There is quite simple math behind the two-stage encryption.



When we log in to some internet services. We see the famous screen, and there are two lines. The upper line is the normal login. Where we write things like Email or username. That username is called a public key.  The fact is that the username is also non-public. That means that is hidden from other users.  

Below that line is the space for the password.  That is called a "hidden" or non-public key. In that kind of encryption. The user first logs in to the system using the public key. That tells the system that the user has the right to use the system. 

Then the passphrase is the key to the step in the system. This is the key procedure in modern cryptology or encryption process. When the system wants to encrypt information. The system first sends the information who is the sender. Then that system encrypts data and sends it to the receiver. And if the receiver has the right key, that thing allows the receiver to open the message. 

Encryption allows the receiving system to select the information that it uses. That thing makes it possible to transmit information by using the same frequency to multiple receivers. And without that public key. The system cannot find the right receiver from the network. In the network, routers and switches use the public ID to route the message to the right address.

In the RSA encryption process. The system uses long binary- and quantum binary decimal numbers to secure information. The thing that secures information is the selected binary numbers. The formulas that the system uses are always the same. There can be different formulas or calculation series in the encryption process. But the process itself is similar all the time. 

The weakness of that encryption is this. The receiving system must know the formula and binary numbers that the transmitting system sends. The public key requires that the receiver knows what algorithm or formula it must use in the decryption process. And then another thing is that the receiving system must know the binary numbers. That transmitter is used in encryption.

And why do those systems require binary numbers?  It's possible to divide The binary number by using only that number itself. That denies the ability to use other numbers. Then the binary number itself opens the message. The problem is that the user must set the right and the same binary numbers to the transmitting and binary systems. 

The encryption process is based on the ASCII codes. The encryption system multiplicates and divisions those codes by using binary numbers. The system can make multiple divisions and multiplications. The receiving system must make those calculations backward so that it can open the message. The math behind the encryption is very simple. 

It contains divisions, multiplications, and maybe plus-minus calculations. That makes it very simple and effective. The problem is that this type of encryption is old-fashioned. That encryption was made in the late 70's and the short algorithms are a piece of cake for the fast, high-speed supercomputers. Quantum computers can make the code braking in seconds, even if the binary computers generate those numbers for years.

Scientists injected young mice's blood into old mice, and that blood rejuvenated them.


 Scientists injected young mice's blood into old mice, and that blood rejuvenated them.


That thing causes interesting visions about the possibility of creating something that slows aging. Before that test, researchers injected young mice with brain fluid.

Normally, we think that this kind of thing is hard to make. Our immune system destroys that blood immediately. But then we can think about the possibility of creating artificial or cloned bone marrow cells, and we can say that this kind of thing removes immune reactions.

Groundbreaking research where researchers can reprogram cells into stem cells can make it possible for scientists to rejuvenate an individual's bone marrow cells, making those observations even more fundamental than we think. The ability to create stem cells and turn them into bone marrow cells makes it possible to make bone marrow transfers to individuals by using their cells.

And the ability to use the receiver's cells makes this thing fundamental. Researchers can create Those new bone marrow cells by using artificial or reprogrammed stem cells.





Clones are also the same organism as the elder ones. And in that case. Researchers can clone cell groups or entire individuals. And if the only thing required is blood, that can be produced in cell cultures.

That thing causes interesting visions. In some visions. Researchers will clone the old mouse. And then researchers will inject the younger clone's blood into the old individual. Another version is that the crew takes the bone marrow from the fetus.

Then cryogenic system freezes that bone marrow in a cryogenic laboratory. When individuals turn old researcher injects the blood that those frozen bone marrow cells create into those old individuals. Another version is that those young bone marrow cells will be cloned. And then those young cells will be injected into the elder individual. Because those cells are the receiver's own, there should be no complications.

How do the mice have a connection with humans? Mice are growing extremely fast. That thing makes them suitable for research work. By using modern nanotechnology is possible to make pigs and mice produce tissues that fit humans. In those models, the tissues of pigs and mice will turn to create things like blood or skin, that fit individual humans. The system manipulates the DNA and reprograms cells so that they create proteins that fit the receiver.

Genetic manipulation makes it possible to create things like customized bone marrow. The idea is that the cells will reprogram to stem cells that form bone marrow. And if those DNA sequences are taken from the receiver. That thing makes it possible to get bone marrow that fits the receiver because those cells are the receiver's own. Polymerase chain reaction allows to make multiple copies from the stem cell's DNA. The idea is that one cell will reprogram into a stem cell. And then PCR multiplies its DNA. And then, the system replaces some other cell's DNA by using that stem cell's DNA.

Memory manipulation can be a tool. That removes bad memories.

But who makes the decision? What are bad memories?  The ability to select memories. It is a new thing. For. Psychotherapy. But those things ...
