Lily of The Valley - Lily of The Valley Phenomenon

Lily of The Valley Phenomenon

See also: bourgeonal

The odor of lily of the valley, specifically the ligand bourgeonal, attracts mammal sperm in a dramatic manner. The 2003 discovery of this phenomenon prompted a new wave of research into odor reception, but no evidence was found that the female sex organ has similar odors of any kind. A 2012 study demonstrated instead that at high concentrations, bourgeonal imitated the role of progesterone in stimulating sperm to swim (chemotaxis), a process unrelated to odor reception.

Famous quotes containing the words lily of, lily, valley and/or phenomenon:

    “It is not growing like a tree
    In bulk, doth make man better be,
    Or standing long an oak, three hundred year,
    To fall a log at last, dry, bald, and sere:
    A lily of a day
    Is fairer far in May
    Although it fall and die that night;
    It was the plant and flower of light.
    In small proportions we just beauties see,
    And in short measures life may perfect be.”
    —Ben Jonson (1572–1637)

    “Rejoice with the day lily for it is born for a day to live by the mailbox and glorify the roadside”
    —Anne Sexton (1928–1974)

    “The wide wonder of Broadway is disconsolate in the daytime; but gaudily glorious at night, with a milling crowd filling sidewalk and roadway, silent, going up, going down, between upstanding banks of brilliant lights, each building braided and embossed with glowing, many-coloured bulbs of man-rayed luminance. A glowing valley of the shadow of life. The strolling crowd went slowly by through the kinematically divine thoroughfare of New York.”
    —Sean O’Casey (1884–1964)

    “The teacher must derive not only the capacity, but the desire, to observe natural phenomena. In our system, she must become a passive, much more than an active, influence, and her passivity shall be composed of anxious scientific curiosity and of absolute respect for the phenomenon which she wishes to observe. The teacher must understand and feel her position of observer: the activity must lie in the phenomenon.”
    —Maria Montessori (1870–1952)
