Oomycetes are one of the more unusual-looking microbes we’ve seen in the microcosmos. It looks more like a coral reef painted by an artist inspired by Gustav Klimt and a pile of trash. And if you saw that painting hanging in the museum, you might pass it by without thinking much of its subject.

@davidgould9431 Год назад

Except "a fungi" is nonsense. You have "a fungus" and "several fungi". And the g is still supposed to be hard (g not j) in fungi (edit: so your joke works, haha). Latin ftw, but note that the Italians spell the plural funghi, which keeps the g hard. Don't get me started on "alji". The g is hard: one alga, two algae (edit: al-guy). Hank, bless him, is obviously American. Pronunciation of foreign words isn't a strong point. Dammit, I'm British and could say the same of most of my compatriots. Edit: and I should say it about me, too. There are many, many languages I have no idea about and a lot of words I don't know in the few that I claim to have some knowledge of. I have no idea what I was thinking when I wrote that drivel last night.

I think the most compelling and plot-driven use of microscopes is in the 1971 sci-fi movie Andromeda Strain, based on the novel by Michael Crichton. Scientists are trying to identify a possible organism brought back from space. My favorite aspect of this are the mistakes that are made as fatigue starts to effect the scientists.

I am often left with this tension between questions left unanswered and the barely understood in your videos.

I feel the need to grab a microscope and find out for myself if there are oomycetes lurking around up my nose or somewhere. Truly excellent!

What if horizontal gene transfer between two non-related lineages was so intense that molecular evidence would group them both despite not being a real group? Could this ever have happened in the past? (Maybe with prokaryotes?)

@TheRedKnight101 Год назад

Normally you don't look at the whole genome of an organism to classify it. There are certain genes such as CO1 or 18S/16S that you would compare as those genes mutate at a very slow rate because they are vital for an organisms existence. It is best to compare multiple genes just to make sure. Genes that would be obtained via horizontal gene transfer could be used to differentiate at the family or genus level but it depends on the rate of mutations of those genes.

@thomassontag4270 Год назад

Yes, there are microbes with DNA that mostly came from horizontal gene transfer, but that doesn't obfuscate their ancestry (assuming you were able to look at this thing's DNA, which isn't all that difficult). Basically, we only look at 16S rRNA (a really important sequence that all life has) to look at ancestry and ignore the rest of the genes. This method doesn't look at horizontal gene transfer, so horizontal gene transfer doesn't mess with trying to figure out "who the father is" all that much. But of course, if most of the DNA in a microbe came from horizontal gene transfer, knowing where one gene came from won't give you a clear picture about how this organism works.

@thingamabitch Год назад

Potatoes being inedible only caused a famine because potatoes were all the Irish were allowed to farm for themselves. England took all of their other crops and took this artificial famine as an opportunity to commit ethnic cleansing by evicting everybody from their homes, so they could turn Ireland into lots and lots of farmland.

@UniDocs_Mahapushpa_Cyavana Год назад

Class and cultural cleansing seems like a more likely motivation, as pre-Irish-Potato-🥔-Famine was very culturally different from England ☕, much more so than now. And humans tend to be more trigger 🔫☠ happy with cultural differences than ethnic ones. That is a pretty universal trend, even more tolerant nations are like that.

Yep. As an Englishman I am ashamed. Modern-day Americans might want to ponder what the point of killing all the bison was. Not to ensure native Americans starved? Surely not! The trouble with high horses is that they offer a long fall. OK, you might be a penitent English person or an infuriated Irishman (can't blame you) or an Irish-American who's soaked up all the vitriol. Or someone else. Whatever: what we English did to the Irish was unforgivable. Mind you, we did lots of unforgivable things to most of the world. I'm really not proud to be English. Luckily, I'm 62 and, in cosmological terms, I'm pretty much gone already, so I can't do too much more damage, even by association.

@PeridotEX Год назад

Something i've always wondered about - is there a reason that unicellular things like yeast are considered fungi, while things like algae and ameoba are considered animal/plant-like protists? Are unicellular fungi similar enough to their multicellular brethren to share a kingdom, or is it a relatively arbitrary decision?

@Dragrath1 Год назад

To answer this it turns out that at least in some cases yeast can depending on the environmental conditions revert/reorganize into multicellular hyphae while some typically hyphae network fungi can opportunistically revert/change into a yeast like form. So while some fungi are almost always yeast or hyphae others blur the line such that its hard to differentiate the two. In fact lab experiments have even shown that through artificial selection they can force generally obligate unicellular yeast to reevolve multicellularity in the lab. Genetically there is good reason to believe yeast are the result of secondary unicellularity/independent living thus any group of fungi which excludes yeast would be paraphyletic in the same way that any group which contains monkeys would be paraphyletic if it excluded apes. Does this help answer your question?

@rachaelkenworthy6044 Год назад

Short answer, yes. Things like digesting their food outside before absorbing it, having cell walls and how they build them, amongst other traits do group single celled fungi separate from algae or amoeba. But when you get into where exactly to draw the line between more similar single celled organisms scientist are still researching and debating.

@MrTimjwilson 10 месяцев назад

It would be great if James could do a definitive video [with his great equipment] delineating the morphological differences between oomycetes and zygomycota fungi > Mucoromycotina species too perhaps. These distinctions are important for farmers/growers using liquid extracts verified by microscopy. These extracts are applied to soil and plants to enhance growth. Thank you James for your good work.

@flamencoprof Год назад

WRT horizontal gene transfer, in 2015 I learned that DNA can shuttle between cells in an animal. Specifically, mitochondria can migrate between cells in the same body. I also learned that Mitochondria are in a constant state of fusion and division inside the cell, which seems to tie in with that, making mitochondria seem a lot more autonomous than I had been taught in late Sixties Biology class at school.

@anomalousentity Год назад

Horizontal gene transfer between evolutionarily close/distant multicellular life could happen via a viral intermediary. I'm thinking something similar to how we use tobacco mosaic virus to heterologously express foreign proteins of interest in plants.

Howdy, this will probably be long but oh well. I recently have been getting in to microscopy but I'm having trouble deciding what I should do. I don't really know what, or how, to study, what I should be looking for, what sort of things need more researching, etc. It's so hard to put into words. There are certain species that look like one another but are different, lots of things are unknown, even the same species can have certain "strains" and it's a lot to take in. You could finish your giant game of guess who and still be wrong! I don't know, it's just a bit confusing to me. If anyone made sense of that I'd love to read the replies, thanks!
