EDIT 2020 Update: I've now grown actual spider silk. At time of writing, I'm about to grow 5 gallons of the stuff in the next couple days. Here's the update video th-cam.com/video/2hf9yN-oBV4/w-d-xo.html Couple of things. First the idea we don't know enough isn't really accurate and there are growing numbers of groups who've succesfully made silk on par with the natural varieties. It's pretty straight forward "make the proteins longer". Successful groups add linkers to the ends of the silk genes so that once the individual proteins are produced they stick together in a special way that makes the fibers much longer and stronger. Little bit of protein engineering goes a long way if you've got a fiber gene to work with. That said, silk is a weird protein that is very repetitive and who's gene sequence is GC rich. This makes it hard to isolate from spiders and transfer to a new organism. So most people make their own DNA sequences that are easy to synthesize, who's protein, while having a lot of the same properties can be inferior for a variety of reasons. This is less of a limit of knowledge and more a limit of print capability. We're limited in the patterns the machine can handle. Our synthesis technology can't print this gene, so we have to massively simplify it and keep it short and repetitive to save on cost. But also even if you print the gene, super long proteins are hard to grow in ecoli at a scale that's useful. They literally get filled up like balloons and stop working, but also that repetitive nature drains the cells supplies of alanine and glycine. So yields are awful even if your fiber is amazing. Doesn't matter if it's better than the real thing if your organism produces miligrams per gallon of media. Hence the weird organism choices like goats. TL:DR use natural silk genes if possible, add linkers to the end, pick a bigger organism than ecoli, then just use special solvents to dissolve and wet spin fibers. Tada you've got silk on par with the real thing if you choose all the right things. And there are some pretty decent guidelines on what to pick as lots of people have made silks of all sorts of varieties. So it's not that we don't know enough per say. It's more that our technology has some weird and specific limits that makes this a hard problem to physically make happen in a lab. Even if you design a perfect fiber, actually moving the small volumes of liquid around in the right way and having the reactions and organism work as planned is the limiting agent as sometimes bio just wont play along. The spinnertte thing is largely irrelevant and there's half a dozen ways that all work just as well. It's a really weird biochemistry lab problem more than anything. I obviously had to glaze over some stuff, but that's the gist. For those interested, I'm actually working on producing a yeast that produces spider silk and am documenting and explaining the whole process on my channel. Rather than synthesis I'm attempting to extract the genes from spiders so I can have a more natural fiber with less human/synthesis error in it: th-cam.com/video/Fx8TcGrCOSI/w-d-xo.html
@@quadeevans6484 they talked about it in the video. Spiders have specialized organs that process the silk proteins, and that's harder to transfer. There's a TH-cam channel where someone got yeast to produce a primitive form of spider silk called Thought Emporium, but the problem is that spiders produce multiple forms of silk depending on their needs. These varieties require a large genetic capacity, which requires large batches of DNA made of small and precise repeating sections of genetic code. Combine that with the supporting genetic code for other traits that make effective spider silk, and you end up with something that is specific to what a particular species can support. EDIT: looks like that guy from the TH-cam channel I mentioned is in this comment section too. He's right below this comment if you scroll down a bit.

I'm surprised you didn't reference the gold orb weaver cloth on display in the American museum of natural history in New York City. It's an 11X4 ft cloth made from pure gold orb weaver spider silk and is probably the most expensive piece of cloth in the world considering it took 4 years and a MILLION spiders to make.
yes but its impractical and spider is not a social speciment (not entirely though there are social spiders) However its very difficult and impractical to make a ball of spider silk buy just collecting silk.....search silk DNA instead

Yeah, why don't they? Maybe they just have to invent some Vacuum Collector and instead of us buying new bags, they buy our filled bags. Then make a tie out of it and sell it back for 1000x the money
"We have to not only figure out a way to replicate the dope, we also have to find a way to spin it." That's 100% talking about making and selling illegal drugs.

If they think theres bacteria in the dope, couldn't they stick it in petri dish and incubate the bacteria to get more? (I truly don't know if it's that easy aha)
Now now, don't hate on golden orb weavers too much. They aren't all that aggressive, even if they are somewhat intimidating because of their size. I am no fan of spiders, but I had a golden orb weaver that made her home in my screen door for three years - and then one of her daughters took the spot for another year. There was no screen cloth in the door: but thanks to the spider I could leave the door open in the evenings anyway! Worked out great for both parties. She never got upset at us for opening or shutting the door, just hung out and did her spider thing. It's no surprise really that science hasn't nailed down how to make the exact silk, but it's fascinating research and well worth the effort even if we never manage spider-silk bridge cables.

Organon there are actually two of them. If that’s what you mean. In fact there’s also muscle hank, a clone that kinda got messed up in the gene area and got way too jacked.
Look up "Goats that produce spider silk." They have goats which have the spider silk protein in their milk. The story I found was dated 2010 and there is another, more recently, which talks of separating the spider silk protein and making it into fibers which can then be woven. The original goal, as I understand it, was to make bullet proof vests.
About the spiders not being social or so territorial that they eat each other, you guys did post a video a while ago that featured a species of spider that are social (like hundreds strong) so they can make a LOTS of webbing and probably not take up a huge amount of space like those that aren't social. It might not be Golden Orb Weaver strength, but i think its a great start!

Is spider silk really as strong as steel? I have always heard this fact repeated but I have never seen any kind of experiment or proof to show that it is true.
That notion's truth is in the density/mechanical properties proportions. If you were to have a line of steel the size of a line of spider silk (smaller than a human hair), you will see that the spider silk is more robust. www.ncbi.nlm.nih.gov/pmc/articles/PMC2658765/ Table 1 in this article gives a nice outline of what I just said.
It has a greather tensile strength per unit weight, steel does better when comparing cross section. It really does have some great properties but it is a shame it is so often glossed over as stronger then steel. They have done controlled tension failure tests on it in materials labs and you can actually find its Yonng's modulus, maximum elongation and yeild strength for the silk of several different species of spider.
It is. What people forget to mention though, that it is stronger than a steel rod _of the same diameter._ Which is usually a thousandth of a millimeter...
@@DarthBiomech Its stronger then a rod of steel the same mass, by diameter steel is actually stronger. The strength measurement in table 1 linked by @Naude shows that where the breaking strength of spider silk is 1.1 GPa and steel is 1.5 GPa. They both lose to kevlar and carbon nano tubes at 3.6 GPa and 4 GPa respectively
Yes, as a strand/wire of the same size. As spider silk (S from now on) does not generally exist in larger sizes, it's a silly comparison. I have not read about S being manipulated into complex structures as practical material sciences is all about, nor have I read of S even being woven into simple rope beyond the earliest of experiments. If you're thinking of being on the cutting edge of science, you can study this. ;)
there are some social spiders that build enormous webs that sometimes reach across rivers that has enough trees to allow so. the silk they produce should be looked upon.
great video. add to that that only recently we know the total sequence of these spiders and we havent event scratch the surface of the components of the silk, which in conjunction synergistic. Also, just think the same spider making the dragline and the properties varies quite a lot. So we have bio-inspiered materials but not silk.
Andy Lewis, the scientist who pioneered the "Spider Goats" was the director of the Biochemistry department at the University of Wyoming when I studied there.
@@MariaMartinez-researcher actually the ones that made colonies in Greece or everywhere else are not communal but the conditions made them to act as communal because of the amount of mosquitoes they found and multiplied in huge numbers (tetragnatha spiders spp was the spider - i am from Greece) .

There are many communal spiders but still its very difficult to analyse the web and its totally impractical to gather it to produce silk as we now it.

Spiders (and other arthropods) that can do this don't gain the ability from their body structure. They get it from being small. The smaller you are, the less falling from a great height matters.
Spiders V. Tasers= you only make a stronger and more highly agitated arachnid with electro-magnetic discharge capabilities what can spin webs to capture you then taunts you as it jumps up and down on your face
The Worm web serial by Wildbow goes into spider silk's uses fairly deeply; the story's main character makes her suit out of the stuff, and as a result it's both bullet resistant and stabproof. She's also goddamn terrifying.

Wow. It makes Peter Parker seem a bit selfish. He worked all that stuff out by himself, and didn’t share that information. Of course, if he did, villains could use it for evil.
when saying evil in relation to super villains you're supposed to hyphenate the word for emphasis as in
E-VIL followed by many exclamation marks!!!!!!! comic book cannon...works in real life as well
I have definitely thought of a cobweb article of clothing after knocking a spider web away, that’s why I’m here, lol
Is spider silk really as strong as steel? I have always heard this fact repeated but I have never seen any kind of experiment or proof to show that it is true.
That notion's truth is in the density/mechanical properties proportions. If you were to have a line of steel the size of a line of spider silk (smaller than a human hair), you will see that the spider silk is more robust. www.ncbi.nlm.nih.gov/pmc/articles/PMC2658765/ Table 1 in this article gives a nice outline of what I just said.
It has a greather tensile strength per unit weight, steel does better when comparing cross section. It really does have some great properties but it is a shame it is so often glossed over as stronger then steel. They have done controlled tension failure tests on it in materials labs and you can actually find its Yonng's modulus, maximum elongation and yeild strength for the silk of several different species of spider.
It is. What people forget to mention though, that it is stronger than a steel rod _of the same diameter._ Which is usually a thousandth of a millimeter...
@@DarthBiomech Its stronger then a rod of steel the same mass, by diameter steel is actually stronger. The strength measurement in table 1 linked by @Naude shows that where the breaking strength of spider silk is 1.1 GPa and steel is 1.5 GPa. They both lose to kevlar and carbon nano tubes at 3.6 GPa and 4 GPa respectively
Yes, as a strand/wire of the same size. As spider silk (S from now on) does not generally exist in larger sizes, it's a silly comparison.
I have not read about S being manipulated into complex structures as practical material sciences is all about, nor have I read of S even being woven into simple rope beyond the earliest of experiments.
If you're thinking of being on the cutting edge of science, you can study this. ;)
there are some social spiders that build enormous webs that sometimes reach across rivers that has enough trees to allow so.
the silk they produce should be looked upon.
Pretty sure we can't make human hair either, but we probably haven't tried as hard.
Funnily enough I was thinking about this same thing, lol
Well, we have humans to make human hair for us. They're pretty good at it, so there's no real reason to engineer a different system.
@@wasd____ damn hippies
great video. add to that that only recently we know the total sequence of these spiders and we havent event scratch the surface of the components of the silk, which in conjunction synergistic. Also, just think the same spider making the dragline and the properties varies quite a lot. So we have bio-inspiered materials but not silk.
All we have to do is make some DOPE! XD
Bridge cables, airplanes and biodegradable bottles. I wouldn't want anything structural made from biodegradable materials.
1:04 Well I'm not sleeping tonight...
Did anyone else get the heebee jeebees watching that spider slowly inch closer and closer to the sleeping person?
Laughs in Thought Emporium
2:12 That's *DOPE* (pun intended).
*The Thought Emporium has entered the chat*
Totally rekt XD
Andy Lewis, the scientist who pioneered the "Spider Goats" was the director of the Biochemistry department at the University of Wyoming when I studied there.
The thought emporium is close (TH-cam)
1:02 Ooookay, thanks for the nightmares tonight SciShow!!
_If you shave a Spider do you get wool?_
If only spiders lived in colonies, like other invertebrates...
_Wait that's a bad idea._
*There are spiders who live in colonies and pictures showing them covering in cobwebs trees and stuff* in Greece, Brazil, Australia...
@@MariaMartinez-researcher Wow. Thanks for that.
@@MariaMartinez-researcher actually the ones that made colonies in Greece or everywhere else are not communal but the conditions made them to act as communal because of the amount of mosquitoes they found and multiplied in huge numbers (tetragnatha spiders spp was the spider - i am from Greece) . However communal spider are anelosimus eximius in tropics (no dangerous) / agelena consociata etc... There are many communal spiders but still its very difficult to analyse the web and its totally impractical to gather it to produce silk as we now it.
@@gfanarakos (You have just added another layer to our nightmares... spiders that just acting by themselves create those huge webs, and spiders that do act as a community. Next step, all spiders acting in consort to dominate Earth, while humans run in terror... while screaming their scientific names!)
@@MariaMartinez-researcher that actually happened last september...check its natural and than god it happened cause people there could not get out beacuse of moquitoes... dont fool yourself with jokes... learning is the key .... th-cam.com/video/my7mk2bVJz0/w-d-xo.html
By the way there is a museum with a spider silk blanket made from the goat milk, they allow people to try and tear it as well :D
I just watched a guy make silk
I once did exactly that in Dwarf Fortress. Captured a giant spider and farmed its webs so I can make spidersilk socks.
Why don’t scientists try to biologically engineer ourselves to have stronger bones.
So we jump of tall things without breaking our legs.
Ethical implications and limitations with DNA editing technology
Have fun with those g forces of sudden deceleration bruh.
Stronger bones means less flexibility. Usually bones don't break for being not strong enough but for not being flexible enough.
@D4RKplayz What are you, Finnish?
Spiders (and other arthropods) that can do this don't gain the ability from their body structure. They get it from being small. The smaller you are, the less falling from a great height matters.
The dragline silk troll was 👌
Because we aren't spiders, duh
the idea seems pretty dope
Was it *really* necessary to show a spider creeping down towards a sleeping person's head..?
Yes
Yes. Yes it was.
Yes. Very necessary.
LOL. Someone had fun writing the line at 1:04. Now I can't sleep...
Hank, I think you get pleasure from freaking people out! Spiders on our faces! Argh!
Spiders V. Tasers= you only make a stronger and more highly agitated arachnid with electro-magnetic discharge capabilities what can spin webs to capture you then taunts you as it jumps up and down on your face
DOPE video
Quite the liquid crystalline solution
Try telling this to the Thought Emporium

Well this aged poorly
The Worm web serial by Wildbow goes into spider silk's uses fairly deeply; the story's main character makes her suit out of the stuff, and as a result it's both bullet resistant and stabproof. She's also goddamn terrifying.
This is the content I love
That's why Spiderman had a hard time to make spider silk
thanks for the reminder of one of my favorite villains ever!...oddly underwhelming video for such an interesting topic though.
I always wondered why my little spiders in the corners on my bathroom would one day, always end up eating each other.
That's dope, literally.
Thanks. I have been wondering on why we don't use spider webs for doing stuff for a few decades. It is such a crazy unique material.
This video was DOPE yo. Also insert any and all DOPE jokes here.
Was I the only one dying of laughter whenever he said dope
