US scientists have created a tiny device that simulates a working human lung and could reduce the need for animal drug testing. The “lung-on-a-chip” contains hollow channels lined with living human cells that mimic the interface between the air sacks in the lung and the blood vessels beneath, allowing scientists to study the body’s response to lung infections and diseases.
