Photobiology is the scientific study of the beneficial and harmful interactions of light (technically, non-ionizing radiation) in living organisms. [1] The field includes the study of photophysics, photochemistry, photosynthesis, photomorphogenesis, visual processing, circadian rhythms, photomovement, bioluminescence, and ultraviolet radiation ...
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs.
Luciferase. Luciferase is a generic term for the class of oxidative enzymes that produce bioluminescence, and is usually distinguished from a photoprotein. The name was first used by Raphaël Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. [1]
Lake Hawea, New Zealand. Limnology ( / lɪmˈnɒlədʒi / lim-NOL-ə-jee; from Ancient Greek λίμνη (límnē) 'lake', and -λογία ( -logía) 'study of') is the study of inland aquatic ecosystems. [1] The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural ...
Biological motion is motion that comes from actions of a biological organism. Humans and animals are able to understand those actions through experience, identification, and higher level neural processing. [1] Humans use biological motion to identify and understand familiar actions, which is involved in the neural processes for empathy ...
Molecular biology / m ə ˈ l ɛ k j ʊ l ər / is a branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions.
Corpuscular theory of light. In optics, the corpuscular theory of light states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess impetus. This was based on an alternate description of atomism of the time period.
Evolution is a light which illuminates all facts, a curve that all lines must follow. (p. 219 of The Phenomenon of Man) The phrase "nothing in biology makes sense except in the light of evolution" has come into common use by those opposing creationism or its variant called intelligent design. [5] [8] While the essay argues (following de Chardin ...
