Polish university students are using Wikipedia and "crib sheet" websites as the main source for their master's thesis, a new survey reveals.

Strong demand for ghost-written academic papers in the lead-up to university graduation and revelations that people pay to have scholarly articles published are worrying critics who fear the billion-yen industry is making it harder than ever to evaluate graduates' abilities.

An investigation published by Nature, reveals that a scientific plagiarism has course among researchers too. Two researchers from South-western Medical Centre of the University of Texas, Mounir Errami and Harold Garner, auscultated an American medical documentation base, Medline, where summaries of 17 million articles published in more than 5,000 reviews from some 80 countries are indexed. They screened it through an engine search, eTBLAST, which is able to locate the "similarities". While focusing on the most quoted 7 million articles, they located a little more than 70,000 cases of "high resemblance". That which, taking into account the limits of the software, makes them estimate the number of plagiarisms at more than 200,000, out of the 17 million referred articles.

The ministry of Higher education and research entrusted to the national Centre of scientific research (CNRS) a mission on scientific integrity. Scientific fraud is varied: biased manufacturing or forgery of results, biased interpretation or selection of data, alteration of curves or images, plagiarism, theft of ideas, financial profit-sharing's ... The increasing pressure which practices on the researchers (among which the career and the credits depend strictly on the quantity of articles and on produced results) tend to multiply the fraudulent practices.
