Dear Reader, Check out highlights from today's top stories: A common bacterium that normally lives harmlessly in the gums appears to have a role in the spread of some cancers of the colon, esophagus, pancreas and—possibly—breast. Two years ago, planetary scientists reported the discovery of a large saltwater lake under the ice at Mars's south pole. Now, researchers say they've confirmed the presence of that lake—and found three more. The comparison of 100 tomato varieties' genetic sequences reveals more than 230,000 variations within their DNA. Understanding how these mutations modify tomatoes will give breeders and scientists new tools to refine this crop.
