Japanese researchers made banana flies younger using gene transfer. The ability to transfer genomes between young and old individuals and make elder individuals younger is an interesting thing. The gene transfer that made older banana flies younger is the first step in the process which end can be immortality. The ability to turn the individual younger is theoretically a very simple process. 

The system must just change the DNA in the cells, and then the individual can turn younger. The problem is this: how to get fresh DNA. The thing that causes aging is the damage to the DNA. 

Outside effects like chemical stress. And radiation, and things like cell metabolism cause DNA damage. That damage breaks the chemical code in the molecule. 

The thing that makes forever youth dangerous or difficult is that the DNA that the system must transfer must be the individual's own. Theoretically is possible to copy the individual's DNA code into the computer's memory just after the individual is born. 

And then, nanotechnology makes a copy of that molecule. The problem is that all DNA parts have some purpose. And the "Junk DNA" means sequences that cells don't read very often. Those sequences control the advancement of neural systems. If there are errors in the neural structures the person might turn something that nobody wants. 

Another way to make the individual young again is to use the stem cells that are stored in liquid nitrogen. Those stem cells can act as DNA storage that the system uses when it creates new stem cells. The problem is this. Stem cells must be taken before the individual is born. 

Maybe somewhere in the future, all people have DNA, stored in cryogenics. Researchers can store the DNA in digital form. However, researchers can use things like RNA chips to create stable DNA or RNA storage in some laboratories. But when researchers make the DNA transfer. They must destroy the old DNA from the cells. 

Another thing that researchers require is. They must make the DNA transfer into a cell group. That is large enough. The artificial virus that puts enzyme fiber before the DNA can make that DNA transfer. The idea is that the enzyme acid destroys the DNA before the virus transfers the new DNA into the targeted cell. 

If that thing is possible someday. That thing brings new visions for medical and anti-aging treatment. The ability to change the DNA in the cells is an interesting thing.
