Rotating sections (Babylon 5 style) is something we should be doing for space bound ships anyway. Even SpaceX's Starship won't be truly 'space bound', as it will basically be a super shuttle between planetside and low orbit in many cases. It will be fine for the relative short term future to get the ball of the future rolling though. Getting a Lunar based mining, refinery, and shipyard ought to be a reasonably early goal for Moon utilization, in order to spread across the solar system.
@@Seastallion Agreed on rotating sections for space bound ships, it should be like an invasion if we are going to colonize planets. Utilizing Starship would be great for short term flights such as delivery, until then.
As I mentioned elsewhere, an even harder problem is radiation. We can, at least in theory, offer a solution to the micro-gravity issue for long term travel by having spinning space crafts - fairly large ones for sure, as mentioned here - that emulate Earth's gravity with centrifugal forces, but I don't know how we can deal with the radiation issue without heavy protective layers that make travel itself a lot harder. And all of the above is for the travel part only. If you are going to stay on Mars' surface for long, you are dealing with a lot of radiation from Mars itself, according to an article I read last year. A Mars colony will need rotating buildings that also insulate against radiation. This is a very long term project for mankind: I predict we will first develop the robots that can perform the assembly of pre-built parts. The financials don't look good at all.
Look it up. There's this thing called Google. There are supplements that can lengthen your telomeres and possibly keep you healthier. There are also a lot of snake oil salesmen.
@@timmykirls2352 look up nmn, I believe they've recently started human trials. Rodent trials have proven pretty successful so far; a mouse that's the equivalent of a 90 y/o human, essentially becomes equivalent to a 20 y/o human.
It's pretty clear at this point, we need to "walk before we run"...ie. setup a Moon base before we go on to Mars and beyond. There are huge medical challenges awaiting us in space and we have barely scratched the surface.
Its pretty clear they never went to the moon 6 times under Nixon in 1972. And no country or Nasa has ever been back. The story is losing its magic, its a hoax its over. Its been too long and how could they have gone if they have not gone since 72. That's for you guys to marinate on.
Or we need to give up on the entire idea of space travel and colonization, because it's not natural. We need to focus that energy on repairing our planet.
@@Treaxvour It's "not natural" for humans to explore and find out more about our world and universe? What could be more natural than that? It would be more unnatural to just quit exploring the universe.
The short take: extended exposure to microgravity harms blood flow, bone density and some aspects of cognition. However, epigenetic changes, increased chromosomal telomere length and certain brain functions my have unexpected positive effects. Astronauts may live longer, evolve faster and develop new brain functions if they don't mutate too fast and die.
Above & Beyond Vapor however you missed something pretty important, telomeres rapidly decrease on back on earth and return to almost post flight level (less i beleive) which is quite bad to my understanding
@@NKJFVIDS I caught that, but I was thinking of astronauts on long term flights or existing in microgravity for a long time without returning to earth. Astronauts living on small moons or asteroids or in interstellar travel or living permanently on space stations at Lagrangian points throughout the solar system.
Speaking of collagen's impact on structures of the human body, maybe check out Ehlers-Danlos Syndrome - a family of genetic connective tissue disorders that have a huge range and severity of symptoms. Some cardiovascular symptoms were mentioned in this video, but depending on their subtype, EDS patients can naturally have collagen that is so weak or malformed, they may suffer from spontaneous organ rupture, or their joints dislocating multiple times a day.
... and, unfortunately, radiation: we can, at least in theory, offer a solution to the micro-gravity issue for long term travel by having spinning space crafts - fairly large ones for sure - that emulate Earth's gravity with centrifugal forces, but I don't know how we can deal with the radiation issue without expensive, and heavy, protective layers that make travel itself a lot harder.
@@GlimmerOfLight , yes very large spinning aircraft will more than likely reduce most of those seemingly ill effects of micro-gravity. This would probably cost too much to construct in outer space right now, otherwise why aren't NASA or other agencies and commercial companies doing it? They know how to do it, they just don't have the economic resources or prioritization. As for radiation, it depends where your craft is, if it's past the Van Allen belt, yeah you might want a super conductor like MgB2. Low Earth Orbit still has several hundred times more radiation than Earth, but I believe is far greater past the Van Allen belt. There's other thick ways to block radiation, with water, and what not, but it requires huge crafts and it comes down to economic feasibility again. However, research on MgB2 spacecraft shielding may or may not have lost funding, so maybe it couldn't scale up cheaply. "Asteroid clay is a better space radiation shield than aluminium" - New Scientist Astronauts are getting high-tech vests to protect against radiation - Wired Astrorads are supposed to be getting a trial later this year with NASA's unmanned Orion, deep space mission (EM-1) that will go beyond the Moon launched by the SLS, but it could be delayed until June 2020. It is also suppose to be getting tested on the ISS as well this year.
@@Hozzizay the iss is a microgravity laboratory.. If you gave it a ring and spun it you might just do the experiments on the ground. That's why it is the shape it is.
GlimmerOfLight Actually NASA has done research about spinning in microgravity, but humans get nauseous and basically seasick because their head and feet would experience different forces. Having a spinning section of the ship isn’t really a viable solution.

It's great that you took the time to explain the nature of changes in the DNA, that it's mostly epigenetic.

This video has more to do with the effects of the lack of gravity on the human body, due to being in low Earth orbit. Whether you consider that to be in space or not doesn't affect the results of weightlessness.
@Spartan 506 The air is so thin at that height that it is a near vacuum. The air pressure drops with altitude, until a near vacuum. But there still is a small amount of air, which is why satellites eventually slow down and fall back to Earth, unless they are boosted to a higher orbit, as happens on a regular basis with the ISS.

So you can only spend so much time in space without permanent damage ? We have a long way to go before setting up a permanent base on mars or even a long visit.
Mars is 40% earth gravity. People on earth weight 500lbs and walk around. So if u take a 180lb eather and do the math they would be 72lbs on mars. Add 60% weight on your body. Building the muscle wont be a problem, they may be weaker but should be able to get around. Only thing i can't specilate is the bone structure around the brain, will it affect anything? Maybe spend time in decompression, a gravity increaser in orbit around the moon that slowly spins faster from 40% g to 100% g over a span of time say a month or more.. when ur body is adjusted and u come back to earth.
@@thesisko4031 thats alot of shit to keep functional. What im concerned about is that a moon or mars base would not be a place you can raise a family. Making it a place to visit, but not to stay.

No well-informed statistician will take the results of this study seriously. simple example: Twin 1: N features were measured at M time points before and after leaving the earth. Twin 2: N features were measured at M time points before and after twin 1 leaving the earth. There are two problems: 1- The observations within each twin are not independent from each other (blood pressure from twin 1 at day 1 is not independent from the blood pressure of twin 1 day 100). There is a solution for that, we use what we call linear mixed models, these types of models can correct the dependence between the response variables using what we call random effects (I'm sure the great statisticians at NASA thought of that). 2- However the second problem is the objective of the study. Which is to demonstrate a difference between a person living in space for X period time, against, a person living on earth for X period of time. Here the fundamental experimental unit in the person/human, therefore in order to have a non-biased design of experiment, the fundamental unite must be randomized, in other words, a sample size of 2 is not the correct approach, even if we have multiple results from the two persons.., any significant results from the statistical tests cannot be taken into account, the power behind these tests are incredibly low when taking into account the experimental unit. To be fair I can see why they did the analysis only with two people (twins, budget, experienced astronauts), however, to go and inference the finding of this on the whole population is a long long jump of faith and has nothing to do with science.

You just have to see what a rover can do in 10 years and compare it with what a human crew could do in a couple of weeks. Spoiler, the human crew can do much more.
@@jorge8596 I'm actually not sure what will happen first, a human Mars colony or the development of fully sentient or near-sentient AI's.
@@unfetteredparacosmian sentient ai sounds like a dumb dream and it's funny because if you ever programmed you would know computers are stupid and they excel at doing calculations. While going to mars t's only a problem of money, better suits, more gen studys and Time
If you see your calculator you don't think its concious so it is fair to say more complex calculators are not going to become something more than a calculator, something that is programmed doesnt have the free will of a human and ergo it's fair to say they are never going to develop an actual concience.
All i am saying is going to mars is actually feasible while sentient AI is weebs that never programmed thinking that robots will suddenly awake. This is so stupid as the liberal crowd that loved Detroit becomes human because it had a cliche sjw story and good enough graphics.
@@latioswarr3785 No, it's not like robots will awaken by themselves. What it is is sufficiently advanced algorithms able to simulate sentient, humanlike behavior. As to whether they *really* would be sentient beings, that's a question left to the philosophers.
(Also I liked Detroit Become Human but the story was fairly meh given the premise and the gameplay)
What about age difference? Did it affect aging
That's pretty much what they were testing.
米空軍パイロット I heard it started few years ago and now we have the results but no information on the hot n spicy stuff
@@whatever0000 The telomere stuff is what you are looking for.
It's great that you took the time to explain the nature of changes in the DNA, that it's mostly epigenetic. My guess is that the few mutations seen are random in nature but the epigenetic changes are shared across tissues throughout the body. Maybe another episode could be about how the epigenetic changes are triggered in the body? What signals are the cells responding to?
How do you go from 'we never entered space because space is technically 630,000 kms away now' to this 'space flight' within days? It was literally 2 videos ago.
Please like this so Seeker sees this, and answers.
Its the geocorona, its just hydrogen atoms bleeding off into space from earth. Its not atmosphere like your thinking as its pretty much a near perfect vaccuum. We are talking 70 hydrogen atoms per cubic centimeter. Im no expert but i hope this helped 😀
This video has more to do with the effects of the lack of gravity on the human body, due to being in low Earth orbit. Whether you consider that to be in space or not doesn't affect the results of weightlessness.
@Spartan 506 The air is so thin at that height that it is a near vacuum. The air pressure drops with altitude, until a near vacuum. But there still is a small amount of air, which is why satellites eventually slow down and fall back to Earth, unless they are boosted to a higher orbit, as happens on a regular basis with the ISS.
What do you mean by abstract matching accuracy??
Human papillomavirus, the cause of plantars warts and other related things. It would be really interesting to learn just how it hides from the immune system, which cells it makes its home in, and so on.
Yess this is one of my favorite viruses
Ive got the non sexual version. Caught it at the public pools after an event. Fucks me right off
@@ethank.6602 - I have an ex-gf who took terrible care of her feet. I used her shower frequently.
@@Omnifarious0 i prefer to go for hygenicly responsible women... but no i was in the pool with at least 200 other people and i assume the chlorine couldnt handle it.
@@ethank.6602 - She had mild cerebral palsy that made certain kinds of actions and movements difficult. So... Not really her fault.
And she was a very sweet person.
Can you cover Eosinophilic Esophagitis in your Sick series? I suffer from a very severe case that has almost killed me twice. I know a healthy amount about the condition but in-depth information is hard to come by.
Please cover Ehlers-Danlos Syndrome on 'Sick', it would really help spread awareness about connective tissue disorders
Great overview.
3:18 "Cognitive functions like emotion recognition decreased."
In microgravity, a frown is just an upside down smile. I wonder was this "emotion recognition test" biased by having all the faces oriented vertically ? Expose full time terrestrials for long enough to faces at different angles and their "emotion recognition" might also decrease.
Creutzfeldt-Jakob Disease would be interesting if you are gonna cover prions too :-)
I would also suggest rabies since it is the desease with highest mortality rate after the beginning of simptoms and since it has quite interasting effects on the body :-)
4:17 Scott! Have you been in space again!? You'll go blind if you keep doing that.
Do you have a podcast?
You guys should cover measles with the recent outbreak in New York, you would probably get more views and get some great info out there for people :)
The comment section will be filled with antivaxxers spouting conspiracies.
Hey Seeker,
A disease I am interested in Multiple Myeloma
I never fully understood how poison ivy affects our skin and how a skin condition from a plant can be spread from one person to another. I would love if Seeker explained it.
Maren has the perfect ASMR voice. Its soothing to the brain when I hear her speak....in addition to being informative. If she ever did a sleep ASMR, I bet it'll replace white noise.
But, how do we know how the human body will react being on the surface of Mars? Are there programs of thought underway for that question?
For Sick, you might want to get STIs out of the way early. Though I would like to see more coverage on chronic conditions especially age related and autoimmune issues. Alzheimer's, psoriasis, leprosy, and allergies are good places to start. More information about research and genetic treatments would be great.
Could decreased emotional recognition just be from the isolation?
That is what I thought
Please investigate what causes painful autoimmune illnesses, such as Myasthenia Gravis, Rheumatoid Arthritis, Lupus, Chronic Fatigue, and such.
Hi guys, I would love it if you covered Epilepsy. I personally have it and I would love to hear more about the scientific details of the condition.
So how much older than his twin is Scott supposed to be now from so much time in high speed space flight?
I would love to hear more about why mouth ulcers form, and some of the rare forms of those such as recurrent apthus ulcerations and the large formations of them that can scar mouths.
suggestion for "sick": non-alcoholic fatty liver disease. Dr. Robert Lustig thinks it is related to fructose. What is the current science on this?
You could talk about Karposi’s sarcoma associated herpesvirus (KSHV) for your new series SICK.
Or maybe mad-cow disease which is also very interesting.
In Sick, could you cover sunlight allergies? It would be cool to discover how it makes me itch.
suggestion - fungus and yeast in space. Given that closed environment the microbiota might be affected, possibly more dangerous?
I never knew someone could say *wreak havoc on our health* with such a big smile. This is why scientists are the best.
Human-bio studies is vital for optimized safety during space flight. Man is still working on the subatomic answer. I believe we got a molecular answer but maximizing is proving a little more difficult. Much love & big upps to Seeker for all efforts. Later Guys
So you can only spend so much time in space without permanent damage ?
We have a long way to go before setting up a permanent base on mars or even a long visit.
Mars is 40% earth gravity. People on earth weight 500lbs and walk around. So if u take a 180lb eather and do the math they would be 72lbs on mars. Add 60% weight on your body.
Building the muscle wont be a problem, they may be weaker but should be able to get around.
Only thing i can't specilate is the bone structure around the brain, will it affect anything?
Maybe spend time in decompression, a gravity increaser in orbit around the moon that slowly spins faster from 40% g to 100% g over a span of time say a month or more.. when ur body is adjusted and u come back to earth.
@@thesisko4031 thats alot of shit to keep functional. What im concerned about is that a moon or mars base would not be a place you can raise a family. Making it a place to visit, but not to stay. How long can you stay before it severely impacts your life.
We are talking years of exposure to low gav and constant radiation exposure. Of which we have little knowledge to work with.
I'd like to know how bedbugs affect our health and well being. And why there isn't a significant push to combat the infestations and problems with bedbugs. What is science doing about this very obvious and unpleasant situation?
Can you guys make a video on telomeres..?
The role telomeres play in ageing has been challenged. I think the theory states along the lines of misfiring of certain hormones that activate incorrect DNA. So like a liver cell might form in the brain which is obviously not what you want!
Cool video, very interesting.... @seeker For “Sick” can you cover virus induced encephalitis???
What does NASA do to help prevent the astronauts bones from weakening, when the astronauts are on long missions?
@Seeker - I'd love *"Sick"* to do a video on *prion* diseases, in particular *Creutzfeldt-Jakob disease.*
Though not a desease, pain is a Hugh medical problem. Things like our current opiate 'crisis ' ' dopamine deficit syndrome ' or Chronic Pain Syndrome lead to very real illnesses. The cost to society on a personal, social, economic levels is beyond calculating. So yeh...please do something on pain, perhaps ongoing research into drugs , therapies, etc. Thanx!!!
Do a “Sick” video on colds pls! Why do we still get the colds when we have memory cells and other phagocytes and cells that help “kill” the pathogens?
OMG they both look like Gru from Despicable Me
hey musiic name of balackground? bakground*
For your new show can you cover IBD aka Chrons and Ulcerative colitis?
hi i have a test on friday can you guys cover pseudopseudohypoparathyroidism. pls hurry.
I love this channel!
For your new series will you cover PANDAS/PANS?
Look at fibromyalgia and all aspects of its history and continued growth. We now know it's a central nervous system disorder but what does that actually mean. And why do women get it more than men?
Anyone know where I can buy that shirt?
#Seeker, can you make a video on the cause of and the actualities of ADHD, please?
So telomere length can go both ways? That’s huge news to me.
342 days! He was suppose to go for s year. What happened?
How about an episode on fibromyalgia?
No well-informed statistician will take the results of this study seriously. simple example:
Twin 1: N features were measured at M time points before and after leaving the earth.
Twin 2: N features were measured at M time points before and after twin 1 leaving the earth.
There are two problems:
1- The observations within each twin are not independent from each other (blood pressure from twin 1 at day 1 is not independent from the blood pressure of twin 1 day 100). There is a solution for that, we use what we call linear mixed models, these types of models can correct the dependence between the response variables using what we call random effects (I'm sure the great statisticians at NASA thought of that).
2- However the second problem is the objective of the study. Which is to demonstrate a difference between a person living in space for X period time, against, a person living on earth for X period of time. Here the fundamental experimental unit in the person/human, therefore in order to have a non-biased design of experiment, the fundamental unite must be randomized, in other words, a sample size of 2 is not the correct approach, even if we have multiple results from the two persons.., any significant results from the statistical tests cannot be taken into account, the power behind these tests are incredibly low when taking into account the experimental unit.
To be fair I can see why they did the analysis only with two people (twins, budget, experienced astronauts), however, to go and inference the finding of this on the whole population is a long long jump of faith and has nothing to do with science.
And also that no one left earth and he was in a Hollywood basement filming the movie like ISS footage such as the movie "Gravity" or "Interstellar".
I wonder how long it will take to put a ring out in space
Id like you to cover a superbacteria infection and possible solutions against them
Hello Seeker, never been this early to a video!
For your new series "Sick," please cover fibromyalgia! This "invisible illness" is SO misunderstood. Thanks!
2:50 - What if his telemeres increased in size because of his forced exercise routine on the ISS? In reverse, what if his exercise routine was less intense on earth? Maybe, could be, one cause - Right? We know exercise can extend life..
So basically space is NOT for us and never was. I mean how far do we have to go before we get the point or rather the hint?
Sure We didnt Evolve For it But We can still Explore it. We're omnivores and despite that we can an eat entirely plant based diet Just as an example.
can you cover how a stomach flu works in general?
Lyme disease.
Would like to find out more on this topic. Thanx
Stay tuned... 👀
So, what you're saying is that living in outer space will make me immortal. Excellent.
You should explain what the hell CWD is, because I want to know more about zombies
Wait what?
CWD - Deer zombies
What we need is a human born in space and raised in a controlled arena for the best tests
Regarding the telomeres its interesting people can live longer in space that means earths gravity might affect the way telomeres shorten/lengthen.
Seeker definitely has the best looking green-screen background colors.
Would love to hear you guys tackle Degenerative Nerve Disease.
ı have a question . it is not about this video . it is about quantum computers. ıf quantum processors need cold ( -273 celcius), why dont we built quantum computers in vacuum of space ? space is already so cold , ıt is just one problem up there it is radiation but here there are more problems , heat , magnetism and of course radiation and etc.
Why Maren Hunsberger looks like so much with Natasha Nice? Can Seeker Answer that?
