Johns Hopkins researchers say they have identified a new disease gene that, when mutated, appears to increase the risk in a small number of people of developing emphysema and a lung-scarring condition known as pulmonary fibrosis.

Like a car's front and back bumpers, your cell's chromosomes are capped by "telomeres" that protect this genetic material against deterioration. Still, after enough replications, a chromosome's telomeres break down and once ...
