Announcing the Nature Index: A global indicator of high-quality research
The Nature index tracks the affiliations of high quality scientific articles published in 68 science journals independently chosen by the scientific community as the journals scientists would most like to publish their best research in. Updated monthly, the Nature Index presents research outputs of over 7,000 parent institutions worldwide presenting a page of output statistics for each institution along with information on institutions collaborating with the institution in the publication of Index articles. Each of the approximately 60,000 articles in the Index has a dedicated article page with social and mainstream media coverage tracked by Altmetric. League tables of output of institutions can be generated on the fly on a global, regional or country basis and by broad subject area as well as by article count and fractional article count. Use Nature Index to interrogate publication patterns and to benchmark research performance and collaboration worldwide.

Nature Publishing Index Asia-Pacific
The Nature Publishing Index Asia-Pacific tracks research published in Nature journals from the Asia-Pacific region during the past 12 months, and is updated weekly. The Index provides many different options for users to delve into the data: users can analyze data by institution, country or subject, and can access historical data and graphs of historical performance. The ‘Latest research’ section contains a complete list of all the articles published in the past month with an author from the Asia-Pacific.
For many years, science in the Asia-Pacific region has been dominated by Japan. However, as seen through the lens of the Nature Publishing Index (NPI), the fastest growth in high-quality research is now coming from other countries — in particular China and Singapore. The 2013 NPI Asia-Pacific presents an analysis of the dynamic changes in the region’s scientific publishing record.

Introduction to the Index
The Nature Publishing Index ranks institutions according to the number of primary research articles they publish in Nature journals. Nature and its family of Nature-branded sister journals is world-renowned as the pre-eminent platform for publication of the very best international research, and it is fitting that this portfolio of high quality journals serve as a benchmark for research success and achievement.
There are many ways to assess the research output of institutions, and the Nature Publishing Index is just one that should be used alongside many. Users can drill down to find the abstracts of individual papers that make up the Index allowing deep analysis of where some of the best research across a broad range of fields is coming from.
However, there are caveats that must be applied in interpreting the Index. For instance, Nature journals, although covering a broad spectrum of basic research in the life sciences, physical and chemical sciences, provide relatively limited coverage of applied sciences, engineering and clinical medicine. The Index should therefore be viewed as primarily an index of high quality basic and not applied research (although there are exceptions such as the journal Nature Photonics, based in Tokyo, which covers both domains).
The corrected count is a score that takes into account the number of affiliated institutions per author and the percentage of authors per institution. It is a decimal fraction up to a maximum of one calculated for each paper for a given institution or country affiliated with the paper, by taking into account the percentage of authors of the paper from that institution or country. All authors are assumed to contribute equally to corrected count, and an author with multiple affiliations is assumed to be divided equally among those affiliations. When an author gives a "present address", "permanent address" or "current address" that affiliation is assumed to not be involved in that author's contribution to the paper and is not included in the corrected count. The rules governing the calculation of corrected counts with respect to the way affiliations are presented are expanded regularly to account for new scenarios and any such additions to the rules are added to the footnotes to the tables.
The number of articles reflects the total number of articles with which a particular institution or country is affiliated according to the stated affiliations of authors in each publication. Institutions and countries are counted once per article. Advance online publications are not included until assigned issue and page numbers. Articles consist of Research Articles, Letters and Brief Communications published in Nature journals.
Nature Publishing Index - 2013 Global Top 200
Simultaneous with release of the 2013 Asia-Pacific rankings of the Nature Publishing Index, Nature Publishing Group (NPG) has updated the website that ranks the top two hundred institutions in the world according to their output of papers in Nature primary research journals. The index, called the Nature Publishing Index Global Top 200, gives an indication of where some of the best research in the world is being carried out across the broad range of fields encompassed by NPG’s 17 Nature-branded primary research titles in life sciences, physics, chemistry, materials, nanotechnology, photonics and geoscience.
Institutions in the United States and Europe dominate with US institutions occupying seventy nine of the top one hundred positions and Harvard University the number one slot. But Asia has quite strong representation with seventeen slots. The Chinese Academy of Sciences (CAS), which is number one in the Asia-Pacific rankings, is number six in the top one hundred followed by The University of Tokyo at 8, Kyoto University at 27, RIKEN at 31, Osaka University at 41, National University of Singapore (NUS) at 46, Tohoku University at 47, The University of Melbourne at 54, University of Science and Technology of China at 57, Tsinghua University at 64, Australian National University at 72, Nanyang Technological University (NTU) at 73, Korea Advanced Institute of Science and Technology (KAIST) at 77, Peking University at 81, BGI at 87, Nagoya University at 88 and The University of Queensland (UQ) at 91. With the quantity and quality of research produced by scientists in the Asia-Pacific increasing year-on-year it is reasonable to expect that more institutions from the region will feature in the top echelons of the global Nature Publishing Index before long.
Nature Publishing Index Global 2012
We are delighted to present the first global overview of high quality research output from the world’s many countries and institutions based on the Nature Publishing Index (NPI), which tracks the number and affiliations of primary research articles published in 18 Nature-branded journals.
Created in 2009 to focus on the Asia-Pacific region, the NPI now covers the entire world. Using the Index, we are able to track output by institution and country. The NPI is a unique resource that spans all types of research institutions — not only universities but government research institutes and private sector companies.
Nature Publishing Index China
The Nature Publishing Index 2012 China adds to the growing body of evidence that China is fast becoming a global leader in scientific publishing and scientific research. The number of papers from Chinese institutions in the NPI grew by 35% from to 2011 to 2012. The NPI measures the output of research articles from nations and institutes in terms of publications in the 18 Nature-branded primary research journals in 2012, with 2008-2011 data included for comparison.
