"Revitalizing Aging: Young Mice's Blood Holds the Key to Longevity"
Scientists have discovered that connecting the blood vessels of old mice to young mice can extend the lifespan of the older animals by 6 to 9 percent, equivalent to six extra years for humans. While this study does not provide an anti-aging treatment for humans, it suggests that compounds in the blood of young mice may promote longevity. Parabiosis, the joining of animals together, has a long history in scientific research and has previously shown rejuvenating effects on muscles and brains in old mice while accelerating aging in younger mice.
