A glass that builds and heals itself 

A vegan sausage is still a sausage.

Technically, any amorphous solid is a glass

Nature is using clickbaits now. LOL To be honest, publishing some research, even in a journal, has an element of clickbait to it. Material scientists are notorious for 2 things, a) Accidental discoveries 2) Clickbaiting their discoveries

I guess the question is; can it perform the same functions as regular glass, and the answer seem to be yes, but that's just my impression.

@@nerdpower-2288 regular function of glass? Like, being hard and chemically resistant? Doubt it.

Clickbait.

if anything transparent is glass, then we breathe glass

​@@JNJNRobin1337hence never sees video as the real information , just like you can't understand literature like lord of the rings by just watching the movie. Read the book or research... Nice video nevertheless

Probably yes, I would say. In the video it says that the structure is stabilized by water bridges, that cracks form if the glass is “dehydrated enough”, and then heal in a moist environment (so the water bridges that were lost and so crack were created are replaced, I understand). So I would guess that the curvature is determined at the moment of drying-assembling by the conditions/concentration at that moment, and that as long as not too many water bridges were undone by drying and the general structure/shape remains stable, the bridges will be replaced but nothing else will change. Like if you build a dome out of (a LOT of) balls and rods, and afterwards take out a few rods, the dome shape is the same, it’s stabilized by the remaining balls and rods. Then the only places where the rods can be placed back is in the original positions. My educated guess, but I could be wrong

There's a chance that after enough usage, the lens could change its diopter, still, it is way more reliable and could be corrected too without getting a new one

Given the amount of maintenance required for certain lens applications, this looks attractive. Certainly this is the start of a new branch of materials research. Also, there's been a related lens discovery, high refractive index allowing to compact telephoto performance into a tiny area

Put a damp towel on my cracked phone screen for a day and it's as good as new, I'd be down for that.

​@@The-KPcurious about what you mean by high refractive index lenses? Any link to a paper?

Maybe they can coat it in something that can trap the water in?

You could possibly coat it with silicone and it won't lose moisture.

I’m sure it’s meant to click bait, but it’s clear like glass, like crystal so essentially I suppose “glass” is meant as “clear.” It sure doesn’t “break,” so not glass at all but polymer gel…. 😊

O ay small world, yeah they're rather stretching the definition with this one to something merely brittle and transparent. Glass resembling. Otherwise an interesting matter though.

I think that's how they use the word "glass" in material science.

​@@aron8999 Yep, the opposite of glass is crystalline. It's ordered (crystalline) vs unordered (glassy). Metals can take on a glass state too. It's got nothing to do with being clear and being able to shatter, although admittedly things that shatter are often glassy, but not always as obviously crystals can shatter too, but the way it happens is much more predictable due to its ordered molecular structure.

@@Zeero3846 Yes, I didn’t bring up clearness because obsidian (an opaque silicate glass) exists.

Thousands of new attempts to patent "thermally refreshed bread" (toast) every year. Thats how you grab invention ,put a new name on it

glasstic? peptitoglass? optical peptidopolymers?

@@iamdmc Aminoglassids!

Maybe usefull in odontology

I mean... pure soda glass is also water soluble. But I agree, the term "glass" refers to a lot of wildly different things.

Changing the scientific meaning of something because people aren't educated is about as stupid as the uneducated people

Yup, almost the same.

😂

it dissolves in water

There was the 'looking glass' in the 2017 video game Prey.

But it has to stay moist all the time.

in warmer and humid climates only?

@@SonnyDarvishzadeh That's just where they'd work "best".

If you can't be bothered to do a simple google search with keywords like, "self healing glass/polymer, nature magazine", can you really be considered a researcher? Do you really need information spoonfed to you?

yes, I pointed out that error first. Somehow I hate it even more now that they decided to do a full reupload instead of staying true to their mistake and leaving a note. On the hand, this is educational and therefore better to have it fixed. Still weird though, that a journal with such a huge amount of money (due to high journal and especially submission prices) has no sufficient quality control for < 4 min videos.

What's the difference between a peptide bond and a nucleotide bond in the grand scheme of things. Energy is added and water is extracted.

@@kentowe2080 there isn't. But the original video claimed that DNA and hair are made from the same building blocks.

@@TMtheScratcher Well of course hair is made of the protein keratin. DNA specifies the amino acids it contains.

@@kentowe2080 yes but the way they formulated it, it was just factually wrong. That's why they reuploaded or least changed it in the reupload

Eh, I wouldn't exactly call some amino acids dissolved in water "technology"

@@dahlia8027 I would also say it's more like an observation. In any case, I think it is unnecessary to create a connection between scientific discoveries/inventions and a nation, as science is in any field a long term collaboration of humanity. While these scientist may be from Israel (or their lab, the people might be from any country, I did not check), all the tools they used which led them til here are from across the world.

It's not just unnecessary; it's sad.

What is this glass called “genocide”

Nationalism is a foolish thing to proud of, get over yourself. It doesnt take effort to be born somewhere. It was a lab not a nationality. What a weird way of thinking
