They have struck again, and removing all their odes about "spam, spam, spam, lovely spam", or rather their pages upon pages of link adverts for pr0n, pi11z and war3z, took me half an hour of my maybe-generally-not-too-precious-but-still-too-precious-for-this-garbage time. I have hence reenabled comment moderation, which I disabled after no comment spam had appeared for several months in the (apparently mistaken) belief that Blogger had come up with a working spam filter. Please accept my apologies for any inconvenience this measure may cause.
On the physics front, everything is now abuzz with news that the Chandra X-ray observatory has made the most direct observation of dark matter so far. Read more about it from Rob Knop, Steinn Sigurðsson, Chad Orzel, Clifford Johnson and Sean Carroll, or read the original NASA press release. The BBC is also reporting.
