A team of military medical scientists in China says it has 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.
The water bear, also known as tardigrade or moss piglet, is an eight-legged animal smaller than 1 millimetre long and the hardiest creature on Earth. Over years of scientific testing, it has survived -200 degrees Celsius, more than anour hour in boiling water and after flying in space.
The water bear’s toughness comes in part from a gene that can generate shieldlike proteins to protect its cells against radiation and other environmental damage.
