At its closest approach, the office building-sized asteroid will be only about 17,200 miles above the surface of our planet. Some people think this near miss should serve as a wake-up call.

Scientists say a Mississippi child has been cured of HIV. The research findings, released Sunday, could help cure other HIV-infected newborns.

Federal health officials warned that a dangerous group of superbugs has become increasingly common in hospitals. The bacteria are said to be resistant to virtually all antibiotics.

A government study of the medical records of 1,000 kids found no correlation between the number of vaccines a child received and his or her risk of autism spectrum disorder.
