Biology, Biomedical Science, Biochemistry, and Biophysics
- [Greece - Dirk Bijstra]
- Overview
Biology is the broad study of living organisms, encompassing various subfields like biochemistry and biophysics, while Biomedical Science specifically applies biological knowledge to understand and treat human diseases; Biochemistry focuses on the chemical processes within living organisms, while Biophysics uses physics principles to study biological phenomena, essentially providing a more detailed molecular level understanding of biological processes within the larger framework of Biology and Biomedical Science.
- Biology: The overarching science studying life, including organisms, their structures, functions, growth, origin, evolution, and distribution.
- Biomedical Science: A field applying biological knowledge to human health, focusing on disease mechanisms, diagnostics, and treatment development.
- Biochemistry: A branch of biology that examines the chemical processes occurring within living organisms, including the structure and function of biomolecules like proteins, nucleic acids, and lipids.
- Biophysics: An interdisciplinary field combining biology and physics to study biological phenomena using physical principles and methods, often focusing on the mechanics and dynamics of biological systems at the molecular level.
Biology is the most encompassing term, with Biochemistry and Biophysics being specialized subfields within it. Biomedical science then leverages knowledge from these biological subfields to address human health concerns.
While biology might study organismal behavior, biochemistry would delve into the chemical reactions within a cell, and biophysics would analyze the physical forces governing those reactions.
Biomedical science translates the knowledge gained from biology, biochemistry, and biophysics into medical applications like drug development and disease diagnosis.
- The Age of Biology
With the spread of COVID-19 (2020), the future may be more uncertain now than at any time in recent memory. However, as we enter a new decade, along with uncertainty, the next decade presents tremendous opportunities for the pharmaceutical, biotech, medical device and regulatory industries.
If the 20th century was the age of computers, the 21st century may be the age of biology. The two might even merge. Hello, Synthetic Biology and Biocomputing!
Biochemistry and biophysics are closely related fields that use different scientific tools to study life. Biochemists study the chemical processes of living organisms, while biophysicists apply physics to biology. Both fields study the chemical and physical principles of living things, including cell development, growth, heredity, and disease.
Biomedicine is a science that applies natural or formal sciences to develop health care or public health knowledge, interventions, or technologies.
Biochemistry is a subfield of chemistry and biology. It studies the chemical processes within and associated with living organisms. Biochemistry can be divided into three areas: structural biology, enzymology, and metabolism.
Here are some of the most interesting things going on in biology right now: CRISPR and genetic engineering, Epidemiology and Coronavirus, Prion, Climate change, Cancer Biology, Behavioral economics, Endangered species recovery, Astrobiology, Synthetic biology, Apparent genetics. These biological topics are some of the hottest areas in scientific research today.
- Life Sciences
Life sciences include branches of science that involve the scientific study of life and organisms, such as Biology, Zoology, Botany, Ecology. Anatomy, Genetics, Molecular biology, Biochemistry, Cytology, Immunology, Ethology, Pharmacy, Neuroscience.
Life sciences are one of the two major branches of natural science, the other is physical science that focuses on non-living matter. By definition, biology is the natural science that studies life and living organisms, and other life sciences are its subdisciplines.
Some life sciences focus on specific types of organisms. 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 microscopic scale (e.g. molecular biology, biochemistry), while others focus on the larger scale (e.g. cytology, immunology, behavior, pharmacy, ecology). Another major branch of the life sciences involves understanding the mind - neuroscience.
Discoveries in the life sciences help improve the quality and standard of life and have applications in the health, agriculture, medicine, and pharmaceutical and food science industries. Today, life science topics and tools exist in nearly all scientific and technological disciplines.
Life sciences is a multi-disciplinary field, and professionals often work together from different backgrounds to develop new solutions. For example, biologists, chemists, and robotics engineers may collaborate on projects.
- Biology and Biological Sciences
Biology is essentially the core study of life and living organisms, while biological science is a broader term encompassing various fields within biology, including genetics, microbiology, ecology, biochemistry, and more, essentially referring to the scientific study of life at a wider range of levels and perspectives; so, biological science is a more comprehensive term that includes biology as its foundational discipline.
- Biology is the core: If you study "biology," you're primarily focusing on the fundamental principles of life, like cell structure, organismal function, and basic evolutionary concepts.
- Biological science is broader: "Biological science" encompasses not only the core biology concepts but also specialized areas like molecular biology, developmental biology, immunology, and environmental biology.
Biology is the science of life. It takes its name from the Greek words "bios" (to live) and "logos" (to learn). It classifies and describes organisms, their functions, how species exist, and how they interact with each other and with the natural environment. Biologists study the structure, function, growth, origin, evolution and distribution of organisms.

- Biochemistry
Biochemistry is the study of the chemical processes and components of living organisms. Biochemistry is a combination of biology and chemistry, and it covers a range of scientific disciplines, including genetics, microbiology, plant science, and medicine.
Biochemistry is used in many scientific and medical fields, including forensics, nutrition, and pharmaceuticals. For example, biochemical tests measure substances in blood and urine to help diagnose diseases and determine treatments.
Biochemists study the structure, composition, and chemical reactions of biomolecules like proteins, DNA, RNA, lipids, and sugars. They also study how these molecules interact with each other and how cells communicate.
Biochemists use laboratory experiments to isolate substances from living cells, determine their chemical properties, and then put them back together to see how they interact.
Biochemistry's origins can be traced back to the study of fermentation processes, such as the transformation of sugar into alcohol by yeast.
Biochemistry has become the basis for understanding all biological processes. It provides explanations for the causes of many diseases in humans, animals and plants. For the past nine decades, chemistry has played a central role in determining the structure and chemical reactivity of building blocks used by all organisms, providing a molecular framework for elucidating the pathways involved in central metabolism.
- Biomedical Sciences
Biomedical sciences is a field that uses natural and formal sciences to create knowledge, technology, and interventions for healthcare and public health.
Some areas of biomedical science include:
- Neuroscience: This field includes the study of neuronal cell biology, the development of the nervous system, physiology, anatomy, and more.
- Cancer biology: This field studies biochemistry, genetics, molecular and cell biology, and the clinical aspects of cancer. The goal is to improve the prevention, diagnosis, and treatment of cancer.
- Immunology: This field includes teaching the body how to fight off certain diseases and developing antibodies to protect against others.
- Genetics: This field is the basis for all of biology and is one of the fastest evolving fields in biomedical research.
- Pharmacology: This field includes the study of drug discovery, toxicology, endocrinology, and how drugs interact with cells, tissues, and targets.
Biomedical scientists use knowledge of engineering, biology, and biomechanical principles to design, develop, and evaluate biological and health systems and products.
- Biophysics
Biophysics is a scientific field that uses physics, chemistry, and mathematics to study biological systems:
Biophysics examines the structure, interactions, dynamics, and function of biological systems at all scales, from molecules to organisms and populations. Biophysicists use the principles and techniques of physics, as well as related sciences like physical chemistry, electrical engineering, mathematics, and computer science, to understand how biological systems work.
Biophysics has been critical to understanding how molecules of life are made, how cells move and function, and how complex systems like the brain, immune system, and circulation work. Scientists from many fields, including math, chemistry, physics, engineering, pharmacology, and materials sciences, use their skills in biophysics.
Biophysics is a scientific field at the forefront of research that is changing our understanding of biology and the practice of medicine in magnificent ways. Biophysics is the field of applying physical theories and methods to understand how biological systems work.
Biophysics is critical for understanding how life's molecules are made, how different parts of a cell move and function, and how our complex systems (brain, circulation, immune system, etc.) work. Biophysics is a dynamic field of science where scientists from many fields including mathematics, chemistry, physics, engineering, pharmacology and materials science use their skills to explore and develop new tools to understand biology - all life - How it works.
