Dope Tech Episode 2

<<@marumiyuhime says : there was certainly an ozone layer during the silurian. ozone is a result of the oxygenation of o2 to form o3 this processes has been ongoing prob since 650million years or so. im not saying it was the samme but it was there. thats y i have 2 degrees one in earth space science the other biology.>> <<@MSSSpecimensScience says : the moonlight detection hypothesis makes sense, but wouldn’t a full-body light sensor also make them more vulnerable to artificial light pollution? I wonder if urban scorpion behavior has shifted because of modern lighting.>> <<@LXDNG says : Have been keeping scorpions for a long time. I noticed that freshly molted scorpions do not glow under UV light until their exoskeletons harden. Wonder if is a key to the mystery or if anyone can explain thus to me.>> <<@HyungnamGu says : Exceptions and Non-Fluorescent Scorpions: Cave-Dwelling Species: Researchers found that certain cave-dwelling scorpions do not exhibit the typical fluorescence, a, evolutionary adaptation to their dark, isolated environments. Chaerilidae Family: Studies have indicated that some, if not all, species in the Chaerilidae family may not fluoresce under UV light. Post-Molting: Scorpions must have a fully hardened cuticle (exoskeleton) to fluoresce. Newly molted scorpions, which have soft shells, do not glow until the cuticle has completely matured, a process which deposits the necessary materials (specifically in the hyaline layer). Baby Scorpions: Juvenile scorpions often do not show fluorescence until their first molt.>> <<@LordofRobes says : Polymorpins or soemthing probably butchered the name>> <<@matthewexline6589 says : I'd like to share my theory on animals that reflect UV light. If an animal's skin absorbs UV light, its cells are more exposed to that UV energy than if the light were reflected , because absorption means the energy is taken in, exciting molecules and potentially damaging DNA, whereas reflection bounces it away, reducing cellular exposure and damage. Darker skin generally absorbs more UV, while lighter skin reflects more, but the absorption process itself signifies deeper cellular interaction with the damaging radiation, highlighting the importance of protective pigments like melanin. Exposure to UV light significantly alters both DNA and RNA, causing direct photochemical damage like pyrimidine dimers in DNA and various modifications in RNA (photochemical, oxidative, crosslinking) that disrupt their function, trigger repair mechanisms, and can lead to mutations or cell death if unrepaired, with RNA often acting as a rapid signal for the cell to initiate a damage response. So basically I think that animals (like the ones listed in this video, not JUST scorpions) use UV light as a way to keep their genetic traits adaptable. Like how human beings have exposed plants to radiation to increase crop diversity in order to perform super-performant selective breeding, I think that animals that absorb UV radiation do so to promote genetic diversity. This might explain why some of these animals have evolved SO MUCH compared to their contemporaries. For example, just think about the platypus and the scorpion (mentioned in this video for absorbing UV and emitting normal light) I think it's notable that these animals have evolved more highly-defined traits compared to most other living beings, thus perhaps supporting my hypothesis. Just my thoughts.>> <<@warkentien2 says : 3:50 I'm fighting with AI, allegedly, this metal stinger information is false. Specialists, please weigh in.>> <<@AndrewTheFilipino says : You can sense light via heat no?>> <<@adrenalmedulla says : How do you know the marine UV blocking varnish didn't attract the insects more than their florescence would potentially have? Seems like this could be a confounding factor.>> <<@peterjackson2632 says : Try putting your hand in front of a filament light bulb and you will feel the heat. In 1968 when the light experiment was performed on blinded scorpions to find out if then can see without their eyes, the lamps would have been filament lamps. These emit a ton of infrared radiation so it was likely that the scorpions sensed heat and not visible light!>> <<@محمدجوادالهامی says : If they absorb UV and radiate visible light, why are they not glowing in daylight?? Isn't the Sun just a big UV lamp?!>> <<@Lefty_Onenut says : Scorpion hunting is a lot of fun! But remember, rattlesnakes and other venomous snakes do not glow in UV light. Use a standard headlamp while walking, turning it off only while standing still to scan with your blacklight occasionally. Stay safe!>> <<@ozziejule69 says : Can anyone pls give me fish on fisch? Username:Miggymoo12312 or fischaholic2>> <<@baxterburgundy9284 says : Ultraviolet TORCH?! What are you British?>> <<@baravital24 says : maybe it's a defense mechanism against reptiles? detect light looks promise>> <<@DeleteKernel says : "Scorpions can detect light with their eyes covered" Scorpions are small, therefore shining bright light on them should probably meka a big difference in terms of heat. Consider that on a bright day humans can feel whether sun shines on them or not.>> <<@jsalienisticways says : We're (Scorpios/Scorpions) are like a Solar Power panels with legs and 8 eyes. I mean the full moon vs the new moon results further backs up my theory.>> <<@toaibankhrawborjyrwa7148 says : So scorpions change their color at night.>> <<@ianmarriott4137 says : I know this comment will probably never be seen but has it occurred to anyone that the fluoresence is used to attract or find a mate?>> <<@Fuzzelism says : It's crazy how much my charcter acutally resembles the behaviur of a real scorpion 😂 Like the fact that they starve themselves for long periods. I'm someone who can sometimes just go a few days without really eating anything, cause im just not very hungry 😂 Also they're loners, like myself. And the different moon phases have a big impact on them. To me I also always feel a greater energy on full moon nights and I always dream a lot and remember almost every dream in this night. And generally I'm a night owl 😂>> <<@Grinchfeast says : Would be awesome if Ticks were fluorescent>> <<@M4dniss says : I've decided just to start telling people my scorpion consumed radioactive material as a baby>> <<@jonharson says : CIA scorpions; They glow in the dark.>> <<@laomisaavedra says : Charly García, La lógica del escorpión !>> <<@ryanap8396 says : So Perry The Platypus is accurately colored>> <<@BhavinVyas-xy8ey says : I have a pen if I put a dot I can't see it but it comes with a uv light if I shine it on I can see it I can draw a lot of pictures>> <<@curious_gage says : 5:00 they probably felt the heat from the lamp>> <<@maximtsankov9445 says : Can’t the 1968 light detection experiment show the results because of the heat? Also they might use their photon detection ability to hide from the sunlights heat.>> <<@lefaraone03 says : My hypothesis: It just looks cool😀>> <<@Thathikingfoo says : 6:44 " go in ur home" *YEETS THE FU*K OUTTA HOMIE*>> <<@magister343 says : The proper plural of platypus is Platypodes.>> <<@ecuanis89 says : Mother nature is amazing>> <<@pappa6085 says : it's camouflage and not camoflauge>> <<@chrisnewman8348 says : His final conclusion was illogical, as I understood it. The logic went something like "when it's a full moon, the UV light from the moon will cause the scorpion to fluoresce (radiate visible light), which the photo sensor in the tail can detect to recognize that the moon is out." Two problems with this: moonlight has much more visible light than UV light, so just visible light from the moon will light the scorpion to be much brighter than any fluorescence would. And, much brighter than that is the moonlight hitting the tail photo sensor directly, so the scorpion would detect that!>> <<@T.A.123 says : Do you know? Bear Grylls ate them!! 😅>> <<@_Stalc_ says : Kind of reflects their predator the solpugids or even centipedes to hide into dark and damp places to seclude themselves from direct sunlight. Besides scorpions, isopods also seem to recluse themselves into darker areas and originate in the ocean as well. Scorpions possibly did the opposite with light to find prey in sufficiently dim places away from sunlight the way people look under rocks knowingly there might be something where they're hiding. The iron and nickel bit is new to me and incredible, it would allow to kill hardier robust prey like beetles and another organism capable of utilizing metal externally from it's own body like; shrews, scaly snails and certain large spiders/tarantulas that do the exact same thing.>> <<@amberhawksong says : Really enjoyed this vid, scorpions are so cool.>> <<@cleitonoliveira932 says : Scorpions that are really hungry come out. That means this man spent his entire life doing research on loser scorpions, not the winner ones that have higher chances to pass the genes.>> <<@dilshodasrayev6241 says : where can i get the full text of this video ?>> <<@deepakjoshi664 says : These species absorb Harmful radiations. This is their role in ecosystem. Further predator species gives vibrations of elixir to envioronment. Mongolian people says when pack of wolves are near to their live stocks, they less fall ill. And the guy who predicted all this in 1970s had also said whenever humans wants to settle on Moon. War are raged on Earth. Artemis program will invite destruction of USA.>> <<@Monhol says : "Jesse we need scorpions">> <<@versacebroccoli7238 says : 5:15 I bet those lamps were hot though.>> <<@Alraithification says : i really love him telling us about the hypothesis that proved out to be wrong and the thought process behind it>> <<@L.J.Designs says : Diurnal, actively - hunting, scorpions, especially in desert habitats makes the fluorescence ability more complex. They must be experiencing a sensory overload (whole body acting as a light sensor), potentially akin to us looking into the sun (not that I assume the idea that I'm entertaining is a fact). I think keeping this in mind UV- protection might be more likely. If I was religious I would have thought it's for humans to walk safer in the dark, with a UV light but alas...>> <<@FactCrux says : Wow...Very nice 👍 we tried scorpion Hunting in India, I would appreciate it if you could have a look and provide any expert comments or suggestions. I Hope you will like that 😊 Thank you.>> <<@seldom_bucket says : Owls?! Why? Explain now!>> <<@youtubynotme says : a very powerful alien lost a child to a scorpion and genetically altered them to be visible. a few species were missed>> <<@jimmyday656 says : Go back to the owls>> <<@Loagun says : Scorpions capture a human, paints the human's eyes black to make it blind, and then puts the human under a giant UV lamp? The human moves into the shade. Confused over how the human was able to determine the light from dark after being blinded, the Scorpions ask the human how it knew it was under the light? Human: because I felt it.>> <<@larryd9577 says : I reckon that in 1968 the light bulbs used were not LED, hence they emitted not only light but also a good portion of heat. We are able to detect it, does that mean that we also have an "extraocular light sense"?>>
