The infusions of youthful blood led the older animals to live 6 to 9 percent longer, the study found, roughly equivalent to six extra years for an average human. While the study does not point to an anti-aging treatment for people, it does hint that the blood of young mice contains compounds that promote longevity, the researchers said. Joining animals together, known as parabiosis, has a long history in science. In the 19th century, French scientists connected the blood vessels of two rats. To prove that the rats shared a circulatory system, they injected belladonna, a compound from the deadly nightshade plant, into one of the animals. The pupils of both rats dilated.

The hope is still alive and even growing today—never mind that it’s still not possible. When Aaron Drake flew from Arizona to the Yinfeng Biological Group in China’s eastern Jinan province in 2016, he was whisked into a state-of-the-art biotech hub. More than 1,000 staffers—including an army of PhDs and MDs—were working on things like studies of the stem cells in umbilical cord blood. The center specialized in research on human cells, from gene testing to tailored cancer treatments.  But it also had other plans: cylindrical stainless-steel tanks would eventually contain corpses suspended in liquid nitrogen. The tanks weren’t installed yet, but Yinfeng hoped Drake would help with that while it invested some $7 million to get the new project off the ground. As its high-profile new hire, he was there to guide China’s first forays into cryonics, or freezing corpses for reanimation. Continued here
