A Bug-Like Robot Uses Electricity to Walk Upside Down Dec 20, 2018

Show notes

A bug’s life doesn’t seem half bad, if you can overlook the super-short lifespan or the threat of getting eaten by lizards or swatted at by humans. Flying is nice, as is being able to walk on ceilings. The versatility is enviable, which is why roboticists are on a quest to imbue machines with the power of the bug. But to harness the powers of nature, roboticists are resorting to very un-biological means.

Dark Matter Hunters Pivot After Years of Failed Searches Dec 19, 2018

Show notes

Physicists are remarkably frank: they don’t know what dark matter is made of. “We’re all scratching our heads,” says physicist Reina Maruyama of Yale University. “The gut feeling is that 80 percent of it is one thing, and 20 percent of it is something else,” says physicist Gray Rybka of the University of Washington. Why does he think this? It’s not because of science. “It’s a folk wisdom,” he says.

Can't Remember What You Read? Blame Font, Not Forgetfulness Dec 19, 2018

Show notes

Remember all those classics you devoured in comp-lit class? Neither do we. Research shows that we retain an embarrassingly small sliver of what we read. In an effort to help college students boost that percentage, a team made up of a designer, a psychologist, and a behavioral economist at Australia’s RMIT University recently introduced a new typeface, Sans Forgetica, that uses clever tricks to lodge information in your brain.

Scientists Journey Into the Dark Side of Cannabis Dec 18, 2018

Show notes

Cannabis is a hell of a drug. It can treat inflammation, pain, nausea, and anxiety, just to name a few ailments. But like any drug, cannabis comes with risks, chief among them something called cannabis use disorder, or CUD. Studies show that an estimated 9 percent of cannabis users will develop a dependence on the drug.

A 'Roadless Trip' in a 3D-Printed, Solar-Powered Snow Rover Dec 18, 2018

Show notes

Antarctica is the driest, highest, windiest, and, of course, coldest continent. Since it’s nearly uninhabitable for humans, it’s also the cleanest. That makes it the perfect place to launch an odyssey aimed at persuading people to curb their plastic-pitching habits.

Embrace a Fake Meat Future for Its Lesser-Known Benefits Dec 17, 2018

Show notes

Recently I rolled into a local restaurant to try an Impossible Burger, an all-plant patty invented by the Silicon Valley startup Impossible Foods. It’s renowned for having an eerily chewy, even bloody, meatlike quality, a startling verisimilitude that has made it “perhaps the country’s most famous burger,” as New York magazine recently wrote. One bite into its gorgeous, smoky flavor and, damn, I was convinced.

No GPS? A DIY Radio Transmitter Can Help You Navigate Dec 17, 2018

Show notes

Suppose you traveled back in time—say 40,000 years into the past—and then you got stuck. What would you do? How would you rebuild all the stuff that you like? That's the premise of the book How to Invent Everything: A Survival Guide for the Stranded Time Traveler, by Ryan North. Without getting into the nitty-gritty details, it gives you the general idea of how things like an electric motor or wifi work.

Sci-Fi Promised Us Home Robots. So Where Are They? Dec 14, 2018

Show notes

Science fiction has promised us a whole lot of technology that it’s rudely failed to deliver—jetpacks, flying cars, teleportation. The most useful one might be the robot companion, à la Rosie from The Jetsons, a machine that watches over the home. It seemed like 2018 was going to be the year when robots made a big leap in that direction.

A Designer Seed Company Is Building a Farming Panopticon Dec 14, 2018

Show notes

When Geoffrey von Maltzahn was first pitching farmers to try out his startup’s special seeds, he sometimes told them, half-acknowledging his own hyperbole, that “if we’re right, you shouldn’t just see results in the field, you should be able to see them from outer space.” As the co-founder of a company called Indigo Ag, von Maltzahn was hawking a probiotic that he hoped would increase their crop yields dramatically.

Even Zoos Are Learning the Art of Doomsday Prepping Dec 13, 2018

Show notes

When smoke from California’s wildfires was smothering the Bay Area last month, the Oakland Zoo closed to the public. The staff worked in shifts, many of them wearing N95 face masks, monitoring how animals dealt with the smoke from the fires more than a hundred miles away. Southern California was also dealing with wildfires and heavy smoke. In both regions, zoos had to make some tough decisions.
