Walking near the end of a massive tongue of glacial ice rising hundreds of meters above the sea, a group of scientists spotted an unexpected and ominous sign. About 100 meters from the edge of the glacier was a crack a few meters wide. The crack was fresh—there was no sign of it the day before. “We decided we wouldn’t walk farther,” said Guillaume Jouvet, a glaciologist at ETH Zurich in Switzerland. Continue reading
Whereas we can see hurricanes and blizzards coming from miles away, tornadoes form very quickly and on smaller scales. Predicting them requires very detailed understanding of atmospheric processes at a resolution that you can’t get with weather radar. Continue reading
NASA has awarded Black Swift Technologies, a specialized engineering firm, a contract to develop and deliver a purpose-built scientific platform to explore volcanoes in order to improve air traffic management systems and the accuracy of ashfall measurements. Continue reading
Uber has unveiled plans to partner with plane manufacturers to develop and test a network of flying cars by 2020. The ride-sharing company said it will run trials in the US city of Dallas and Dubai in the United Arab Emirates. Continue reading
Bat-detecting drones could help us find out what the animals get up to when flying. Ultrasonic detectors on drones in the air and on the water are listening in on bat calls, in the hope of discovering more about the mammals’ lives beyond the reach of ground-based monitoring devices.

Aerial dogfighting began more than a century ago in the skies over Europe with propeller-driven fighter aircraft carried aloft on wings of fabric and wood. An event held recently in southern California could mark the beginning of a new chapter in this form of aerial combat.
Modified UAV with actuators enabling rotor tilt.
Investigators at the Institute of Systems Optimization (ITE) at the Karlsruhe Institute of Technology (KIT) in Germany have undertaken a project to increase the level of control of quadrotor drones by adding tilt-able rotors and associated control systems.
Investigators at the Institute of Systems Optimization (ITE) at the Karlsruhe Institute of Technology (KIT) in Germany have been working on a promising approach that does not use GNSS.
