Aging mice’s blood got healthier by quieting a telomere damage alarm
1 month ago
Every chromosome ends in a telomere. It is a cap of DNA that keeps the end from fraying, and it wears down as you age. Every telomere headline you have seen is about making that cap longer. This study never lengthened one. The team switched off the alarm that a worn-down telomere sets off, and the mice got better anyway. If that holds up, length was never the lever.
