Biology, the science of living organisms and their cycles of vitality. The area deals with all of life's physicochemical aspects. The new trend towards cross-disciplinary study and the unification of scientific expertise and research from various fields has contributed to a major overlap between the field of biology and other fields of science. In areas such as biochemistry, biomedicine, and biophysics, modern concepts of other disciplines, such as chemistry, medicine, and physics, are integrated with those of biology.
