Are gas stoves really dangerous? What we know about the science

New studies show just how harmful to health they can be, but there are good alternatives to the open flame

Gas stoves are a hot topic. A new study linked them to one in eight childhood asthma cases, the US Consumer Product Safety Commission said it would look into banning them, and Republicans expressed anger at the mere suggestion.

At the same time, federal and state policies are aiming to give gas stoves' main competition - regular electric stoves and the ballyhooed induction stove - a boost.
