Study challenges existence of arsenic-based life, Nature

"A group of scientists, led by microbiologist Rosie Redfield at the University of British Columbia in Vancouver, Canada, have posted data on Redfield's blog that, she says, present a "clear refutation" of key findings from the paper. Redfield and her collaborators hope to submit their work to Science by the end of the month. She says that if Science refuses to publish the work because it has been discussed on blogs, it will become an important test case for open science."
