How Google’s Earthquake Alerts Protected Millions — And How to Turn It On in Quake-Prone Countries When two massive earthquakes (7.2 and 7.5) struck Venezuela recently, the country had no national early warning system. But millions of Android phones lit up with loud alerts seconds to minutes before the shaking hit — giving people precious time to drop, cover, and hold on. Google’s clever system turns the accelerometers in over 2 billion Android phones into a giant crowdsourced seismic network. It detects the first waves, confirms the quake, and blasts notifications to users in the affected area. In Venezuela, it reached 11.4 million people — proving technology can save lives even where governments can’t. How to activate it (works in nearly 100 countries): Open Settings on your Android phone. Tap Safety & Emergency (or search for “Earthquake alerts”). Select Earthquake Alerts and toggle it ON. Keep Location services ena...

The drone, which made its debut at the Dubai Airshow earlier this month, looks nothing like your average 3D-printed toy plane. It has a 9-foot-long (3 meters) wingspan and an aerodynamic design that gives it a futuristic appearance. But about 80 percent of the sleek, unmanned aerial vehicle (UAV) is designed and manufactured using 3D printing methods, according to Aurora Flight Sciences and Stratasys, the companies that developed the drone. The UAV weighs just 33 lbs. (15 kilograms) and can fly at speeds exceeding 150 mph (241 km/h). [ The 10 Weirdest Things Created by 3D Printing ] "To the best of our knowledge, this is the largest, fastest and most complex 3D-printed UAV ever produced," Dan Campbell, aerospace research engineer at Aurora Flight ...
