Cryopreservation in Nature
Many living organisms are able to tolerate prolonged periods of time at temperatures below the freezing point of water. Most living organisms accumulate cryoprotectants such as anti-nucleating proteins, polyols, and glucose to protect themselves against frost damage by sharp ice crystals. Most plants, in particular, can safely reach temperatures of −4 °C to −12 °C.

Famous quotes containing the word nature:
“The Nature of Familiar Letters, written, as it were, to the Moment, while the Heart is agitated by Hopes and Fears, on Events undecided, must plead an Excuse for the Bulk of a Collection of this Kind. Mere Facts and Characters might be comprised in a much smaller Compass: But, would they be equally interesting?”
—Samuel Richardson (1689–1761)
