Australian and Dutch researchers have uncovered a remarkable evolutionary adaptation in birds that could hold vital clues for combating avian flu and respiratory infections in humans, including ...

When it comes to studying lungs, humans take up all the air, but it turns out scientists have a lot to learn from lizards. A new study from Princeton University shows how the brown anole lizard solves ...

For the past two years, scientists, public-health officials and even a high-ranking government official or two have warned about the potential danger of a deadly worldwide outbreak, or pandemic, of ...

Breathing is such an unconscious event – except when it isn’t. Then and only then do we get a suffocating sense of how dependent we are on our efficient and expertly packed lungs to keep us both alive ...
