Some good stuff from "Discover" magazine
I got a subscription from my folks as a gift. Some fascinating stuff in there.
Latest issue has an article on a process that can cook almost anything organic into oil. With a net energy gain. Another alternative that may come into its own when supplies start running low and the prices go up.
Also in this issue: a great and detailed article on Mars Express, and an article showing that ancient Americans may not have been as peaceful as they are often depicted.
