Trying To Solve Some Micro Mysteries 

When I was a kid I thought the humans figured the world already, there was nothing to be discovered anymore, it was done. As I grew older, I realized we are still completely surrounded in mysteries. In the past few hundreds years, all we did was put words on things and phenomena, but we don't truly understand anything at the deepest level, not even the most basic subject. Sometimes I like to play the ''Game of how''. You pick a subject you like and know well, and you ask yourself (How is it doing this) . By example (How is gravity pulling me down). When you find that the answer is X, you ask yourself (But how is X pulling me down). When you find that the answer is Y, then you ask (But how is Y pulling me down). You will most likely get the answers of the first 4-5 questions, but eventually you get into a very obscure world lol, you can't answer, and no one can. I like it that way to be honest. This world is still a complete mystery folks :) Isn't it amazing? Keep your eyes and your mind open.

I love how Hank has set the tone for this channel so much that even when it's not him, ppl narrate slow.

I love this channel. I've watched every single video for several years now, mostly on my TV where it's difficult to leave a comment. This channel represents everything that is revolutionary and beneficial about the internet. A small team of amateurs, working from home to produce a glimpse for the rest of us into a world only available with modern technology, in an entertaining and enlightening manner. You will have one million subscribers before long! Deservedly so. I tell people about this channel all the time. I will never look at any drop of pond water the same way again. Like most people, I had no idea that the microscopic world was teaming with that much life! Every time I go to scrub out the scum lining the container that holds my dentures, lol, I think about the billions of ciliates, parameciums and unseen living algae growth that I'm killing, thank you very much Journey to the Microcosmos!

Im sick rn, so watching a whole bunch of microbes is making me feel so much better lol

6:00 YES! I had figured it out! Oh you do beautiful work at Journey to the Microcosmos. Thank you from the bottom of my sleepless heart at 3AM California time ;-)

Every time I play a new video from this channel I hope it's Deboki hosting, I'm so happy right now! (I mean, I love Hank but I don't get enough Deboki in my life, considering she doesn't have 300 different channels/podcasts like Hank!)

I will never get over how beautiful the microcosmos is.

Didn't look too closely at the thumbnail, so I was genuinely shocked when I noticed the cloudy material in the reverse footage begin to take the shape of a cell. I'm enraptured with curiosity!

I have an idea as to why this critter had both purple bacteria and algae - what if it was more of a wanderer than most, or maybe its pond of origin had an unfortunate frequent habit of drying up at unpredictable intervals? In a situation like that maybe it would spend MOST of its time in the bottom, low-oxygen and cozy with its purpley friends. But when the water level gets too low there'd be sunlight and probably more oxygen, and less of the materials the P. tenue would normally need. So then, the algae come into play, and their effort helps feed the host AND (in a secondary fashion) the bacteria, so that everyone still gets the good deal until the water returns. I don't recall if purple bacteria are ever parasitic/predatory, though. Or for that matter if algae can be harmful to a host. That could be another explanation, though it seems like if that IS a thing, it'd be more common. An arrangement of three-way symbiosis though makes pretty good sense in very specifically difficult conditions, and makes me think a little bit of tidepools and the unusual living habits of the creatures who've adapted to them. But how common are fresh water "tidepools" as it were? It wouldn't be like puddles, nor like the edge of lakes; it'd have to be some kind of medium-shallow, partially still pond, something that gets "topped up" by rain, but infrequently. Or maintained by human action but in a real inconsistent way. Such bodies of water can't be all that common, and so such creatures as this P. tenue with its extra passengers can't be common either.

How flexible can endosymbiosis be for microbes? does each bacteria need a specific set hosts for it to work? which kinds of microbes are more likely to pair up in endosymbiosis?

Deboki has such a nice voice for this channel 🤗

wonder what killed the little fella; looks like it was doing well one moment, and then one end just started leaking and the whole membrane fell apart

I like this a lot.

A couple years ago, there was these kind of algue in the lakes in Quebec, Canada. They called it the "blue-green" algue. It was considered a health safety issue, and closed some beachs and warned us, not to go in the water when these algue where seen. They said it was caused by the rising water temperatures and by the acidification of the waters... We never knew what caused it, if it really was dangerous for health, and why they suddenly stopped talking about this...

Lovely video. Beautiful narration!

Shaq and Kobe on the Lakers 🤝 Two different pigmented endosymbions inside a larger cell

_Pseudoblepharisma tenue_ are quite fascinating to me and IMO more interesting, precisely because it's host to two distinct photosynthetic organisms - one of which is a secondary endosymbiont which is, itself, host to plastids. What's more fascinating to me is that it has *purple bacteria* as endosymbionts, and unlike chloroplasts, these aren't dedicated/strict photosynthesis/autotrophy organelles.

We found two ciliate protozoa who are in love. Science still can't explain why microorganism can find love but I can't.

No offense, these videos are amazing for helping me get to sleep. So calming, so relaxing, so informative.

0.56 My boi ( the small, white, fast guy on the lower left) just wandered into the neighborhood, took a tour and noped right out of there!

Ooh, finally! Some attention being brought to _Pseudoblepharisma tenue._ I was going to suggest a video on these things at some point, but here it is now anyway. Nice!

The relationship between the algae and the bacteria in their host is a perfect analogue of what's happening in the world of humans. As above, so below. We can learn a lot from the life all around us, and how we coexist.

I think with that cell, the bacteria and algea aren't conflicting, they're complimentary. And their preference for low oxygen I think confirms it. By having the oxygen consuming algea, the anaerobic bacteria is kept safe from surrounding oxygen. But the algea can only consume so much air, so they'd choose somewher with low oxygen, so as to not overwhelm the purple bacteria

Cool. Ty

"And yet they seem to do just fine" -- then the host dies.

I love the idea that life may have began as a symbiotic blob instead of discrete competing cells 🎉 . That’s the feeling one gets from psychedelic theogony; i.e. everything is connected

"And yet they seem to do just fine." And yet we all just watched it explode.

Nature is like my anatomy professor back then who was infamous with his exams. Imagine this, medical trays containing muscles or organs and a colored pin means identify the part. This was time pressured. He would jumble muscles, veins, arteries etc. till its unrecognizable. According to him, it was a simulation of fatal accidents. Very few passed his exams. Once you get used to his masterful artwork you will get it eventually. Just like mother nature, in time all will be revealed through scientific research. Thanks for reminding me of this. That's why I watch your channel.

Folie à trois! 😄

It seems obvious to me that if you want an oxygen-free environment, you need an oxygen vacuum to remove it. Thus the algae serves to remove the oxygen. In other words, the bacteria is herding the algae for terraforming local environments. This might even mean that they have targeted particular algae for survival who can both get great benefit from oxygen, but also survive in low oxygen environments.

Darkfield microscopy only please from now on. All the other methods are the equivalent of seeing humans on x-ray instead of ambient light.

The micro Barney was awesome. This is the first time I've seen purple & green compliment each other.

Want more of this plzz

This is so cool! I’m writing a story where a planets plant analog evolved from a creature like this!

I remember looking at pond scum under a microscope in a high school biology class. I saw some small creatures, paramecium, I guess? But what I saw was a large elongated single cell organism that had a most unusual feature. At one end of its body was a strange organ that looked like a sphere that was rolling around and rotating in all directions as the animal moved around in the green algae. It was definitely a sphere and was definitely rolling in all directions. It was really, really weird. They were fairly large in comparison to the other animals, there were more than one and other students could see them too but nobody seemed to think anything was weird other than me. I have never seen any mention or depiction of this creature since then nor any explanation for what I saw. The teacher was oblivious and more interested in flirting with the female students than talking to me about what I was seeing in the microscope.

As a non English speaker, today i just realized that "Master of microscope" means that someone who operate the microscope and not bragging about James's mastery in using it. xD

Wait wait... what did the bright UV light do to the pelosigma, exactly?

Maybe a Blepharisma evolved to gain an algae symbiont. Then, later, a line evolved to live in a low oxygen environment, so it used the same machinery to house the algae for the purple bacteria. But they kept the algae, because of non-photosynthetic benefits to the algae. Being much more complicated than the bacteria, as Eukaryotes, the algae has much more complex and potentially helpful machinery. The algae probably still photo-synthesises, but that is less important now. It is like how barely flying birds 🐦 and insects 🦗 can exist, because the clades are basally flying, so it doesn't need to be a big lifestyle thing to have enough selective pressure to gain it. It is just there as standard.

I think the host crashed because it was distracted by the "kids in the back seat". Then, the "kids" tried to figure out, "Do we continue on together, or go our separate ways?"

Bacteria is shown these things also! 😊❤

All I know B bloods have super cells that are far more advanced than most humans can imagine seriously

I’m surprised you didn’t bring up the possibility that because it munched on the algae and sulfur bacteria, this may have caused it to have a chemical reaction inside and was the cause of death for the organism. Very cool tho thanks for sharing

It's November the 13th, 2023 and I am watching this clip while eating my microwaved oatmeal topped with cinnamon, frozen blueberries, extra virgin olive oil, almond milk and a sliced banana. As I am enjoying my breakfast and watching this video, all I can say about this video is that it is absolutely, B E A U T I F U L.. ❤ That organism dying at 8:00 and slowly falling apart, spilling it's microbial contents reminded me that we ALL eventually die. Sometimes in the fast pace of life and being an adult, you totally forget about your interests when you were younger and when I randomly decided to watch this clip on my day off today, it reminded me of my love and fascination for microbiology in my late 20's... 🥺😌🥰😥

Why does it fall apart like that so fast after it dies?

Can the purple bacteria survive outside the host? What happened to them?

Hm, the pseudoblepharisma died. So I have the suspicion that the roommates didn't live togheter so peacefully after all...

When the pseudoblapharisma dies it appears to abruptly die all over its body more or less at the same time. Like all those purple bacteria decided together to kill their host.

It's like three dogs stuck.

If algae and purple bacteria thrive in very different environments, how can pseudoblepharisma collect both? can endosymbionts be passed from host to host? or even host to its offspring?

maybe the spathids just wanted a little extra fun

Do my ears deceive me ? She said "James" with out adding 'Our master of microscopes'.

Purple bacteria that dont use sulfur? How does it funtcion then?

Is Hank doing better?

Now think of bacteria in humans. And then take a step back, and think about humans and trees living on continents. Then another step back you could realize, that there are continents and seas. And further, there is this planet....

👋

...no mystery; they are having a 'three way'; hmmm, I know about that....

The usual narrator does such a great job and is so emphatic and relaxing. This is my first time hearing this other one and it sounds like they’re just going through the motions reading a script. Usually the videos have so much feeling. But this one lacks it entirely

Guys posting 58 minutes from when i have to work is cool and all but its just down right creepy coincidence

Science doesn't know why someone would have a treesome? 😏🤔😅

What happened to Hank ?

Didn’t knew spathids have some kinks

rice and peas

Love the channel would watch more if you stopped pushing the adds.

Pseudoblepharisma thrupleusi

Why does your microphone sound like it's magnifying into your tongue

Get conguated

YT rules can be a bit specious at best. Human porn = BAD Bacteria porn = A-OK! Message? 🖖😉👍

I solved the spathids question. The males have two reproductive organs. What a life 😅.

How do we know that the bacteria were in a symbiotic relationship with the P. tenue? It looks to me like the bacteria invaded and killed it.

I'm looking for a microorganism that can consume salt NaCl as a way to purify sea water. Any one have any ideas?

Third

I have no issues with the new narrator and don’t miss Hank Green at all. I have no issues with the new narrator and don’t miss Hank Green at all. I have no issues with the new narrator and don’t miss Hank Green at all. I have no issues with the new narrator and don’t miss Hank Green at all. 😭😭😭

1:58 Thank you for scientifically proving inclusion is not always a good thing even at the microscopic level. 🤣🤣🤣

hot

To bad it didn't pass on its new gens.

I did not enjoy the back and forth context switching for the sake of suspense

Vocal fry and uptalk made this a little difficult to listen to.

We pretty much can’t explain anything so nothing new there.

Its obvious to see that the Palasigma are all coming together to protest at the genocide in Palestine

This channel used to be enjoyably informative. Now it is just quirky / kooky and verbose - trying to be amusing and using a lot of words to impart very little detail or explanation at all.

Oh god the vocal fry makes this unbearable to listen to.

Too convolutedly told. I couldn't like, got lost in excess of "literature".

It might help the channel, which is attempting to inform people on a scientific level, if they didn't narrate their videos with someone who seems to be striving to show off her "Valley Girl" impression.

Great content, but this video has the WORST music. All I hear is "BONK BONK BONK BONK BONK BONK BONK BONK" and it makes this video unwatchable.
