Air pollution is one of the leading causes of lung cancer and respiratory diseases, responsible for one in eight global deaths, according to the World Health Organisation.However, researchers will soon be able to develop new treatments for such diseases with a life-sized, artificial human lung created at the Technion-Israel Institute of Technology in Haifa, Israel. It is the first diagnostic tool for understanding in real time how tiny particles move and behave in the deepest part of the human lungs, the alveolar tissue.
