• Day of ultra-clean engine nears

    One of the major obstacles facing the development of ultra-clean car engines is the need for permanent-magnet electric motors to operate well at temperatures up to 200 degrees Celsius; Iowa researchers offer a way to create such magnets

  • Breakthrough: Acoustic cloak theoretically possible

    Invisibility cloak — deflecting microwaves around a cloaked object and restoring them on the other side, as if they had passed through empty space — has already been demonstrated; Duke researcher now shows that an acoustic cloak is theoretically feasible: Sound waves would travel seamlessly around the cloaked object and emerge on the other side without distortion; submarines could be hidden from sonar

  • Helmet sensors measure munition impact

    Worried about ever-more-powerful IEDs, the Army is providing soldiers from the 101st Airborne Division with helmets equipped with sensors which measure the energy wave generated by an “event” and the acceleration or jolt that follows

  • Accreditation program for labs which test body armor

    In the last three decades, the lives of more than 3,000 officers were saved by body armor; many, though, lost their lives or were injured when they were wearing ineffective body armor; NIST, Justice create program for accrediting labs which test and certify body armor

  • New London center to develop stronger ceramic materials

    Imperial College London launches Structural Ceramic Center; center will research and develop dramatically stronger and more durable structural ceramics made of inorganic materials such as oxides, carbides, and nitrides; new materials will be used in vehicle and body armor, reusable space craft, and pebble beds in nuclear reactors
