Cryonics. Cryonics (from Greek: κρύος kryos meaning 'cold') is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of human remains, with the speculative hope that resurrection may be possible in the future. [1][2] Cryonics is regarded with skepticism within the mainstream scientific community.
Ötzi's posture in death (frozen body, face down, left arm bent across the chest) could support a hypothesis that, before death occurred and rigor mortis set in, the Iceman was turned onto his belly in the effort to remove the arrow shaft. [88] The Cambridge World History of Violence (2020) cited Ötzi as evidence of prehistoric warfare. [89]
Cryopreservation. Cryogenically preserved samples being removed from a dewar of liquid nitrogen. Cryopreservation or cryoconservation is a process where biological material - cells, tissues, or organs - are frozen to preserve the material for an extended period of time. [1] At low temperatures (typically −80 °C (−112 °F) or −196 °C ...

Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [2] Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. [3] In severe hypothermia, there may be hallucinations and paradoxical undressing, in which ...
Niflheim. In Norse cosmology, Niflheim or Niflheimr (Old Norse: [ˈnivlˌhɛimz̠]; "World of Mist", [1] literally "Home of Mist") is a location which sometimes overlaps with the notions of Niflhel and Hel. The name Niflheimr appears only in two extant sources: Gylfaginning and the much-debated Hrafnagaldr Óðins. Niflheim was primarily a ...
A brinicle (brine icicle, also known as ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice. As seawater freezes in the polar ocean, salt brine concentrates are expelled from the sea ice creating a downward flow of dense, extremely cold, saline water, with a ...
