William D. McElroy
William David McElroy (22 January 1917 – 17 February 1999) was an American biochemist and academic administrator. Biography Early years McElroy was born to William D. McElroy and Ora Shipley in Rogers, Texas. After graduating from McAllen High School in McAllen, Texas in 1935, he attended Pasadena Junior College in California, and went on to Stanford University on a football scholarship where he received his bachelor's degree in 1937. He earned his master's degree in biology at Reed College and his PhD at Princeton University in 1943. Career After college, McElroy became a professor at Johns Hopkins University. He initiated an independent research program in bioluminescence, recruiting students to collect fireflies to perform experiments. He discovered the key role that luciferase and adenosine triphosphate (ATP) play in the process. He began working with the Office of Naval Research and the National Institute of Health in the 1950s, and became a member of the President' ...

National Institute Of Health
The National Institutes of Health, commonly referred to as NIH (with each letter pronounced individually), is the primary agency of the United States government responsible for biomedical and public health research. It was founded in the late 1880s and is now part of the United States Department of Health and Human Services. The majority of NIH facilities are located in Bethesda, Maryland, and other nearby suburbs of the Washington metropolitan area, with other primary facilities in the Research Triangle Park in North Carolina and smaller satellite facilities located around the United States. The NIH conducts its own scientific research through the NIH Intramural Research Program (IRP) and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program. , the IRP had 1,200 principal investigators and more than 4,000 postdoctoral fellows in basic, translational, and clinical research, being the largest biomedical research institut ...

President's Science Advisory Committee
The President's Science Advisory Committee (PSAC) was created on November 21, 1957, by President of the United States Dwight D. Eisenhower, as a direct response to the Soviet launching of the Sputnik 1 and Sputnik 2 satellites. PSAC was an upgrade and move to the White House of the Science Advisory Committee (SAC) established in 1951 by President Harry S. Truman, as part of the Office of Defense Mobilization (ODM). Its purpose was to advise the president on scientific matters in general, and those related to defense issues in particular. Eisenhower appointed James R. Killian as PSAC's first director. In 1961, President John F. Kennedy renamed the agency the Office of Science and Technology (OST). This lasted until Richard Nixon's administration in 1973. In 1976 the Office of Science and Technology Policy was established. First report The first report of the newly formed Science Advisory Committee, commonly known as the Killian Report (February 14, 1955, officially "Meeting the Thre ...

Adenosine Triphosphate
Adenosine triphosphate (ATP) is an organic compound that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis. Found in all known forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. When consumed in metabolic processes, it converts either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP). Other processes regenerate ATP. The human body recycles its own body weight equivalent in ATP each day. It is also a precursor to DNA and RNA, and is used as a coenzyme. From the perspective of biochemistry, ATP is classified as a nucleoside triphosphate, which indicates that it consists of three components: a nitrogenous base (adenine), the sugar ribose, and the Polyphosphate, triphosphate. Structure ATP consists of an adenine attached by the 9-nitrogen atom to the 1′ carbon atom of a sugar (ribose), which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Both words are derived from the Latin word ''lucifer'', meaning "lightbearer", which in turn is derived from the Latin words for "light" (''lux)'' and "to bring or carry" (''ferre)''.Luciferases are widely used in biotechnology, for bioluminescence imaging microscopy and as reporter genes, for many of the same applications as fluorescent proteins. However, unlike fluorescent proteins, luciferases do not require an external light source, but do require addition of luciferin, the consumable substrate. Examples A variety of organisms regulate their light production using different luciferases in a variety of light-emitting reactions. The majority of studied luciferases have been found in animals, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireflies
The Lampyridae are a family (biology), family of Elateroidea, elateroid beetles with more than 2,000 described species, many of which are bioluminescence, light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly crepuscular, during twilight, to attract mates. Light production in the Lampyridae is thought to have originated as an honest signal, honest Aposematism, warning signal that the larvae were distasteful; this was co-opted in evolution as a mating signal in the adults. In a further development, female fireflies of the genus ''Photuris'' mimic the flash pattern of ''Photinus (beetle), Photinus'' species to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. While all known fireflies glow as larvae, only some species produce light in their adult stage, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
