High blood pressure easy to miss in children with kidney disease
Spot blood pressure readings in children with chronic kidney disease often fail to detect hypertension -- even during doctor's office visits -- increasing a child's risk for serious heart problems, according to research from Johns Hopkins Children's Center and other institutions.

It's a gas: New discovery may lead to heartier, high-yielding plants
In a research report in the November 2009 journal Genetics, scientists show how a family of genes (1-aminocyclopropane-1-carboxylate synthase, or ACS genes), in the weed Arabidopsis thaliana, are responsible for production of ethylene. This gas affects many aspects of plant development, and this information, which will be applicable to other plants, lays the foundation for future genetic manipulation that could make plants disease resistant, able to survive and thrive in difficult terrain, and increase yields.Ask a question about this article
