Trick for imaging things that are too thick/break when a coverslip is applied: Cut a coverslip into 4 thin glass strips (diamond knife is useful, but it goes not necessarily need to be super precise). Glue a stack of 2 glass strips on each side of a slide (these serve as spacers). Apply sample in the middle. Place intact coverslip on top (resting on top of the spacers). If your sample still gets crushed, glue on additional spacers on top of the others. This is how zebrafish embryos are imaged.

I have a fun story about amoebas. Back when I had my first microscope around age 12, I started to get serious about culturing protozoans. My scope was just a cheap piece of crap Tasco, but it could do protozoa just fine, so I did a lot of pond, ditch and creek water samples, cataloguing everything I could find. Ever voracious for more and more to see, I decided to experiment with culturing by first taking a sample of water and then adding broth to it and seeing what would happen over several days. My nightmares awoke fully in me after I mixed some beef bouillon to a quart jar pond water sample and leaving it loosely covered in our barn in summer. I would go out every day, make a slide from the jar and observe on site, using sunlight with the microscope's mirror for illumination. Eventually, the jar took on the smell of dirty socks. One day, I stood there in the barn, squinting to see, and noting that nothing was visibly moving nor alive. BUT, I did notice a strange sort of speckle appearance to the entire sample, and it seemed to glisten strangely. Whatever it was, it was _tiny,_ at the limits of the microscope, and seemed to be _moving._ I upped the power all the way, got the best light I could, and tried again. Carefully focusing, I finally got it, and was horror struck to note not a few, not dozens, but hundreds, perhaps thousands of tiny, tiny amoebas slowly oozing around the sample. At the time, my mom was taking college courses for her RN license, and I was constantly reading her medical books, which often included graphic photos of various diseases. In one illustration, amoebas had infected a patient's intestines, which then breached their liver, diaphraham and infected the lung as well on a path of rampant destruction. There I stood in the barn, and it all clicked hard in my head - the smell of dirty socks meant at least _something_ was getting in the air from a jar full of amoebas scarcely bigger than red blood cells, and I was breathing that something in. I did a quick sketch of what I saw, then immediately dumped the jar and vigorously washed my hands, fearing that I would die of amoebic dysentery any day, lol. I also stopped the beef broth experiments entirely, despite that they had so often provided such amazing results. Now that I have a vastly better microscope setup, I really wish I had a sample of those tiny, tiny guys. I've seen plenty of common amoebas with it, but those were definitely something more interesting.

For now, here's this: Balamuthia Mandrillaris Balamuthia is found in the soil. While exposure is common, infection is very rare. Only about 200 cases of Balamuthia have been reported worldwide. It's thought that infection begins by the amoeba invading the skin or by inhaling airborne cysts through the mouth or nose. Symptoms are very similar to Acanthamoeba infection.8 Diagnosis is difficult and appropriate treatment uncertain, although the investigational drug miltefosine along with other antifungal and antibiotics may be used.7

[@zebratangozebra]

Amoeba have a "movement by flow" that I find hard to understand, it's fascinating to watch.

[@VoidHalo]

It's pretty simple at the heart of it. Just think of a water balloon. If you squeeze one part of it, the water pressure decreases in that part and it gets smaller. While the other end will see a rise in pressure and bulge outwards. If you imagine it has a sticky coating on it, it's not a huge leap to see how it could move along by sticking the bulging bit to the ground while releasing the bit that's being squeezed from the ground. Amoebas just have more control over this squeezing and bulging mechanism, so they can squeeze or bulge specific parts of themselves.

[@Ryan-tz7sx]

So, I'm not a biologist but from my understanding they use microtubules to extend their cell membrane in the direction they want to, then push their cytoplasm into that extension. Then the rest of the cell follows. But I'd recommend googling for more accurate information.

8:17 Might it be better to ask "if they are better off" without mitochondria? Evolution tends to get better, but that's a trend, not a constant :) Fascinating hypothesis, which is probably right, however!

[@japooskas]

Given that life needs energy to sustain its order .. anything which can provide it will almost always be a benefit. In their case, maybe its their inner bacterial flora that may provide some energy source/system that is sufficient enough that they didnt have the need to keep mitochondria incorporated too. Mitochondria do play a role in cell death in our bodies. If they lyse, the cell is usually doomed to die too from the chemicals they release. Maybe amoebas were better off in some specific aspect of the evolutionary barter trade system. Fascinating indeed!

[@fakecubed]

Who knows if they're better off or not. Things happen and it's chaotic and random. That amoeba might've lost its mitochondria somehow, and managed to survive because of some other event or circumstance, and went on to reproduce and start a new species, but that doesn't mean it's better off. Life isn't about making choices to be better off, it's about surviving the bad things that sometimes happen just long enough to reproduce.

[@andybeans5790]

There are plenty of examples where "losing" stuff is advantageous, like vestigial features. Birds "lost" their teeth, which was advantageous because that reduced incubation times where both eggs and parents are at risk.

[@TheNomadic69]

You asked about the cell that lacks mitochondria. I cannot answer why not having mitochondria may be advantageous. However, I run evolutionary algorithms and study the evolutionary process as a form of unconstrained optimization. I can tell you that there may not actually be an evolutionary advantage to not having a mitochondria. It is possible that the species exists simply because the mutation wasn't bad enough to make it go extinct. The natural selection process is high-dimensional and highly nonlinear (math speak), meaning that it cannot be described accurately by phrases such as, "survival of the fittest"

[@marxtheenigma873]

I have a video request. I want you to talk about the micro marvel that is the bacterial flagellum. It is not connected to the bacteria and still lives. My friend is into speculative biology and has designed a creature with helicopter-like blades on its serpentine body. Not attached, like the flagellum. She looked up the issues and believes she has solutions to a few. To make them spin, this creature creates electricity. Lubrication liquids greatly cut down on friction. And the spinny parts reconnect to the rest of the body periodically so they can be resupplied.

[@samiamrg7]

I don’t know if James has the equipment to get good images of (most) bacteria.

[@samiamrg7]

Speaking of speculative biology, this reminds me of a section in the book “The Risen Empire” where some microscopic surveillance drones have to sneak passed countermeasures that take the form of microscopic cyborg organisms sprayed out of a can by humanoid cyborg commandos. The organisms are described as having a sluggish propeller keeping them in the air, a simple “arm” to grab and weigh down adversaries, and sensory hairs. Closer to their target, the drones find larger organisms that have multiple propellers and multiple arms, as well as more dense and more advanced sensory organs. The organisms are designed via directed evolution and thus change rapidly, so no two cans of the things are exactly alike same.

"Our bodies, after all, are built out of the lessons that nature learned with them." This kind of statement drives me crazy; it reveals a fundamental misunderstanding of evolution.

They are every bit as evolved as we are.

@@bjornolson6527 They aren't our ancestors in any manner, not even metaphorical. They are our cousins. We share a common ancestor. THAT ancestor had less time to evolve than we both have, but all current amoebas existing today have had the exact same amount of time to evolve as we have. You could in fact argue that they've had *more* time to evolve relative to humans because of their significantly shorter generation time.

[@bjornolson6527]

Erica Rettig Your assertion implies that this “common ancestor” no longer exists.(?) At some points in time, an off-shoot with a mutated genome found a niche in the ecology, and continued apace of the original. This allows the concept I put forth. Subsequently, further intermingling and more random mutations occur resulting in the variety of life we have today. opentreeoflife.org Homo Sapiens and Phylum Amoebae are both eukaryotic organisms.

[@bjornolson6527]

Who’s to say the ones we’re looking at now aren’t genetically identical to the (an) off-shoot that resulted in primates? They simply “found their niche” really early. If it’s working for them, and didn’t get wiped out by some competitor or environmental change they couldn’t handle... Theory of evolution allows the POSSIBILITY (and mechanism) for species development/differentiation. It doesn’t mandate change.

Hank Green is like scientific Mr. Rogers- so calming and friendly, but could explain anything to you.

[@dreamsprayanimation]

Kind of funny his last name is Green considering he spends so much of his time literally looking at what makes plants green.

[@BohdanChub]

Make "how we shoot" video, please 🙏

[@djoseph2475]

I second this.

[@PursueTheUnknown]

Great video, this microbiology content is top-notch.

[@dr.glutamate8762]

Pelomyxa's an interesting one. They clearly have some ability to tolerate oxygen, but they're anaerobic. They do have organelles called hydrogenosomes that are derived from mitochondria, so they haven't lost them completely. Another odd thing about them is their flagella. They're short, rigid little things that don't beat, and have highly irregular arrangements of microtubules, even within the same cell.

Picked the right month for this one.. * tips an imaginary hat *

[@gp-1542]

I love how casual talk about brain eating creatures

[@maythesciencebewithyou]

I doubt they are better off because they lost their mitochondria, it's probably so that their ancestor just lost it by accident, yet it's descendants still managed to survive, but didn't manage to get a new mitochondria.

Like other PBS channels such as Spacetime, this is an oasis of intelligent and interested commenters.

Hank's voice is smooth as butter in this video

[@theyassinoo70]

I like to watch your videos before sleeping. Its amazing to explore the microscopic world

I love this channel! Regards from Italy

I have NO IDEA how I got here or WHY it was suggested to me, but... I enjoyed my time watching this video. Not sure how this information is going to be useful, but... entertaining it was...

[@6Twisted]

I had no idea the commentator/writer for this show was Hank Green from Scishow...

[@justintime970]

You describe music so well! 😉

[@crazycatcrazyschool1779]

I like how I got a ad about thawing cells before the video.

[@macfrauer]

A Pelomyxa may not need mitochondria if it finds another way to obtain energy or the energy consumption is so low that it can be created and expended simultaneously and independently.

[@ffejkk37]

I'm so chilled out after watching this.

[@noalear]

Mr. Tardigrade is a supporter of this show. He must be doing very well for himself.

[@owenreynolds4781]

can't wait to get baked and watch these videos

[@goldenfloof5469]

Hmmm, interesting. Wouldn't want to be one though.

[@pigeonfowl474]

I wish I was a simple-minded unicellular blob that didn't have to worry about school or social interactions.

[@Mr.Isquierdo]

@@carissstewart3211 at least scientists pay attention to them

[@wilddogspam]

@@carissstewart3211 they're also pretty much immortal as any amoeba is indistinguishable from it's descendants, because when they divide there's no longer an original, but one being that turned into two. So what I'm trying to say is that even if they appear much more fragile than us with our multicellular might, they're kinda a lot tougher.

[@goldenfloof5469]
