A clinical trial funded by the National Institutes of Health will evaluate a male contraceptive gel for its ability to prevent pregnancy. The gel formulation was developed by the Population Council and NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).“Many women cannot use hormonal contraception and male contraceptive methods are limited to vasectomy and condoms,” said study investigator Diana Blithe, Ph.D., chief of NICHD’s Contraceptive Development Program. “A safe, highly effective and reversible method of male contraception would fill an important public health need.” more »

Julia Sneden wrote: The name Grandabbie was my own invention. I don’t remember how I came up with the solution of combining Grandmother and Abbie into what was to become her label for life. From that time on, we called her Grandabbie, and so did all our friends and most of our neighbors. Poor Grandabbie: she used to tell me: “All my life, I looked forward to being called Grandmother. It’s a beautiful word. But then,” she would sigh, “I hadn’t reckoned with you.” more »

Previous missions to Mars have investigated the surface history of the Red Planet by examining features like canyons, volcanoes, rocks and soil. However, signatures of the planet's formation can only be found by sensing and studying its "vital signs" far below the surface. In comparison to the other terrestrial planets, Mars is neither too big nor too small. This means that it preserves the record of its formation and can give us insight into how the terrestrial planets formed. It is the perfect laboratory from which to study the formation and evolution of rocky planets. Scientists know that Mars has low levels of geological activity. But a lander like InSight can also reveal just how active Mars really is. more »

The continued warming that is projected to occur without substantial and sustained reductions in global greenhouse gas emissions is expected to cause substantial net damage to the U.S. economy throughout this century, especially in the absence of increased adaptation efforts. With continued growth in emissions at historic rates, annual losses in some economic sectors are projected to reach hundreds of billions of dollars by the end of the century — more than the current gross domestic product (GDP) of many U.S. states. more »
