Mike Lemonick, Time's excellent senior writer on science, has started a blog. I can't think off the top of my head of another staff science writer at a big magazine or newspaper who has a blog (as opposed to us itinerant science scribes). So welcome to Mike. One quibble: why no comments? A journalist who doesn't let blog readers comment is...well, I won't use bad language here (but I will here). Perhaps that's the downside of life on staff--lots of lawyers hovering about.
