In the August issue of the IEEE Spectrum magazine, read about the hunt for rogue planets, EV motors built without rare earth elements, how Shipt's drivers audited the algorithm that set their pay, and more!
The Hunt For Rogue Planets: The Race to Track Down Our Galaxy's Hidden Worlds
 |
“In 2020, an international group of astronomers reported a peculiar flicker of light originating from halfway across our galaxy. The signal was subtle; It caused a single star to brighten and dim, just once. But the implication of that little flicker was huge: It was the first credible sighting of an Earth-size rogue planet, a world untethered, floating freely between the stars…” |
DIY Cat Detector
 |
“Feral cats respond to humans differently than socialized pet cats do. They see us as threats rather than bumbling servants. So I wanted a way to find out if a shelter was occupied before I popped open its lid for maintenance. And that’s where radar comes in…” |
An EV Motor Without Rare Earths?
 |
“Global efforts to combat climate change hinge on pivoting sharply away from fossil fuels. To do that will require electrifying transportation, primarily by shifting from vehicles with combustion engines to ones with electric drive trains…” |
Workers vs. the Algorithm
 |
“In early 2020, gig workers for the app-based delivery company Shipt noticed their paychecks had become…unpredictable. Previously, they’d known what to expect from their pay because Shipt had a formula, which allowed workers to look at order amounts and choose jobs that were worth their time. But Shipt had changed the payment rules without alerting workers…” |
