Since beginning his career as an engineer for Douglas Aircraft, Frederick Sachs has been a research fellow at NIH's biophysics laboratory, and served as both an NIH physiology reviewer and NSF consultant. His most recent work, as professor of physiology and biophysics at the University of Buffalo, pinpointed a protein in tarantula venom as a potential drug candidate to treat atrial fibrillation. In a provocative Opinion, Sachs proffers that funneling more money into the NIH budget ha

How far has open access come in a decade? And where will it go in the next?

Fixing authorship In his column "Me first!" Glenn McGee proposes two changes to fix the system of scientific authorship.1 Drawing simple authorship rules is easy when a paper requires a single field of expertise and can be understood by all authors. However, many papers require that people from different fields come together, and not all authors will understand all the aspects of the paper, even if they devised part of the strategy. How can rules deal with that? Disputes aris
