Although designer dogs are often selected by owners for their novelty, reputable breeders sometimes use crossbreeding in an attempt to reduce the incidence of certain hereditary problems found in
European Low Gravity Research Association France, Prof. L.G. Napolitano, Italy, Dr. J.F. Padday, UK, Dr. Stott, UK, Prof. H. Weiss, Germany and Dr. H.S. Wolff, UK) recognized the need for the European scientists involved in low gravity research to form an association to foster the cooperation and the coordination between them and to provide the ground-based expert advisory service for low gravity experiments. On June 18, 1979 the "European Low Gravity Research Association" ELGRA was born. Since its creation, ELGRA has continuously encouraged and promoted low gravity research in both life and physical sciences within Europe with the permanent support of the European Space Agency.
