Exposure to 'third-hand smoke' — that is, the chemicals left behind on household surfaces after smoke has dissipated — increases the severity of asthma symptoms in mice. Stanford researchers are working to learn how this happens, and whether it might be possible to protect people with asthma from this exposure.

What makes breathing possible is a thin coating of a soaplike film, or surfactant, that lowers the tension of the lung’s inner surface. Premature babies and adults with lung injuries are short on surfactant, and replacing it has been prohibitively pricey. That may be about to change.
