The rat's stem cells are used to restore the mouse's brain. And that gives a new hope for brain injury patients. The ability to grow and clone stem cells limits those therapies. Genetic engineering makes it possible for that system can use genetically engineered rats to create new stem cells for humans. 

The ability to produce stem cells in the laboratory is the key element for successful stem cell therapies. Stem cells can be used to fix any tissue type, but the problem is where researchers can take the stem cells. One solution to that problem is cancer cells. The system can remove the genome from those cells. Then it must inject the new DNA into them. 

Making the new neurons from the stem cells is an interesting thing. The question is this: if we restore a mouse's brain using a rat's stem cells, does that mouse think that it's a rat? Or does it think that it's the mouse? 

The AI-controlled nanotechnology can map and create copies of any DNA. That allows the system to manipulate the DNA and inject it into the new cells. But the problem with neurons is this. When neurons are destroyed, the memories that they involve are gone. 

Genetically engineered cells allow to creation of cell cultures, that produce customized stem cells. Stem cells are the new and powerful tools for next-generation therapies. But the problem is that those stem cells must produce large numbers that can be the thing, that can make many other therapies old-fashion. 

The ability to regenerate brains and other tissues means that people are close to the thing, called immortality. Immortality requires that the person's body or some other thing replace the old DNA using new and fresh, young DNA. That allows that person can live a longer, and healthier life. DNA damage is a thing that causes aging. The nanotechnology can find the damaged bites from the DNA and replace that old DNA using nanorobots, that inject wanted DNA into those cells and mitochondria. This helps to keep the cells young. 

Nanotechnology allows to store the person's DNA in digital form. Then nanomachines rebuild that DNA structure. After that, the nanomachines replace the old DNA in the human cells and mitochondria. This is one step for new genome therapy. The system can remove old DNA from cells and then replace that old DNA.

The new 3D printers are coin-size systems.

"The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation. Credit: Sampson Wilcox, RLE" (Scitech, Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket)

Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems. 

There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that can produce large-size objects. 

The small-size 3D printers can installed on robot wagons or in small quadcopters. The ability to move on the ground and in the air makes those tiny robots create complicated 3D structures. The quadcopters that use 3D printers can print almost everything. The raw material can be metal wires that can be hung from a crane. And that material travels through printers. The printer can be below the crane and the raw material travels through the air. 

The idea is that the 3D printer system navigates using the precisely operating GPS. But it's also possible that there is a laser LED in those robots. The camera on the roof or on the drone that hovers above the working area follows the printers. The system requires 3 or 4 points that it can use the triangular measuring system to the precise location of the printers. 

The fact is this. Those small-size printers can fix damages on layers with very high accuracy. That kind of system can make anything. The raw materials are limited for the 3D-printed merchandise. And the miniature printers can make it possible to create new products and make repairments on the field. The miniature printers that are installed onboard ships can repair their damages.

Quantum technology requires new materials.

"Artist impression of new nanostrings that can vibrate for a very long time. These nanostrings vibrate more than 100,000 times per second. Because it’s difficult for energy to leak out, it also means environmental noise is hard to get in, making these some of the best sensors for room temperature environments.

One particular material group that interests researchers is "zero-dimensional material".  That term means materials with one atom layer. Or maybe someday researchers can make subatomic particle layers that are like graphene, but they form protons or neutrons. 

Researchers are interested in those lattice atom layers because 2D systems are easier to control than complex 3D structures. The 2D system involves fewer variables. AI can easily predict changes in 2D systems than in 3D complex structures.  

The zero-dimensional ferroelectric vortex: a quantum whirl that can act as a quantum spot in structure. Quantum dots can act as support points for quantum entanglement. That made between those points. This makes 2D materials more effective in quantum technology, than 3D structures. It's possible that in the 3D structure some atom moves, and that destroys the quantum dot. 

But they can make things like solar cells more effective. Quantum dots' purpose in solar cells is to put energy to move in the system. They create tension in the particles, and that makes it easier to put electricity move on the layer. 

2D materials are easy to control using lasers. The nano- or quantum fibers can act as ultimate sensors. The quantum fiber is the atom chain, that senses changes in the physical environment. 

The sensor itself is in the nanotube or hollow fiber. The laser ray sees how the sensor oscillates in the tube. The laser can adjust the sensor to the energy level so that it almost sends photons. When some outcoming effect hits that over-adjusted material, it sends extra energy to sensors. 

The quantum dots are like energy hills. The 2D ferroelectric vortex can pump energy into the atom tower in that vortex. This thing makes the new high-accurate quantum radar sensors possible. 

The quantum dots are like antennae. And they can see details, that regular radars cannot see. The vortex can transport energy into that atom tower. And it can create a small-size maser system. Those systems make it possible to break stealth technology.

Generative AI can turn SciFi into reality.

"Leading AI scientists warn of the significant risks associated with the rapid development of AI technologies in a Policy Forum. They propose that major technology firms and public funders dedicate at least one-third of their budgets to risk assessment and mitigation. They also advocate for stringent global standards to prevent AI misuse and emphasize the importance of proactive governance to steer AI development towards beneficial outcomes and avoid potential disasters.

Artificial general intelligence (AGI) can be the large language model, that can create smaller specific language models. And maybe the computer or programming industry works around large-scale language models. The clients use the AGI to generate those limited AIs. 

The idea is that the customers pay to owners of the AGI for things like server maintenance. The owners of the AGI need money for electric bills. This is one of the reasons why researchers are working on things like geothermal and solar panels for green energy production for server halls. If server halls use green energy, they don't pollute. 

And maybe the question,  what the employer hears at the magistrate when they register a company is "Have you downloaded your own AI yet"? 

And then they can download the limited "baby AI" to their servers. The limited AIs are modules that can be created to handle larger-scale and more complex data structures. 

The main problem is that people like Chinese intelligence can use those limited AIs as modules that they can use to create their own AGI. The intelligence just creates multiple companies and then downloads the limited AIs to those companies. Then those limited AIs can act as modules for complicated data structures. 

The machine as intelligent as the human waits for ten years. This is one prediction for the future. When somebody would tell me that someday we can make that thing, I would say that this kind of AI needs so many databases that it's too hard to complete. But today generative AI can make those 100-200 billion databases, if it has space, where it puts that structure. 

The intelligent machines are frightening. Somebody resists them, but they are coming. One of the reasons why somebody resists those systems is that they take jobs from humans. The problem is that. This thing like unemployment interests people only when the AI takes their jobs. When the U.S. car industry took jobs to Mexico, nobody was interested. That thing caused unemployment and social problems. But the police were enough to handle that problem. The media is interesting only when the AI takes jobs from reporters. 

The AI can make life easier. It can make working days easier. And it leaves time for innovation. But unfortunately, AI is the tool, that allows to fire half of workers. And that is the problem. The company leaders don't see AI as a chance to be more generative and more innovative. They see it as a chance to decrease the costs and crew. That is one problem with companies. 

The companies like Space X are very innovative. They know how to benefit from the publicity that rocket engineering brings to them. And that is a good thing for Elon Musk's business. The reason why Space X detonates rockets in front of people's eyes is that: these kinds of things are interesting. And interesting things bring publicity. And maybe some companies will come to buy a launch from Space X when they see that work. 

That thing causes one problem. The space industry, and especially the space launch industry accumulates into the hands of companies like Space X. The Pentagon made contracts with Space X and Starlink about their communication, location, and other systems. That thing gives very much power into the private hands. That means the private companies will get the military forces' communication in their hands. 

That means the world is decaying. There are innovative companies that make many new things. That innovation brings big profits for companies that own the patents. And then there are non-innovative companies that pay for those innovative companies about their products. That thing makes Space X and those kinds of innovative actors more and more powerful. 

Generative AI is a tool that can revolutionize engineering. In the production stage, the engineers must only give the requirement specification to the computer. Then the AI selects raw materials. And then it can start to create the product. The industrial robots can have 3D printing systems in their body. And that makes those systems more flexible than we ever imagined. 

The system can follow the data flow that comes from the rockets. And by analyzing that data the system knows if there is a problem in a certain engine. If a rocket uses many small engines the system can shut down one or two engines, if there are failures. In that process, the system just cuts the fuel and oxygenize from the engine. 

In the case of an emergency, the system can just separate the upper stage. And try to bring the payload safely to the ground. That can happen using a parachute or if the upper stage can land vertically that thing can bring the payload safely to the ground.

Biotechnology gives unlimited possibilities.

"Between day one (left) and day 14 (right), plant cells 3D printed in hydrogel grow and begin flourishing into yellow clusters. Credit: Adapted from ACS Central Science 2024, DOI: 10.1021/acscentsci.4c00338" (ScitechDaily, Crafting Programmable Living Materials With Synthetic Biology & 3D Printing)

The synthetic DNA-manipulated biomaterials revolutionized 3D printing technology. The ability to combine species makes it possible to create large-size biological structures. That follows certain shapes. But when that technology is connected with 3D printing technology, that makes the ultimate tool. The DNA-manipulated cells can create the LEGO bricks that the 3D printers can put in certain places. The ability to connect corals and starfishes makes it possible to create the structures, that the bioprinter can put in certain places. 

The silicon algae's shell genome can connected with the trees. And that can create trees with silicon shells. Genomes from electric eels can turn vegetables into energy producers. Energy trees are the tools that can solve the part of climate change. 

The ability to connect spider's silk genomes to cotton and hemp turns their fibers into the spider's silk. Make the revolution in the protective clothes. The genetically engineered bacteria can also create oil. That chemists can use to create synthetic materials. And without climate change, those genetically engineered bacteria can create gasoline by using bacteria cultures. 

Some ideas in oil refinery platform's tanks will put the bacteria that turn the biomass into oil in the anaerobic environment. Then the system pumps carbon dioxide to those chambers that make bacteria create the oil. This process is not a very good idea. In the time of climate change. 

Genetic engineering makes it possible to create a large mass of things like antibiotics and other medicals. The possibility to manipulate DNA gives unlimited opportunities for R&D workers to create things. Like cells that create electricity. Electric eels can give 600-850 volt electric impulses, and those cells can used as power sources for robots. 

The biological power source is a good replacement for fuel cells in small-size, low-power systems. The biological batteries need only nutrients. And if those cells are connected with vegetable cells. That makes it possible to use the nutrients that are created for plants. These kinds of systems are the fundamental tools in mobile technology.

The 6G communication can use terahertz radiation.

"Tohoku University researchers have developed a tunable filter for terahertz wave signals, facilitating higher transmission rates and improved signal quality. This breakthrough, crucial for the advancement of terahertz applications in communication, medical imaging, and industrial analysis, promises to unlock the full potential of terahertz waves across various fields." (ScitechDaily, Unlocking the Future of 6G: A New Breakthrough in Terahertz Communication)

The world is going to be mobile. And that means there is always a need for new and faster mobile networks. The problem with data networks is that even if 4G and 5G are fast. Mobile applications always turn harder and harder. More and more mobile applications like cell phones connect to mobile networks. And that thing increases the need for data transportation capacity. 

In the future, all TV sets and even houses use wireless data transmission because data cables are expensive. It's cheaper and easier to install long-range wireless mobile hotspots than to install optical cables to the house. And the next-generation data communication solution can be a Starlink-based satellite solution. 

"Schematic concept of the developed tunable filter. (a) Cross-sectional view of the filter; (b) relationship between period and refractive index; (c) frequency shift due to the change of refractive index. Credit: Ying Huang et al." (ScitechDaily, Unlocking the Future of 6G: A New Breakthrough in Terahertz Communication)

The ability to filter terahertz radiation means that the next-generation data communication networks might use terahertz radiation for data transmission. The biggest problem with using terahertz radiation has been filtering that radiation. The problem is how to make data transmission between multiple mobile systems using the same frequency is solved. 

The system equips every data package with the identifier. That allows the router to route those data packages into a certain device. And other ways that identifier makes the receiver reject those data bites. After that, the device collects those data bites into one entirety. 

The ability to put a serial number to those data bites makes the network more flexible and more secure. The system can use different routes to send the package and the serial number allows the receiver to collect data in its entirety even if the system uses radio- and optical communication at the same time. 

"The mechanically refractive index variable metamaterial. Credit: Ying Huang et al." (ScitechDaily, Unlocking the Future of 6G: A New Breakthrough in Terahertz Communication)

In that model missing serial number tells the system that there are missing data bites. And the transmitter can send those missing bites again. That saves the network and releases its capacity for something else. 

But the other thing is how to protect data against physical damage. When two electromagnetic fields with different frequencies impact those fields start to disturb each other. That thing is problematic because the system must remove the artifact, the non-controlled part from it. If some outcoming waves hit electromagnetic fields, they act like a jammer system. Those outcoming waves destroy the data from the field. 

There is one problem with radio communication. The problem is that there is a limited number of radio frequencies. And terahertz radiation helps that problem by offering new frequencies for communication systems. The terahertz radiation is a new frequnéncy for communication. And the terahertz networks can be the solution for the next-generation data transmissions.

Quantum networks can make the world more secure.

"The 100-kilometer fiber optic cable through which a team of researchers at DTU has successfully distributed a quantum-encrypted key securely. Credit: DTU" (ScitechDaily, An Unprecedented 100 km – Researchers Set New Distance Record With Quantum Keys) 

Researchers made new records. They exchange quantum keys securely within 100 km. And that is the next step for ultra-secured data transmission. The networks are unable to operate if they are not secured. The cornerstone for secure communication is that the systems can exchange keys securely. 

The neurocomputer requires ultra-secure communication. 

The new findings are a big advantage to developing quantum networks. 

The difference between quantum networks and regular networks is that in quantum networks, information travels in qubits. The quantum network's problem is that the system packs information in the physical object. And that makes quantum computers resistant to regular eavesdropping. 

However, the quantum computer is vulnerable to outside effects. In quantum networks, information travels in quantum channels like nanotubes or hollow laser rays. When the quantum network sends information over long distances. It creates the quantum channel using phonon- or acoustic lasers to make the hollow channel through air. Then the system shoots hollow laser rays through it. And qubit can travel through that channel. 

The quantum network is not a synonym for a quantum computer. The quantum computers use quantum networks in their processors. However, the quantum network can transmit information between binary computers, as well as, the quantum network transports information between quantum computers.

Credit: Institute of Industrial Science, The University of Tokyo" (ScitecchDaily, Redefining Quantum Communication: Researchers Have Solved a Foundational Problem in Transmitting Quantum Information)

There are three main types of quantum networks. 

1) All quantum networks. Those systems transport all data in quantum mode. 

2) Hybrid quantum networks. Those networks send only encryption keys in qubits. The rest of the data travels in the form of regular electromagnetic signals. 

3) Virtual quantum networks. Those networks share data in multiple frequencies or multiple lines. The system shares information with multiple transportation lines using TCP/IP. Then it sends information at the same time. In this system, all data pack has a serial number. 

And that helps the receiving system to sort those received data packets into the right order without depending on their arrival order. So the system can mix those data packets into arbitrary order before sending them. Then receiving system can put them into the right order using those serial numbers. 

The quantum network allows ultra-secured communication between computers. And also another ultimate computing system called neurocomputer requires ultra-secured communication. In neurocomputers, the processor units can be at long distances from each other. 

Networked workstations can also act as neurocomputers. Theoretically is possible to transform the entire internet into a giant neurocomputer. The technical platform exists, but a lack of political willingness denies that kind of project. 

The quantum computer is a non-centralized data-handling tool. That system is multiple networked microprocessors. Just like quantum computers neurcomputer can drive multiple operations at the same time. The speed of those operations is not the same as quantum computers. But binary computers are less vulnerable to outside anomalies than quantum computers. 

The neurocomputer is not a synonym for neural networks. The neural network is the thing that interconnects sensors with computers. So a neural network is a sensory system the network that connects things like surveillance cameras with neurocomputers.
