aibo, sleepy, cute

slower than a Slowpoke stuck in treacle

My literature report is coming on so slowly. I'm STILL working on the section that I'd meant to have finished by last Saturday. At this rate, I'll be taking it to New York with me, and be sitting holed up in our hotel room working on it there instead of sightseeing with my family. This is my life right now.

Getting to the British Library today has failed due to snow and lack of trains. There was a train stuck outside our house for half an hour earlier - I think the power to the lines failed. If it loses power, that's heating gone, and I can't carry a blanket as well as everything else :(

And it seems that the National Rail website is lying about train existence - I can see and hear them from here, but trains that I haven't seen or heard have been disappearing off the live update as if they've happened. But I've called the library and they're holding my books for another 3 days.

So very tired.

This is the most awesome thing in the whole world ever!

Bacteria first species observed to use arsenic-laced DNA backbone

Evolutionary geochemist Felisa Wolfe-Simon, the lead author, and her colleagues found a strain of bacterium (GFAJ-1 of the Halomonadaceae family) that can grow in a medium abundant in arsenic and lacking phosphorus. The GFAJ-1 bacterium naturally resides in the arsenic-rich waters (200 uM) of Mono Lake located in California's Eastern Sierra, and it belongs to a family of proteobacteria that is known to accumulate arsenic. It's not remarkable that GFAJ-1 survives in high concentrations of arsenic, but what is startling is that it potentially integrates arsenic into its DNA and proteins.
