So far, nada, zip, zilch. Nothing really being manufactured with it.

huh ? ever hear of carbon fiber ? ever read about all the things made with composite threads ?

Nope. Carbon fiber and graphene are totally different things. Carbon fiber has been around for decades, and is as you say used in a lot of stuff.

Graphene is different. It is an atomic-scale level hexagonal lattice, made of carbon atoms. Image a sheet of material that is only one molecule thick. It is so thin that if viewed from the side (the edge) it is invisible to the human eye. It is about 200 times stronger than steel.

It is crazy stuff. It is so thin that if you made a single long strand of it, maybe three molecules wide, and stretched it between two points, secured at each end, it would still be invisible to the human eye. But, if you accidentally passed your hand through it, it would cut your hand off. Being only one molecule thick, it is hundreds of times sharper than a razor.

Graphene isn't a composite. It is a molecular lattice of carbon atoms.

As far as growing human organs in pigs that never did pan out. There was still the problem with foreign tissue rejection, even inside the pigs who died. Now if it were possible to grow an organ useing your own DNA that would be a different story. But once again we are dealing with the cloning research like was being tried years ago, which also was a complete failure.

Enter the bio mechanical research on workable replacement organs or limbs, which would be made from an inert substance your body wouldn't reject. The dream in this is, to perfect some sort of a modem where the replacement part works in conjunction with your own nervous system. Last time I read anything about this, replacement eyes or restoring vision was the focus.

What you are saying is true. They haven't successfully grown a human organ yet in a pig.

But, last month, around January 26th, the big news was that for the first time, scientists have gotten human cells to successfully grow inside a pig, by implanting them in an embryo. They are alive and doing well.

The story is widely reported in National Geographic, the New York Times and the Washington Post. Pretty interesting stuff. What I think they will end up doing is taking a pig embryo, destroying the pig DNA inside of it that grows a pancreas, insert human stem cells into it for the particular person needing the pancreas, and then implanting the embryo inside a mother pig. The baby pig that is born will be growing a new pancreas for the person.

So, instead of dying from diabetes, the person gets a brand new pancreas and can start over again.

But, you are right. It is probably decades away.

That's a good post manny, but all I can see in that research is a wide open door for something to go horribly wrong. How about producing some sort of bio mechanical media which is of course DNA neutral, that a pancreas itself could grow in? I've seen some research into this as well. I sure would trust that over a human organ that grew inside of a pig.

Something that's akin to an egg or an incubator useing only the patients targeted DNA. Keep an eye on this bio mechanical research.It is not a machine in the sense we know one as, it's a constructed media from the ground up that would mimic anything we wanted it to. Even mimic something like a uterus capible of supporting cell growth in a controlled environment. Taking it even further, not a real human but a true to the word Android, and not a cyborg.

But as you said still decades away. But I believe we will see human cyborgs before we ever see a true Android.
Humans with bio mechanical parts and organs which our body's would not reject. Anything else is just a machine.

I think that what you are referring to is definitely in the works, and has in fact been successfully done, using a 3-D Printer, which sprays a media solution containing stem cells plus pancreas cells (instead of ink).

After a human pancreas is scanned by a computer, the Printer sprays (prints) the solution on a man-made piece of screen (instead of paper), that is made of a bio material that will not harm the human body.

With each pass, the printer sprays another piece of screen and puts it on top of the prior piece. This causes the stack to grow higher and higher, in the shape of the pancreas, but sprayed with stem cells and pancreas cells.

Then, I think that the whole thing is put in another solution, and allowed to "grow." I don't know how, but those stem cells think that they are in a damaged pancreas, and simply grow into a new one. The screen material, being a bio-matter, simply dissolves over time.

I believe that this was successfully done in Europe last year, but the cost was over $1 million to do it. Plus you need the stem cells, DNA etc from the person who is to receive the organ.

At $1 million a pop, I don't think we will be seeing these much any time soon. No wonder they are just trying to grow them inside a pig.

Problem is, there is a huge difference between what is scientifically possible, and what is financially possible.

The research that German lab is doing is interesting in what they have done for blind people. By getting the eye and brain to once again
allow a patient who at one time could see, to at least see light again to some degree. By useing the techniques that you are talking about.
One patient could see out of focus images that were only in black and white, but it was better than complete blindness.
A completly missing eye once they perfect a modem could be replaced by a constructed eye.

The German report was saying that any missing organ or limb that was once there, but isn't any longer due to an accident or a disease
where it had to be removed. The nerve endings are still there, and the brain is still trying to send the signals to that missing body part.
Once a body modem is perfected, it will open up a whole new world of possibilities. They can already make the eye, it's connecting it to the brain that is the current problem where a modem could interpret the nerve signals.

But we are back to where that would be a cyborg, a human with fabricated mechanical parts. What you are saying is not, that would be
a bio engineered human, but still a human. But to grow a replacement organ in a pig then put it into a human that practice would be an
Oddtogg which borders on cloning problems.

This stuff can get deep and confusing with all the definitions and classifications. It was a lot easier when we were kids and called all this a robot lol.

I don't know about this stuff, but how often have we heard some research institute claim; "we are on the verge of curing cancer" or "a cure for muscular dystrophy is on our fingertips' or "the end of diabetes is in sight" ...
Grants are rushed in to speed the process...then what ?
