The life sciences comprise all fields of science that involve the scientific study of living organisms, like plants, animals, and human beings. However, the study of behaviour of organisms, such as practised in ethology and psychology, is only included in as much as it involves a clearly biological aspect. While biology and medicine remain centerpieces of the life sciences, technological advances in molecular biology and biotechnology have led to a burgeoning of specializations and new, often interdisciplinary, fields. The following is an incomplete list of life science fields, as well as topics of study in the life sciences, in which several entries coincide with, are included in, or overlap with other entries Biological engineering, biotechnological engineering or bioengineering (including biological systems engineering) is the application of concepts and methods of physics, chemistry, and mathematics to solve problems in life sciences, using engineering’s own analytical and synthetic methodologies. In this context, while traditional engineering applies physical and mathematical sciences to analyze, design and manufacture inanimate tools, structures and processes, bioengineering uses the same sciences to study many aspects of living organisms. Usually it is used to analyze and solve problems related to human health. Biological engineering is a science-based discipline founded upon the biological sciences in the same way that chemical engineering, electrical engineering, and mechanical engineering are based upon chemistry, electricity and magnetism and statics, respectively.
