Advances in the preservation of tissues, organs, sperm/eggs are revolutionizing medicine. Mehmet Toner is an international pioneer in this field. He describes the significance of the preservation-revival research, the different methods, and how the new breakthroughs will save lives and restore damaged tissue. Methods include specialized forms of supercooling and drying. Some of the models for these developments come from nature: organisms that transition to frozen or dehydrated states for extremely long periods –and then revive.
