In recent years, biotechnology has experienced an unprecedented revolution. The techniques that have been developed up until now, particularly in genetics, are opening up a wide range of new lines of research and promising applications. At the same time, these advances are uncovering new challenges for the field. Researcher Pere Puigdomènech spoke to local high school students in La Seu d'Urgell, in Spain’s Catalonia region, about the future of biotechnology, its opportunities, satisfactions, difficulties and new potential goals that involve not only researchers but also society at large.
