According to details, the military scientists say they've successfully "inserted a gene from the microscopic water bear into human embryonic stem cells and significantly increased these cells’ resistance to radiation." "They said success in this unprecedented experiment could lead to super-tough soldiers who could survive nuclear fallout," SCMP writes. The initiative involved the experimental introduction into human DNA (utilizing embryonic cells) of a key gene found the water bear. They also foresee the era of the future 'super soldier' and genetically altered humans capable of surviving nuclear apocalypse.
