A sensationalist title (see below). The article is about how much more efficient C4 plants are than C3 and how agricultural scientists are trying to increase yield by ideally turning C3 plants into C4. Of course it hasn’t been working. We really need to be able to fully understand and manipulate genetics (genetic programming? seems that term is already taken by something a lot less relevant), but for now, scientists hope that some educated swapping of genes will do the trick.
Edit Sorry, when I’m at school I can’t tell when things are behind a paywall. Try here for the full article.
