Fascinating! Many years ago I gave a report on how the color change happened, and it was via chromatophores - tree-like cells that shifted their "branches" causing the color change. I can see how that was refined into this, since the shifting part of the cells is obviously the important part. What was missing was the nano-crystals, which makes it much more logical and much cooler. Thanks for the video!

Hi. First time I comment on your videos, so let me say I really like your channel. As a scientist, I find that a lot of youtube content falls way too short on communicating science in an accurate and accessible way, but your videos really accomplish that. Everytime I watch one, I learn something new. I am a photophysicist and I deal with colors all the time, so I really enjoyed this clip. I just want to leave a small correction. The green color cannot be created by the combination of yellow pigment and reflected blue light. This is something that I find hard to explain to colleagues and friends that do not usually work with optical materials, but pigment color and light color are not the same, and actually, they are complementary (opposite). Light has 3 primary colors, Red/Green/Blue (RGB), and pigments have Cyan/Magenta/Yellow. For a pigment to be yellow, it will have to absorb blue light, and reflect Red+Green. Thus, the Yellow pigment would absorb the blue light reflected by the nanocrystal layer, or, otherwise, the color would be white. To yield green, the nanocrystals should reflect green, and the pigment contribution should be minimal. If the information on that study is written as you explained here, it should not be correct. Keep up the good work Cheers

Am I the only one who noticed that the KZfaq like button is now measured in K ? K comes form the Greek kilo which means a thousand. In the metric system lower case k designates kilo as in kg for kilogram, a thousand grams. Even here there is some ambiguity. In the language of computer science K is 210 = 1024.

I'm upset that people refuse to adopt KiB, MiB, GiB, TiB though. Creating confusion with SI units is a bad idea. Also, no, kB and KB aren't different. kB is just a misspelling of KB.

Do we know if it's a conscious choice to change color or if it just happens? Is that even philosophically solvable? What I mean is, is it like us getting goose bumps in cold weather or is it more like us shaking our fists at people we're angry at? Does the chameleon think "Oh damn, a rival, better move around those crystals!" or is it an automatic thing that goes hand in hand with an accelerated heart rate or whatever happens in the animal's body during a rival encounter?

The Real Flenuan I'd say a significant extent. Small sounds... too small. Some emotions are deeper than others and are virtually impossible to tackle except by long time and effort, others, like fear, anger, anxiety... we can often reason ourselves out of them relatively easy. Ruining our own happiness is also ridiculously easy, but nobody really tries to make an art of that for obvious reasons. Our emotions can be powerful, but I really think that depending on the person, more often than not, we do have the power to make a difference on our emotions. We can also of course consider the fact that we sometimes make the wrong choices and suffer the emotional consequences of them, and while we may not be able to deal with the consequences, we did after all make the consequences so we kind-of did exert power over them.

This is definitely interesting because it's different than how octopi change colors but with octopi and certain species of chameleon the skin color can be changed to match its surroundings.

The easiest way to answer your question in a less scientific approach, studying a chameleon won't harm him. Cells could be studied by simple getting a fragment of their skin, saliva, or anything an animal produce. However, studying an animals biology and systems specifically leads to what students call "Disection" which literally leads to inevitable death. However, those act only happens to few animals who passed consideration. Meaning they don't just kill animals to study at will.

the extent and 'severity' of animal testing has to pass an ethics panel and justify any harm caused as worth it in terms of impact of the research being done. since this isn't exactly 'high impact' science, I doubt they would have gotten approval to sacrifice them. but i imagine getting ahold of an already expired chameleon corpse isn't exactly hard to do either

Yes, kinda. It's called an optical interference display. You basically take two plates and change the space between them to change the wavelengths that constructively interfere. There might be a way to make colored e-paper this way. Aside from plain issues of manufacturing these things cheaply enough, there are two issues that I imagine: one is that you can not mix colors freely this way, so magenta is out of the picture (no pun intended) and the second is that you can't up- or downregulate the amount of light you reflect so producing desaturated colors and colors with less lightness is a problem (especially, say, black). White is probably not as much of a problem as one might think because plates that are far enough apart won't cause any interference in the visible spectrum at all and therefore the white or backlit background shines through. One would probably solve the saturation problem with an LCD layer between the white background and the color-producing layer but how one could change value/lightness and saturation independently from each other is not clear to me. Maybe a backlight that can be regulated on a pixel-level solves this problem ... or you'd need cells that can be reconfigured so quickly that they can switch between white and color quickly enough to use the same PWM trick DLP projectors use to change brightness ... I'd have to think about this. How many stacked layers of color-producing cells you'd need to get at least the RGB color space is also not clear to me.

I dont get it .. he said "They actively tune the spacing between the nano scale crystals " ... So how does a chameleon do it ... I mean does it consciously stretch ? OR generate heat which results in stretching? Is it a physical process or a chemical process. What exactly is the mechanism? This is like saying "Giraffes stretched their neck during evolution, this makes us think that Evolution is like a conscious process in the grander scheme of things and its manipulating the course of things, which it is not. Giraffes stretching their necks is false, cause its just that the ones with shorter neck starved out and this genetic advantage of longer neck was passed on to the offsprings. Just survival of the fittest; plain and simple." Now I would definitely see replies asking me to refer some scientific journal for the details. But I am just saying the language used needs to be refined and scientifically accurate .. thats all :0)
