On Our Radar: Visualizing Your City's Emissions Relying on public data mining, traffic simulations and building-by-building energy consumption, researchers develop software capable of estimating greenhouse gas emissions across entire urban landscapes. Phys.org An ethics watchdog group files a complaint with the Federal Election Commission over an Ohio coal company's alleged requirement that employees donate to Mitt Romney's presidential campaign.
