Researchers created fully functioning mini brains using bioprinters.

When we think that AI cannot reach the same intelligence level as humans, we talk about binary-computer system-based AI. That AI is a very passive thing. But biological microchips where living neurons communicate with microprocessors are different things. Those systems are in mini-brains. Or cloned neurons that developed for medical testing. Those mini brains involve living neurons that interact similarly, to neurons in the human body.

"Scientists at the University of Wisconsin–Madison (UWM) say they have created the first 3D-printed brain organoids that function like natural brain tissue." (FreeThink, Scientists create the first “functional” 3D-printed mini brains)

“The neurons communicate, send signals, interact with each other through neurotransmitters, and even form proper networks with support cells that were added to the printed tissue,” said senior author Su-Chun Zhang." (FreeThink, Scientists create the first “functional” 3D-printed mini brains)

It's possible. That researchers can grow the mini-brains of the same size as human brains. That thing means that artificial brains can have the same intellectual level as human brains. In some science fiction tales the alien civilization is the computer center there are artificial brains under domes. Those brains will interact and control other systems remotely. And the life support system can feed those brains.

Printed tissues are tools that are bringing new ways to create treatments for accident victims. But printed tissues and especially printed mini brains create possibilities to create new types of morphing neural networks. In those systems. Living neurons live on the microchips and communicate with non-organic microchips. Those biological microprocessors can give the same intelligence to machines as humans have. When researchers connect those cloned neurons with the printed epidermis, that tissue can feed and deliver nutrients for those neurons.

"The researchers observed electrical activity in the electrode channels above the organoids, showing a reaction to the stimulus. (David Baillot/UC San Diego)" (ScienceAlert, The researchers observed electrical activity in the electrode channels above the organoids, showing a reaction to the stimulus. (David Baillot/UC San Diego))

Mini brains that transferred to mice gave the first reaction to the light. And that thing causes an idea that brain transplantation can be true sooner than we think.

Normally a brain transplant is extremely hard to make. The immune defense will destroy that transplant very soon. But making some large-scale genome transplants in the cell cultures, that thing makes it possible to transform a large number of cells into neurons. Researchers may take those cells from the receiver. Then they create a virus that changes those cells' genomes and turns them into neurons.

3D bioprinters make it possible to create real-life Frankenstein's monster.

Those systems can also be in the moving robots. Those robots are tools that the artificial brain can control using a microchip connection that is between the robot's body and brain tissue. If the 3D printer systems can create also other organoids and tissues. Theoretically, the system can print entire humans in the 3D printer system.

The intelligent artificial brain can be flat. Those neuron layers can be in a flat structure. Neurons are on the top. Then below the neurons is a structure that delivers nutrients for it. And then below that structure are microchips that communicate with axons. The life support system can be AI-controlled.

The thing is that the printers can also make full-scale brains quite easily. The simplest way is to connect those mini-brains to the network. More advanced 3D bioprinters can also create the same structures as human brains as those artificial brains. The electric system could upload data in the form of hard disks using synthetic neural signals to those neurons.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low. The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away. When the box is filled with quantum gas and som

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull. The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting armor has
