The Spanish Biophysical Society (SBE (http://www.sbe.es/) has promoted a day to promote biophysics, which was held on 25 March at the Burjassot-Paterna Campus of the University of Valencia as part of the Biophysics Week (https://www.biophysics.org/biophysics-week#/) organised annually by the American Biophysical Society with activities around the world. This year, the Biophysics Week promoted by the SBE in various Spanish universities surpasses all participating countries in the number of activities, even ahead of the USA.

Biophysics is the field that applies the theories and methods of physics to understand how biological systems work. To promote this scientific discipline among students at the University of Valencia, a session was held in the Darwin Room on Wednesday 25 March, which included the lecture "Engineering or Evolution? A View from the Frontier of Biophysics", a brilliant and particularly inspiring talk for younger people, delivered by CSIC research professor Susanna Manrubia (National Museum of Natural Sciences, CSIC, Madrid). Dr Manrubia gave an overview of her scientific career, which has taken her from her physics studies at the University of Barcelona and her doctoral thesis under the supervision of Ricard Solé, then at the UPC, through a variety of scientific institutions (including several Max Planck institutes, the Centre for Astrobiology and the National Centre for Biotechnology), to crossing disciplinary boundaries, including the physics of complex systems, ecology, cultural and linguistic evolution, or the evolutionary dynamics of viruses, to her current concern with the relationship between phenotype and genotype at various scales. All this, always from the rigorous perspective of a physical and mathematical mind.

The session was completed with a panel discussion in which, in addition to the speaker, the event's organisers participated: Javier Buceta (deputy director, Institute for Integrativa Systems Biology I2SysBio, CSIC-UV), Nuria Fuster (Institute for Corpuscular Physics IFIC, CSIC-UV), M. Jesús García-Murria (Intitute Biotecmed), moderated by the Dean of the Faculty of Biological Sciences, Ismael Mingarro. The day concluded with a pizza party in the bar of the Faculty of Pharmacy and Food Sciences to encourage communication among the more than one hundred participants.
