Scientific American partnered with grassroots organization ScienceDebate.org earlier this summer to encourage the two main presidential candidates--Barack Obama and Mitt Romney--to answer 14 questions on some of the biggest scientific and technological challenges facing the nation. Pres. Obama and Gov. Romney have now answered these Top American Science Questions, which you can read below.

Editors will grade the candidates' answers for SA's November issue, which will be available on the iPad and in print in mid-October.

In the meantime, we need your help with this project. Do you find that the candidates' answers adequately address the thrust of the questions or do they sidestep important issues? Do the answers put forth concrete solutions? Did you find any of the answers particularly helpful or surprising?

We will highlight the most thoughtful and constructive comments and consider the best, verifiable information that you give us in our own deliberations and analysis. Please make sure to register with accurate contact information so that we can email you directly for followup questions, if need be.
