This is really a placeholder post to tell people that:
1) This is still Oliver Morton's blog, but is currently being used very rarely and fitfully. It is still in principle devoted to matters martian, but for the time being I'm not updating. The set of posts on methane on Mars can be found here, and observations on the life and death of Beagle 2 can be found here. The big wodge of stuff on synthetic biology from May 2006 is here because of a snafu that stopped me blogging live to the Nature Newsblog over the relevant weekend. It is of little or no planetary science value, though interesting in other ways.
2) If you're a friend, associate or indeed enemy who has lost track of me, perhaps due to the interruption of my abq email address, you can reach me via gmail as oemorton, or at nature.com as o.morton.
