These people are still finding new parts of your body in the 21st century yet they want to tell you millions of years of evolutionary history they've never seen...I will praise thee; for I am fearfully and wonderfully made: Psalm 139:14
"When you woke up this morning, you did so with an entirely new body
part—at least in the eyes of science. You can’t see it or touch it, but
it will play a crucial role in understanding neurological diseases and
immunity.
Researchers at University of Virginia’s School of Medicine recently
discovered a long-hidden system of vessels they've coined the “central
nervous system lymphatic vessels,” which drain lymphatic fluid from the
brain to the surrounding lymph nodes.
The discovery, published in Nature, has shaken up the scientific community.
The study was headed by Antoine Louveau,...The team detected the vessels after Louveau developed a method for mounting a mouse’s meninges (membranes covering the brain) on a slide without ruining the delicate tissue. When he saw vessel-like patterns in the distribution of immune cells, he tested for lymphatic vessels—and the results surprised everyone. They were also able to find the vessels in human brain samples.
This find is the neuroimmunological version of stumbling across a
unicorn. Not only had the system gone undiscovered until now, but
textbooks argued against its very existence. As a result,
neuroimmunologists have struggled to understand the mechanisms of brain
drainage and inflammation." MentalFloss
