Some cryoprotective agents used in research are inspired by plants and animals in nature that have unique cold tolerance to survive harsh winters, including: trees, [3] [4] wood frogs, [5] and tardigrades. [6] The first human corpse to be frozen with the hope of future resurrection was James Bedford's, a few hours after his cancer-caused death ...
Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C.

Salvia frigida is a herbaceous perennial in the family Lamiaceae. [1] It is native to northern Iraq, northwestern Iran, and eastern Turkey growing at 900 to 2,500 m (3,000 to 8,200 ft) elevation. It is often found growing in Anatolia, on woodland edges, meadows, limestone slopes, and crevices.
Since freezing belongs to dehydration stresses, cold acclimation process is associated with an enhanced accumulation of osmolytes (sugars, proline, polyamines, and hydrophilic proteins). [3] The loss of frost resistance occurs after warming. Rapid temperature fluctuations during winter deharden trees and increase the risk of spring damage. [5]
The Persians stored ice in a pit called a Yakhchal and may have been the first group of people to use cold storage to preserve food. In the Australian outback before a reliable electricity supply was available many farmers used a Coolgardie safe , consisting of a box frame with hessian (burlap) sides soaked in water.
Salvia farinacea, the mealycup sage, [1] or mealy sage, [2] is a herbaceous perennial native to Nuevo León, Mexico and parts of the United States including Texas and Oklahoma. [3] Violet-blue spikes rest on a compact plant of typically narrow salvia-like leaves; however, the shiny leaves are what set this species apart from most other Salvia ...
Additionally, wind chill can make a significant difference in staying safe out in the cold. “If [it’s] below -15 degrees Fahrenheit, it’s a good day to play inside.
