The world's nine oldest surviving "antique" astronomical observatories
Since the birth of man on earth, man's reverence for the heavens and his search for the mysteries of heaven and earth has rarely ceased. Astronomers and artisans have also built various observatories. Even today, one cannot help but admire the subtlety of the ancients in their grasp of the planets, constellations, and seasons.

For the first time! Injection of young cerebrospinal fluid may reverse brain aging
Normally, our brains don't get water, but there is water in it, about 150 to 270 milliliters. The water is colorless, transparent and like plasma. Also known as cerebrospinal fluid, it fills the brain and spinal cord and is produced by the choroid plexus of the lateral ventricle, the third and fourth ventricles. In order to maintain volume stability, excess cerebrospinal fluid will also be excreted by the spinal cord.
