Coldest Temperature That Life Can Survive
Scientific researchers from the British Antarctic Survey have found what they believe to be the lowest temperature under which life can still survive and grow. Life forms can exist on Earth in extreme conditions like ice cores, caves, and in the deepest parts of the ocean.
To test this, the researchers put single cell organisms in a watery environment and lowered the temperature to see when the organisms became vitrified, or unable to reproduce, which the scientists considered to be no longer living.
The researchers determined that negative 20 degrees Celsius is the lowest temperature the organisms could reproduce before becoming vitrified.
The results of the study help explain why deep freezing food preserves it and stops it from rotting, because bacteria and mold cannot multiply in such cold temperatures.
