Farming Equipment is Beaming Back ‘Reams of Data’ To its Manufacturers
Farming equipment like combine harvesters “beam back reams of data to its manufacturer,” reports Forbes:
GPS records the combine’s precise path through the field as it moves. Sensors tally the number of crops gathered per acre and the spacing between them. On a sister machine called a planter, algorithms adjust the distribution of seeds based on which parts of the soil have…

An Underwater Navigation System Powered by Sound
GPS isn’t waterproof. The navigation system depends on radio waves, which break down rapidly in liquids, including seawater. To track undersea objects like drones or whales, researchers rely on acoustic signaling. But devices that generate and send sound usually require batteries — bulky, short-lived batteries that need regular changing. Could we do without them? From a report: MIT researchers think so….
