Physicists suggest how evolution has shaped our lungs through successive optimizations of physical parameters such as conservation of energy and speed of delivery. Our respiratory system consists of a ...

In 1985, we hypothesized that a living vital organ could be rationally designed and built for human therapy from cells and degradable polymer scaffolding. This was based on only two pieces of previous ...

Previously linked to the severity of asthma and chronic obstructive pulmonary disease in humans, vitamin D deficiency has now been shown to alter lung structure and function in young mice. The new ...

University of Delaware Assistant Professor Catherine Fromen and current graduate student Dominic Hoffman work with an adaptable lung model that can replicate realistic breathing maneuvers and offer ...

Take a deep breath in. Slowly let it out. You have just participated in one of the most profound evolutionary revolutions on Earth--breathing air on land. It's unclear how the first vertebrates ...

Very severe chronic obstructive pulmonary disease causes cor pulmonale with elevated pulmonary vascular resistance and secondary reductions in left ventricular filling, stroke volume, and cardiac ...

Respiratory diseases are a challenging problem to treat. Inhalable medicines are a promising solution that depends on the ability to deliver tiny particles known as aerosols to the correct location in ...
