Twenty years ago, many scientists didn't think that genes could cause diseases like cancer. The discovery of the BRCA gene for hereditary breast cancer changed that. Mary-Claire King tells how.

It's not about making designer beer. Johns Hopkins scientists and undergrads stitched together strands of yeast DNA as a step in exploring the essential genetics of various species: What makes us us?

The organization of certain brain cells in children with autism seems already different from that of typical children by the sixth or seventh month of fetal development, a study hints.

Invasive weeds are already a big headache for ranchers, who spend thousands of dollars to get rid of them. New research shows that a changing climate is likely to help many of these weeds thrive.

The human nose may be able to distinguish more than a trillion different odors and fragrances, research hints. If true, our noses are much more discerning with smells than our eyes are with color.

As science becomes more diverse, scientific collaborators are growing more diverse, too. New research exploring the effect of this change suggests the diversity of the teams that produce scientific research play a big role in how successful the science turns out to be.

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.

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.

Layers of wax in the marine mammals' ears can be read like tree rings, scientists say, recording a whale's age and also information about pollutants in the water the whale swam through.

An enterprising grad student staged a striking photograph of Viking re-enactors pillaging through a park. NASA officials joined them — which led to multiple government investigations.

Journals usually require researchers to reveal genetic sequences for a toxin that is the subject of a scientific paper. The requirement was waived for a new botulinum toxin because of security risks.
