Thales' new friend-foe identification system for French frigates uses flat fixed-array active antenna technology instead of a conventional rotating antenna system. The TSA6000 has 360-degree electronic scanning capability and does not have mechanical or rotating parts.
With e-commerce projected to reach $4.5 trillion worldwide by next year, cybercriminals will respond with all the tools at their disposal, including phishing attacks and e-skimmers, which steal personal information from websites. David Lukic of IDstrong.com has a checklist for how buyers and sellers should handle cybersecurity and eventual data breaches.
Researchers are only able to periodically visit rainforests and other remote areas for monitoring, but now a very slow robot offers a way to provide continuous data. Georgia Tech roboticist Magnus Egerstedt was inspired by the seemingly poorly adapted sloth to develop his robot, which moves in the forest canopy only as necessary to capture sunlight for power as it uses its sensors to track factors such as air quality, temperature and insect and animal activity.
Flexible hydraulic hoses used in situations where steel tubing isn't an option can pose hazards if safeguards are not in place. Alan Hitchcox explores six ways to ensure hose safety, beginning with the use of protective sleeves where repeated contact with machinery and movement present an elevated risk of failure.
A Lake Michigan bluff has been fortified, but not enough to keep a historic pavilion safe at Orchard Beach State Park, so plans have been made to move the structure in December. The 80-year-old, 400-ton limestone and timber structure will be transported to the park's safer day-use area.

Los Angeles' stormwater system is failing to capture stormwater as a valuable resource before it becomes polluted, and the new draft MS4 permit reveals no effort to address the problem, writes Corinne Bell. Dozens of groups have stepped forward already to call for more protective measures, and more public comment is being sought through Dec. 7.
Australia's popular Byron Bay beach has been severely affected by erosion, although emergency dune-stabilization is underway. Recent sand erosion has been the worst in many years, and locals have requested more help from the state government.
