Arguments for open science

Some recent controversies around scientific publications illustrate the potential benefits of open science.
Open access publication of research reports and data allow for more rigorous peer review
An article published by a team of NASA astrobiologists in 2010 in Science reported a new bacterium known as GFAJ-1 that was purported to metabolize arsenic (unlike any previously known species of lifeform). This finding, along with NASA's claim that the paper "will impact the search for evidence of extraterrestrial life", was roundly criticized within the scientific community. Much of the scientific commentary and critique around this issue took place in public forums, most notably on Twitter, where hundreds of scientists and non-scientists created a hashtag community around the hashtag #arseniclife. University of British Columbia astrobiologist Rosie Redfield, one of the most vocal critics of the NASA team's research, also submitted a draft of a research report of a study that she and colleagues conducted which contradicted the NASA team's findings in arXiv, an open research repository, and called for peer review of both their research and the NASA team's original paper on her lab's research blog
