...cetta, "Verardo's work is important because he has uncovered a record of burning that goes beyond historical records, so we can study natural burning before human influence." This in turn will help scientists determine whether human-induced burning has different effects than natural burning, and how burning i...Researchers Find How Disease-resistant Plants Recognize Bacteria
...ETTE, Ind. -- Scientists at Purdue University have uncovered how plants that are resistant to disease recognize disease-causing microbes, a development that experts predict will lead to crops that are better able to resist disease naturally.
