.

This is just crazy:
Scientists don’t yet know for sure why octopuses, and other shell-less cephalopods including squid and cuttlefish, are such prolific editors. Researchers are debating whether this form of genetic editing gave cephalopods an evolutionary leg (or tentacle) up or whether the editing is just a sometimes useful accident. Scientists are also probing what consequences the RNA alterations may have under various conditions.
I sometimes think that cephalopods are aliens that crash-landed on this planet eons ago.

It’s a Taningia danae:
Their arms are lined with two rows of sharp retractable hooks. And, like most deep-sea squid, they are adorned with light organs called photophores. They have some on the underside of their mantle. There are more facing upward, near one of their eyes. But it’s the photophores at the tip of two stubby arms that are truly unique. The size and shape of lemons—each nestled within a retractable lid like an eyeball in a socket—they are by far the largest photophores known to science.

A Peruvian oversight law has the opposite effect:
Peru in 2020 began requiring any foreign fishing boat entering its ports to use a vessel monitoring system allowing its activities to be tracked in real time 24 hours a day. The equipment, which tracks a vessel’s geographic position and fishing activity through a proprietary satellite communication system, sought to provide authorities with visibility into several hundred Chinese squid vessels that every year amass off the west coast of South America.
[…]
Instead of increasing oversight, the new Peruvian regulations appear to have driven Chinese ships away from the country’s ports—and kept crews made up of impoverished Filipinos and Indonesians at sea for longer periods, exposing them to abuse, according to new research published by Peruvian fishing consultancy Artisonal.
Two things to note here. One is that the Peruvian law was easy to hack, which China promptly did. The second is that no nation-state has the proper regulatory footprint to manage the world’s oceans. These are global issues, and need global solutions. Of course, our current society is terrible at global solutions—to anything.
