Scientific American: Did new microscope discover the ancient Chinese meridian lines?

With all that’s known about human anatomy, you wouldn’t expect doctors to discover a new body part in this day and age. But now, researchers say they’ve done just that: They’ve found a network of fluid-filled spaces in tissue that hadn’t been seen before.

These fluid-filled spaces were discovered in connective tissues all over the body, including below the skin’s surface; lining the digestive tract, lungs and urinary systems; and surrounding muscles, according to a new study detailing the findings, published today (March 27) in the journal Scientific Reports.
