A biologist is a professional who has specialized knowledge in the field of biology, understanding the underlying mechanisms that govern the functioning of biological systems within fields such as health, technology and the environment. [2] Biologists involved in fundamental research attempt to explore and further explain the underlying mechanisms that govern the functioning of living matter. Biologists involved in applied research attempt to develop or improve more specific processes and understanding, in fields such as medicine and industry.

Contents

Biologists are interested in understanding the underlying mechanisms that govern the functioning of living matter as well as the complex properties that emerge from the biophysical, biochemical, cellular and systemic interactions of living systems. Biologists conduct research using the scientific method to test the validity of a theory in a rational, unbiased and reproducible manner. This consists of hypothesis formation, experimentation and data analysis to establish the validity or invalidity of a scientific theory.

There are different types of biologists. Theoretical biologists use mathematical methods and develop models to understand phenomena and ideally predict future experimental results, while experimental biologists conceive experiments to test those predictions. [3] [4] Some biologists work on microorganisms, while others study multicellular organisms (including humans). Some investigate the nano or micro-scale, others emergent properties such as ecological interactions or cognition. There is much overlap between different fields of biology (e.g. zoology, microbiology, genetics and evolutionary biology) and due to the interdisciplinary nature of the field it is often difficult to classify a life scientist as only one of them. Many biological scientists work in research and development. Some conduct fundamental research to advance human knowledge of life. Furthermore, applied biological research often aids the development of solutions to problems in areas such as human health and the natural environment. Biological scientists mostly work in government, university, and private industry laboratories.

Biologists who work in basic research formulate theories and devise experiments to advance human knowledge on life including topics such as evolution, biochemistry, molecular biology, neuroscience and cell biology.

Biological scientists who work in applied research use instead the accomplishments gained by basic research to further knowledge in particular fields or applications. For example, this applied research may be used to develop new pharmaceutical drugs, treatments and medical diagnostic tests. Biological scientists conducting applied research and product development in private industry may be required to describe their research plans or results to non-scientists who are in a position to veto or approve their ideas. These scientists must consider the business effects of their work.

While theoretical biologists usually work in "dry" labs, formulating mathematical models and running computer simulations, some experimental biologists conduct laboratory experiments involving animals, plants, microorganisms or biomolecules. However, a small part of experimental biological research also occurs outside the laboratory and may involve natural observation rather than experimentation. For example, a botanist may investigate the plant species present in a particular environment, while an ecologist might study how a forest area recovers after a fire.

Swift advances in knowledge of genetics and organic molecules spurred growth in the field of biotechnology, transforming the industries in which biological scientists work. Biological scientists can now manipulate the genetic material of animals and plants, attempting to make organisms (including humans) more productive or resistant to disease. Basic and applied research on biotechnological processes, such as recombining DNA, has led to the production of important substances, including human insulin and growth hormone. Many other substances not previously available in large quantities are now produced by biotechnological means. Some of these substances are useful in treating diseases.

Those working on various genome (chromosomes with their associated genes) projects isolate genes and determine their function. This work continues to lead to the discovery of genes associated with specific diseases and inherited health risks, such as sickle cell anemia. Advances in biotechnology have created research opportunities in almost all areas of biology, with commercial applications in areas such as medicine, agriculture, and environmental remediation.

Specialists

Most biological scientists specialize in the study of a certain type of organism or in a specific activity, although recent advances have blurred some traditional classifications.[ why? ]

Working conditions

Biological scientists are not usually exposed to unsafe or unhealthy conditions. Those who work with dangerous organisms or toxic substances in the laboratory must follow strict safety procedures to avoid contamination. Many biological scientists, such as botanists, ecologists, and zoologists, conduct field studies that involve strenuous physical activity and primitive living conditions. Biological scientists in the field may work in warm or cold climates, in all kinds of weather.

Marine biologists encounter a variety of working conditions. Some work in laboratories; others work on research ships, and those who work underwater must practice safe diving while working around sharp coral reefs and hazardous marine life. Although some marine biologists obtain their specimens from the sea, many still spend a good deal of their time in laboratories and offices, conducting tests, running experiments, recording results, and compiling data.

Many biological scientists depend on grant money to fund their research. They may be under pressure to meet deadlines and to conform to rigid grant-writing specifications when preparing proposals to seek new or extended funding.

Biological scientists typically work regular hours. While the 40-hour workweek is common, longer hours are not uncommon. Researchers may be required to work odd hours in laboratories or other locations (especially while in the field), depending on the nature of their research.

Honors and awards

The highest honor awarded to biologists is the Nobel Prize in Physiology or Medicine, awarded since 1901, by the Royal Swedish Academy of Sciences. Another significant award is the Crafoord Prize in Biosciences; established in 1980.

Biology – The natural science that involves the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.

Zoology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek ζῷον, zōion, i.e. "animal" and λόγος, logos, i.e. "knowledge, study".

Environmental science The integrated, quantitative, and interdisciplinary approach to the study of environmental systems.

Environmental science is an interdisciplinary academic field that integrates physical, biological and information sciences to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.

Natural history Study of organisms including plants or animals in their environment

Natural history is a domain of inquiry involving organisms, including animals, fungi and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is called a naturalist or natural historian.

Biochemist Scientist specialized in biochemistry

Biochemists are scientists that are trained in biochemistry.

History of biology History of the study of life from ancient to modern times

The history of biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to ayurveda, ancient Egyptian medicine and the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. During the European Renaissance and early modern period, biological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms. Prominent in this movement were Vesalius and Harvey, who used experimentation and careful observation in physiology, and naturalists such as Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms. Antonie van Leeuwenhoek revealed by means of microscopy the previously unknown world of microorganisms, laying the groundwork for cell theory. The growing importance of natural theology, partly a response to the rise of mechanical philosophy, encouraged the growth of natural history.

Marine Biological Laboratory international center for research and education in biology, biomedicine and ecology

The Marine Biological Laboratory (MBL) is an international center for research and education in biological and environmental science. Founded in Woods Hole, Massachusetts in 1888, the MBL is a private, nonprofit institution affiliated with the University of Chicago. After being independent for most of its history, it became officially affiliated with the university on July 1, 2013. It also collaborates with numerous other institutions.

A biomedical scientist is a scientist trained in biology, particularly in the context of medicine. These scientists work to gain knowledge on the main principles of how the human body works and to find new ways to cure or treat disease by developing advanced diagnostic tools or new therapeutic strategies. The research of biomedical scientists is referred to as biomedical research.

The following outline is provided as an overview of and topical guide to ecology:

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis.
