Can an enzyme save the planet? It’s highly unlikely, but kind of fun to think about. Scientists at Emory University School of Medicine discovered a “mutant enzyme” that, at least in theory, has interesting implications for global warming.

We all know plants take in carbon dioxide from the atmosphere for photosynthesis. Some experiments have shown that the more CO2 there is in the atmosphere, the more a plant will grow. But many people think there’s a limit, that plants won’t simply continue to take in more CO2 the more we send it into the atmosphere thorugh fossil fuel emissions and burning down rainforests.
