Could dinosaurs exist on our planet?

 


Could dinosaurs exist on our planet?


Welcome to Jurassic Park and the strange ideas of genetic engineering. When we are thinking about the things, that some ancient animals would live in the middle of us, it is real. Crocodiles and some other reptilians are examples, that all big species have not died in the great disaster when the large meteorite would drop in the Yucatan peninsula and formed the Gulf of Mexico. If species lived in the sea, it could rise to fly or stay in position, where the heatwave or tsunami of the meteorite would not reach those animals, and some of them still exist in nature. 

Also, some birds are from the age of dinosaurs, and that thing has brought in the minds of people, that some larger species could survive from that disaster. So if some dinosaurs would live in Africa or Table mountains in Brazil, there is a possibility, that some governments want to protect those species. And we must remember that animals like crocodiles are greetings from the time of dinosaurs. 

Could there be attempts to create dinosaurs by using DNA-transfer?

When we are thinking about the possibility to create the dinosaurs back to life by using DNA transfer would seem very naive, when we are thinking that thing. We should find the DNA of the Dinosaur, and then we can transfer that genome in the egg, and that thing would first seem an impossible mission. But then we must realize, that there is well-stored tissue in the big bones of the biggest dinosaurs. 

And we could multiply that DNA by using the PCR (Polymerase Chain Reaction), what is used in the DNA tests and that kind of system can be found in every crime laboratory in the world. In normal life, DNA polymerase would be used to multiply the DNA, which is collected from the crime scenes. But that system can be used to create copies of every DNA molecule, which can be found from the Earth. 

So the from the skeletons of the big dinosaurs can be isolated DNA, and then the genomes of some egg would be replaced by using the dinosaurs DNA. But the question is, why somebody would want to make that thing? Would they want to return T-Rex to life? That kind of thing is not a game, and the most dangerous animal is not any toy, which can be used in some zoos. 

But there is one thing, what we always forgot, and that thing is implanting. What if some people would want to control some dinosaurs by using brain core stimulation. In this case, T-Rex or some kind of raptors would get the microchip implants, which turns them to bio-robots, which can be controlled by a joystick.

Could it be possible to grow the tree in second?

Could it be possible to grow the tree in second?

I just watched the short film from YouTube, where the spacecraft would land on some planet and starts to create a tree, what grows in seconds, and the thing made me think, could it be possible that this kind of thing can be done in the real life. The link to that film named "Abiogenesis" is below this text.

This thing is very interesting to think and the thing that we could make this kind of operation in real life would be a quite complicated process. The idea of this process is to use cell cultures, where are stored cells, what is genetically manipulated for the divide in extremely fast speed, and that thing could be made by turning the genomes to the ring-shaped form, and increase the sequences, what makes those cells divide.

That would cause the very much biomaterial would be created in a short period. Then the cell culture would take to high altitude and after that, the cells would be driven through the system, what looks like the shower. That would drop those cells down, and if the cells would be equipped with genomes, what makes them make chains and then touch together, that would allow creating vegetables in seconds. The cells need genomes, which allows them to create chains very fast and in theory those genomes can be taken from the mushrooms, and after that, the tree should be ready.

But of course, genetic engineering is not so easy, as we want to believe. The thing in genetic engineering is that when the regular engineer is operating with metals and microchips, the genetic engineer operates with genomes. That means that when the researcher, who wants to create new species starts to operate with genomes, that person makes the list about things, what the artificial organism needs or should do, and then the engineer would search the species, what have those certain features, and then the operators will isolate the DNA sequences of those organisms, what could be vegetables or animals.

Then the lasers would cut those sequences away, and then the nanomachines would take those sequences in the certain place of the targeted DNA, what makes this thing very effective. But there is a one really interesting problem with that technology. Each organism or the genomes of the organisms consists the billions of base pairs and being effective this technology needs the complete mapping of genomes of the every each organism on earth.

And after that researchers could locate the certain base pairs of each DNA. After doing this a fictional person would connect the cut bite of the DNA to a certain point of the targeted DNA. The connection would be made by using laser, what cuts the DNA to a certain point, and then the new bite of DNA would connect to that DNA molecule. This is the operation in theory, but there is, of course, some kind of problems with that technology.

First, the mapping of the genomes of the every each organism on Earth would take an extremely long time, and then cutting the DNA must happen at a certain point, and finding that point is a little bit complicated. But if we would someday create this kind of technology, we could store the DNA bites in the laboratory, and multiply them by using the PCR (Polymerase Chain Reaction), what could make possible to create the changes in the wanted DNA.

And this makes possible to make children, who have the wanted quality. This thing would allow us to modify the DNA and that would bring the fascinating but at the same time terrifying images in the front of our eyes. Maybe in the land of tomorrow, we could create "super scientists" as well as "super soldiers", and that thing makes us face the new kind of social and communal pressures and the problems with legislation and many other things. One of the biggest problems is the moral and ethic problems what are causing problems with the juridical position of that kind of projects.

There is also shown futuristic and yet fictional drones, what are based flapping wing technology, and in the real-life, those drones could search hydrocarbons by using mass-spectrometers. The thing is that those wings can operate the same way as the wings of bugs. This means that they could be stored in the small space, and when those wings are needed, the small tubes inside them would be filled by using the liquid, what allows to create wings, what can store in the small space. The same technology could be used in the rotor wings of the helicopters of tomorrow.

The lightweight flexible carbon fiber would allow creating rotor wings, which can put in the pocket. And then the wings would be blown in the right form by using pressurized air or liquid. That thing might make possible to create the helicopter, what can carry in a backpack, and what is invisible on the streets. Then the operator would blow those wings to form when that person needs them. The system might use a rotating rotor. And that structure would be suitable for small size nano-bugs, what must operate in narrow conditions, and what should fly away after the operation.

About the shape of the molecules

About the shape of the molecules

The form of the molecule is very important when we are thinking about things like DNA-molecule. Those molecules are looking like spiral staircases, and they are almost every time straight, which means that they are always wires, what has beginning point and the end. But what would happen if the human or higher animal DNA turns to wheel form?

If we would connect the magnetized iron bites with opposite polarity to both ends of the DNA, would turn that molecule to the wheel. That would make this molecule the largest plasmid in the world. This thing could be made by putting iron atoms in both ends of DNA, as wrote earlier, and if there would be the magnet field, what magnetizes those atoms, that would make possible to make the DNA plasmid by using human DNA.

The DNA is acting as the computer program, which would transfer the data of the cell to the next generation. That molecule contains every information, which is needed to make some bacteria, cell, or complicated animal. 

This thing means that DNA or genomes are interesting the people, who are creating medicines, but also people who are working with normal technology have seen, that DNA is a useful tool for many purposes because this molecule can be used as a tool in nanotechnology. The form of DNA makes possible use that thing as pliers, what can transfer small molecule-sized particles in another place, and this would revolutionize the nanotechnology, but this is known over ten years.

But if we would think the end of the DNA, we would think that there is the thing, what is called "programmed cell death". That code of DNA forces the cell to death. When we are thinking about the DNA and chromosomes, there is also the telomere sequences at both ends of that molecule and the thinning of those sequences is connected to elding.

There have been introduced one very wild idea to make the stern cells of human young again, and it is that the researchers must only cut the old telomere sequences off the genomes, and put the new ones in those places, and this thing would make possible to make the stern cells young again. But there is one thing, what makes those things difficult, and it is that the that those telomers must be part of the same DNA, what should make younger.

So what must be done in this case? There is one possible action, what kind of things must be done, and that is that the stern cells or the DNA of the just born person would be taken to store just after the born of that inmate. And then the stern cells would be manifold. Or actually, the DNA must only be manifold, and for that thing should use the PCR (Polymerase Chain Reaction), what is the normal tool in crime laboratories.

Then the nanotechnical machines would cut off the telomeres, and then they would put in the cultures of the cells, and that would allow them to change the telomeres in the chromosomes of those cells. Another version is to create an artificial virus, which will transfer the DNA of the stern cells to the cells, what genetic material has been removed. 

That thing would allow creating artificial stern cells, and some people have claimed, that we could create the method, how we could live forever by using this kind of technology. The DNA of the just born child or the stern cells of the fetus can be stored in the digital form, and if we would live 300 years from now, we would possible to use nanotechnology to create artificial DNA, what can be used to replace the damaged version of genomes.

But the thing, what causes the elding process must be eliminated, and the DNA must be stored in the chemically and radiologically stable areas because the radiation and chemical stress are making damages in DNA. The problem is that the telomeres or the DNA must be changed in every cell in the human or some other species body.

This would be a really hard operation for the nanomachines, but in theory, there is a possibility to create the machine, what can pull the DNA out from the cell, and inject another DNA inside the nucleus. In laboratories, the human operators would make that kind of things, but the thing is that this operation must be done with all cells in the body. Even this thing is in a hypothetical level, the idea, that we could replace the damaged DNA or telomers by the new ones would be interesting.
