Science spat over discovery of arsenic-eating bacteria
Is this really a spat? Or is this just how these studies end up being studied in greater depth and then confirmed (or not) and clarified?
WASHINGTON (AP) — A scientific tiff went public Friday as the journal Science took the unusual step of publishing challenges to a report about a strange, arsenic-eating bacteria.
The authors of the study stood their ground, saying they still consider their interpretation of the research viable.
In the report published in Science last year, researchers led by Felisa Wolfe-Simon of NASA’s Astrobiology Institute said they discovered bacteria that can substitute arsenic for some of the phosphorous in its diet. While the discovery was made on Earth, they said it shows that life has possibilities beyond the major elements that have been considered essential.
