Finding natural blue in nature is actually pretty uncommon, as it's really difficult for life to create blue pigments-but the color can appear in a handful of compounds that create just the right conditions to reflect blue photons! Learn about the blue phenomenon in this fun episode of SciShow!

6:30 I love the Idea of nature being like "alright guys we managed to barely make this work, NO ONE TOUCH ANYTHING"

@glenngriffon8032 3 года назад

Well that's what I love about evolution, it really does work on the cheapest budget. The principal of "good enough" or "forget it, that'll do". Evolution only cares about one thing: You live long enough to reproduce. Did you make a child that has birth defects? Doesn't matter to evolution. If that child passes on it's genes then it's a success. That's why i have vowed that I will never have kids. I know full well that my genes are bad and my parents really shouldn't have had me in the first place but they did. And my birth defects kept me in hospital for much of my childhood. So I'm not going to repeat my parents mistake of playing genetic russian roulette and just hoping my child gets lucky to not inherit all of my bad genes.

@TheBanjoShowOfficial 3 года назад

@@glenngriffon8032 personifying evolution is already a cardinal sin of its own. It isn’t a person residing over a computer, it is merely an algorithm that functions based off natural feedback and beyond excessively redundant iterations. It does this over and over again until something seems to continue to exist, then that creature ceases to change what behavior already works. Trial and error, trial and error, millions of years.

@@TheBanjoShowOfficial Dude, other than you being a pedantic ass over space-saving metaphorical shorthand, there really is no difference between what you just said and the person you're correcting except your metaphor is even worse because it implies not only an end-state but that there's a planned sensibility to the whole mess.

@TheBanjoShowOfficial 3 года назад

@@Just_A_Dude No, there is definitely a difference. The metaphor works only in part. By using it, you'd be assuming the fallacy that evolution has desired outcomes, of which is most certainly does not.

@masterimbecile 3 года назад

Bilirubin and biliverdin is also why your bruises change color! A hematoma (bleeding into tissues, i.e. a bruise) is cleaned up by white blood cells as they eat up the red blood cells. The heme molecules in RBCs are broken down first to biliverdin, and then to bilirubin within the WBCs. This is why your bruise starts from red, and then changes to purple, blue, green, and finally yellow before disappearing. The bilirubin is finally peed out in the form of urobilin, which is why your pee is yellow!

@@darrenswails We aren't completely sure about all the mechanisms, but bilirubin in high levels seems to interfer with the actions of some enzymes and otherwise interfer with normal cell function. Very high levels (beyond the solubility limit in water) will also cause the precipitated bilirubin to start accumulating in the gray matter of the brain where it acts as a toxin, destroying neurons and leading to permanent brain damage.

@strangebird5974 3 года назад

This was really interesting. It was a nice example of how a seemingly simple question can lead down a path where surprisingly complex knowledge is required to answer it. Also, the thing about many chemical blues being toxic is probably a clue to why animals and plants might use that color to signal that they are poisonous and not good to eat. I'm thinking of the blepping blue tongued skink that animalogic had a video about the other day. Anyway, it's a working hypothesis. And also, I feel this video is for me, because I remember leaving a salty comment on an earlier scishow video about the same subject that didn't really touch upon the answer. So thank you, scishow!

Close. The purple was from bacteria rather than plants.

When you stop to realize that blue and purple light is more energetic than the other colors, it makes sense that these colors would be "missing", since they'd be absorbed (rather than reflected) to provide more energy for photosynthesis.

3:08 the company I work for makes metal orthopedic implants, they are almost all cobalt and titanium. One of the interesting things with these metals, they have to be encased in something before they can be put into a person, usually a type of cement or porous coating, which also assists in the bone adhering to the implant. I've never heard of anyone getting cobalt poisoning from a hip implant, but I suspect doctors are careful to check their products are sufficiently coated before putting them in someone lol

Hopefully you don't work as a doctor, surgeon, medical researcher or materials engineer as you don't know much about the product. Try asking the materials engineers if they are using cobalt or cobalt chrome. Cobalt chrome and other cobalt alloys are routinely used in metal on metal contact as they are hard wearing/durable. Metal on metal contact means there is *no coating* on the joint region and the body is exposed directly to the metal. Cobalt poisoning is known from cobalt alloy implants. That you've never heard of it is just proof of your ignorance in the field. Wear particles do expose the body to cobalt and have caused toxicity. Many surgeons advise use of ceramic on ceramic or ceramic on polyethylene joints but of course the latter leads to microplastic exposure.

My favorite blue is Xylandian. From clorociboria aeruginascens cup fungi. I see it all the time.

Dude that was pretty dense but you pulled me through to the end. Billirubin and Bilverdin sound like a legal firm.

I don't know about anyone else, but the contrasting black & white in the "Awesome Socks Club" logo made it register in my mind as "Awesome Cocks Lub" at first, and then "Awesome Eocs Plub", and then finally, after way more time than it should have taken, as "Awesome Socks Club". My brain is dumb sometimes.

Anyone remember that song? I'm blue. It's depleting my bile. It's depleting my bile. It's depleting my bile.

Idea for a SciShow episode: Comparing the primary colours (yes I used a 'u' in colours) in the art world with the primary colours in the electrical and electronic world, explaining why they're different.

@turradaturra 3 года назад

Whenever you talk about structural colour, you should really talk about begonias (look for begonia pavonina to find the best looking one), they have specialised chloroplasts whose structure reflects highly in the blue. This will surprisingly enhance absorbance in the green. Look for the paper: "Photonic multilayer structure of Begonia chloroplasts enhances photosynthetic efficiency " to learn more about it. It's the only example in nature where photosynthesis meets the advanced physics field of photonics.

AsapScience uploaded a video of a similar topic, less than 24 hours apart. It's called why ancient Greeks couldn't see blue or something like that. It's very interesting also!

@KnighteMinistriez 3 года назад

Well than it's a good thing that my favorite color is orange. It's a lot easier to find that color. Blue is still pretty. I have some relatives that have blue eyes. Mine are not blue, though.

For a funny and more than slightly twisted take on the color blue in the art world, read Sacré Bleu by Christopher Moore. Kinda Carl Hiaasen meets Terry Pratchett meets Neil Gaiman... definitely more than slightly twisted!
