"Cryobiology is the branch of biology that studies the effects of low temperatures on living things within Earth's cryosphere or in science. The word cryobiology is derived from the Greek words \u03BA\u03C1\u1FE7\u03BF\u03C2 [kryos], \u00AB cold \u00BB, \u03B2\u03AF\u03BF\u03C2 [bios], \u00AB life \u00BB, and \u03BB\u03CC\u03B3\u03BF\u03C2 [logos], \u00AB word \u00BB (hence science). In practice, cryobiology is the study of biological material or systems at temperatures below normal. Materials or systems studied may include proteins, cells, tissues, organs, or whole organisms."@en .
