The DNA and its many functions in technology




The DNA and its many functions in technology

This is the writing of the futuristic visions of the thing, what is called nanotechnology. The nanotechnology allows many things, what is been impossible before. And we can make many futuristic things even today, but we must have far more large scale use of those machines, that the next things would become true.

One of the most fascinating things in nature is the DNA-molecule, which stores genetic information into cells. The role of the DNA is acting like a computer program and control the processes of the cells. That thing could probably give someday another way to store data in the chemical form.

In this vision, the DNA would store the normal data, which is normally stored in the magnetic or binary form. The artificial DNA-molecule would store data like the modern nanotechnical version of the old punch card, where the rises and downs would be read as the zero and one like in optical drives, but the size of that DNA or RNA based optical data storages are very much smaller. And this thing makes possible to make many other things, what are existed only SciFi stories.

The DNA that is stored in the temperature of zero-kelvin degrees, would that thing store data almost forever. 

So this kind of system can send to the planet Pluto or it can operate in really cols place, where a certain form of the DNA would store the data, what should stay forever. The data of this molecule is read by using a very small laser, and when the molecule runs between the laser and the photocell, that thing reads this data storage like other optical data storages, but the difference is that the DNA-based data storages can copy very simple way.

There is one very interesting idea, what is connected with artificial DNA is that the DNA of each human would be stored in the digital form, and if the person would get some illness or gets old, the stored DNA-code can be used to create the copy of that DNA. Then nanomachines simply change the DNA inside the human cells, and that can be the high-tech version of the Fountain of Youth.

Chancing the DNA in the nucleus of the cell is quite easy. There are needed two nanomachines, where is a tank. The first one would pull the DNA out from the nucleus of the cell, and then another one would inject the DNA inside the cell. The problem is that the DNA must change in every single cell in the human body, that this thing would work.

If the thing fails the cell-death would cause the death of a person, who will try to make that thing. But if the entire DNA of each human cells would be changed, that thing would need so large scale of use of the nanomachines, that this thing would be a reality far away in the future. 

The other idea is to use DNA as the form, which can be surrounded by nanotubes. That means that DNA-molecule can operate as a supporting structure in modern nanotechnology, and that means that the bacteria or some other thing would make even kilometers long DNA-molecules, and then the fullerene would just shower to the outer layer of DNA, where to it conducted electricity. And that would make those carbon-bites to touch each other.

In this case, the process benefits the carbon atoms ability to make chains, and maybe that kind of structures would be created for the new space elevator, what would someday in future send the spacecraft to the orbiter. The DNA would act as the structure, and then the carbon would shower to it. One of the most fascinating ideas is to create genetically manipulated bacteria, which would make that thing.

Then over the carbon fiber would install the extremely small magnets, what would raise the donut-shaped spacecraft to the orbital trajectory, and that thing would be a revolutionary thing. But let's go back to think about the use of DNA in technology. The DNA can be used to form the parts to the nanomachines, and one of the most interesting things, where that molecule can be used are the nano-sized tweezers, which can move a single molecule on the layer.

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Who really was Plato, the great philosopher?

When we are thinking about the great philosopher Plato, we are thinking about the man who established the Academy of Athens. And we might remember that this man was a traveler. He traveled in many places in his life and wrote many texts and books, which still is very respected thoughts about the state and other things. When we are looking at the books or series of books, we are facing the thing, that there were lots of texts. If we want to use criticism we must notice that the model of the ideal state is rising the kings in the very high position, and the thing would flatter the kings. And sometimes I have thought that maybe that famous model of the ideal state is written by somebody else. The thing is that the model, where the philosophers rule the state behind the lines of soldiers could be written for the persons like Justinian, who was really flattered. The thing is that this kind of writings was meant for flatter the rulers, who would not persecute philosophers, even they had d...
