Jars of Irradiated Russian Animals Find a New Purpose 86

scibri writes with bits and pieces from the article: "From the early 1950s to the end of the cold war, nearly 250,000 animals were systematically irradiated in the Russian town of Ozersk. Fearful of a nuclear attack by the United States, the Soviet Union wanted to understand how radiation damages tissues and causes diseases such as cancer. Now, these archives have become important to a new generation of radiobiologists, who want to explore the effects of the extremely low doses of radiation — below 100 millisieverts — that people receive during medical procedures such as computed-tomography diagnostic scans, and by living close to the damaged Fukushima nuclear reactors in Japan."

Soldier Re-Grows Leg Muscle After Experimental Procedure Screenshot-sm 141

Marine Isaias Hernandez has been able to grow back most of the missing muscle from his leg, including skeletal muscle, thanks to an experimental treatment involving an injection of a a growth promoting substance extracted from pig bladders. Hernandez lost 70% of his right thigh muscles from a mortar exploded attack in Afghanistan. Normally this type of injury would lead to an amputation. From the article: "In preparation for the operation, corporal Hernandez was made to build up the remaining 30 per cent of muscle left on the damaged thigh. Surgeons then sliced into the thigh, placing a thin slice of a substance called extracellular matrix. The surgery is the result of a $70 million investment by the US military into regenerative medicine research."
