Superbugs are defeating antibiotics

Antibiotics have prevented and cured deadly human diseases for 80 years. But the time is coming when we might have to live without them -- if we can. The United Nations says it's finally time to take seriously the warning that overuse in human beings and farm animals is not just counter-productive. It's allowing bacteria to develop resistance, so that common conditions like tuberculosis, gonorrhea and urinary infections might well become fatal again. And pharmaceutical companies are not stepping up with new research that could lead to development of new drugs. After years of warnings, it's a global problem that demands solutions — while there's still time.
