Scientists Just Discovered a New Human Sense of Touch
A new study reveals a previously undiscovered way that we can feel light touches: directly through our hair follicles.
Before now, it was thought that only nerve endings in the skin and around the hair follicles could transmit the sensation.

“The test measures the level of anti-Mullerian hormone (#AMH) in the blood and is known clinically as an AMH test.
AMH is produced by follicles in the ovaries (little fluid-filled sacs that contain immature eggs) and helps follicles and eggs grow during the menstrual cycle. Because the number of #follicles in the #ovaries drops with increasing age, the level of AMH also falls.”

Do you think about the mites that live in your #face #follicles and come out at #night while you #sleep? Maybe you should!
They’ve #evolved a tiny #genome.
Each leg segment is powered by only one #muscle cell.
They follow your sleep cycles by responding to your #melatonin.
Lowest number of cells of any #arthropod.
If you find this intriguingly #weird, this paper is for you!
