    1. lants speak in a chemical vocabulary we can’t directly perceive or comprehend. The first important discoveries in plant communication were made in the lab in the nineteen-eighties, by isolating plants and their chemical emissions in Plexiglas chambers, but Rick Karban, the U.C. Davis ecologist, and others have set themselves the messier task of studying how plants exchange chemical signals outdoors, in a natural setting.

    1. We also show how our toolbox can be used to deploy the FBP in planta to build auto-luminescent reporters for the study of gene-expression and hormone fluxes

    1. placed at a 45° angle, nylon-mesh side up. Roots grew downward, collided with the bottom slide of the microcosm, and traveled along it. This method allowed observation of the root system by epifluorescence microscopy

      well explained!

    1. repeat expansion at IIL1 leads to increased accumulation of 24-nt siRNAs in a temperature-dependent manner that correlates with the iil phenotype. We show that DCL3 and other components of the RNA-dependent DNA methylation (RdDM) pathway are essential for this siRNA-directed epigenetic gene silencing

    1. Churchill Falls hydro-electric project
      The Churchill Falls hydro-electric project was inaugurated by Pierre Trudeau, the Canadian Prime Minister, on June 16, 1972. This hydro-electric plant was constructed between 1967 and 1975 and completed one year ahead of the predicted schedule. At the height of its construction, approximately 6,300 workers were present in the summer of 1970. The majority of construction occurred in the summer months, although construction continued year-round despite harsh conditions in Labrador where temperatures dipped to -21°C with a mean annual snowfall of 406 centimeters. The Churchill Falls power station is located in southern Labrador about 1,100 kilometers from an urban area. The Churchill Falls hydro-electric project was the largest hydro-electric project at the time, capable of generating 5,225 mW of electricity. It creates this energy by utilizing the water of the Churchill and Naskaupi Rivers which have a total catchment area of about 67,340 km2 combined. The underground power station is about 305 meters below ground. It uses eleven generators with a combined capacity of 5,225,000 kW. In order to utilize this harvested energy, large power lines capable of handling voltages up to 735 kV were put in place to transmit the energy from Churchill Falls to the Hydro-Quebec transmission system in the Manicouagan-Outardes hydro complex. The distance between these two stations is 606 kilometers. The energy from Churchill Falls was also transmitted via power lines to the Labrador City-Wabush area (Crabb, 1973).

    1. The next stage was the developing and preparing of avenues or mediums through which I couldexpress the manifold phases, possibilities and powers of My Idea.The outward evidence of this was what is known as the mineral, vegetable and animal kingdoms,which, each in turn, as it came into manifestation, gradually unfolded higher and more complexstates of consciousness that enabled Me more and more clearly to express the infinite phases andvariety of My Nature.It was at this stage that I looked upon My Creation, as stated in My other Revelation, and sawthat It was good

    1. In writing are the roots, in writing are the foundations of eloquence. By writing, resources are stored up, as it were, in a sacred repository, from where they may be drawn forth for sudden emergencies or as circumstances require.

      Writing is the foundation and the source from which we grow. Seems strange, distances writing from us, makes it seem something disconnected and inspired from some other force beyond us

    2. We must write, therefore, as carefully and as much as we can, for as the ground, by being dug to a great depth, becomes more fitted for fructifying and nourishing seeds, so improvement of the mind, acquired from more than mere superficial cultivation, pours forth the fruits of study in richer abundance and retains them with greater fidelity.

    1. they yet never fully attain to his force or fertility of language

      Those we imitate act as the fertile soil we grow from

    1. And as the generation of man is effected by both parents, and as you will in vain scatter seed unless the furrowed ground, previously softened, cherish it so, neither can eloquence come to its growth unless by mutual agreement between him who communicates and him who receives.
