In the 70s, I did my senior project on Dictyostelium discoidium when I was a Biology major at Simmons College. At that time, undergrads were required present a thesis on original work in their senior year to graduate.

Used a vital dye to stain them getting beautiful photos of cellular restructuring during stages of the differentiation process with an electron microscope.

[@ShadowNinja2121]

I took a class and one unit went very in depth about this species. Some cool follow up facts. 1. When the “slug” eventually releases its spores, those spores usually carry bacteria in them to sort of “plant” into the new environment and than cultivate as a food source. It’s like a farmer bringing a herd of sheep to new ranch and it is wild. 2. When two different clone groups create a slug the slug is called a “chimera” 3. Cheating in this species in chimeras, as explained in the video, is actually one of the single craziest things in biology. The species has developed a handful of ways to combat cheating, for example some genes that result in a clone not helping produce the stalk cause it to adhere less to more altruistic clone types meaning it can’t “piggyback” as well and just falls off the slug. (There are A ton more crazy interactions for cheating and controlling cheating, but this is already too long)

The power of cooperation is with them. So many analogues to our societies, which can be considered superorganisms & even look a bit like certain slime molds (But not this one. Well, until we make space elevators to get off this finite rock I guess) Recent research into history in the field of Cliodynamics has even shown how Civilization began as humans got together to steal resources/defend themselves from other societies stealing resources (Typically farming vs non but also 2 farming with different culture). Which was important due to population growth. In our modern industrial/trading age though, things are different & wars are mainly fought for ideological reasons which makes them rarer. It makes sense, given that instead of genes, societies have memes, that is, culture/ideologies.

[@chezmoi42]

@Janitor Queen They are indeed slimy when in movement, and have long been a mystery organism confused with fungi. Though they can resemble molds, they are a totally different thing. Perhaps the most common manifestation is Fuligo septica, commonly known as 'dog's vomit' or 'witch's butter'. In its mobile stage, it forms a yellowish blob that feeds on rotten wood and plant debris, and is also often seen on grass or leaves. The slime molds, also known as 'myxomycetes', are fascinating, and have surprising properties. Check out an article called 'Collective behaviour and swarm intelligence in slime moulds', for a real eye opener.

[@mikedrop4421]

[@Animallovercomedian]

You are correct insofar as there are ameobae with such simple life cycles as that, but 'Ameoba' is not a taxonomic term.

[@WhatIsSanity]

@@The_Razielim They're microscopic predators?

[@The_Razielim]

@@WhatIsSanity That's one way of looking at it. The video showed a macrophage chasing down things in a blood smear, we often use Dictyostelium as a model for studying that behavior since a lot of the cellular mechanisms and processes involved are very similar, albeit simpler. It wasn't talked about much here, since their most interesting behavior is of course the aggregation and fruiting body development after starvation, but it's really cool how they hunt bacteria. Similarly to how he discussed in the video, when they are able to sense cyclic AMP (cAMP) and move towards the source during the aggregation-stage... during their vegetative/amoebic-phase, they will behave similarly in response to folic acid and other bacterial secondary metabolites released into the environment. They are able to sense the concentration gradient of the chemical in the environment, and move in that direction. A lot of the cellular processes involved in these two functions (hunting during vegetative growth, and aggregation during starvation) have a lot of overlap in the signalling and cytoskeletal regulation, since they're similar processes, just to different target molecules. A huge oversimplification, but I can't stress how cool these things are when you really look at them.

[@jakereich]

I spent a couple of years working with Dicty as a post-doc, and this was a good overview of much of their biology! One thing I think you missed: not only can they develop to a multicellular structure, but if this process is disrupted, the slug or mound cells will happily de-differentiate back to free-living cells. This is why Dicty are studied with respect to cellular reprogramming and stem cells etc.

[@Lmaonoshot]

He said that that chemical signal will draw in different species of amoeba? Is that true?

[@jakereich]

@@Lmaonoshot It's definitely true that different strains of the same species will be drawn in, and (without looking it up) I think it is true that some different but somewhat related species will also respond to the signal. When, for example, two strains mix and form a colony, some strains go more to the spore, and are referred to as "cheaters" . My (untested) theory was that there might be scenarios where it is actually advantageous to be the pre-stalk cells. For instance, since they are more easily shed from the slug, maybe they can de-differentiate faster if the slug encounters food.

[@emitaylor4094]

Where do the Dicty live? Is this just happening in the dirt all over the place?

@@emitaylor4094 Again, off the top of my head, they are most abundantly found in damp soil, forest floor, under logs etc. But I never collected Dicty from the wild.

Also in image segmentation steps of image/video analysis

[@anonymousperson8259]

I love learning new things 🤤 Sapio right here. Will Google that.

[@rikuaotsuki6353]

I know it's been a while, but I was wondering if you knew: is the Voronoi Diagram related somehow to the way packed dry earth and similar things cracks? It's a very similar pattern, and I imagine the cracking is essentially the result of the earth contracting around various points.

[@IceGoldDev]

​@@rikuaotsuki6353 I don't know much about that and I may be wrong, but I know that the cracking process happens because the moisture on the surface dries faster than slightly below surface, contracting the upper layer and causing tension that breaks the dirt apart. If we were to ASSUME it's based on the same concept, I'd have to imagine that as surface moisture evaporates, it does so in a non-uniform manner, with moisture gathering in small "pools" before fully evaporating. Areas farther away from these moist spots dry faster and contract earlier, cracking the dirt apart. But that's working back from the assumption. There are tons of examples of a voronoi pattern showing up in nature, like plant leaves, giraffe spots, turtle shells, mineral formations etc. While I can't speak to the specifics of each case, I'd imagine they all have something to do with some biological or physical process that involves the distance of each point from a number of randomly distributed nucleus points.

Ze, I always have a good laugh whenever you have posted a new video. Thank you for sharing this and for the science education. I'll check out the Brilliant link too because it sounds really interesting!

[@originalcosmicgirl]

I'm so amazed at how diverse, complex, and just downright bizarre life on earth can be. And this is just on this planet, right now. Imagine the possibilities on other worlds throughout the universe. Thank you, Zefrank, for bringing these creatures to us in a fun and accessible way.💖

[@SaintofFables]

I love how weird single cell organisms are. These guys make me me think that the first multi cellular entities were some of these ‘slugs’ that started to just stay as a slug and hunt bigger prey

[@roidrannoc1691]

I love how we humans tried to divide the world between unicellular organisms and pluricellular organisms. And then we found out things like that. Between a highly specialized unicellular colony and a simple pluricellular organism, the line is thin. Also sometimes some of our own cells are out there going back to unicellular. They just "want" independance and live as unicellular organism. We call them cancer...

[@syzygy808]

Thanks!

Dukey sent me. This is hypnotic, will watch more.

Usually Ze just complains to Jerry about his asking stupid questions or being confused, but I like this almost wholesome conversation they have at the end

[@lancewedor5306]

I must confess that Id like to date Jerry. He seems even more daft than Ze.

[@alantaylor3281]

Having never seen or learned about these amoeba I am officially blown away! I literally had my jaw resting on my knees in amazement. I now have to find as much information as I can about the microscopic life of unicellular organisms and biochemistry in general. I knew this in a basic way but, thanks to Ze, I have to pivot away from physics and QED which has always been my lifelong Love and start figuring out biochemistry. Thank you Ze, I love you 😀

[@michelles1250]

I recommend watching videos by microcosm, they have wonderful in depth informational videos about the micro verse

[@valkyrie1066]

Okay, your stuff is eye-wateringly hysterical. I SO enjoy your views on nature. Long time nature lover but I HAVE to listen to YOU tell it! My daughter is a big fan as well; and I hope for further little sprouts to show that learning things is fun and interesting. It's a happy thing. Love your perspective!

[@mononoke721]

It's both beautiful and humbling at the same time to consider that, in essence, us multicell organisms really aren't that different from single cell ones - we're all self-dividing/self-propogating, we just have different means of going about it. I do like the stuffed pizza delivery guy idea though, maybe we should try that one too!

He is, though, cherrypicking the material, only narrating the weird, very interesting and already funny animals/behaviours. It would be interesting to see how he would do a boring animal and when he also has to narrate the boring parts.

I really appreciate your consistency across the years. While the world continues to change faster, we still have you. Love ya.

[@Deacaros]

It doesn't. You just have more and more information to flood you and divert your focus. Living a 100 or more years ago, you would have a happy life, not knowing all the shit happening around the world. So...no achievement, you feel happier watching the shit go on on your phone-screen? Life is not worse, not better, it's still the same. You're just more comfortable now, yet forced to watch all the bad things around the world. They use the possibility to stress you by everything to be a GOOD BOI!!!

Thank you for continuing to make this series over the years, it is one of the hidden gems of youtube.

As a kid, I remember someone I knew using amoeba as an insult just because they were single cell. It's interesting to know they're not as dumb or worthless as I assumed as a kid. I really want a pizza now.

I’m so glad you’re back, Ze Frank. My friend and I would spend hours watching and rewatching your catalogue of videos every chance we got through the pandemic. until their suicide severed our little ritual. They loved you, and I’m sure they would have loved this one. Thank you for being here and providing amazing learning opportunities, humor, and wit. Also thank Jerry.

[@kathrynmceachern9503]

I'm terribly sorry to hear that you lost your friend, I also had a good friend kill himself during the pandemic. Hang in there, you are not alone. Ze is good for everyone, he's helped me cope with life every day, too. His voice is the one narrating thoughts in my head and it makes me feel better.
