I think the most striking thing about the images in this video is how noticeable the absence of foreign organisms is. The blood is very, very, VERY clean and homogeneous compared to, of course, the scummy pond water, but still it is very appreciable how well-maintained the environment is.

I hope James can get a sample from someone with sickle cell, this episode reminded me of that and now I'm looking it up to see if all or just a portion of the cells are crescent.

@mixiekins 3 года назад

ok so update: it's only some that are crescent, and a lot of the samples have howell-jolly bodies floating around with them, too! I really hope there's a little series on blood, because now I'm really interested, like what mechanism caused the cells to clot in some footage whereas they hadn't clotted in other scenes. Maybe we can see bone marrow, too!

@SterlingCat03 2 года назад

@@mixiekins Actually, it depends on the genotype of the individual. If they have only one sticker cell gene, only some of their blood cells are affected, but if they have two, all of them are.

You’re not alone. Public school doesn’t teach information primarily, it teaches kids how to “school”. Children learn how to please teachers, how to respect authority, that they are always recorded and graded, etc. Many children instinctively rebel, but not generally against the material, which is usually rediscovered as adults under conditions of liberty whence it is fascinating and illuminating. -sincerely, a public school teacher.
