I would be helpful to supply a link to the research from 3 years ago that you are mentioning.

https://en.wikipedia.org/wiki/Meningeal_lymphatic_vessels > While it was initially believed that both the brain and meninges were devoid of lymphatic vasculature, a recent study by Antoine Louveau and Jonathan Kipnis at the University of Virginia, submitted in October 2014, and another confirming the discovery, by Aleksanteri Aspelund and Kari Alitalo at the University of Helsinki submitted in December 2014, identifi…

The "they're really close to the blood vessels; you could easily miss them" answers don't make sense. Surely any time you do brain surgery in the area beside those blood vessels, you'd be studying the area minutely?

Anatomy textbooks aren't anything like real life. They're all colourful, clearly distinguished and clearly labelled, yet any autopsy will reveal a mess of reddish brown that tangles and squishes together. Also remember that human bodies aren't constructed, they're grown, so the idealised version of the textbook isn't what you end up seeing when you cut something open, and what you see when you do that changes each ti…

> the team discovered lymphatic vessels in the dura, the leathery outer coating of the brain Can someone explain why these vessels were never discovered during autopsies until now? Are they too thin, or transparent, or thought to have been something else, or the tubes become squished after death and therefore difficult to separate from other tissue, or what?

I wonder the same thing. Not to be snarky, but is there something faulty about medics or human biologists?! Why do I have a feeling that if we deployed computer scientists at medical research we would get a better result? I can accept that at the lower level things get fiendishly complex, but surely at a macro level like this it's just a case of diligent analysis?

Most professionals in the field of medicine were educated towards an elitist and dogmatic mindset. When I talk with a physician about the human body I always get the impression they really believe the body works as described in the books - exactly like that. Most of them didn't seem to have noticed or learned that what we know about medicine is just theory approximating reality and all of those theories had to be upd…

Medical doctors are not Ph.D.'s. They are technicians, more akin to an auto mechanic than a scientist.
