MR.KNOW-IT-ALL YOUNG BLOOD,TECH SWAG

摘要

So yeah, I went and read about this too. I read that for years scientists have been taking an old mouse and a young mouse, putting them next to each other, and stitching their circulatory systems together, just like jump-starting a car. Then they let the blood of one mouse circulate through the other-a process called parabiosis. And introducing the young mouse's blood-or even just introducing one particular protein found in the blood, called GDF11-to an old mouse does all sorts of wonderful stuff: It allows the old mouse to run longer on a treadmill. It changes the old mouse's brain in ways that suggests its memory has been improved. I read that it even rejuvenates a crusty old-mouse heart. Like, voila! The heart isn't crusty anymore.
