摘要

In what sounds like a scene from a science fiction movie, researchers in 2005 stitched together old and young mice so they shared a circulatory system. Youthful blood seemingly rejuvenated many tissues of the elderly rodents, boosting their cognitive and physical performance. Now, scientists are examining whether certain molecules in young blood could help treat age-related diseases, according to an article in Chemical & Engineering News (C&EN).
