I don't think people realize yet how we are in the very very very early ages of material science. This breakthrough is one of the first in ushering us into the Super Materials Age. We really don't have long fibers yet. If we can keep tweaking this until we can make extremely long single-strand fibers. That will enable new kinds of technology and infrastructure we can hardly imagine right now, including space tethers.

As a materials scientist, I whole-heartedly agree with this statement. I remember talking to one of my professors in the 90's about his breakthrough accomplishment in the 1960's, which was a new way to process aluminum. He likened his innovation to "churning it like ice cream." In the early 2000s, 40 years later after his innovation, I was working on nanolayer technology - bioactive layers that were only a few molecules thick (ideally only one). I can't imagine what we'll have in another 40 years.

Yield strength is the measure of how much potential force it can take without yielding (like a spring). Ultimate tensile strength is the measure of how much force it can take before it fails.

Really interesting video and overview of the unique attributes of spider silk. Most people don't understand the difference between tough and strong. That said, this isn't the first time recombinant spider silk was created, and certainly not the first time it's been done using nature's best protein factory, the silkworm. In 2012, twelve years before this video, the PNAS published a paper titled "Silkworms transformed with chimeric silkworm / spider silk genes spin composite silk fibers with improved mechanical properties". Here at Kraig Labs, we've been producing spider silk using silkworms for years. We're taking the excitement and potential of spider silk and leveraging our silkworm-based production system to turn that into a reality today.

[@OneBigBug]

The definitions given here for "strength" is either very misleading, or (I would argue) downright wrong taken in context, which becomes kinda grating as it's used throughout the entire video. In the video, strength is defined as "being difficult to change shape", and then examples are given (pencil vs rubber band) as though that definition is true. But strength (or at least "yield strength" which is generally the default implication of "strength") is about being difficult to change shape *permanently*--the amount of stress that can be applied before reaching plastic deformation. Plastic deformation is the deformation that occurs after elastic deformation. A rubber band is very elastic (hence "elastic bands") so it's a very confusing example for highlighting that difference in this way. A rubber band may be very strong, perhaps sometimes stronger than a pencil. It will droop when the weight is applied, but as long it snaps back into shape when a weight is applied that would snap the pencil, it'll still be 'stronger'. What a rubber band is not is "stiff". Stiffness is the property of a material that resists deformation of any type, elastic or plastic. A pencil is much stiffer than a rubber band.

[@iwanttwoscoops]

the applied voltage is an action potential- a neuron firing. It induces a protein signaling cascade removes inhibitory (tropomysin/tropomodulin) proteins from molecular motor proteins which pull on those “hairs.” It has nothing at all to do with the voltage itself; it’s just how neurons communicate, and wouldn’t do anything to spider silk man

[@juschu85]

You have to admit that the title "We Finally Made Synthetic Spider Silk" is a little bit clickbait. Let's ignore that it's "just" worm silk with the properties of spider silk. But even though the worms are genetically modified, they are still the ones who are creating the silk. The silk is still produced by living beings, so it's still no synthetic silk. If we actually had a sythetic way of producing it, it wouldn't just be vegan, which arguably doesn't matter to most people, it also would be much easier to scale the production, wich does matter to most people.

[@renchesandsords]

I have gripes to pick with the definition of strength and toughness provided. I've always learned that strength (UTS) is the amount of constant force required break a material (pulling a test sample apart slowly), whereas toughness is a function of how much energy a material can absorb before breaking (dropping a swinging hammer and seeing how much lower it swings up after breaking the material)

This is a pretty cool discovery. I remember seeing an article a couple years ago where scientists also genetically modified goats to produce the same proteins in their milk that spider silk is made from in a similar attempt to mass produce it. If I remember correctly, their approach while capable of producing large quantities of the spider silk proteins had trouble turning those loose proteins that were dispersed through the goat's milk into actual threads with the same kind of properties as actual spider silk. One bit of feedback I would like to offer on this story is that you seem to conflate toughness with ductility quite often. Typically when a material has higher tensile strength, it is also harder and more brittle. Similarly, something that is very ductile usually doesn't have much tensile strength. Toughness is a measure of both a material's tensile strength and ductility, and is usually plotted on a graph of tensile strength versus ductility as a series of points. The further up you move on the strength axis, the further down the ductility axis you will typically find a material. Materials that are strong, but not ductile, tend to be prone to fracturing and cracking when stressed, resulting in what is called brittle failure, which is often sudden and happens without warning. Picture trying to bend a piece of chalk in your hands. It will typically handle a fair bit of force until you reach its yield strength and it suddenly snaps. This kind of failure is very bad in things like buildings and bridges as there is no warning before sudden catastrophic failure. Materials that are more ductile tend to undergo what is called plastic deformation when they are stressed beyond their yield strength, which is where the material permanently stretches under load, but will continue to stretch gradually before eventually breaking rather than suddenly snapping. For this, picture pulling down on a piece of taffy. If you pull with only a small force the taffy won't move, but once you reach its yield strength it will start to stretch and deform plasticly until it finally breaks. A tough material is one that will support a lot of force before yielding, but still has high enough ductility to undergo plastic failure rather than brittle failure. There are very few truly tough materials, and spider silk is one of the toughest we know of, which is why finding a way to mass produce it is kind of an engineering holy grail.

if we can get space elevators rolling we can start seting up solar pannel bands around the earth dealing with energy issues, then we can get onto setting up bases on the moon and move into hearding asteroids and eliminateing resorce issues for rare earth metals, we would be creating multiple big aeras for emplyment and many other issues like evnergy would more or less auto solve as those are held back by resorce issues

[@omnitoad2187]

Though, we gotta call it something other than "Spider Silk" since spiders aren't even part of the process. I suggest "Sylk" for the cool sci-fi synthetic silk branding. But it's a good opportunity for all kinds of stupid names, "Super Silk," "Worm Fiber," "Butt Thread." The possibilities are endless.

[@sandwichqueen]

Honestly, super silk would probably be the name of it. It's simple, while also describing the big deal of it.

[@lindaward3156]

I never understood fear of spiders. Sure, they can temporarily startle a person when they scurry out from an unexpected place but dang, a person is so very much larger than them, easily dispatched if needed. I think they're kinda cool with what they can do, like in this recording. But again, w/o their own PR, they have a majority of people scared of them, even tho most aren't at all dangerous!

[@GabrielPettier]

Microbes are so small to be kind of invisible, but can still kill you, some spiders can kill you, too, and at least they are visible, so i'm not surprised we have some innate fear of them, and it's a lot stronger in some people than in others, it must certainly have been useful at some point, i'm not particularly afraid of them, but some level of caution is not a bad idea. I like the small jumpy ones though, very cute.

That's why it's called a phobia, or an irrational fear. (signed, an arachnophobe who also thinks spiders are pretty neat... at a distance.)

Something being called a fobia does not mean it is not dangerous.

[@FiddleSticks800]

Most of our synthetics are stronger than steel by weight. And spider silk is just slightly tougher than Kevlar but distends much more. In other words, it may stop the bullet, but it will be half way through you by the time it does. And water plasticizes spider silk such that it looses its yield point and most of its toughness. Synthetic spider silk will only ever be a novelty.

I know it's a bit late, but when I'm discussing the difference of material deflection properties to people who haven't taken a class, I prefer to use the term 'stiff' where you used 'strong'. Strong is the amount of pressure needed to achieve *permanent* deflection. It's a bit more complex, (assuming things haven't changed since my classes earlier this millennium) but close enough and helps to picture them to different properties that are related.

[@tadhgbarker4050]

I'm working on worldbuilding for a book I want to write, and I actually have a civilization that farms specially bred spiders, giving them relatively large prey so that the spiders wrap them in their silk. The farmers leave some prey for the spiders to eat, and take others, essentially treating the collected bundles the same way we actually treat silk worm cocoons. They use the fibres for durable yet fine clothing, strong ropes, medical practices (primarily sutures, but also as, say, packing material to stop deeper wounds from bleeding as much), and those sorts of things. The selective breeding over time turned out spiders that were less aggressive to each other and the farmers, with large abdomens and spinnerets to produce more silk faster. Over time, the farmers also bred larger prey so that the spiders could sustain a larger size, as well as produce more silk per bundle. Obviously all in my head, and I'm not sure if that kind of thing is even remotely possible in real life, given enough time and patience, but hey, we still want to use spider silk, so I'm happy with my description.

[@Termini_Man]

Oh god, I hope this allows us to make space elevators. Space elevators are awesome. by steeling a small bit of energy from the earth's spin, we can put things into orbit without an ascent stage, which is by incredibly far the part that uses the most fuel. So it could be incredibly practical to put things into orbit. I hope i get to see one in my life time.
