Now that we're on our way to in vitro meat and artificial eggs, how about some lab-synthesized toast? Okay, scientists can't grow a loaf of bread in a test tube, but they have been able to create edible starch from otherwise indigestible cellulose – that is, from wood. Though the process is currently difficult and expensive, it may one day allow us to turn wood, agricultural waste and even algae into delicious, nutritious starch. Time for pancakes, potatoes, and pasta to come fresh from the forest! Read the scientific paper here. Story via the Guardian. Image via Celebrate Forests.
