Peer review has been under attack lately, particularly due to the whole Arsenic Life story. These criticisms though, are not new, and new approaches have been proposed, for a long time, to address some of its weaknesses.
I just want to share with you a Nature‘s web debate, consisting of “22 articles of analyses and perspectives from leading scientists, publishers and other stakeholders“, discussing peer review and addressing questions such as “What is the best method of peer review?”, “Is it truly a value-adding process?”, “What are the ethical concerns?”, and “how can new technology be used to improve traditional models?”.
Also, be sure to follow fellow biologists Jonathan Eisen (@phylogenomics) and his brother Michael (@mbeisen) on Twitter, for more about these sort of debates, and everything related to scientific publishing.
There are far many more that I could recommend, so just get on Twitter and let your timeline guide you through the Science Twitverse.
