Small changes in a cell’s composition can radically transform its function and drive the development of diseases like diabetes, cancer, or neuronal dysfunction. Scientists led by the European Molecular Biology Laboratory in Heidelberg, the Institute for Genetics of the University of Cologne, the Max Planck Institute for Biology of Ageing, and CECAD and the CMMC in Cologne have developed a method to study processes taking place in the cells of a living fruit fly larva. This technique, published in Nature Protocols on 10 February, provides a simple but effective way to study the functions of organs in living animals.
