DNA, the molecule at the heart of life, is the most powerful and sophisticated information storage device in existence. So it’s no wonder that scientists are attempting to harness its capabilities in computing and electronics. Not only does DNA have the capacity to store vast amounts of data, but it also provides the opportunity to surpass current limitations on reducing the size of electronics.
Although we’ve drastically shrunk computers since their advent, scientists can only go so far because a minimum space between transistors-- the main building block of electronic devices-- is required to prevent interference. This means that processors can’t be designed much smaller than what we have around today.
DNA could provide us with a unique way get around this, but unfortunately, scientists have faced a considerable challenge with using it in the field of “molecular electronics,” or the use of molecules in the production of electronic components. It’s easy enough to design and fabricate DNA-based molecules, but transporting significant electrical current through them has proved arduous. Furthermore, measuring the flow of currents through synthetic DNA strands has previously always produced contradictory, and therefore unreliable, results. But now, an international team of researchers, headed by scientists at the Hebrew University of Jerusalem, has made a significant breakthrough that represents a giant stride in the development of DNA-based electrical circuits.
As described in the journal Nature Nanotechnology, the scientists made their DNA-based wires by absorbing four DNA strands onto a mica substrate. They were then able to accurately and reproducibly measure the currents flowing through these molecules, which ranged from tens of picoamperes to over 100 pA. Furthermore, the current travelled distances greater than 100 nm.
“This research paves the way for implementing DNA-based programmable circuits for molecular electronics, which could lead to a new generation of computer circuits that can be more sophisticated, cheaper and simpler to make,” lead scientist Prof. Danny Porath said in a news-release.
The secret to Yap’s gold-and-nanotube device is its submicroscopic size: one micron long and about 20 nanometers wide. ”The gold islands have to be on the order of nanometers across to control the electrons at room temperature,” Jaszczak said. “If they are too big, too many electrons can flow.” In this case, smaller is truly better: “Working with nanotubes and quantum dots gets you to the scale you want for electronic devices.”
“Theoretically, these tunneling channels can be miniaturized into virtually zero dimension when the distance between electrodes is reduced to a small fraction of a micron,” said Yap.

So here is some old healing with eletricity technology, the book "The Body Eletric" deals with the specifics of how low frequency eletricity can be used to not only regenerate damaged tissue but also change DNA.
I imagine with this technology people could heal any injury instantly.

As far as data storage on DNA goes, this has already been done. A British team successfully encoded a book into DNA and was able to read it back...the problem is though, it takes days to extract the data and 'read' it in any meaningful way. So really, at this stage in the research, as gigantic a storage media DNA has the potential to be, unless we come up with a better method for reading the data encoded (more akin to how our own bodies read the data in our DNA i presume), DNA data storage will only be suitable for long term archiving situations and not real time computing where speed of access to data is important.

It's called called Rife technology. Beside killing pathogens in the body it can be used on DNA.
I have a scalar DNA transmitter that allows me to use it without any contact pads.

Greetings,
The technology you're talking about has been in use for about 75 years.
It's called called Rife technology. Beside killing pathogens in the body it can be used on DNA.
Big pharma and the USeless gov have been suppressing it for many decades.
I've been using for about ten years. If fact I'm using it right now. I have a scalar DNA transmitter that allows me to use it without any contact pads. I'm free to move about as the unit is sending frequencies to my body.

I think Tesla may have been moving towards an anti ageing long life with electricity theory.

reportedly he was life long vegeterian. lived to ripe old age. still look good at advanced age of 89. frequently takes "ac electric bathes"? reportedly the technology never caught on and commerialized cuz never proven safe and people iniatial impression was fear of such a concept.
so might the"ac bath" actually contributed siginificantly to his health that no one have been studying?

Except he was essentially a very high functioning schizophrenic, who looked terribly aged in his last few years, would have won Mr Annorexia award, and his only friend was a pigeon. Pigeon bounced, and he faded away. Funny how people wanna exaggerate his awesomeness and deny his negative, bizarre behavior.
I'm okay seeing him as he is. Beyond brilliant, genius that had serious issues, all the same. All of that being said, he might have been onto something with ac baths, but I think most of these modern devices are quacky. Maybe when we know more, and can fine tune such tech, might be useful.
oh and did someone seriously say he was a vegetarian? not so. dude could eat two to three steaks in a meal. he also useed to go up to a week without any noms, hardly any sleep. like einstein, would work himself until complete exhaustion. You can't do that to your body over and over again and not have some serious malfunctions arise.
