    Here is the word of the day from Dictionary.com. I thought it was very appropriate for this forum.



    April 3, 2012



    zeitgeber TSAHYT-gey-ber, noun:



    An environmental cue, as the length of daylight, that helps to regulate the cycles of an organism's biological clock.



    The light–dark transition Zeitgeber is widely used by plants to set internal clocks not just for leaf movement but for many other activities as well.

    -- John King, Reaching for the Sun



    The most prominent zeitgeber in humans is the light/dark cycle.

    -- Harold R. Smith, Cynthia Comella, Birgit Högl, Sleep Medicine

    grokGRAHK



    verb : to understand profoundly and intuitively



    The novel's protagonists are driven by a desire to grok their place in the grand scheme of the universe.



    "Both of these views completely fail to grok both the documented benefits of America's leadership in space and the font of inspiration for visionaries … who have aspired to send people there." — From an article by Greg Autry in Political Machine, February 2, 2012

    To grok (play /ˈɡrɒk/) is to intimately and completely share the same reality or line of thinking with another physical or conceptual entity. Author Robert A. Heinlein coined the term in his best-selling 1961 book Stranger in a Strange Land. In Heinlein's view, grokking is the intermingling of intelligence that necessarily affects both the observer and the observed. From the novel:



    Grok means to understand so thoroughly that the observer becomes a part of the observed—to merge, blend, intermarry, lose identity in group experience. It means almost everything that we mean by religion, philosophy, and science—and it means as little to us (because of our Earthling assumptions) as color means to a blind man.



    The Oxford English Dictionary defines grok as "to understand intuitively or by empathy; to establish rapport with" and "to empathise or communicate sympathetically (with); also, to experience enjoyment". Other forms of the word include groks (present third person singular), grokked (past participle) and grokking (present participle).



    In an ideological context, a grokked concept becomes part of the person who contributes to its evolution by improving the doctrine, perpetuating the myth, espousing the belief, adding detail to the social plan, refining the idea or proving the theory.

    Today's Word of the Day



    phosphorylation /phos·phor·y·la·tion/ (fos-for″ĭ-la´shun) the metabolic process of introducing a phosphate group into an organic molecule.

    - oxidative phosphorylation the formation of high-energy phosphate bonds by phosphorylation of ADP to ATP coupled to the transfer of electrons from reduced coenzymes to molecular oxygen via the electron transport chain; it occurs in the mitochondria.

    - substrate-level phosphorylation the formation of high-energy phosphate bonds by phosphorylation of ADP to ATP (or GDP to GTP) coupled to cleavage of a high-energy metabolic intermediate.



    As used in Dr K's Quilt http://jackkruse.com/the-quilthow-to-beat-agin/

    Levee 7:



    ROS generation. ROS stands for Reactive Oxygen Species generation. We all know life is based upon energy production from the use of oxygen. This process is called oxidative phosphorylation
    . Examples of ROS include oxygen ions and peroxides. Oxygen species are highly reactive due to the presence of unpaired outer shell electrons. ROS forms as a natural byproduct of the normal metabolism of oxygen and has important roles in cell signaling and homeostasis. This process occurs in the mitochondria. When we generate energy packages, adenosine triphosphate (ATP), from nutrients, we also generate free radicals of oxygen that leak from the cytochromes of our mitochondria. Cytochromes are the furnaces in mitochondria where ATP is made. This “leakiness” is critical to life and to the death programs inside our cell. The more “leaky” our mitochondria the more ROS we generate. Generally ROS is a bad omen for the cell but it can also signal the cell to lengthen its telomeres at times or to recruit the formation of new mitochondria to make energy. ROS generation is a measure of cellular stress, and that stress can be so great that is can damage cellular structures so that they no longer work properly. Examples are UV exposure or radiation exposure.



    In general, lower ROS is better for longevity of the cell and for it to function optimally. A simple example of this fact is coenzyme Q10. Most people have heard of this cofactor, and this protein is used up to a great degree when you are making energy or the cell is stressed. Statin drugs cause depletion of this protein because of their mode of action on enzymes in blocking the building blocks of cholesterol, so they cause the cell to be more inefficient making energy as the CoEnQ10 is depleted. It is also used up when we are under stress due to long term insulin or cortisol secretion. Depletion of CoEq10 is why people can get cognitive change and muscle cramping when they are on statins too long or the dose becomes too high. The cause is because the cells in that part of the body can’t make the energy they require because of the side effect of the drug. Therefore many patients are told to add CoEnQ10 to their supplement list daily if they are on a statin.

    I nominate: Zakalyatsa: Russian cold adaptation as submitted in the CT thread by PaleoDentist, born in northern Russia; immigrated to the US when 9. The post says that:



    ZAKALYATSA basically means cold adapted.



    The description is very compelling:



    I went to my parents house for Passover dinner on Saturday. there were a bunch of their friends, all Russian, ranging in ages form 55-75. I asked them about the meaning of the word and the the process. The general consensus was this: zakatyatsa is done to improve the immune system and people who practice this never get sick in winter. basically it is people who tolerate the cold or are able to withstand the cold. they spoke about taking cold showers, splashing themselves with cold water in the morning, swimming in cold water. they said the epitome of this practice are people who swim in ice cold water in the winter. they are called "seals". In the US, we call this "the polar bear club".

    littoral LIT-er-uhl, adjective:



    1. Pertaining to the shore of a lake, sea, or ocean.

    2. (On ocean shores) of or pertaining to the biogeographic region between the sublittoral zone and the high-water line and sometimes including the supralittoral zone above the high-water line.

    3. Of or pertaining to the region of freshwater lake beds from the sublittoral zone up to and including damp areas on shore.



    noun:

    1. A littoral region.



    The extensive artificialization of lake shorelines reduces the native littoral vegetation in quantity and quality.

    -- Alex Córdoba-Aguilar, Dragonflies and Damselflies

    There was an exuberant fierceness in the littoral here, a vital competition for existence.

    -- John Steinbeck, The Grapes of Wrath

    Littoral stems from the Latin word lītus which meant "shore." It was replaced by the Old English word shore but is still used by scientists.
