Two studies examining the effects of parents’ ages on their offsprings’ telomere lengths come to opposite conclusions.  

The findings contradict what has been observed in humans.  

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.

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.  

An accumulation of stressful events in childhood is associated with shorter telomeres as a person ages, researchers report. 

Endurance exercise and metabolism are linked to transcriptional activation of human telomeres, researchers propose.

A biotech company reports that an experimental treatment elongated its CEO’s telomeres. 

What researchers are learning as they sequence, map, and decode species’ genomes

Two mutations in a gene involved in telomere extension reverse the gene’s epigenetic silencing.

Researchers identify a novel protein that helps maintain the length of chromosome-capping telomeres.
