“How does the limb know how much needs to be regrown, how does it know when to stop growing?” I mean, how does it know how to grow the limb the first time?
Our genetic coding in our DNA. We are miles of information turning chemicals into cells into bodies; here to see it but never to understand it. Don't look further.
I hope we figure out how to regrow limbs soon I wish we would invest more in stem cell research especially now that we know it can come from bone As someone with cerebral palsy it would be very helpful
Well, I mean there's *Some* progression right?. A guy that got his manhood injured, had to attach some sort of meat thing to his arms to regrow a new one and then have surgery to attach it to his crotch.
Yep, i honestly feel like there has to be some conspiracy here. Like we have this technology, we know it can come from safe and ethical sources, we know it can do magic to cure all sorts of diseases and even help with cosmetic stuff, and yet we just have the ''research is still ongoing'' thing that yields nothing
That’s the next thing because if ppl that lose limbs experience a phantom limb. Maybe the brain doesn’t even fully register that the limb is gone. So why would it try to regenerate something that is still there
I mean we technically do. Medicine and Surgical advancements have drastically increased the average age of death. Back in medieval times, you would be lucky to reach even 50.
I would love full regeneration. But it would probably cost to much energy and increase the risk of cancer, since modern humans have a very unstable genome.
I think it would probably make just as much sense to focus on the mechanism in human fingertips. Those don't overgrow either after all. Would be amazing if it could ever be used to regrow a full arm.
This limbs regenerations will make people that are born without limbs and people that are amputated lives a lot more better. I still hope it happens cause for their sake and I hope Kiersten Kelly would get that treatment like that for her missing arm that she was born without. I kinda a big fan of her despite voicing Brooklyn from Jurassic World Chaos Theory. If and when she gets that limb regeneration treatment she’ll be happy and more better.
It's said that sea stars/starfishes (i'd call coast stars) regenerate when they were cut in a few pieces, so they would be defined as some kind of zombi creatures (lacking a mass brain whilst sneaking away from potential danger), and some crabs or similar species also regenerate a scissor or plier if that limb part got lost. Or look a some beetles or bugs that move again after gotten freezed.
I belive if something small of this nature could be discovered it may be extremely useful to people suffering from awful forms of cancer. Something as simple as the body being able to regrow in damaged cancerous areas of skin or flesh.Very cool concept!😊
SALAMANDER: We will not tell our secret. We've seen what happens if you have our regenerative ability SCIENTIST: You've watched the Hulk and Deadpool movies,huh?
No you’d be a sorry son of a daughter who has to wait a couple of years to grow his limb back and half of that time for it to regain full functionality. That’s if you don’t bleed out.
I once had a dream in which I could talk to my body in an out of body experience, I asked him why can't we grow back limbs or be immortal, he said because we're supposed to die in our due time, its for the better. I still think growing back limbs would be cool, specially hands.
Another good topic would some explanation about what does it mean for cell to be old and what it mean to be old as multicellular organism. Looks like we know symptoms of being old but not the reason of it.
I recommend Michael Levin lab’s field of study. They are already making huge steps toward limb and organ regrow therapies for our brighter future. It’s not in the near future though.
I think we can't grow limbs due to the existence of bones. The calcium deposits required to completely re-establish a limb is a lot more than the tip of fingers or axolot limbs
The idea of humans re-growing lost limbs actually gave me an excellent idea for a series of written works. Imagine in the far future humans have the capability to fully transplant someone's entire brain construct into a new body. Weirdly enough, the body is the recipient and the brain system component is the donor... thing. This would be such a time in the future where 90% of the complications involving nerve connection/re-connection limitations and other complications have been solved and streamlined. Medical science is so advanced that we could even do this with a mechanical chassis and someone could live as a cyborg, mostly machine, but the human component is what drives the ship. So many questions to answer. How long can one's brain age even if the body is ready to die? Could old work with the new? Since hormones primarily affect bodily changes, does that mean a brain from one gender would simply work under the conditions of the other gendered body whilst subjective to the hormonal wirework of that new body? Will the former David now be able to give birth? We have to keep in mind so many things about genetics that from a network of on/off signals to even developmental deprivation (on purpose), a future where humans could reattain a lost physical capability seems so far-fetched and impossible. So much so that any attempt to advance it will only develop and uncover a plethora of problems not originally foreseen. This isn't like the movie Robocop.
It’s insane that such a complex and intricate procedure is performed sentiently. I can barely understand how this works genetically, yet the body can construct it perfectly without thinking. God is truly a masterful architect for creating such an advanced mechanism to house our souls
I was actually wondering why some animals are able to do this and most can't. It even starts with the regeneration of teeth, compare sharks with humans or many other mammals. We get a new set of teeth once in the childhood, but not a 3rd time ... why is that so? :/
Humans can recover from broken bones but that hasn’t caused too much of an issue, though including the speed of the recovery I’d imagine most dangerous weopons would be taken much less quickly.

Stem cells. We have it. We used it. Yet lizard gets to regenerate limbs. Truly a skill issue.
I imagine those lizards look at us and think, “Get good, noobs!”
We need to lv up our skill set
We couldve probably have it researched by now if we didnt have a wierd scientific obsession with only researching the uncool stuff
Salamanders are not lizards. They don't have scales, and are not reptiles.
If we didn't such strict ethical laws in place restricting scientific pursuit we probably would have figured out how to regenerate limbs by now.
I wish I could regrow the brain tissue I have lost due to social media

You still have the neurons, they are just in standby mode because they have been unused for a very loooong time so they are saving energy.😂😂😂

Mine as well, but nothing of value was lost 😅
Axolotls are amazing. I don't know if we'll ever learn how to regrow human limbs, but that would be incredible if we could.
I’ll take a regrown tooth 😅
If I were a millionaire, I'd donate my entire fortune to research for this.
@nerdlingeeksly5192
Honestly same. I'd spend my money trying to cure cancer too
I believe we will (I'll be long dead probably).
Will definetely be possible in 40 years, not on a consumer-level but im sure it will exist. There will be so many new technologies that we now can never even think of needing
I’m sure discovering how to be able to do this with human limbs would cost an arm and a leg.
**sigh**
Are you proud of yourself
Was it worth it?
Literally 😂
Nice pun
If only we could! Would lead to some pretty unusual Guinness World Records however. 'Most Legs Regrown'.
You should watch the 2011 national geographic documentary "how to build a beating heart"
We could maybe but then who would spend money on missiles and nukes
I see, Spider-man writers got Curt Connors totally wrong. He was researching the wrong animal and should turn into the Salamander, not the Lizard!

Either way if he messed up .. He Will become The Salamander

Its same as asking why elephants or whales don’t just regenerate their whole limb

Very cool comment. Maybe it’s a topic of neuroscience combined with the muscular and skeletal and nervous systems
I mean they already said it in the video. There is no point being able to regrow limbs if we (or our cells) don’t know how to notice a missing limb
I heard an Octopus can regrow lost tentacles.
Infinite takoyaki...
thats why they are aliens 👽
"We are losing this ability more and more every day because we've abandoned living in nature."
Since the nervous system of octopus is their brain, one could argue they're regrowing their brains.
@@evanrosman9226 yes, the eight tails can easily regrow its tails.
Last week I found out that Japanese scientists found a way to regrow teeth in humans by unblocking the proteins and now this, science is just amazing!
Junho would be proud
That’s great now let’s hope they find a way to regrow lost limbs.
Perfect video for my incoming examination!! 💗
This channel always knows how to take fascinating subjects and making them accessible and understandable

What is amazing is the new limb is the one lost, not a wrong body part.

Hi Ted ed
Awesome video.
This topic recently I dreamed of and asked question myself.
What a coincidence,you posted video.
Thanks for answering.
If we master this technique we can technically de-age ourselves.
I think that would be so bad
I mean we technically do. Medicine and Surgical advancements have drastically increased the average age of death.
Back in medieval times, you would be lucky to reach even 50.
Not really, salamanders aren't immortal.
I would love full regeneration.
But it would probably cost to much energy and increase the risk of cancer, since modern humans have a very unstable genome.
That's how Piccolo regrows his limbs.

That's gotta be a key to deal with cancer in better ways
We gotta upgrade our skill tree a lil bit more to get that skill
Hopefully regeneration will come soon!
Great video 👍
Great video
A Spider-man villian did the same research, but with lizards.

Kinda cool seeing what could be what Dr. Conner's goes for in Spider-Man comics besides just "Lizard DNA = New Arm."
Spiny mice do that too? Seems like they should study them the most for possible human applications. Exciting time to be alive! Go crispr!
very wonderful

SALAMANDER: We will not tell our secret. We've seen what happens if you have our regenerative ability

Or The Lizard from Spectacular Spider Man.

This is interesting to know
It's amazing how a baby grows and develops innthe womb 😄

Amazing
I wanna know about starfish and flatworms that when cut regrow into different organisms, basically multiplying.
So cool
Developers thought humans were way too overpowered with their intelligence, so they decided to nerf our regeneration.
Forgot to mention leopard gecko, anole, iguana tails. Im curious why crested gecko tails are different
Salamanders must be in a lot of dangerous fights or accidents to need to regrow limbs.
The amount of food we'd have to eat for 6 weeks in order to regrow an arm...
Imagine regrowing your brain, will you forget all the movies you have watched? 😅

Wonder if brain cells and organ cells can also be regrown, if we can master that then immortality is achieved.
Does having high durability beat regeneration? You can't heal if you never take damage. And you can't take damage if you were never scratched?
Humans can recover from broken bones but that hasn’t caused too much of an issue, though including the speed of the recovery I’d imagine most dangerous weopons would be taken much less quickly.
Magic
I wonder what would happen if you transfer the blastoma to a different part of the body.
Because we haven't figured out how to use reversed curse technique yet
If I can regenerate:
