German high-tech sector holds up
Turnover in German-made IT, telecommunications, and digital consumer electronics will hold steady at about €145 billion — still, the German high-tech industry would perform worse than the global high-tech sector as a whole, which is expected to boost sales about 3 percent to €2.416 trillion

NASA working on sonic boom-less jets
Sonic booms are one of the major downsides of supersonic jets; they may not matter much over the battlefield, but are a hindrance in civilian aviation — the noise was sufficient to restrict the Mach-2 Concorde to subsonic speeds when over land

Northrop Grumman unveils the X-47B
The large UAV — it has a 62-ft. wingspan and weighs around 45,000 pounds at takeoff — is the U.S. military’s principal vanguard for a potential new age of stealthy, autonomous combat aircraft

High-powered laser for refueling aircraft
Moving military units from theater to theater is a challenge for the military’s lift capabilities; an integral part of such capabilities is the ability to refuel aircraft in mid-flight, which is dangerous; researchers offer a way to use laser to recharge the plane’s batteries; for now the system is limited to surveillance UAVs, but the developers envision it being used for larger planes

Making older buildings safer during earthquakes
Buildings being built now in earthquake-prone regions are designed better to withstand tremors; trouble is, for a long while yet, most of the buildings in which people live and work were built before new earthquake-related design concepts and new materials were available; UC San Diego researchers look for ways to make these buildings safer

A simpler route to invisibility
Two years ago Duke University researchers built an invisibility cloak — a device that can make objects vanish from sight, at least when viewed using a narrow band of microwave frequencies; researchers now show how to create cloaks that work across a wider range of frequencies

Flexible, flapping flying machines may be on the horizon
Rigid wings and rotors have made aircraft very successful; nature, however, prefers flexible, flapping flying structures — just look at birds; indeed, the most efficient and acrobatic airfoils in nature are the flexible wings of the bat; Brown University researchers want to adopt the bat’s approach to flying for human use
