The great intelligence of the octopus and its similarity to the human brain



The great intelligence of the octopus and its similarity to the human brain
The molecular basis of octopus cognitive abilities continues to be studied.

Octopus is an exceptional organism with an extremely complex brain and unique cognitive abilities among invertebrates.

No, it’s kind of an animal has more in common with vertebrateshowever, the evolutionary cause of his intelligence and the molecular mechanisms that determine it are still under study.

new studypublished in a magazine BMK Biologyshows that The neural and cognitive complexity of the octopus can be traced back to a molecular analogy with the human brain..

The work is the result of a collaboration between International Higher School of Advanced Studies (CISSA), Trieste, and Anton Dorn Zoological Station of Naples (SZN) that Italian Institute of Technology (dark side) Genoa.

Chava: “jumping genes(jumping genes)

The sequencing of the human genome showed in 2001 that over 45% of it is made up of sequences called transpositions.. Known as ‘jumping genes‘, are DNA sequences that can move from one point of the genome to another: using the molecular mechanisms of “copy and paste” or “cut and paste” they can be duplicated or mixed.

In most cases, these moving elements are idle. Sometimes because over generations, they accumulated mutations that deprived them of the ability to movesometimes because, although their sequence is not broken, the cell uses defense mechanisms that block them and make it impossible for them to move.

“It was already known that the octopus genome is rich in transposons, but a potentially active element in these animals has never been found.”
Remo Sanges, director of the SISSA Computational Genomics Laboratory.

The investigation shows that the same “jumping genes” are active both in the human brain and in the same organ of two species of this invertebrate: common octopuscommon octopus and Octopus bimaculoidesoctopus from California. According to experts, this discovery may help to understand the secret of the intelligence of these amazing organisms.

Your relationship with memory

Among the various types of transpositions that exist, the most represented in the human genome are those that belong to a family called LINE, inclusions of long nuclear elements (de Long intermittent nuclear elements).

Traditionally, LINE’s activity has been considered a relic of the past, a legacy of the evolutionary processes in which these moving elements participated. But in recent years, new evidence has emerged showing that LINE activity in the human brain is finely regulated.

actually they especially active in the hippocampus, the most important structure of our brain for neural control of learning processes. This evidence has led many scholars to believe that they associated with cognitive abilities such as memory.

important conclusion

The discovery was made possible by modern sequencing techniques, which made it possible to analyze the molecular composition of active transpositions in the nervous system of the octopus.

According to Giovanna Bridge from the zoological station of Anton Dorn, the vertical lobe is a brain structure that, in the octopus, is the seat of learning and cognitive well as the human hippocampus.

octopus intelligence
Octopuses are very good at different types of complex learning, but their level of intelligence is hard to measure.

Octopuses and humans are the only organisms in which the expression of LINE elements has been observed in the lobes of the brain. that control cognitive abilities.

The octopus brain in many of its features is functionally similar to the brain of mammals.

Second Stefano Gustinicfrom the Italian Institute of Technology, and Giuseppe Petrosinofrom the zoological station of Anton Dorn, this The similarity between man and octopus, which shows the activity of the LINE element in the origin of cognitive abilities, can be explained as a fascinating example of convergent evolution.the phenomenon in which two genetically distant species develop the same molecular process independently in response to similar needs.

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet



NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

My power is very low, so this might be the last photo I can upload. But don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will, but I’ll sign here soon. Thank you for staying with me.

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.

What’s new on February 7, 2023



OnePlus 11 5G Buds Pro 2 evento

Being very close companies, OPPO and OnePlus have decided to create a new partnership, with the latter being a pioneer in the market. It has become the representative of the best smartphones in the group, and this will be seen very soon.

Proving this, OnePlus has announced that it will have news soon. The following brand assets will be announced on February 7, 2023. We are talking about OnePlus 11 5G and Buds Pro 2.
