Breathtaking Breakthrough: Lung-on-a-Chip Defends Itself

In a stunning leap forward for biomedical engineering, Georgia Tech and Vanderbilt researchers have developed the first lung-on-a-chip with a functioning immune system — a miniature, living model that mimics how real lungs breathe, fight disease, and heal. This innovation allows scientists to observe immune responses in real time, potentially revolutionizing how we study respiratory illnesses and test treatments. The chip, soft and pliable like a gummy bear, could pave the way for more accurate disease models and reduce reliance on animal testing.
