May 28, 2010 at 4:39 PM ETWe're finishing up the first week for the new blog design, and although there may be a few tricks I still need to learn, the process so far has been fairly painless. One of the new features is the ability to publish "clippings" from other sources on the Web. This is a nice, easy way to supplement your daily dose of science, but it doesn't really give you a chance to comment on the links or talk more generally about what's on your mind. So I'll continue to offer a weekend roundup of Web links, just like this one. Feel free to leave comments about other reports you've seen on the Web, or weigh in with your own cosmic commentary. Regular postings will resume on Tuesday.
