AI Thread Summary
The discussion centers on the classification of chromosomes and cells during spermatogenesis. It clarifies that despite having double-structured chromosomes (consisting of chromatids), cells like secondary spermatocytes are still considered haploid because they contain one copy of each chromosome. The maturity of cells, such as spermatids, does not affect their haploid status; they are classified as haploid regardless of their developmental stage. The term "double structured" refers to the presence of chromatids, which is a common feature during meiosis and mitosis, but can also be observed in cells undergoing spermatogenesis.

Hello everyone,

Ok I know it has 23 chromosomes. But they are double structured chromosomes, so can you still call them haploid. Also spermatids, can you call them haploid cells. You can't right because they haven't matured.

What do you mean by "double structured"? Whether or not cells have matured doesn't matter, if they have 1 copy of each chromosome that makes them haploid, per definition.

Daugher nuclei, here is a secondary spermatocyte, if you consider this as spermatogenesis. They are double structured chromosmes (consisting of chromatids). I know every chromosme has chromatids when they undergo meiosis and mitosis, but these cells have them even without undergoing it. Well they are undergoing but you see what I mean. I'm not saying you are wrong.

Thread 'New Alzheimer's Treatment Clears Plaques From Brains of Mice Within Hours'

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
