Hormonal regulation of insect metamorphosis
A new reivew by Xavier Bellés for a non-specialist audience has been published at Investigación y Ciencia (in Spanish). He explains that the hormones responsible for this process are controlled by a complex network of reactions. Recently, an even finer level of control of this molecular system has been discovered.
Xavier Bellés is elected Secretary of the Biology Section of the Royal Academy of Science & Arts of Barcelona
The aim of RACAB is to act as a promoter and point of reference in the cultural arena and for catalan society in all that is relevant to the Applied Arts.
