Science / Chemistry / Nuclear Fission: Splitting of a nucleus into two smaller nuclei and neutrons. The smaller nuclei have higher binding energy than the original nucleus, and fission results in the release of energy.

Science / Biology / Nuclear Pores: Openings in the membrane of a cells nuclear envelope that allow the exchange of materials between the nucleus and the cytoplasm. MORE
Science / Chemistry / Nuclear Fusion: Combination of two smaller nuclei to form a larger nucleus. The larger nucleus has higher binding energy per nucleon than the original nuclei, and fusion results in the release of energy. MORE
Science / Genetics / Nuclear Transfer: A laboratory procedure in which a cell's nucleus is removed and placed into an oocyte with its own nucleus removed so the genetic information from the donor nucleus controls the resulting cell. Such c MORE
Science / Geology / Thermonuclear Reaction: A reaction in which atomic nuclei fuse into new elements with a large release of heat: especially a reaction that is self-sustaining. Occasionally used to include fission reactions as well. MORE
Science / Geology / Nuclear Fuel: Fissionable materials that are rich enough to sustain a fission chain reaction. MORE
