You know what also changes a body permanently? Your mom sitting on it. #gottem
Well, duh, I’ve seen the fantastic four.
How can they say it’s permanent when it was only 6 months of data and the astronaut is still alive?
Probably the same way we can know things like if you break a glass, it’s gonna stay broken. Or if you cut off a finger that it stays cut off.
Probably seen telomere damage from radiation or some such. Some sort of thing which doesn’t grow back naturally. So sans technology that will change our biology, we know some things are permanent.
Although like 20 years ago I could’ve used a tooth falling off as an example, but I first read about tooth regrowing studies in a science mag in the early 00’s and 20 years later we’re kinda there actually. The researchers hope to have it for general use by 2030. A tooth regrowing drug! Phase-1 human trials already concluded without adverse effects.

I’ve heard about the tooth regrowing so much I’m like “ehhh never happening in my lifetime, got it”. I hope I’m wrong!
My dentist brought up what a bunch of bullshit that is at my last visit. He was saying that the drug causes teeth to regrow but we don’t know the side affects, or what else it will make grow. He made a good point that there are other places on the body that are somewhat predisposed go grow teeth given mutation. He mentioned this is why we sometimes see people grow teeth in their genital area.
Anyways, I’ll stick with bridges and whatnot personally.
Yeah, tumors love to grow teeth ;_;
The drug is basically ready to use. Just going over safety checks and they hope to have it out by 2030. So unless you plan on dying within the next few years, high chances it’s happening in your lifetime.
Which is good news for me, I lack 4 permanent teeth congenitally.
But I definitely know what you’re talking about, having heard about it on/off for literally 20 years. I think this team/research started in 2005.
I’m still waiting on the 3d printed spare organs. Read about those in the early 00’s as well. I think they’ve managed a rabbits heart already. A functional one.
they were able to print a rabbit-sized heart with a network of blood vessels that were capable of contracting like natural blood vessels. The printed heart had the correct anatomical structure and function compared to real hearts.
Yeah that makes sense. Still seems like a bold statement but I can see where you’re coming from.
Time machines
Oh yeah. Good point!
Newtypes are the future. Those whose souls aren’t weighed down by earths gravity will chart humanity a path that saves earth from the gluttonous earthnoids
Ya, Beltalowda beratna!

Permanent changes means no epigenetics. So probably mostly radiation? Probably teaches us to improve radiation shielding. Which is pretty simple, just put the water storage on the inside around the hull.
Simple eh, so basically surround yourself with an aquarium
Worked for our ancestors before they got tougher against radiation
You need only a few centimeters of water for shielding.
I’m no scientist, but wouldn’t that mean the water becomes irradiated and when the astronauts drink it they’ll still be getting approximately the same level of radiation they already are?
Negative, it only gets irradiated if the water comes in contact and gets contaminated with radioactive material. Just like the cooling water that flows out of a nuclear power station is not more radioactive than the water that goes in.
Actually it technically does get irradiated by neutron activation, but the half life of Nitrogen-16 is only 7 seconds, so by the time it reaches the filters it’s already poof decayed away. (Very small amounts)
Thanks. Good to know
What til they get the results on what living on Earth does
Not as much as lack of space!
I worry they’re looking at all of this space data in a vacuum.
Well. Buzz lightyear is still alive at 96
Pretty sure Toy Story came out in 93 or 94, meaning Buzz is only 32 or so.
But what you dont mention is he was already 60 at the time somehow
