Breakthrough: Scientists Revive Cryogenically Frozen Life


If you’re part of the crowd that wants to live forever (imagine the boredom), today’s news is about a major scientific breakthrough with regard to cryogenics. Truth be told, I don’t really understand why people believe they can “live” forever using cryogenics, i.e. to get in a (perpetual?) state of suspended animation, hoping they can be revived later from their frozen state. Okay, I’ve read Philip K. Dick’s novel Ubik, but that’s just science fiction, alright? Cryogenics as in suspended animation could prove very useful with regard to space travel over huge distances, but that’s not living forever and we’re digressing.

Getting back to our story, US scientists are now one step closer from freezing-defrosting humanoids (for later use, right?), as according to a recent study, it seems perfectly possible to preserve one’s body (and hopefully their brain) in a state of suspended animation. Basically, it seems doable to freeze a person to sub zero temps and revive the respective individual later on in the future.

So far, that “kind of magic” was achieved using zebra fish embryos, but you know that saying: one small step for a zebra fish embryo, one giant leap for cryogenics. The thing is, for 60 years scientists tried and failed with similar tests and until now, reviving even a frozen zebra fish embryo proved to be unsuccessful. The problem with freezing something organic is that the water inside cells expands and tears up the respective cells/tissues. The scientists mitigated the problem by adding guess what: an anti-freeze substance. But even with the anti-freeze injected, there were significant problems during the defrosting process.

To quote from the medical journal ACS Nano:

“The large size of the yolk still impedes rapid cooling and warming, thereby yielding lethal ice crystal formation during cryopreservation.”

Things changed dramatically when gold nano rods were added to the anti-freeze solution. The minuscule golden rods are then hit by LASERs, which allows the embryos to get warm very quickly, as the gold is a great heat conductor for the LASER’s heat. So far, about 10 percent of the fish-embryos survived the defrosting process. It’s not much, but it’s a start.

One may argue that at the rate this world is declining with third world immigrants invading and taking over first world nations, I don’t think I’d actually *want* to wake up 100 years from now (or whenever). It would be a global wasteland except for countries like China, Japan, South Korea or Russia, who had the guts to keep illegal invaders out of their nations.
