Study: Telomeres Don’t Shorten with Age in Longest-Lived Bats
Diana Kwon | Feb 7, 2018
Researchers find that while bats in the Myotis genus don’t produce telomerase, the enzyme that lengthens telomeres, they possess 21 telomere maintenance–related genes.
Telomere Length and Childhood Stress Don’t Always Correlate
