June 10, 2013 Is the world on the verge of a pandemic? There are three reasons to think so. Two flu viruses are active, and a virus that bears a resemblance to SARS has cropped up in the Middle East. Each has devastating potential, but many early warnings of past pandemics have failed to materialize.
June 6, 2013 At issue is a controversial study of more than 1,300 severely premature infants that looked at how much oxygen they should receive after birth. This spring, the federal Office for Human Research Protections criticized the scientists who ran the study for failing to tell parents enough about the risks.
June 4, 2013 The goal is to counter drug resistance, which is largely a consequence of antibiotics overuse. Supporters say the plan would entice companies back into the market because it would be much cheaper to gain approval. But critics call it "a tragedy of monumental proportions."
June 3, 2013 Tuberculosis is much less of a health threat in the United States than it is in other countries. But a family in Boston discovered that even here, no one is immune from this ancient foe. More than a dozen family members were infected with TB, and matriarch Judy Williams died at age 59.
