What is a woman? I dare you to answer that in your videos!
@@uabir8338 what a stupid question, like literally everybody doesn’t already know or have the answer told to them by their conscience. Conscience? Con? As in “Against”? And science as in “Science”? Why should he answer that question when everyone who can understand him already knows the answer? What do you think is one of the first things babies ask about when they learn how to talk? You will find that babies speak because they want to say something not only because they want to know something.what they have to say is usually their own understanding of what a man/woman is. You ain’t never had no body try to tell you what a man or woman was like you didn’t already know? If you can understand me then stop your BS.
Spiders won WWI and WWII.
My friends grandpa worked as a silk harvester during WWII. He would take a spider, mount it on a special harness and stimulate it to produce silk. He would gather the silk, winding it on tiny cards until the spider could no longer produce. Then that spider would have a vacation for a few days to recover before another milking. He was responsible for thousands of spiders and kept them in rotation.
How did they win WWI and WWII?
The silk was used as the cosshairs in every bombsight, artillery, firing scopes, gun scopes, spotting scopes, anything that required crosshairs, reticles, collimated reticles.
Can you guess what kind of spider was best?
The Brown Recluse.
There's a RUclipsr named "the thought emporium" with a background in genetic engineering that genetically engineered yeast to produce spider silk! He showed the whole process, and documentation. And an earlier group developed goats that produced the silk from their mammary glands which turned out to be somewhat impractical for mass production. The "spider beer" has some real mass production potential as yeast reproduce rapidly.
ohhh damn I love this. I want a shirt made out of it. I also kind of want to drink some spiderbeer tbh too.
this guy literally cured lactose intolerance for himself
madlad is on a mission
@@raezad if I remember correctly he hasn't even completed his degree in genetic engineering and made that gene therapy treatment pretty early on in his education. Truly a madlad.
@@coryshannon449 The guy is a true genius who inspired me a lot! I'm also studying Biotech & Genetic engineering. I hope one day I get to meet the guy. I genuinely wanna meet him face to face more than most celebrities.
Well recently I have looked up the research on that topic and found a article (from 2014) with and interview with a scientist that formed AMSilk (a German company) how they did it ( short and basic explanation of the concept) from spider to coli bacteria (instead of yeast because of the genetic reasons maby better product) and how they spin the protein in to thin threads 10 nm as smallest and how the production of the protein is already scaled up and companys have build prototypes for same applications (vacuum cleaner bags, running boots and so on) but they don't publish a product with the material (beside same cosmetic that uses the protein but not threads or fabric)
Imagine a t shirt that is completely environmentally friendly, super rip resistant, bullet proof, and insect repellent.
And sticky
@@SuperCarneBoy *Yes!*
"And sticky"
Ummm... on second thought... 🤣
And affordable
One size fits all too!
You know dang well we’d make the farming process bad for the environment even if the silk is perfectly safe
Spider webs on their own are actually the best at picking up audio. A spider sitting in the middle of their web is actually listening to their environment with their body hairs, and the shape of the web is actually 100% loss free when it comes to audio and can detect it from incredably long distances.
As if spiders needed more super powers involving their web.
Edit: Its Kyle Hill, ”spidey sense is real” I believe.
ruclips.net/video/pfeCp7p1uBc/видео.html
source: just trust me bro
@@mastershooter64 I do know that Kyle Hill made a deep dive and explained it in a live stream. I might still be able to find the vod, it wasn’t too long ago.
I know this is an old comment, but just wanted to mention that it is impossible for it to be 100% loss free. Some energy will always be lost.
Yoooo headphones with spider silk-like technology
Have we considered the possibility spiders might be too small? If we geneticly engineer some of the more social spiders to be the size of sheep we should be able to produce massive quantities of large high quality silk... What? Why are you looking at me like that?
I fully endorse this plan, sounds good. But, then again a spider's size is not limited by their genetics but rather the amount of oxygen present in the atmosphere and the amount of times they're able to successfully molt.
imagine the flies though!
@@kylekaut7404 Well, the biggest modern arthropod on land is the Coconut Crab.
I'm looking at you that way because *large herds of giant spiders* makes part of me think "What an awesome sight that would be!" While the other part shakes in uncontrollable terror.
Imagine a whole artificial environment where we could grow generations of spiders in high-oxygen environments, making them bigger and produce more silk!! Would actually be a great workaround to get the amount of silk we need for anything truly practical
When I was at the university I had to do a presentation about spider silk, and I have to say I missed some information in this video. Like how spider silk is already used to make sport shoes because it's antibacterial and won't start to stink. Also how it has already been used in history on wounds or how it could change future medicine in terms of prevention for example breastinplants from inflammation or to use spider silk in compressed form as surgical screws, so that they don't have to open the person again to get the screws back out. Well my presentation took like 40 minutes. 😅 I am so interested in these topic.
hey man i am currently researching things in spider silk. can we talk some more ?
@@stonedcat1562 hi, well I got all my knowledge from studies and articles that I found on google scholar. I would recommend searching there. I don't know if I would get all the facts right, because it's been a while since researching for it myself. I can only get some bullet points together. 😅
I suspect my room-mate also has hygroscopic properties - he effortlessly absorbs every liquid in my liquor cabinet...
Hot Take: Sicence-Fans have Tunnel-Vision, kinda. What about you? Do you watch Channel that can be summarized as 'Problem-Tacklers'? Illumiinaughtii,
Some More News and... well... the entire Concept of Atheist-Channel? I mean, even if the recent Abortion-Thing had never ever happened, they would stil be the main-source of valid Criticism and problem-identifiers on YT, wouldn they? So it worries me that Sci-Fans only wanna be updated on Fun Science Stuff but not this.
I hope biotech and genetic editing are fully embraced by everyone so that we can all benefit from this and other possible advancements sooner rather than later
read hellper bro
Don't hold your breath. People are naturally hesitant about everything, even if it's going to improve their lives.
@@johnbauer8564 unfortunately :(
We just need to stop greedy corporations from ruining its public image even more.
what about spiders rights?
This kinda reminds me of an old fable from my tribe, about an 8 armed woman who spun webs for her family and her warrior tribe. Arrows bounced from from the armor she made, it's crazy to see that now becoming a thing
I've often wondered why Spider-Man never makes his costumes out of spider silk.
It's actually too stretchy! If the enemy grabbed the mask by the nose and pulled it back, they could see Peter's face through the stretched mask like a panty hose.
Idk really. Then again, if the collector of all knowledge doesn't know it, how are we supposed to?
@@deldarel actually that would be beneficial, just like how wolves or wild mammals have loose skin around their neck so that when they get bitten by a prey, it's likely that the skin glides across the meat underneath and avoid actually getting bitten
supercontraction. imagine wearing your spidersilk underwear and pants and it rains. The fibers shrinks as they absorb water.
ah yes, spider silk: the future of engineering! and has been for the past several decades, along with programmable metals, and carbon nano tubes (which tbf are finally starting to see actual real use in the construction and even defense industries).
Don't forget fusion reactors!
There was quite a big time gap between plastic being invented and it being used commercially. Now plastic is so common that its a problem. Any new invention no matter how great takes decades to commercialise.
Came here to say basically the same thing. I've been hearing about the "wonderful uses of artificial spider silk" for 50 years. Like batteries that can be recharged an infinite number of times, and charge from zero to full in 5 minutes, it's always "just a few years away".
There's also graphene.
Programmable metals? Never heard of them but they intrigue me.
I always cherish my childhood as we used to catch and pet orb weaver spider, there is a dedicated months/season in our town where a tournament sort of is being held. As a child I always wonder how each spider differs and the way they produce silk. Good to see that they are now getting more recognition of how awesome these species truly are.
There's actually a company that is very close to commercializing spider silk from genetically modified silk worms, utilizing spider DNA to create incredibly strong silk that can be produced and harvested using typical silk production processes. Kraig Biocraft Laboratories started at the University of Notre Dame, now has offices in Michigan, and has a production facility in Vietnam that is ramping up to full production.
id be curious to learn more about the "spider goats" how they produce the protein for spider silk in their milk. is that a viable way to mass produce the silk or are the spider goats, just a neat example of dna manipulation.
The buddy group was joking about the spider goats in the early 2000s. It's the earliest test concept that I know of.
bacteria production can be scaled sooooo much higher and so much faster. the goats would take gestation cycles to try new runs, doing bacteria is hella fast
Spider goat, spider goat…
The spider goat project is canceled.
So glad you covered Nano Cellulose!!
I remember when a lab genetically engineered goats to produce milk that included spider silk proteins.
They were producing a lot of the protein but the strength of spider silk comes from both its protein structure and the physical structure (the way that spiders physically weave it.). It's the same way hair and nails are mostly made of the same stuff but have different physical properties because they are physically structured differently.
Getting the precise mechanical weaving is probably going to be the tighter bottleneck than creating the protein strands.
"The ultimate tiny lab assistants" Anyone else get the image of a spider in a lab coat?
Aside from the amazing, and downright inspiring uses of spidersilk, PizzaJohn on your abdomen makes me smile.
Thank you Hank, see you on Friday.
Sticking a label on a, wet surface at -196°C is a, lifelong dream of mine 😁
Just another reason to love our spider bros.
Cool show!! If cellar spider silk becomes a thing...I could retire from a drag line harvest in my storage unit!!😁
Does this SCIENCE-Channel not have the Guts to tackle Hot-Topics?
Others stand-up against Trans-Hate and LGBT-Hate flaming-up right-now,
but no, not this channel.
@@loturzelrestaurant why would they science is supposed to be this way, it's not a political channel.
Wouldnt using moisture-level to control spider silk robot muscles result in slow and imprecise movement? And having to control the moisture level precisely seems impractical to me.
I think it's less "change humidity to affect movement" and more "maintain humidity to guarantee exact distance during a movement." I don't know if it's related at all, but I could also see the stretchy characteristics being useful in "soft" robotics where automated robot need to work around humans and a collision could be very dangerous or fatal.
To me it sounds more useful for mechanical tools that need to stay the exact same distances across various temperatures and humidities.
Hmm.... I'm having pest issues in my garden, both with my beans and squash. Squash bugs are a bit of a scourge around here. I wonder if there's some kind of gauze mesh I could get and draw over my plants...
Thank you for making this video
The microscope shown at 8:03 does not work by focusing light at all! This is an atomic force microscope and works by scanning a tiny needle across a surface and measuring the topography at a nano scale. This type of microscope, used by the authors credited on screen, does indeed achieve a much higher resolution than optical microscopes, and is used by microbial biologists (and many other fields), however it would NOT benefit from better lenses, because it does not use lenses or light to image.
(Yes, there are a few lenses in this machine too, but they are used to guide the laser to measure the deflection, but a higher resolution or quality in these lenses would not affect the resolution of the microscope.)
The picture was probably just meant as a generic picture of A microscope that can see the smallest of objects. Not specifically one based on light.
I would be proud to own 'spider made' glasses. Both the 'plastic' frames, and inspired lenses! (◍•ᴗ•◍)❤
I always wondered if social spider species may be a better candidate for harvesting silk. Short strands can still be spun together, they just won't be as sheer or useful for embroidery as silkworm silk. Then again, I'm also trying to get eri silkworms to help with eradicating invasive castor but I'm having no luck
My dream of becoming a spider rancher may finally come true.
This is so cool! I love every part of this!
10:45 The arrow-shaped micrathena! I found they can be aggressive when agitated. I only did it once.
Remember reading this "how spider silk will revolutionize manufacturing" since last 30 years.
Love this, frack I love this channel.
I keep ladybugs and spiders all over my garden like I will bring spider to it to help out they love it my crops don’t get touched no pesticides everyone is happy
Indeed! Why hang individual strands if you can place a box of spiders near your crops and let them sort it out?
I thought it was odd you didn’t mention Kraig Biocraft. They are already producing spider silk from genetically modified silk worms. They have Contracted with a mill currently producing mundane silk in Vietnam. They are on track to produce metric tons of spider silk by the end of next year. You can find them on RUclips.
Always interesting, thank you.
i love this channel it's got me interested in science again and i'm an r&d scientist haha 😂
I've tried to explain the same concept to my boss, but he doesn't see that watching TV re-invigorates my interest in my job.
Did you see the suspension bridge? That's in Cincinnati! Yay Cincinnati! I'm from Cincinnati btw.
I heard that George Clooney if pushing for production of the sequel, 'The men who stared at spider-goats'.
Spider silk has been the future for at least 40 years.
Fantastic video, as always! I just wanted to point out that for the use of spider silk in engineering more sustainable plastic alternatives, the fact that it biodegrades is probably not the reason it is advantageous. Some plastics are advertised as being biodegradable, when in actual fact they break down into microplastics which pose their own threats to ecosystems. Ideally, the materials we use should be compostable, because then they can truly be broken down in a non-toxic way.
scientists made a large cloth made of golden spider silk that is on display in the smithsonian museum of natural history. It's a priceless piece that used over a million spiders to make.
Thanks sci show, great report. I care and I like it
Cool thanks
im so glad for the spider silk microscope
i hope we have spider habitats in the future
Thanks!
@4:50 Should I ever find a wet surface at -100°C, you bet I'd put a sticker on it :D
Spiders, one of my heroes of the critters world! And to think they can help us make a better and _safer_ pesticide? Woo hoo, hell yes! I LOVE that!
Thanks, SciShow and Hank, for all you do!
1:59 Yeah. Good idea. What could *possibly* go wrong?
You should take a look at Thought Emporium's video on spider silk.
Spider silk space elevator? Or perhaps that tension strength could be used for the arm of an orbital accelerator?
Its impressive how one of the best materials to exist is made by a small insect.
Anyone catch Sam Schultz taking a nap in the ad at the end? Made me
laugh out loud!
I love seeing John's face on Hank's chest.
I was looking for a comment about who that is, so it's really Johnny Depp?
@@dariushmalek6325 John Green...
@@Em4gdn1m Thanks man, I didn't know who that is!
@@dariushmalek6325 ah. Yeah his older brother, he's awesome. I love him just as much as Hank!
I'm just waiting for the day when silk in clothes can be produced cheaper than polyester or cotton. Silk worm production isn't great a they have to keep massive warehouses temperature and light controlled to keep the worms and trees they like happy. I buy used silk, but it'd be awesome for the luxurious material available without such a carbon footprint and considerably cheaper!
If we want to try making the space elevator, spider silk will be something we will probably need to learn from.
I just want me some Spider Silk PJ's. They'd be so comfy
Freaking love spiders.
What is the practicality of potentially breeding or otherwise creating greatly bigger spiders, capable of producing more silk at a time?
Spider silk garden fence... Hmm
Most spiders are completely harmless, yet a lot of us are completely, constitutionally creeped out by them. Perhaps there was a time in our species where we were constantly getting bodied by spiders? Maybe one of the ancestors of the Australian spiders?
Imagine instead of tiny spiders biting you, it was giant spiders boxing you.
Eight legs of fury! KNOCKOUT
I hear that when we were nomads, we would come across spiders much more frequently in the wild while walking through fields, and of course they bite out of fear of being crushed
my favorite animal, so adorable
@@joseabarzua8831 Dangerous spiders are also much more common and widespread outside of Europe and North America.
9:50 the strands contract and twist. Is the web ringing itself out?!
Any SciShow Halloween Shirts with Spiders? 👀
the wierd thing is if you made a spider about as big as a small dog like a Chihuahua the silk it produces would be about 1/2" to 1" thick and that would make it easy to harness the silk and all you have to do is change the genes of the spides growth alittle
Chihuahua spiders sounds perfect for the time of armagedon
@@samuela-aegisdottir *srug* I know I'd love one that big hehe would have you probably make bugs bigger or I may start feeding on neighbors pets and small children
You joke, but keeping labels on frozen samples that go in and out of -80C freezers would be amazing!
We are getting closer to being spiderman
I couldn't concentrate and listen John staring at me.
Nice video!
the other day i road my motorbike to the village, then noticed a spider web was still there stuck between the tread on the tire. i was amazed.
Number 7: Become Spider-Man
Can't we just engineer giant spiders? that could be very cool :D
They answered this a couple months ago. I posted the link but idk if youtube will delete it or not.
ruclips.net/video/O7aTfDVP1LU/видео.html
Without lungs they have a size limit. If a spider got too big it would suffocate, since the current concentration of atmospheric O2 would be insufficient to diffuse through their microscopic breathing holes.
And giant spiders might have a few... less than desirable side effects. See: horror movies.
So amazing!
I want organic spider silk only. Build spider milking machines!
Buen video, no me extrañaría que estén viendo la telaraña a diferentes atmósferas, resiones, gases y temperaturas para sacar todos los secretos, sería interesante ver si en la luna titan sirven los Bio químicos como este, sugerencia.

Spider silk... New Breakthrough... Any day now...
Same thing I've been hearing for 60 years.
Nylon is made in a similar way to silk. I.E. it's pulled from a liquid & forms the strand as it's drawn out.
Very cool
I feel like they've been talking about this for the last 20 years
All we need is...
Spiderman!!
TheThoughtEmporium has already been able to produce spider silk from yeast. This will be available relatively soon assuming my understanding is correct of his intentions.
Spiderman knew this forever ago.
Stark did it.
I hate spiders but am genuinely interested in this video. I looked away every time a spider came onto the screen. 😂😂😂😂
Can you imagine going to your first day at a research lab, and open the PPA closet to find it full of webs and a over-fed spider. "Oh, that's Chel. Don't mind her. She makes all our lenses."
I'd make "friends" with Chel so fast....
It can also let you swing through the skyline of manhattan, quipping at old men dressed like vultures and octopi
Just reading the headline here makes me curious if this is a repeat of something that I saw about 30 years ago.
Kraig Biocraft Lab is mass producing spider silk now.
would almost say, finding a wet surface at -196c is the real feat.
dude i have like 15 to 39 long/bodied cellar spiders just living in various corners of my bedroom... i never knew i could put their silk on my microscope lenses! /j
Yes! lets make spiders a regular part of laboratories, there's no way that could go wrong! oh no are those giant maneating spiders?!
All jokes aside I didn't know spider silk was this useful, I "only" knew about the potential for it to replace stuff like kevlar.
Im surprised you didn't mention spider goats
Wasn't there research or something going on with goats and silk? Straining out the silk from milk?
What's damp at -196 Celsius that you need a label on?
I would love to have labels that would actually stick to stuff I store in the -80C freezer in my lab. I have to put sticky notes with labels inside the boxes, which isn't the best labeling scheme
@@Megan-nt7dm thank you for the genuine answer; I was hoping there were real applications
@@charleshammel8541 I also completely forgot about our liquid nitrogen tank, which we keep vertical racks with boxes in. That is at -196C, and if I want to label something, it has to be in sharpie. I'm not sure liquid nitrogen is considered damp though. Like it's "wet" but it becomes gas at room temp? Idk cryo liquids are weird
Edit: we use this for long term storage of cells. For my lab at least, it's mostly human induced pluripotent stem cells. We get them from patient blood, then reprogram them into stem cells, then make them into neural progenitor cells
@@Megan-nt7dm our lab has special labels for frozen specimens that stay on the tubes at -80°C and in liquid nitrogen. It took them years of trying out different label types to find ones that work and they're very expensive.
@@Megan-nt7dm this is the coolest thing I've heard in a youtube comment in a long while
Spiders make me feel scared but I don't kill them
Is that John’s face in Hank’s shirt? What does it say beneath it?
Maybe we could genetically engineer Cambrian spiders the size of large dogs, and raise them in an oxygen rich habitat. During the Cambrian period, they had 19" spiders, that's not too bad. :)
Spiders started in the late Devonian and the largest spider species to ever roam the earth do so right now.
I think you're thinking of the sea scorpions, which weren't arachnids but closely related.
@@deldarel talk to Google then
I've been hearing this for literally 30+ years. But I'm sure this time is different. /s
Time to open a spider farm with spider herd and spider shepherd and call him spiderman
I wouldn't advise investing your lifesavings in projects seeking to utilize spidersilk. It won't be too long before some major breakthrough in quantum computing opens up that field for the industry to use and then stuff like nano assembly is going to follow is short order. *Then* spiders will study us to figure how to make better silk.
Hi John! I see you peeking out there.
