While researching his book, Breath, James Nestor participated in a study in which his nose was completely plugged for 10 days, forcing him to breathe solely through his mouth. "I felt awful," he says.

A 3-D printer is being credited with helping to save an Ohio baby's life, after doctors "printed" a tube to support a weak airway that caused him to stop breathing. The innovative procedure has allowed Kaiba Gionfriddo, of Youngstown, Ohio, to stay off a ventilator for more than a year.
