AI Thread Summary
Centrioles exist in pairs because they serve as attachment points for spindle fibers, which are essential for separating chromosomes during cell division. Each pair of centrioles provides a separate point of attachment for the spindle fibers, ensuring that each daughter cell receives a complete set of duplicated chromosomes during mitosis. This pairing is crucial for the accurate distribution of genetic material.

I notice that centrioles always exist in pair. May I know why?

Simplest answer - centrioles are the points of attachment of the fibers that pull apart the pairs of chromosomes - these are spindle fibers. Centrioles are in pairs because two separate points of attachment are required -> one for each daughter cell. Each daughter gets a copy of the duplicated chromosomes during mitosis.

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...
