Back to the OP:
Scientists have created a material that seems to mimic the self-organizational properties of DNA, but is not, in fact, DNA.
Which is pretty cool.
It quickly reminds me of the countless examples of "ANDROIDS" in Literature-- fully artificial life-forms that are not based on DNA, but are easily as complicated as DNA based life.
The "synthetic beings" trope in Science Fiction.
Brilliant!
It also paves the way for another trope: Fully synthetic replacement organs, to repair ailing humans.
If this new self-replicating material is not toxic to DNA based life, but can exist along side it, or even embedded within DNA life?
It could possibly lead to fully synthetic replacement organs: Imagine a fully synthetic replacement heart, but one that is 100% not rejected, and doesn't require immune-suppression drugs so common with the current heart replacement methods?
Iaasic Asimov wrote a short story, many decades ago, that featured a Choice for a heart patient: A fully synthetic, but biological replacement heart, that got it's energy directly from the patent's own bloodstream, or a fully mechanical heart, that used one of Asimov's "black box" Atomic Power Packs. The surgeon in question was, of course, one of Asimov's Humanoid Robots-- and the scene ends, with the surgeon sterilizing his hands, by placing them into a very high temperature oven ... titanium alloy not being affected by the heat in the least...
I have always been fascinated by fully synthetic DNA-like molecules, and their potential.
Imagine a biological computing machine? One that ran on..... Coke or Pepsi (or any other sugar solution, with negligible trace elements).
"Oh, crap, my iPhone 23 is hungry again. We need to stop a buy it a Coke."
"What? I thought you fed your phone just an hour ago?"
"I did-- but you know that streaming in 16K hologram video eats up the battery, and besides, we only have 87 bars signal out here in the Grand Canyon."
"Yeah, it's so Primitive out here-- I'll text Amazon, and they'll send a flying drone in about an hour-- I have Hourly Prime after all-- may as well use it."
"Use it or waste it, they say. Hey, did you hear Jeff Bezos is going for his 10th full body rebuild?"
"No! He's so vain-- the old body wasn't even a week old!"
"I know, right?"
