X-shaped radio galaxies might form more simply than expected

Posted by in categories: cosmology, physics

When astronomers use radio telescopes to gaze into the night sky, they typically see elliptical-shaped galaxies, with twin jets blasting from either side of their central supermassive black hole. But every once in a while—less than 10% of the time—astronomers might spot something special and rare: An X-shaped radio galaxy, with four jets extending far into space.

Although these mysterious X-shaped radio galaxies have confounded astrophysicists for two decades, a new Northwestern University study sheds new insight into how they form—and its surprisingly simple. The study also found that X-shaped radio galaxies might be more common than previously thought.

FTC Sues Data Broker Over Selling Location Data for Hundreds of Millions of Phones

Posted by in category: mobile phones

The U.S. Federal Trade Commission (FTC) on Monday said it filed a lawsuit against Kochava, a location data broker, for collecting and selling precise geolocation data gathered from consumers’ mobile devices.

The complaint alleges that the U.S. company amasses a “wealth of information” about users by purchasing data from other data brokers to sell to its own clients.

“Kochava then sells customized data feeds to its clients to, among other purposes, assist in advertising and analyzing foot traffic at stores or other locations,” the FTC said. “Among other categories, Kochava sells timestamped latitude and longitude coordinates showing the location of mobile devices.”

Drones are reshaping how rice is farmed in Vietnam

Posted by in categories: drones, food, sustainability

Vietnam is the world’s second-largest rice exporter, and XAG says its agricultural drones have become the “new favorite” of farmers that grow the crop.

Lê Thành Nguyên, at 62 years old, is one of the early adopters of agricultural drones in Vietnam. This year, he used drones on his seven-hectare rice farm for crop spraying, fertilization, and direct seeding by ordering the service from a local pilot team.
