Rough Drafts

The molecules making up microtubules, the protein filaments that form the internal “scaffolding” of your body’s cells, are replaced every 10 minutes. Actin filaments in the dendrites of your neurons are recycled even quicker: every 40 seconds. In fact, the entire brain’s composition turns over every

I have to admit I’m insanely jealous: The multitalented Xeni Jardin will be flying on one of Zero-G’s first commercial zero-gravity air flights, 32,000 feet up. NASA has used parabolic flight trajectories to train astronauts in weightlessness for years. Now, Zero-G will begin selling these flights —

Good advice on how to be creative: “If I was just starting out writing, say, a novel or a screenplay, or maybe starting up a new software company, I wouldn’t try to quit my job for a year and make this big, dramatic heroic-quest thing about it. I would do something far simpler: I would […]

Excuse me, but isn’t our whole country supposed to be a free speech zone??

Law student Thad Anderson has collected a bunch of government documents and made them available via P2P networks such as KaZaA and SoulSeek, through his Download for Democracy project.
