Scientists have developed a chemical process by which living cells can be converted to inorganic forms which continue to function as though they were alive, but become nearly indestructible.

Not quite. It's "silification", petrification is a bit different; The main difference being it doesn't work on mono-cellular organisms very well, where this process is akin to a cross between electrostatic plating and taxidermy.

>> No.23321687

>>23321526
But there's more to life than the processes within a single cell.

For an organism to be remain alive, the processes which take place between cells are at least as important as the functioning of each individual cell. Looking at this petrification thing, I can't see how chemicals would pass through the cell membrane if it was a solid shell of silicon. Meaning the petrification process would probably only work on single cells.

Telomorase dictates how often your cells can duplicate, but de facto bodies tend to break down because of general wear and tear and diseases that exploit them. Different life stages, different reactions to these problems, which is why kids' wounds heal much more quickly.

you are a fool. You sit there dumb founded and slack jawed by a process you barely understand. Life began as chemical reactions (and essentialy thats all it is still), individual molecules forming self replicating macro-molecules. All the essential mechanics of life are on that scale because that's the scale in which life originated. Human technology started on an extremely macroscopic scale, its no more astonishing that we have not created nano machinary than it is that life never created cells that are 3 feet across. Furethermore if we use your definition of machineary (chemestry forming functional macro-molecules) humans do that on a daily basis. The chemistry of life is fascinating but not uniquely impressive, when we realize its majesty its not surprising we fall on our knees in awe. The difference between you and real forward thinkers is forward thinks get off their knees and move on.

The point is that we can't, currently, create three-dimensional nano-structures.

No. Stop believing whoever is posting that rubbish. The replicas have no functions. They perform no processes. They are molds of the cells and organelles. The reason that it is important is because it's an easy, cheap, reliable way to create 3D nanostructures and, if nanomachines are ever going to get built, we'll need a way to create 3D nanostructures to build machines with. So, with this method, all that you have to do is find the right cells with the right-shaped organelles to create the parts for a machine that you want to construct, which is important, because we cannot create the pieces for the machines with current technology. This removes the need to create 3D nano-structures from scratch.

No. The cells are dead, and only continue to function as little machines.

No cell division means no healing.

As far as Yes goes, you are definitely correct.
It is definitely them, though. You can't hide their signature voicework, the piano, or the synthesizer behind a single growling guitar. But the fact that they were willing to get that heavy and rhythmic makes me happy.
Although what else would you expect from a band that is synonymous with experimental rock

You need some sleep, buddy. Why don't you go on inside and read some of your Chinese comic books. Your mom will make you some hot coco.

I dunno, it doesn't have the same mechanical feel. It's missing the electronic soar/gallop of Machine Messiah.

There's something vaguely horrifying about living things being converted into undead machines through simple exposure to a certain chemical solution.

And yet at the same time...

the memories of mice are being recorded, decoded and understood, portions of their little brains are destroyed then partially replaced with computers, granting partial mobility, sight, smell, or entirely new senses. The technology is young, inelegant, but soon. We humans change the world around us to suit our needs, soon we will change our bodies to do the same.

Things like the pic related will be a joke in 100 years from now, and our idea of what can be will never be the same.

This is humanity fuck yeah. but for real. Trans-humanism, fuck yeah. fuck yeah /tg/

Anyone happen to have a handy link to the peer-reviewed version?

Because until I see/read that journal article, all of this may as well be a joke.
