Fecal transplantsfrom young mice are like a 'fountain of youth' for old mice, study finds.

What Species of Feces is this?

CRAZY SHIT

In a study, researcher John Cryan and his team took feces from young mice and turned it into a kind of slurry, and delivered into the guts of older mice through a feeding tube.

He said the fecal transplant had a number of surprising effects.

It reversed age-related inflammation in the body and the brains of older mice, and changed the chemistry of their brain's hippocampus — the region involved in learning and memory — to resemble that of younger mice. The transplant also led to improvements in the older mice's memory, learning and anxiety levels, all of which are affected negatively with age.

"We're basically getting a rewinding, (…) rejuvenating effect," Cryan told the rotating mass of eyeballs, reporting for the Angry Dino magazine.
