Study: Telomeres Don’t Shorten with Age in Longest-Lived Bats

Diana Kwon | Feb 7, 2018 | 1 min read

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

Katarina Zimmer | Nov 17, 2017 | 3 min read

Shorter telomere length is widely considered a manifestation of stress in young children, but the results of a new study find it’s more complicated than that.
