I must admit, I am a bit surprised how much news is made out of an astronaut losing a screw and bolt. Just imagine you are in the middle of the ocean wearing a few pairs of winter gloves and trying to tighten bolts. I bet most of us would lose more than one. I'd be lucky to retain any.
My October issue of Scientific American arrived today, and the cover story is on supernovae (exploding stars). I'm looking forward to reading that. Scientific American is, in my opinion, one of the best science magazines available, so you may want to give it a look. However, it does run a bit on the dense side, so there's no need to be ashamed if you can't follow it. I often have to give up on the biology articles, as I get lost after the first page or so.
Sorry to be a bit scatterbrained today, but I'm helping some collaborators get started on a telescope run, and I am short on sleep to boot.
