-ics, -tics [-ac after i]
(Greek: a suffix that forms nouns and is usually used to form names of arts and sciences)
2. A combination of biology and photonics, with photonics being the science and technology of generation, manipulation, and detection of photons, quantum units of light.
Photonics is related to electronics in that it is believed that photons will play a similar central role in future information technology as electrons do today.
It includes the study or application of electromagnetic energy whose basic unit is the photon, incorporating optics, laser technology, electrical engineering, materials science, and information storage and processing.
2. The study of biological processes and materials by means of the theories and tools of physics.
3. The study of physical processes (e.g., electricity, luminescence) occurring in organisms.
4. The science that applies the laws and methods of physics to the study of biological processes.
5. The science dealing with the mechanical and electrical properties of the parts of living organisms.
For example, the principles of electricity have proven instructive in understanding the functions of nervous systems, while the laws of mechanics help to elucidate the workings of the musculoskeletal system.
Various physical techniques have advanced our knowledge of biologically important molecules (that is, proteins and nucleic acids), notably X-ray crystallography, nuclear magnetic resonance imaging, and spectroscopy.
2. The study of the structure of organisms in relation to their functions, as opposed to biodynamics.
2. Vital information or the numerical representation of conditions associated with life.
2. The study of the relationships among groups of species using criteria such as morphology, biochemistry, and DNA comparisons, especially to determine the evolutionary history of a species (used with a singular verb).
3. The area of systematics in which experimental taxonomic techniques are applied to investigate the relationships between taxa.
Such techniques include serological methods, biochemical analysis, breeding experiments, and cytological examination, in addition to the more established procedures of comparative anatomy.
Evidence from ecological studies may also be brought to bear.
2. Virtually all biotherapeutic agents in clinical use are biotech pharmaceuticals. A biotech pharmaceutical is simply any medically useful drug whose manufacture involves microorganisms or substances that living organisms produce (e.g., enzymes). Most biotech pharmaceuticals are recombinant‹that is, produced by genetic engineering. Insulin was among the earliest recombinant drugs.
3. In psychology, any form of treatment for abnormal behavior that alters the individual’s physiological processes; such as, electric shock treatment or surgery.
4. The treatment of disease with biologicals, that is, materials produced by living organisms.
2. The study of the interaction of sound at frequencies above about 20 000 hertz with living systems.
