The Civic Movement could be the nucleus of a centrist party of the future. = core. Specialized structure occurring in most cells (except bacteria) and separated from the rest of the cell by the nuclear membrane. This membrane seems to be continuous with the cell's endoplasmic reticulum and has pores that permits the passage of large molecules. The nucleus controls and regulates the cell's activities (e.g., growth and metabolism) and carries the genes. Nucleoli are small bodies often seen within the nucleus that play an important part in the synthesis of RNA and protein. A cell normally contains only one nucleus. Central, positively charged core of an atom. It consists of positively charged protons and neutral neutrons, known collectively as nucleons, held together by the strong force. The number of nucleons can range from 1 to about 270, depending on the element. Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Some nuclei, especially heavier ones, are unstable, or radioactive (see radioactivity), emitting energy in the form of alpha rays (see alpha decay), beta rays (see beta decay), or gamma rays. The nucleus makes up nearly all the mass but only a minute fraction of the volume of the atom; A whole seed, as contained within the seed coats; It is more or less protoplasmic, and consists of a clear fluid (achromatin) through which extends a network of fibers (chromatin) in which may be suspended a second rounded body, the nucleolus (see Nucleoplasm); Literally, "little nut " It consists of neutrons and protons, occupies an infinitesimally small fraction of the total volume of an atom, and contains almost all of the mass of an atom

active galactic nucleus: Small region at the centre of a galaxy that emits a prodigious amount of energy in the form of radio, optical, X-ray, or gamma radiation or high-speed particle jets. Many classes of "active galaxies" have been identified; they appear similar in many respects to quasars. Astronomers suspect that the observed energy is generated as matter accretes onto a supermassive black hole with a mass millions or even billions of times that of the Sun. The accreting matter can outshine the rest of the galaxy as it is heated in very high-speed collisions outside the black hole's event horizon. It is believed that many galaxies harbour these central black holes and that they might have been quasars in their early history, although they now appear to be dormant unless orbiting matter is accreting onto the black hole
