Unsurprisingly, microRNAs dominate the list of highest cited papers, and the area is witnessing rapid growth. The number of papers in other fields, such as proteomics, nanotech and RNA interference, also continues to expand; 80% of the publications specifically reporting cancer stem cells were published in the past two years. China and India continue to increase their output of biotech papers; France fell behind Spain and Italy; Switzerland entered the top 15 for the first time.
