- Life Sciences (or Biological Sciences)

The life sciences (or biological sciences) comprise the branches of science that involve the scientific study of life and organisms – such as microorganisms, plants, and animals including human beings. Life science is one of the two major branches of natural science, the other being physical science, which is concerned with non-living matter. By definition, biology is the natural science that studies life and living organisms, with the other life sciences being its sub-disciplines.

Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and genetics. Some focus on the micro scale (e.g. molecular biology, biochemistry) other on larger scales (e.g. cytology, immunology, ethology, pharmacy, ecology). Another major branch of life sciences involves understanding the mind – neuroscience.

Life sciences discoveries are helpful in improving the quality and standard of life, and have applications in health, agriculture, medicine, and the pharmaceutical and food science industries.  Today, Life Sciences topics and tools are present in almost all disciplines of science and technology.

 

- Biology

Biology is the science of life. Its name is derived from the Greek words "bios" (life) and "logos" (study). It classifies and describes organisms, their functions, how species come into existence, and the interactions they have with each other and with the natural environment. Biologists study the structure, function, growth, origin, evolution and distribution of living organisms. 

There are many facets that point to the importance of biology. First and foremost, the science of biology is mainly studying about life. Second, it provides an in-depth, scientific understanding of how all living and nonliving organisms interact with each other. Third, it gives insights on how diverse life forms are. Moreover, biology encompasses other fields of research that are related to the sustainability of life, including the environment, ecosystem, food quality, causes of illnesses, the development of medicines, the study of the human body, to name a few.

- Biochemistry

Biochemistry is the application of chemistry to the study of biological processes at the cellular and molecular level. It is the study of the structure and function of biological molecules such as proteins, nucleic acids, carbohydrates and lipids. Biochemistry is also used to describe techniques suited to understanding the interactions and functions of biological molecules, including traditional techniques such as Western blotting, co-immunoprecipitation, and chromatography methods.

Biochemistry has become the foundation for understanding all biological processes. It has provided explanations for the causes of many diseases in humans, animals and plants.

 

- Biomedical Sciences

Biomedical sciences combine the fields of biology and medicine in order to focus on the health of both animals and humans. Biomedical sciences focuses on how cells, organs and systems function in the human body; an exciting and dynamic area that is highly relevant to the understanding and treatment of human diseases. For example, Biomedical Sciences focuses on Biochemistry, Genetics, and Genomics, Cancer Biology, Stem Cell Biology, Neurobiology, Cancer and DNA Repair, Cellular and Integrative Physiology, Translational Therapeutics, and Virology and Immunology.
