biofuels have fallen from grace with alarming speed. What looked like the future of transport a year ago is now seen as a threat to food provision and the environment alike. Today's issue of Current Biology contains a few news features on these problems, and I've written the one on the impact of biofuels on African countries. Apologies for the title which I didn't choose or approve

PS: Further bad news on biofuels is in the Guardian today.
