Israeli scientists successfully transplant frozen-thawed ovaries in sheep
... using a technique they have developed that allows precise control over the propagation of ice crystals during the freezing process, thus reducing the damage caused to cells by conventional methods[4]. Sheep were chosen because their ovaries are similar to those of humans. The technique worked the frozen-th...New tooth enamel dating technique could help identify disaster victims
