It is widely accepted that science is universal by nature. However, to make science universal, access to research findings is imperative. The open access model of publication of academic articles was established and consolidated during the last two decades. However, most of the open access journals apply article-processing charges (APCs), which can cost more than USD 10,000.00. In regions where support for research is scarce, these funds are usually not available. Similar problems occur in countries with weak economies and, consequently, unfavorable currency conversion rates. This situation reveals a barrier to the alleged universality of science and the access to research findings. In this manuscript, the barriers faced by authors and institutions from low-to-middle income regions to cover APCs and make their science freely available are discussed and illustrated with recent numbers.
