Names such as Leonardo da Vinci and Dmitri Mendeléiev are icons of great advances in knowledge. But science is not about just one person. 50 years ago, mankind reaching the Moon was made possible by a large multidisciplinary team and that is, in fact, the current trend. Nowadays, the boom in new digital technologies, open science and the larger role civil society is playing in decision-making is encouraging citizen involvement in certain scientific projects. This is citizen science in which non-specialists actively participate in some of the research processes.
