A fundamental part of the educational project is that concerning the dissemination of science to the general public. The INCTC, with support from the Blood Center of Ribeirão Preto, has participated in an important way of dissemination events such as National Week of Science and Technology and the meetings of the SBPC. Recently, the Blood Center purchased an inflatable dome for projection at 180 degrees with the purpose to disseminate science in the cities of the region. The original material, purchased with the equipment, is intended for the study of astronomy (planetarium) that will be adapted for the study of biology and hence the new name "celularium". The first movie available, produced in Ribeirão Preto, allows a trip in 180 degrees, in the inner of an animal cell. During the National Week of Science and Technology, 2010, we held an exhibition called "Celularium: a viagem pela célula" (Celularium: a trip through the cell) in a shopping mall of Ribeirão Preto when the equipment was presented to the visitors. The dissemination of knowledge is done through the pages of the Blood Center, House of Science, INCTC and LaNCE on the Internet. At INCTC website it is possible to find all information about the program (research projects, participating researchers, students, publications, reports, etc.), and a tool for the interaction among participating researchers. This intense activity involving the transfer of knowledge to broad sectors of society (teachers, students, patients, managers and general public) has professionals entirely dedicated to this function (journalists, programmers, educators, translators, video producers and managers), besides an adequate infrastructure (television studio, video-conferencing equipment, graphic-art stations, Internet servers of high-performance, etc.). The Blood Center TV, for example, is a tool that broadcasts via Internet, lectures and lessons that can be accessed from anywhere with access to broadband Internet.
