A new study finds that exposure to a widespread outdoor fungus can increase cell damage (oxidative stress) in the airways. This spike weakens the airways' barrier defense system that, when functioning normally, removes infection- ...

Human lungs, like all organs, begin their existence as clumps of undifferentiated stem cells. But in a matter of months, the cells get organized. They gather together, branch and bud, some forming airways and others alveoli, ...
