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:
“Making a logging-road in the Maine woods is called “swamping” it, and they who do the work are called “swampers.” I now perceived the fitness of the term. This was the most perfectly swamped of all the roads I ever saw. Nature must have coöperated with art here.”
—Henry David Thoreau (1817–1862)
