It’s Time to Talk About Robot Gender Stereotypes Oct 03, 2018

Show notes

Robots are the most powerful blank slate humans have ever created. Want a helpful robot? No problem. Want a mean one? Sure, if that’s what you’re into. A robot is a mirror held up not just to its creator, but to our whole species: What we make of the machine reflects what we are. That also means we have the very real opportunity to screw up robots by infusing them with exaggerated, overly simplified gender stereotypes. So maybe robots aren’t simply a mirror.

Crawling Dead: How Ants Turn Into Zombies Oct 03, 2018

Show notes

David Hughes leans back in his office in a standard-issue professorship chair as Penn State students in a plaza behind him shuffle toward classes. Between us on his desk—on either side of a paper cup of black coffee—are two trays of dead ants stuck through with pins. Some cling to leaves, others curl up around sticks, frozen in their tiny death postures like the now-fossilized humans who couldn’t escape Pompeii. All, though, have strange structures erupting out of their corpses.

Farmers Can Now Buy Designer Microbes to Replace Fertilizer Oct 02, 2018

Show notes

Jake Misch’s family has been growing corn in the sandy soils of northwestern Indiana for four generations. Like other farmers in the area, the Misches spray their fields with a nitrogen-rich fertilizer once in the spring when the seeds are planted, and once later in the year, when the corn is going through its growth spurt.

The Science Is Clear: Dirty Farm Water Is Making Us Sick Oct 02, 2018

Show notes

This story originally appeared on Reveal and is part of the Climate Desk collaboration. William Whitt suffered violent diarrhea for days. But once he began vomiting blood, he knew it was time to rush to the hospital. His body swelled up so much that his wife thought he looked like the Michelin Man, and on the inside, his intestines were inflamed and bleeding. For four days last spring, doctors struggled to control the infection that was ravaging Whitt, a father of three in western Idaho.

Trump's Auto Emissions Plan Is Full of Faulty Logic Oct 01, 2018

Show notes

There was a time many years ago when cars guzzled gas like beer, teenagers raced them on Friday nights, and Detroit automakers boasted about their vehicles' ever-increasing horsepower and speed. Since then, cars have become safer, cleaner and more efficient, mostly as a result of tougher standards from Washington.

San Francisco's Dream of 'Zero Waste' Lands in the Dumpster Oct 01, 2018

Show notes

In 2003, San Francisco set the lofty objective of getting to zero waste by 2020. By that timeline, the city should soon be performing a ceremonial burial for the last pair of broken headphones and closing down its moldering landfills. But with the deadline approaching, the city has sent that goal itself to the garbage heap. Earlier this month, as part of the Global Climate Action Summit, Mayor London Breed released a statement announcing new trash targets for 2030.

Darpa Goes Underground for Its Most Daring Robot Extravaganza Yet Sep 28, 2018

Show notes

On Thursday, Darpa gathered roboticists in the Louisville Mega Cavern, in Kentucky, and gave them a mission: Design robots to navigate a grueling subterranean course of tunnels and caves, some of the most unforgiving environments on Earth. They’re calling it the Subterranean Challenge, but you may as well call it the Death to All Robots Challenge. This event, which will begin next year, is a fundamentally different Darpa beast than the Darpa beasts that came before it.

Robot Lawnmowers Are Killing Hedgehogs Sep 28, 2018

Show notes

While Americans still wrangle their overgrown lawns by pushing or riding a lawnmower, many Europeans have handed off that responsibility to robots. These beefy, Roomba-like mowers loop their way around a yard, keeping grass trim and neat. To many of their users, the bots are endearing. Their owners give them names or cover them in decals of ladybugs or bumblebees. But the sentimentality only goes so far, because these blades-on-wheels have also been slicing up something other than grass: hedgehogs.

Cats Bad at Nabbing Rats But Feast on Other Beasts Sep 27, 2018

Show notes

In the summer of 2017, Michael Parsons found the urban rat haven of his dreams: A Waste Management transfer station—aka a literal trash heap, aka rat paradise—in Brooklyn, New York. For nearly two years, the behavioral ecologist and visiting scholar at Fordham University had been searching for a place to observe the city-dwelling rodents in their natural habitat. Trouble was, he needed to not only capture the critters and tag them, but then to set them free.

Everyone Wants to Go to the Moon Again—Logic Be Damned Sep 27, 2018

Show notes

The Moon is a pretty barren place. Sure, there are a few buggies, some golf balls, a flag, urine bags, a family photo. But it’s mostly empty. If a company called ispace has its way, though, Earth’s closest space neighbor will soon(ish) be the site of a bustling, industrial city full of workers and tourists. Moon Valley, the dreamers call it.
