At very low temperature.

A fluid that has a normal boiling point below –150°F (–101.1°C).

The study of phenomena and processes at low temperatures, defined arbitrarily as below 150K (-190ºF). Phenomena that occur at cryogenic temperatures include liquefaction and solidification of ambient gases.

Maintenance of frozen cells, usually in liquid nitrogen.

1. Structurally heterozygous individuals not identifiable on the basis of abnormal meiotic-chromosome pairing configurations ('cryptic structural hybrids').2. A form of polymorphism controlled by recessive genes ('cryptic polymorphism').3. Any mutation which is exposed by a sensitizing mutation and otherwise poorly detected (such mutations probably escape detection because of the plasticity of composition of the corresponding polypeptide).4. Phenotypically very similar species (cryptic species) which do not hybridize under normal conditions.5. Cryptic genetic variation refers to the existence of, for example, alleles conferring high performance for a trait, in a breed that has low performance for that trait.

The mathematical science of deliberately scrambling and unscrambling information. Information is protected by being transformed (encrypted) into an unreadable format, called cipher text. Only those who posses a secret key can decypher (or decrypt) that message into plain text.
