Weizmann Institute scientists have found what makes the bacterium Deinococcus radiodurans the most radiation-resistant organism in the world: The microbe's DNA is packed tightly into a ring. The findings, published in the January 10 issue of Science, solve a mystery that has long engaged the scientific community. The red bacterium can withstand 1.5 million rads-a thousand times more than any other life form on Earth and three thousand that of humans. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
