A Stanford University–led study published December 2 in PNAS Nexus finds that gas and propane stoves expose millions of Americans to substantial indoor nitrogen dioxide levels, in many cases matching or exceeding outdoor pollution. According to the research, replacing gas with electric stoves could cut average nitrogen dioxide exposure nationwide by more than one quarter, with particularly large benefits for people in smaller homes, renters, and rural households.
Engineers at the University of British Columbia’s Okanagan campus have designed a new airflow device that traps exhaled aerosols almost immediately, sharply reducing exposure to airborne pathogens in simulations. Early results suggest the system can substantially outperform conventional ventilation approaches in shared indoor spaces.

WIRED has refreshed its recommendations for humidifiers, highlighting models that ease maintenance and improve indoor air quality amid dry winters. The guide emphasizes devices suitable for homes, travel, and sleep, based on testing in a New York City apartment. Ideal indoor humidity is noted as 30 to 50 percent to reduce illness spread and discomfort.
