Ars Technica writes: "This week's issue of Science takes a look at work that could help bridge the gap between biomass fuel production and traditional petrochemical engineering. Modern society relies on petrochemicals not only for our primary transportation needs, but also for most of the chemicals and polymers that we use. With the increased focus on using woody and agricultural stock to create biofuels, most notably bioethanol, it is worth asking if these feedstocks can support the rest of our petrochemical needs."
