The bot channels smoke into a "lung on a chip," a small device with microfluidic channels lined by human lung cells. This setup enables researchers to realistically replicate the action of taking regular pulls from a cigarette, and to watch the effects on the lung cells. Researchers can't achieve the same realism with cells cultured in a petri dish or with lab mice -- which, interestingly, are "obligate nasal breathers" that typically take in air through their noses. The invention was announced yesterday by the Wyss Institute for Biologically Inspired Engineering.
