Octopuses Know What Time it Is

It’s time for Gene-Editing!

An octopus questions the findings at Tel Aviv University.

From theAtlantic:

Octopuses have three hearts, parrot-like beaks, venomous bites, and eight semi-autonomous arms that can taste the world. They squirt ink, contort through the tiniest of spaces, and melt into the world by changing both color and texture. They are incredibly intelligent, capable of wielding tools, solving problems, and sabotaging equipment. As Sy Montgomery once wrote, “no sci-fi alien is so startlingly strange” as an octopus. But their disarming otherness doesn’t end with their bodies. Their genes are also really weird.

A team of scientists led by Joshua Rosenthal at the Marine Biological Laboratory and Eli Eisenberg at Tel Aviv University have shown that octopuses and their relatives—the cephalopods—practice a type of genetic alteration called RNA editing that’s very rare in the rest of the animal kingdom. They use it to fine-tune the information encoded by their genes without altering the genes themselves. And they do so extensively, to a far greater degree than any other animal group.

Scales of History

13 and 20 and 20 and 20.

Ah, theAbysmal Days, when apparently we Leap over theAbyss and my mind overflows with thoughts on the higher functions of how the way in which we view or perceive time affects the way we think. It changes our mind. Between what I’ve researched astronomy, chronobiology, body function by time of day, time of month, time of year, time of life, embodied cognition, neurobiology, story, symbol, imagination, creativity, history, and reaching back to anthropology as well as calendar systems themselves in order to come up with this. It isn’t idle chatter. It’s the result of my subconscious knitting it all together in the background, and as  has become habit, at the New Year, it presents itself for consideration.

In this case, it’s the shape of history, or at the very least longer measures of time. 260 seems to be at the heart of it. 13 is one sacred number to the Maya, the other is 20, which is multiplied much like we do with 10 in observing decades, centuries, millennia. I also noted that the 13 is often associated with the major articulations of the body (ankles, knees, hips, wrists, elbows, shoulders, neck), 20 is associated with the fingers and toes.

Ancestors and Relatives

Genealogy, Identity and Community

Ancestors & Relatives by Eviatar Zerubavel

Chapter 1 – the Genealogical Imagination

p6
…given the long history of human migrations, we often feel nostalgic about the long-lost time “when place, identity, culture and ancestry coincided.” “Standing on the land that ancestors knew” can thus

produc[e] a sense of genealogical connection that is sometimes explained … as an inexpressible sense of spiritual affinity, and often experienced bodily in “shivers down the spine” and “goose-bumps”… [It] is often imagined as a shared physical experience that links ancestors to their descendants across time
