mahenderkar , in How far is reverse aging tech?

@UraniumBlazer
To solve reverse aging, we first need to understand how to stop it first.

mahenderkar ,

@UraniumBlazer
To stop it, the net has to be flatlined. i.e, = .
For that, I believe intake is the key. It's like cells, the lesser you provide oxygen, the more it grows. Same goes to a lot of other cells.

UraniumBlazer OP ,

Yeah, the antioxidant thing was debunked decades ago. It was the leading hypothesis like pre 2000 from what I know.

Who the hell would want to live forever? What kind of egomaniac thinks they’re so important that continuing to live is a good idea? Jesus Christ.

Mr_Blott ,

Were you answering your own question there?

UraniumBlazer OP ,

Lmao

mahenderkar ,

@the_q @UraniumBlazer
I think the goal here is not properly defined.
A human is just a , with a attached to it. The question is, how to keep this body healthy, so that our mind lives longer too.
Actually, if we have the ability to properly separate body from brain, do you know that our brain can live forever ?

UraniumBlazer OP ,

So your proposal is transhumanism. Replacing the human body with something different. This is a very interesting discussion for futurology, but I am unaware of any advances in this field.

UraniumBlazer OP ,

Who the hell would want to live forever?

I want to have choice over when I die.

What kind of egomaniac thinks they’re so important that continuing to live is a good idea?

So if I break into your house and try to kill you, would you be an egomaniac to resist? If you get a heart attack and if you rush to the hospital to get yourself treated, are you an egomaniac?

the_q ,

Well I have a DNR so…

hakunawazo ,

TIL what a DNR is.
en.m.wikipedia.org/wiki/Do_not_resuscitate

I thought DNR is some lesser known brand of gun in case someone breaks into your house.

Umbraveil , in How far is reverse aging tech?

Should we hope to get drugs/treatment to cure this in the next 10/30/50 years?

I sure hope not. What a shit show that would be. People need to die, it’s just part of life. Assuming it would even be possible, don’t think for a second us normies would be eligible. This would be for Trump, Musk, Bezos, etc. I couldn’t imagine how it would impact resources and population overtime.

Sinclair has a well earned reputation as a charlatan.

NegentropicBoy , in How far is reverse aging tech?

Sinclair and Dr Stanfield ( www.youtube.com/ ) don’t always agree on things.

UraniumBlazer OP ,

Yea, this too. I can’t figure out if this is just a Bohr vs Einstein situation or a dumbass vs smart guy situation.

surewhynotlem , in How far is reverse aging tech?

Sinclair is ok. He wrote a book called “lifespan” that’s pretty well regarded. Also look up Aubrey de Grey. His book, Ending Aging, is also good. He himself is problematic though. If you’re interested in this sort of tech, also look up the SENS foundation (I donate there).

Fair warning, most everything focuses on increasing healthspan, not lifespan. I.e. Being able to be active and alert at 90. There’s no way for tech to guarantee an increase in lifespan within our lives, because we would need a few generations of evidence to guarantee that. So at most you’ll get partial evidence and animal models. But you gotta start somewhere. And if we’re lucky, we’ll stop be around for the ‘proof’ in 200 years :-)

UraniumBlazer OP ,

Wouldn’t healthspan and lifespan go hand in hand tho? Like… I can’t imagine a 99 year old going for a marathon today and just dropping dead tomorrow due to old age. Wouldn’t an increased healthspan also include an increased lifespan?

yuriy ,

Probably? I think the difference is the reasearch is going into meaningful things, such that would keep you healthy rather than just alive. I think it’s just a matter of semantics though.

I would trust your instincts on this guy.

Science has known for years that the fewer calories you ingest, the slower you age. Metabolic processes induce a lot of wear and tear.

As far as reversing aging, the protein thing may have some merit, but I would remain skeptical for now. My 2-cent guess is that truly reversing aging will involve some unholy cocktail recipe of stem cells, genetic manipulation using CRISPR, lots of fasting, and maybe some advanced vaccines (we’re learning vaccines can train the immune system to do all sorts of interesting things beyond fighting infections).

UraniumBlazer OP ,

Wow, never heard that before! Like what? Sorry, I’ve been completely out of the loop for developments in the genetics space.

That’s amazing

UraniumBlazer OP ,

Oh wow, the rate of progress everywhere is just so high! What a time to be alive!

missing_forklift , (edited ) in Has a vaccuum chamber ever been used for desalination?

yes you can do this, however notice: this is wasteful as you have to run pump and heat from steam condensing is not recovered. You can heat up incoming water with condensing steam - this is called vapour recompression distillation. alternatively you can use heat pump to move heat around

missing_forklift , in Attempting to freeze matter under extreme pressure?

You’re thinking of gases. In condensed phases energy is just stored as a potential energy coming from the fact that molecules are too close to each other (going left of that minimum en.wikipedia.org/wiki/Lennard-Jones_potential). You don’t have gases under such conditions, they condense

Jeredin OP ,

@missing_forklift gave me the answer that I was originally after. Still, thank you for replying to my question.

Omega_Jimes , in Is the "Tromatz" bioelectric wave toothbrush legit, or snake oil?

Oh man, someone send this to Mhedi at ElectroBoom! I want to see him make an AC toothbrush!

CanadaPlus , (edited ) in Is the "Tromatz" bioelectric wave toothbrush legit, or snake oil?

Based just on the name even, snake oil. WTF is a “bioelectric wave”?

xkforce , in Has a vaccuum chamber ever been used for desalination?

You could but the reality is that using a semipermeable membrane and a difference in pressure is more energy efficient.

Steve , in Is the "Tromatz" bioelectric wave toothbrush legit, or snake oil?

“The new TROMATZWAVE® technology uses a hybrid electrostatic force, simultaneously imposing both AC and DC on a micro frequency of 0.7 V to disturb the electric charges and subsequently break the EPS barrier”

This is mostly gibberish, especially the part where they describe a frequency in volts. (Completely incorrect)

athos77 , in Has a vaccuum chamber ever been used for desalination?

Leaving this here to display my shame.

Why be ashamed? You had an idea that's probably never occurred to the majority of the people on this planet, and you asked for validation. A) that's original thinking and b) that's the first steps in science: I have an idea, is it reasonable, how can I experiment with it? I think this is a fantastic post!

CaptainMcMonkey OP ,

Self depreciation is a load bearing coping mechanism. I’m not sure I can turn it off.

CanadaPlus ,

Yeah, OP didn’t even phrase it like nobody else could have thought of it, which is a frequent pitfall for these kinds of questions. The experts that can give the best answers hate that. It’s implicitly saying their years of study aren’t worth much.

Steve , in Has a vaccuum chamber ever been used for desalination?

I could be wrong, but iirc even tho you can boil the water at lower temperature, it still takes the same amount of energy to change phase, so the efficiency gain isnt as spectacular as you might expect.

Brokkr ,

The energy to change phase, the latent heat of vaporization, does decreases. Enough such that the ambient temperature is able to supply sufficient heat for vaporization (that is, boiling). The latent heat of vaporization is temperature and pressure dependent for most materials.

Steve ,

Akshuly, the charts I can find on the subject of enthalpy of vaporization vs pressure say the opposite- it increases at lower pressure

For example: researchgate.net/…/The-enthalpy-of-vaporization-s…

Brokkr ,

I could have gotten it backwards. Depends on how the system is being defined and which direction the heat is going.

Steve ,

I do agree that at some point ambient temperature does the job, which is obviously super convenient.
