A profile of teenage pregnancy in SpainThe effective use of contraception once becoming sexually active is the best way to avoid unwanted pregnancy during adolescence. This is just one of the conclusions of a study by the Spanish National Research Council (CSIC) and the Universidad Complutense in Madrid which additionally reveals that using no contraception or using it well after starting sexual relations increases up to six times the risk for teen pregnancy.

Gene may be Key to Kidney CancerScientists at Mayo Clinic's campus in Florida have discovered a key gene that, when turned off, promotes the development of common kidney cancer. Their findings suggest that a combination of agents now being tested in other cancers may turn the gene back on, providing a much-needed treatment for the difficult-to-treat cancer.
