Areas of Interest
The interactions between organisms and electromagnetic fields (EMF) and ionizing radiation can be studied in a number of ways:
- Radiation physics
- Radiation chemistry
- molecular and cell biology
- Molecular genetics
- Cell death and apoptosis
- Dose modifying agents
- Protection and repair mechanisms
- Tissue responses to radiation
- Radio-adaptation of living organisms
- High and low-level electromagnetic radiation and health
- Specific absorption rates of organisms
- Radiation poisoning
- Radiation oncology (radiation therapy in cancer)
- Bioelectromagnetics
- Electric field and Magnetic field - their general nature.
- Electrophysiology - the scientific study of the electrical properties of biological cells and tissues.
- Biomagnetism - the magnetic properties of living systems (see, for example, the research of David Cohen using SQUID imaging) and Magnetobiology - the study of effect of magnets upon living systems. See also Electromagnetic radiation and health
- Bioelectromagnetism - the electromagnetic properties of living systems and Bioelectromagnetics - the study of the effect of electromagnetic fields on living systems.
- Electrotherapy
- Radiation therapy
- Electroconvulsive therapy
- Transcranial magnetic stimulation - a powerful electrical current produces a transient, spatially focussed magnetic field that can penetrate the scalp and skull of a subject and induce electrical activity in the neurons on the surface of the brain.
- Magnetic resonance imaging - a very powerful magnetic field is used to obtain a 3D image of the density of water molecules of the brain, revealing different anatomical structures. A related technique, functional magnetic resonance imaging, reveals the pattern of blood flow in the brain and can show which parts of the brain are involved in a particular task.
- Embryogenesis, Ontogeny and Developmental biology - a discipline that has given rise to many scientific field theories.
- Bioenergetics - the study of energy exchange on the molecular level of living systems.
- Biological psychiatry, Neurology, Psychoneuroimmunology
- Bioluminescence - a marked phosphoresecence found in fungi, deep-sea creatures etc., as against Biophoton - a much weaker electromagnetic radiation, thought by Alexander Gurwitsch, its discoverer, to be a form of signalling.
The activity of biological and astronomical systems inevitably generates magnetic and electrical fields, which can be measured with sensitive instruments and which have at times been suggested as a basis for "esoteric" ideas of energy.

Famous quotes containing the words areas of, areas and/or interest:
“Helping children at a level of genuine intellectual inquiry takes imagination on the part of the adult. Even more, it takes the courage to become a resource in unfamiliar areas of knowledge and in ones for which one has no taste. But parents, no less than teachers, must respect a child’s mind and not exploit it for their own vanity or ambition, or to soothe their own anxiety.”
—Dorothy H. Cohen (20th century)
“In my writing I am acting as a map maker, an explorer of psychic areas ... a cosmonaut of inner space, and I see no point in exploring areas that have already been thoroughly surveyed.”
—William Burroughs (b. 1914)
“Take it all around, I was feeling ruther comfortable, on accounts of taking all this trouble for that gang, for not many would a done it. I wished the widow knowed about it. I judged she would be proud of me for helping these rapscallions, because rapscallions and dead beats is the kind the widow and good people takes the most interest in.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
