The study suggests that the random introduction of errors into proteins, rather than traditional natural selection, may have boosted the evolution of biological complexity. ... > full story
Herbal remedies offer hope as the new antibiotics (May 21, 2011) -- Cancer treatments often have the side effect of impairing the patient's immune system.
