Researchers at Harvard's Wyss Institute for Biologically Inspired Engineering have created a device that mimics a living, breathing human lung on a microchip. The device, about the size of a rubber eraser, acts much like a lung in a human body and is made using human lung and blood vessel cells.

Because the lung device is translucent, it provides a window into the inner-workings of the human lung without having to invade a living body. It has the potential to be a valuable tool for testing the effects of environmental toxins, absorption of aerosolized therapeutics and the safety and efficacy of new drugs. Such a tool may help accelerate pharmaceutical development by reducing the reliance on current models, in which testing a single substance can cost more than $2 million.
