  • "Active cloak" protects buildings from earthquakes

    Researchers say real objects could be cloaked by active cloaking — which means the technology uses devices that actively generate electromagnetic fields rather than being composed of “metamaterials” (exotic metallic substances) that passively shield objects from passing electromagnetic waves

  • All-titanium campus bridge show way for defense industry

    University of Akron, Defense Metals Technology Center co-sponsor design contest for titanium pedestrian bridge on university’s campus; titanium is a strong, lightweight, virtually corrosion-proof (but expensive) metal; a high-profile venture demonstrating titanium’s feasibility in commercial infrastructure projects could spark greater demand and open new markets for titanium
    ‘Avant-garde’ all-titanium span could spur other projects - and cut Pentagon’s costs
