DJI drones to come with plane detection

DJI drones to come with plane detection

Technology
Drone-maker DJI has pledged to add plane and helicopter "detection" features to its consumer drones, to reduce the risk of collisions.Some of DJI's industry-focused drones already have the feature built in but it has now pledged to add it to all drones weighing more than 250g (9oz).Its AirSense system picks up location signals broadcast by other aircraft.The drone pilot will then be warned that a plane or helicopter is nearby so they can take any necessary action.Visual sightingAirSense uses an existing technology called automatic dependent surveillance-broadcast (ADS-B).Aircraft transmitting ADS-B signals send out their satellite location data, altitude and other positioning information.ADS-B receivers can pick up these signals, allowing them to track an...

Gravitational wave hunters bag fourth black-hole detection

Science
Scientists have detected another burst of gravitational waves coming from the merger of two black holes.The collision occurred nearly 2 billion years ago, but it was so far away that its shockwave has only just reached us.This is the fourth confirmed detection made by an international team investigating Einstein's Theory of General Relativity.Sheila Rowan of Glasgow University, UK, said the team was now on the threshold of a new understanding of black holes."It is tantalising to see this new story of how black holes formed and evolved through history of the cosmos," she told BBC News."This information is almost within our grasp but we are not quite there yet."Media playback is unsupported on your deviceGravitational waves are ripples in space and time caused by cataclysmic events in the Un...
