But a new study suggests that violence in childhood may leave a genetic mark as well. Researchers have found that children who are physically abused and bullied tend to have shorter telomeres—structures at the tips of chromosomes whose shrinkage has been linked to aging and disease. Telomeres prevent DNA strands from unravelling, much like the plastic aglets on a shoelace. When cells divide, these structures grow shorter, limiting the number of times...
