Follow arsenic life science "live"

Professor Rosie Redfield’s (UBC, Vancouver, Canada) on-line criticism of Felicia Wolfe-Simon’s proposal that a particular species of bacteria utilising arsenic in place of phosphate in it’s DNA backbone featured in early criticism of this work.

Having obtained samples of the bacteria, Prof. Redfield is live blogging her research on GFAJ-1. The articles are a little geeky–it is research, after all–but I’d encourage my non-scientist readers to try their hand at following the story as it evolves, as it gives you a feel for a research project.*

So far there is:

• Just in case I do decide to test the #arseniclife …
• Starting to work with GFAJ-1!
• They’re here!
• Counting the GFAJ-1 cells
• Vitamins are for wusses (#arseniclife)

(As you can guess from the hashtags in the titles she announces (some of the) new blog posts on her twitter account using the #arseniclife hashtag.)

And some backgrounders:

• How to test the arsenic-DNA claims
• How might a bacterium evolve to use arsenic in pla…
• Working safely with arsenic (what I’d need to know…
• Guest post about #arseniclife

For those wanting the back story, are her earlier posts responding to the original paper; I’ve also briefly pointed at the published criticisms. There are the latter two from many:

• Arseniclife: The formal critiques and the authors’…
• Wolfe-Simon et al.’s responses to my comments

Footnotes

If I wasn’t over my head in work and I’d at least tempt myself into pitching in with some analysis of their DNA sequence data (from other work in their lab, unrelated to the arsenic life study, see also the earlier postson this [among others]). It’d be fun. Looking at protein-DNA interactions was my first love. Erm, research-wise, that is!

* Less funding and teaching. Endless grant applications are part of the deal and, for most, so is teaching (and the inevitable marking that comes with that) and of course lab and departmental administration. But you’ll still get to see part of the research part of things. Also, few research projects get this amount of attention!
