Nature inspires advances in ultrasound technology
Sonar and ultrasound, which use sound as a navigational device and to paint accurate pictures of an environment, are the basis of many technologies, including medical ultrasound machines and submarine navigation systems; when it comes to more accurate sonar and ultrasound, however, animals’ “biosonar” capabilities still have the human race beat – but not for long

Flight control software helps pilots stick carrier landings
Navy and Marine Corps aviators conducting carrier landings today line up with a moving flight deck in a complicated process; they must constantly adjust their speed and manipulate the aircraft’s flight control surfaces — ailerons, rudders, and elevators — to maintain the proper glide path and alignment to the flight deck for an arrested landing; new software makes landing much easier

The long view
Is the Fear of Cyberwar Worse Than Cyberwar Itself?
Unrealistic cyberwar expectations could hold the insurance industry back, and that’s the real economic security problem. The “hyperbolic characterization of cyberwar is likely a bigger problem than the threat of cyberwar itself. The problem is one of economic security,” Tom Johansmeyer writes.
Outsourcing Surveillance: A Cost-Effective Strategy to Maintain Maritime Supremacy
Persistent surveillance is one of the most valuable types of surveillance missions. But, Josh Portzer and Aaron Stein write, “Persistent surveillance is a challenging problem for two reasons: capacity and cost. In today’s budgetary climate, “simply increasing U.S. military capacity is not tenable. [But] by increasing the number of sensors globally, the Department of Defense would not only gain valuable, near-persistent surveillance data in areas of interest at (relatively) affordable prices, but also would enjoy the option of gray-zone operations given the strategic ambiguity that outsourcing provides.”
How Do Civilians Respond to Political Violence?
When conflict breaks out, civilians inevitably suffer. But they do not react uniformly, with some fleeing, others staying, and still others joining the fray. Civilians’ perceptions of their own agency often shape their behavior. Aidan Milliff writes that this understanding has implications for policy: The United States and other countries, in their efforts to help civilians who face political violence, should focus more on changing these civilians’ perceptions.
