Every two months, Essential Science IndicatorsSM from Thomson Reuters lists a new crop of what it calls hot papers in science. Hot papers are selected by virtue of being cited among the top one-tenth of one percent (0.1%) in a current bimonthly period. Papers are selected in each of 22 fields of science and must be published within the last two years. Because the hot papers are updated every two months, new papers are added with every update, and ScienceWatch.com tracks these new additions.

Here, ScienceWatch.com highlights selected examples of these hot reports, allowing authors to provide background and context, along with their thoughts on why the paper is attracting a notable level of attention. Since new hot papers are very recent scientific contributions that are receiving recognition during a current period, they may signal important new trends in research and serve as leading indicators of scientific advancement. Full information, including bimonthly citation histories, for these papers can be found in Essential Science Indicators. See also, Understanding Core Data; Hot Papers Methodology.
