For this the chosen corpus was constituted from the texts of the Superinteressante magazine, and the main concepts used to support this work were the dialogical theory, memories of the future, the incompleteness and the valuation of aesthetic Bakhtin. We will also use Leon (1999), who shows us the ways and history of scientific discourse. Thus we have as hypotheses of how this discourse is constructed, how it is valued and how it also serves to entertain and inform. We also use old speeches about the apocalypse, as the Holy Bible, the Mayan prophecies and the prophecies of Nostradamus to turn the discourse of the magazine historical discourses, seeking thereby modeling common to apocalyptic discourse. Thus, it seeks to relate all these concepts with the main problem: how language mediates to change the perception of science and society. / Este trabalho busca indícios de como os discursos da ciência são transmitidos para a sociedade e, inclusive como nesse jogo também encontramos embates ideológicos entre essas duas forças discursivas. Para isso o corpus escolhido foi constituído a partir das textualizações da revista Superinteressante, e os principais conceitos utilizados para embasar este trabalho foram a teoria dialógica, as memórias de futuro, o inacabamento e a valoração do estético de Bakhtin. Também utilizaremos Leon (1999), que nos mostra os caminhos e a história dos discursos de divulgação científica. Desta maneira temos como hipóteses de como esse discurso é construído, como ele é valorado e como ele também serve para entreter, além de informar. Utilizaremos também discursos antigos sobre o apocalipse, como a Bíblia Sagrada, as profecias Maias e as profecias de Nostradamus para ligar os discursos da revista com os discursos históricos, buscando assim, modelações comuns aos discursos apocalípticos. Desta forma, busca-se relacionar todos esses conceitos com o problema principal: como a língua serve de mediação para mudar a percepção de ciência e de sociedade.

Diploma thesis "Principles of popularization of scientific knowledge on the Czech and American news servers" evaluates and compares news published during three month period in scientific sections of news servers in the Czech Republic and the United States of America. The thesis follows room provided for scientific topics, the audiovisual features and theme agenda on NYTimes.com, USAToday.com, iDnes.cz and Novinky.cz. The results are accomplished through the quantitative content analysis which is supplemented by the qualitative semiotic analysis. The semiotic analysis determins compositional and narrative structures and the language features in the articles. It is very important to be concerned about the scientific journalism, as science is important in people's lives and, furthermore, it is the public who helps to support scientific efforts financially. Thus, scientists should be concerned about and aware of science communication in media.
