In this article for Discover Magazine, I dig my teeth into a new set of experiments that seems almost supernatural: Injecting aging mice with blood from younger mice can reverse the aging process in their brains. Sounds like something straight out of a horror movie, doesn’t it? But its real, and it’s scientifically proven to work. Join me and find out how.
After the parabiont mouse pairs had spent five weeks sharing blood, the experimenters examined the genes in each mouse’s hippocampus – a brain structure crucial for learning and memory. They found that older mice which had gotten young blood displayed altered gene activity and more flexible signaling pathways in their hippocampus. Though the older animals’ brains didn’t transform all the way back into their younger selves, the flexibility of their connections was still well above the baseline of other mice their age.
