      • Around the World

        In science news around the world this week, Egypt's political upheavals are threatening its famed antiquities, Intel is investing $100 million in computing and communications research, DOE is requesting big increases in two signature energy-research initiatives, 6000 transgenic dengue-fighting mosquitoes were released in Malaysia, preventive treatment was shown to reduce severe malaria in children up to age 5, CERN will wait another year before it shuts down the Large Hadron Collider for repairs, and 3000-year-old artifacts that were destroyed in a World War II bombing raid have been pieced back together and went on display in Berlin.

      • Random Sample

        "Bad Project," a lab-based parody of Lady Gaga's hit single "Bad Romance," has been viewed on YouTube more than 1.5 million times since it was posted on 20 January. Two hundred Cornell undergraduates swabbed their cheeks and submitted DNA samples to the Genographic Project, which tracks the history of human migration through DNA studies. And this week's numbers include funding to vaccinate children, carbon dioxide emissions, and university endowments.

COVER False-colored scanning electron micrograph of aligned zinc oxide nanowire arrays. Nanowires, each 10 to 50 nanometers in diameter and 0.5 to 1 micrometers long, have a variety of potential applications from medical diagnostics to miniature electronics. The Gordon Research Conference on Cancer Nanotechnology will be held 17 to 22 July 2011 at Colby College in Waterville, Maine. See page 602 for the conference schedule and preliminary programs.
