> It might be reasonable to think that there's an indelible link between the heart and the body it resides in -- the processes that affect one inevitably affect the other. But a new preprint, [2]uploaded to bioRxiv and yet to be peer-reviewed, suggests that this may only be true up to a point. Take the heart out of the body and put it in a new one, and something incredible happens. The transplanted heart begins to take on the biological age of its new owner. Older hearts transplanted into younger recipients [3]appear to become biologically younger , while younger hearts placed in older bodies show signs of accelerated aging.
