If we could induce hibernation in humans for long space journeys, what do you think would be the biggest challenge: preventing muscle atrophy, managing waste, or safely waking up after months of torpor?
Inducing hibernation in humans for long space journeys presents major challenges, particularly managing muscle atrophy. Reduced muscle use during hibernation can lead to significant loss of muscle mass. While some animals have adaptations to mitigate this, applying such mechanisms to humans would necessitate advanced therapies or rehabilitation upon waking. Waste management is another challenge, as the body's metabolism needs careful control to limit waste in a closed environment, possibly requiring innovative recycling solutions. Safely waking after months of hibernation is crucial, necessitating a smooth transition back to activity without negative effects, including preserving cognitive function and reorientation. Among these issues, muscle atrophy is the most critical, directly affecting readiness for tasks after waking and upon arrival at the destination. Addressing this is essential for the success and safety of long-duration space missions.
Roger this won't work, alternatively hibernation is like some of the medical situations on earth in some ways and in others not and is more realistic with the least expected risks. There's signal drift drift between the control and the receiver then there's interference from noise and a host of other things sought in the patients a nightmares or intrusive thoughts, yes there's a repressive code hot fix for it, but it doesn't deal with the correct choices by biology
Okay so my question is...... If all the planets are light years away and nothing can move faster than the speed of light.... Then how do these telescopes / satellites send and receive messages in such short periods of time..... That's unless I'm mistaken.. do like the satellites. Extend the range therefore increasing the rate at which the signals are received?.... And in the case of space travel, would it take years to get signals back from the crew on the spacecraft back to mission control on Earth?
Reference Dr Herman Pontzer. Evolutionary Anthropology, Duke University. Studies say something like this. Exercise doesn't burn more calories. Over time, you'll burn the same as no exercise. Your body works in the background to slow calorie burn for evolutionary purposes. I'm thinking this sounds a lot like what Ryan describes as torpor.
Hummingbirds are a good example of using torpor on a daily basis yet they can fly across the Gulf of Mexico in a single flight. They have an extreme physiology in such a tiny body.
@@fluffysharkdatazz9460 I have the flu and no food in the house, for the past week I ordered food. I feel that, I need to go out today and buy some water, chicken and potatoes. wish me luck.
Ryan is so good at explaining things, being super friendly and just an overall great guest!! Super interesting topic as well! Thank you for this episode!
Australian Plants bounce back from fires amazingly fast as soon as there is a period of rain. Nearly as fast as Deciduous trees sprout in spring. Many actually need fire to open seed pods and the seeds are spread floating in the updrafts from the fire. I believe I read once that some native grass even emit a flammable gas during fires so the air above them burns, leaving an inch un-burnt above the ground.
chuck is the perfect cohost and im always sad when he isnt on, gary is pretty good too and always puts WAY more research into the topic than either neil or chuck
Honestly I can't stop thinking about the medical benefits, if we can keep patients on transplant lists in torpor or surgery where the heart beats and moves blood slowly, that could be so huge for medicine!
Back Woods Hick. Retired Merchant Marine. Love your show. As a Sailor I read a lot. now that i'm on tera firma i'm trying to keep learning. As a sailor we used stars and the the sun for navigation. EVEN in this age of TECH. LOSE IT you better HAVE A BACK UP!
I know I still shouldn't give the squirrels in my yard too much peanut butter in general, but this make me feel better for spoiling them a little bit sometimes with two scoops lol
They did say that humans take energy from proteins and sugar first, while hibernating species use fat first. But seriously, why don't you just finish a video before commenting. It's not like you'll be the first to comment or something.
GREAT show! And you guys need to have on Jason Fung, Nephrologist, author of The Obesity Code and the Cancer Code! He's been helping people reverse Type II Diabetes for years using extended fasting (which is a metabolic disease, and is very related to this hibernation topic). And basically there's been great advancement in the health benefits of fasting, esp longer term fasting: past about 3 days Autophagy kicks in high gear which recycles proteins (damaged proteins and even cancer cells), Human Growth Hormone gets upregulated to spare muscle from being greatly diminished, Ketosis kicks in high which is the fuel source from burning the adipose tissue, and other metabolic functions... It seems like torpor is maybe an epigenetic adaptation related in some way to long periods of fasting (and interestingly seems to need to be proceeded by a period of massive feasting, like the squirrel example putting on 250% body mass before hibernation/torpor/prolonged fasting
The top minds of science and discovery . A fun episode . Really gets my imagination going about the possibility of deep space travel. The 60's got the moon landing , I would love a new space race , it strikes me as so unifying when we take on goals like that . I would never care which nation achieved it so long as we did . I have a high opinion of our species ability to conquer the unconquerable. Like Everest . I see mars as the new Everest . I'm dying to see a new moon landing. It seems when we study these things we find new things either way. Great brain food and inspiration. I remember watching Apollo 13 and what they had to do to survive to get home that's one of the many examples of what we can do .
Great episode! Really nice to hear when something that seems unrelated to you actually is impacting you all the time. Many thanks for all the insights!
I'm Spanish, we've been doing 'micro hibernations' daily for centuries. Also known as 'siesta'. It's a matter of survival, go try to work at 3pm with +35ºC outside and you'll understand.
Here's a question that I don't think was asked what effect does hibernation have on aging? Is aging exactly the same or is it slowed when in hibernation?
You'd want a longer journey than to Mars to risk it.... :) Also, hibernation wouldn't protect you from cosmic rays on its own, so you either need meters of low-density radiation shielding or a nice fast ship. Not much point in cryosleep/hibernation on a fast ship and short journey, but maybe an option for big interstellar ships one day. Efficient propellantless thrusters are the key to cracking crewed space travel!
Just a technical note, ROS have an 'exposed' oxygen ion, they do not react with oxygen, instead they are a molecule or even atom (singlet oxygen) with a reactive oxygen ion. Also fat is stored water 100 g fat will generate about 110 g water if all the fat is metabolized.
Awesome ep guys thank you to our guest again. Man ... I'm gonna go to sleep tonight thinking about this one! I wonder the mind games the animals play in prep for hibernation. I believe animal in the wild is capable of much better decision making in the sense that it's less distracted and has a clearer understanding of what it is they must do. So deep thought/meditation etc will be key in this endeavor... Alot of research and alot of pondering to do there
Thank you, gentlemen. An excellent conversation. Fascinating what humanity's future may hold. I are intrigued 10 hear of Fauna Bio and Eli Lilly's collaboration on meds for obesity. I started on Mournjaro to help with Diabetes in January. my A1C is now at 5.1 and I have last 42 Lbs. Ihope you are able to develop more safe drugs to help us all. 💙🌻💙
Unlocking the ability to hibernate, has some interesting possibilities...like, turning up at the office, after vanishing for three months. Sorry boss, I slept in...
One way to stave off food consumption and therefore need to bring less food is to have all the astronauts on Mounjaro or similar drug. Then they can eat the small amounts of daily protein and vitamin needs without feeling hungry. These drugs have an appetite suppressant which can be very helpful as well.
I was hoping they'd say something about airline stowaways and the 1 in 5 who survive flights in the wheel well. One article said it's a hibernation-like state for some, but not true hibernation. This is a fascinating episode and great discussion. I'd love to volunteer for a study!
Since we can induce comas, medically, it makes sense to me to do that, have them turning in a small centrifuge to impart some gravity on them continuously and fed intravenously. They could also have their muscles exercised electrically to keep them in a reasonable bit of shape. One person would be awake at a time (maybe two depending on how many are going) to keep an eye on things and maybe switch every few weeks.
I'd go see a Pixar film about animals from outer space showing up here too " Hey Stitch!" Great video you guys. Had no idea that creatures could hibernate in the heat too.! Fascinating ...may our species be successful in it's endeavours!
Without a selective pressure, there can be no natural selection. Animals in the wild are not exposed to extreme levels of gamma rays. If there is some sort of association between torpor and radiation resistance, there could be some unexpected connection between the two, and that's what is interesting.
I heard that bears actually get up, move and breastfeed during their hibernation. That could be the answer toward humans for humans to prevent muscle hypertrophy. I think our torpor cycle would be 2-3 days or torpor + 4-8 hours of sleep.
Mom had some strokes, n sleeps many hrs a day, always tired, do you think oxygen deprevation, or is some of that her body teying to sleep for longevity
Maybe one of the things genetically modified humans on Mars should be able to do is hibernate. So when food is low people can go to sleep instead of starving to death.
If prisoners are asleep for the full sentence what’s the deterrent effect and rehabilitation period. Which is what makes up any sentence. First the deterrence then the rehabilitation period. If they are just sleeping they are not really doing the sentence at all. A 3 year for example sentence includes 18 month deterrent and 18 month rehabilitation period. They need rehabilitation or will not only reoffend but the seriousness of the offences also increase. I studied both Criminal Justice and Social Policy. The prisoner needs to know and take part in both the punishment and attempted rehabilitation. I say attempted because not all prisoners will take part in rehabilitation. Only punishment then works. The sentence, remand period is also used to protect the public from the worst or constant offenders. I live in a country that has no death penalty. We give out life terms to the worst. Some are so serious and dangerous they can never be released. I would use your method on lifers who take part fully in their rehabilitation. Take part in rehabilitation and earn periods of hibernation. It would benefit both the prisoner and the prison and justice system. It could work but needs a lot of research and technology to get there. Interesting though. Have a good day.
Interesting topics. My mind went immediately to the film Pitch Black with Vin Diesel and then immediately jumped to Superman when they put General Zod and his cronies in the Phantom Zone
I think for that long of a trip we need to be able to simulate gravity, which should also help with getting hibernation to work on the trip to Mars. I thought we could simply do it by accelerating the spacecraft for half the trip, doing a flip maneuver, then decelerating for the last half of the trip.
Great topic! You discussed muscle atrophy, but what about bone loss? This is already a problem in space, but longer term and with no stress on the bones while we're out, how do we not break all our bones after we try to do anything when coming out of torpor?
Fats, carbs, etc often have an -H or -OH at one end of the molecule chain. Sometimes these can be hydrolyzed into water (H + OH = H2O). I'm not sure if that is used during hibernation though, or if it is only something a few desert animals like camels and kangaroo rats can do at a meaningful level. Might be worth asking about if there is a follow up episode.
Hibernation seems more like a slower wake state rather than a sleep state, if the animals gets out of hibernation for a short period of time just to go to sleep? If so, has there been studies of deep meditation being more like a type of hibernation? Are there like some amazing monks out there that can hibernate more than others who normally meditate? :)
When you go to hospital, they put you to sleep, is thst somekind of hybernation?, how long can they keep that sleep? Can thst be a substitution for hybernation.
Interesting episode. Are there any studies done to see the effects of radiation other than gamma rays on hibernating animals? In space there are other forms of damaging radiations like alpha/Beta particles, X-Rays, UV -Rays etc. Specially alpha particles have enough energy to physically tear the DNA strands. So even in hibernation/torpor, when the metabolism is almost ceased, alpha rays can still severely damage DNA. So when the animal wakes up it might feel the effects of this kind of damage.
if torpor becomes a thing for long periods of time and assuming that while in that state we delay our natural decay, we could live for a few hundred years. we would come out for a couple years just to see how things are going xD
When I was a young lad if I sprained an ankle or something I would go home an sleep till next day. At 43 I feel off a roof spent 1 week in intensive care. Sleep the whole time when they finally moved me they said they usually have to sedate people to get them to sleep so long.
I saw a wildlife show and in that show there was a lizard in Africa that everywhere thru the dry season this lizard would dig down, bury themselves in the dirt and hibernate until the 1st rain several months later

Well now you can
If you went into torpor in 1965 and woke up today, it would have felt like 600 years.

I'd imagine you age normally or perhaps the tiniest bit faster because the body is at a constant standstill, unless you figure out cryosleep.
I think you age as per the speed of metabolism. If your metabolism is slow, you age slower. 👍
Always a welcome notification.

i was in a coma for 3 weeks. i lost 60lbs in muscle mass being a veggie. it sucked. if you want to ask me more questions have at it hoss.
Do you recall ANYTHING? Or was it like going to sleep and waking up?
Deer eat grass which exists all year around. Bears eat seasonal berries and other fruit & vegetables, so hybernation makes sense.

It seems like unlocking the ability to burn fat instead of muscle would be enough to make your company filthy rich.
Torpor might also be very useful in medicine, by slowing down things like cancer growth until it can be affectively be treated.
Summertime torpor is called aestivation (a word I learned in high school biology many years ago) and not hibernation.
A fascinating video. Thank you
Please make more videos related to Mars
Ryan Sprenger sounds exactly like Rob Lowe, now that i've said it you'll never unhear it.
"No reason why hibernating species are more resistent to radiation"
Well, that would be natural selection 101...
Without a selective pressure, there can be no natural selection. Animals in the wild are not exposed to extreme levels of gamma rays. If there is some sort of association between torpor and radiation resistance, there could be some unexpected connection between the two, and that's what is interesting.
This was so fun and interesting to watch and listen to!
Thanks for expanding our horizon of knowledge!
Great conversation. Enjoyed this one.
How was love watching Star talk
I heard that bears actually get up, move and breastfeed during their hibernation. That could be the answer toward humans for humans to prevent muscle hypertrophy.
I think our torpor cycle would be 2-3 days or torpor + 4-8 hours of sleep.

OH THIS EPISODE IS GONNA BE BUSSIN! IMA PURSUE MY DEGREE IN PHYSICSS!!!!
I think for that long of a trip we need to be able to simulate gravity, which should also help with getting hibernation to work on the trip to Mars. I thought we could simply do it by accelerating the spacecraft for half the trip, doing a flip maneuver, then decelerating for the last half of the trip.

Is dreaming while hibernating happens? Would that use extra amount of calories?
Why not get to Mars way faster ? Why not park some solid rocket boosters in orbit ? And park some ahead of time in Mars orbit for the trip home.

2 Questions, What do Hibernators do about Waste ? Also how low does the Blood o2 level go ?
I wonder if hibernating animals live longer?
Muscles do not atrophy during sleep, the stiffness of movements and the brain does, everything relaxes in sleep!
Hypothalamus is also circadian rhythm control system
Interesting episode. Are there any studies done to see the effects of radiation other than gamma rays on hibernating animals? In space there are other forms of damaging radiations like alpha/Beta particles, X-Rays, UV -Rays etc. Specially alpha particles have enough energy to physically tear the DNA strands. So even in hibernation/torpor, when the metabolism is almost ceased, alpha rays can still severely damage DNA. So when the animal wakes up it might feel the effects of this kind of damage.
The implications could be very important for us on earth as well as out in space.
Some of their protection from radiation definitely comes from not participating in the food chain during torpor and cycling out of it regularly
Hibernating Bears in Space is my fav movie
The sequel "Grumpy Bears from Space" is even better! ;)
if torpor becomes a thing for long periods of time and assuming that while in that state we delay our natural decay, we could live for a few hundred years. we would come out for a couple years just to see how things are going xD
"They love their abbreviations" -Bob
Does radiation effect cells like; an EMP on a circuit?. The less active the cell, the less it's affected?

I'm envisioning an exhibit at the Smithsonian's Bear-in-Space Museum :)
Oh boy, the future will be wild!
