what does /sci/ think of low dose Naltrexone?
>LDN is a promising treatment approach for chronic pain conditions thought to involve inflammatory processes
>Naltrexone could alleviate depression symptoms in patients who relapsed while taking antidepressants
>"Low Dose Naltrexone changed my life for the better. If I had not added that to my regimen, I would still be suffering from nerve pain and uncontrollable allergy symptoms, in addition to the problems I have from the Hashimoto’s [Disease].”
>While only 38% of those that tried Low Dose Naltrexone reported feeling better, the ones that saw benefit had some spectacular results. 48% were able to reduce thyroid antibodies, 61% saw an improvement in mood, 66% were able to have more energy, and 40% saw a reduction in pain.
>"LDN could change the lives of millions of patients"
>70% of Norwegian general practitioners (family doctors) have now prescribed LDN "the proportion of LDN users went from an insignificant number to 0.3% of the population"

hmm in terms of inflammation i think a rheumatoid doctor has to work with it. inflammation such as arthritis? in terms of arthritis apparently those with larger leg muscles can recover much easier than other who have frail legs (as in arthritis in the knee). at the same time people abuse the shit out of pain killers. pain is very relative too. someone could have some pain and say its an 8/10 on the pain scale. little do they know an 8/10 is amputation type pain...
Could this drug fall into such overuse?

Ketamine is much more effective for alleviating depression symptoms

so recently i have been taking up some maths in my spare time over the holidays to give me an advantage before going back for my course. I have been studying, or mores accurately just stared studying calculus. Im a bit confused on how to get an answer for:
Were are given a value for R, first = 5 then =4
I understand that (δ R) squared = 1 how i am confused what δ (R squared) would equal.

How exactly do a person's muscles allow them to do something like throw a punch when all they can do is contract?

I have a rough guess that muscles in the pec and shoulder lift the arm while a muscle on the back of the forearm tugs it back to extend it, but I don't know enough about biology to know if I'm retarded

Well, I tend to trust researches done by English speaking researchers instead of the ones done by the ones that speak my native language. But that is more related with the fact that it means they are probably from first world countries and might have taken it more seriously also that they could access a larger amount of information on the subject they researching.

Genetic weakness shouldn't be praised like it has been for so long. Unless you want to eventually go full manipulation mode with genetics it's detrimental to the whole of our species. Also th selfishness of men and women waiting until their late 30/ and early 40s and then being shocked they have trouble or a retarded baby is hilarious. Bad eggs are bad eggs. Bad sperm is bad sperm.

Has anyone ever considered using the energy density and weight of heavy materials like Uranium in engines of controlled fusion. It seems like with the kinds of energy states in fissile reactions you ought to be able to get some fusion happening.

We do it with bombs at the very least.

Actually it's the opposite. Fusion reactors theoretically allow you to use fissile materials more efficiently.
>https://en.wikipedia.org/wiki/Nuclear_fusion%E2%80%93fission_hybrid
A big issue with nuclear reactors is the huge amount of energy that goes into the fuel as well as the problem of nuclear waste. Spent nuclear fuel can be used in hybrid reactors until completely depleted, so it would simultaneously increase the return on refining isotopes and be a nuclear waste disposal method.

How far are we from creating self-sustainable energy in space? I'm talking things that would help us carry missions farther than the budget and send ships and probes into space farther than the on-board fuel allows them to? Can a ship/probe gather and harvest materials from asteroids to convert to burnable fuel? We've got a lot of metals we could burn to conduct energy. yes? Logically, once the momentum starts, the only energy we would need is to continue broadcasting data as well as turning, correct?

we'll be able to do all of that the second we can build probes and scientific instruments in space itself
once we get that, weight will no longer be an issue, and we can make them into full blown science ships with every instrument imaginable for what ever mission is desired

considering there's no less than five different companies working on extracting and refining space resources right now, as well as multiple governments, 10 years tops
>>
>>9096622
You have some basic terminology errors.

We have had "self-sustainable energy" since the first spacecraft: solar energy. Once the solar panels unfurl, every space mission has as much energy as it could ever want.

>Can a ship/probe gather and harvest materials from asteroids to convert to burnable fuel?
No. Fuels are typically volatile, so they have not remained on the tiny asteroids. Planets like Mars are a better place to make fuel.

>We've got a lot of metals we could burn.
False. You don't burn metals.

Basically, you are conflating "energy", "fuel", and "propellant". Energy is space is free (solar power), but propellant (reaction mass) is scarce. Fuel is basically propellant which contains chemical energy.
>>
>>9097577

If we sent a shuttle/probe beyond our solar system, would it still be able to get enough solar energy to continue, or at least continue broadcast? I know that's a long shot, and signals would take ages to transmit back to us, but it's like asking is the ship is dead or just in a coma and going to wake eventually?
