Beatrice M. Sweeney
Eleanor Beatrice Marcy "Beazy" Sweeney (–) was an American plant physiologist and a pioneering investigator into circadian rhythms. At the time of her death she was professor emerita at the University of California, Santa Barbara, where she had worked since 1961. Having started her career as a botanist, serendipity led her to dinoflagellate research. She investigated circadian rhythms in photoluminescent dinoflagellates, and other single celled organisms. Later in her career she served as a senior officer in many scientific organizations, including the American Association for the Advancement of Science and the American Institute of Biological Sciences. Early life and education Sweeney was born Eleanor Beatrice Marcy on in Boston, Massachusetts, the daughter of Eleanor and Henry O. Marcy Jr. She gained her undergraduate degree at Smith College where she performed research into the effect of drugs on cytoplasmic streaming. She attended graduate school at Radcliffe College ...

Photoluminescence
Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom), hence the prefix ''photo-''. Following excitation, various relaxation processes typically occur in which other photons are re-radiated. Time periods between absorption and emission may vary: ranging from short femtosecond-regime for emission involving free-carrier plasma in inorganic semiconductorsHayes, G.R.; Deveaud, B. (2002).

College Of Creative Studies
The College of Creative Studies is the smallest of the three undergraduate colleges at the University of California, Santa Barbara, unique within the University of California system in terms of structure and philosophy. Its small size, student privileges, and grading system are designed to encourage self-motivated students with strong interests in a field to accomplish original work as undergraduates. A former student has called it a “graduate school for undergraduates”. The college has roughly 350 students in eight majors and approximately 60 professors and lecturers. There is an additional application process to the standard UCSB admission for prospective CCS students, and CCS accepts applications for admissions throughout the year. History In the late 1960s, the Chancellor of UCSB, Vernon I. Cheadle, was looking for an alternative education program for undergraduate students which could embody the new thinking of the 60s and also attract attention to his growing unive ...

Auxin
Auxins (plural of auxin ) are a class of plant hormones (or plant-growth regulators) with some morphogen-like characteristics. Auxins play a cardinal role in coordination of many growth and behavioral processes in plant life cycles and are essential for plant body development. The Dutch biologist Frits Warmolt Went first described auxins and their role in plant growth in the 1920s. Kenneth V. Thimann became the first to isolate one of these phytohormones and to determine its chemical structure as indole-3-acetic acid (IAA). Went and Thimann co-authored a book on plant hormones, ''Phytohormones'', in 1937. Overview Auxins were the first of the major plant hormones to be discovered. They derive their name from the Greek word αυξειν (''auxein'' – "to grow/increase"). Auxin is present in all parts of a plant, although in very different concentrations. The concentration in each position is crucial developmental information, so it is subject to tight regulation through both meta ...

Cytoplasmic Streaming
Cytoplasmic streaming, also called protoplasmic streaming and cyclosis, is the flow of the cytoplasm inside the cell, driven by forces from the cytoskeleton. It is likely that its function is, at least in part, to speed up the transport of molecules and organelles around the cell. It is usually observed in large plant and animal cells, greater than approximately 0.1 mm. In smaller cells, the diffusion of molecules is more rapid, but diffusion slows as the size of the cell increases, so larger cells may need cytoplasmic streaming for efficient function. The green alga genus ''Chara'' possesses some very large cells, up to 10 cm in length, and cytoplasmic streaming has been studied in these large cells. Cytoplasmic streaming is strongly dependent upon intracellular pH and temperature. It has been observed that the effect of temperature on cytoplasmic streaming created linear variance and dependence at different high temperatures in comparison to low temperatures. This ...
