The goal of this activity, entitled “How does the scientific method work? Let’s do biomedical research!”, is to stimulate the creativity and thinking in students between the ages of 10 and 12, and to contribute to their educational activities. The project is part of the PCB’s “Science and Society” outreach programme, which aims to help improve the scientific culture of society in general, to promote research, and foster vocations in this field.

During the activity – which lasts from 10 to 12.30 in the mornings – students attend a theatre workshop in which two crazy scientists complete experiments using the scientific method, while explaining the function of cells, DNA...

Unless you are a molecular biologist, you may not have heard the term ubiquitin. Given its essential role in the cell, however, it is likely that its protagonism and popularity will increase. One of the processes in which ubiquitin plays a relevant role is in the degradation of proteins. In the cell, the generation of proteins is just as important as their destruction, as well as the maintenance of a correct balance between both processes.

Proteins become candidates for degradation when they are defective, when they have completed their function and are no longer necessary, or when they belong to pathogenic organisms. Ubiquitin attaches itself to these proteins as if it were an...

What would motivate anyone to wake up early on a lazy springtime weekend morning, get dressed, and head to town? Research, of course! Fifty would-be scientists made their way to the Caixa Catalunya Cultural Centre in the "Pedrera" building in Barcelona on Saturday, March 3 for a day filled with science and fun. The occasion was Fes Recerca!, a series of hands-on science workshops aimed at the general public. The events, organized by the Parc Cientific de Barcelona over four weekends in February and March, provide an opportunity for amateur science buffs to experience what it is like to do research and learn about science...
