Twenty years ago two life sciences, biology and medicine, were isolated from each other and relied on their own specific tools. Physiology was isolated from biochemistry; biophysics and molecular biology did not have much in common. The invention, of Internet, increased rates and improved performance of molecular technologies resulted in the fusion of stand-alone sciences. Now all significant research is complex and comprehensive in terms of its methodology and objects. Biomedicine can be depicted as a graph whose faces represent a combination of different methods and systems. By saying that I mean that a modern researcher must be broadminded and bear in mind various aspects of many different fields, from zoology to nuclear physics, no matter how difficult it is. Unlike business, science is based on cooperation more than competition. The idea of open databases very much agrees with this statement. In genomics, propeomics and other -omics I have been dealing with, extensive data sharing has become common and is a requirement for serious publications. Compete but do not forget to cooperate. And remember that biology has started in nature.
