Researchers at the Lawrence Berkeley National Laboratory are studying how the seemingly innocuous things we do in our homes and offices can have big impacts on our health. One of those things is cooking, because the way we cook can affect the air we breathe. Scientists are trying to figure out how to make houses safer, but to do that, they need to understand how people use houses — what we cook in them and how we cook it. You can help by taking this quick, anonymous survey.
