Rosie Redfield from the College of Bc has steadfastly elevated doubts concerning the headline-getting news about arsenic-based existence last November. (If neither arsenic existence nor Rosie Redfield ring any alarms for you personally, take a look at my two pieces for Slate, in December and June.) Redfield then did something exceptional: she set to replicate the first findings, obtaining the original bacteria and seeing if they'd like to build DNA from arsenic when missing out on phosphorus.
After which she did something quite unique: she began to chronicle her encounters on her behalf blog. This is an amazing look in to the lab notebook of the practicing researcher. Today s publish is particularly intriguing:
First evidence refuting Wolfe-Simon et al. s results
Amongst other things, Redfield reviews the bacteria appear to have the ability to grow at really low amounts of phosphorus levels the original researchers stated were lacking to sustain the development they saw.
Obviously, Redfield provides extensive work left to complete. She'll have to operate this experiment to its bitter finish, write down the outcomes, submit a paper to some journal, have it past peer review, and publish it inside a peer-examined journal. But we are able to all watch her journey instantly.
