An Anti-Aging Pundit Solves a Decades-Old Math Problem

Science, Spoken ·

2018/05/08

In 1950 Edward Nelson, then a student at the University of Chicago, asked the kind of deceptively simple question that can give mathematicians fits for decades. Imagine, he said, a graph—a collection of points connected by lines. Ensure that all of the lines are exactly the same length, and that everything lies on the plane. Now color all the points, ensuring that no two connected points have the same color. Learn more about your ad choices. Visit megaphone.fm/adchoices

2018/05/07

It’s spring and privacy concerns are in the air. Between the recent revelations that Facebook let Cambridge Analytica capture data from 87 million of its users to be improperly used to influence the US presidential election, and news that California investigators cracked the long-cold case of the Golden State Killer by running a genetic profile collected from crime scene DNA through a public genealogy website, people are feeling a bit...spooked.

Science, Spoken ·

2018/05/07

How it used to go was, after some extreme weather event, reporters would ask Climate McScientist, PhD whether the flood/drought/hurricane/disease outbreak/wildfire/superstorm happened because of climate change. Dr. McScientist would pat the reporter on the head and say: Well, of course, one can never ascribe any single weather event to a changing global climate. Learn more about your ad choices.

The Physics of Leia Using the Force

Science, Spoken ·

2018/05/04

Now that Star Wars: The Last Jedi is out on DVD (and digitally), I think it's safe to discuss one very interesting scene in the spirit of May the Fourth. However, there is a chance you haven't seen it—so this is your spoiler alert. In this scene, Leia's ship is attacked by the First Order. The attack knocks a hole in the bridge, which causes the air inside to push out most of the crew in that area—including Leia. So there she is ... just floating away from the spaceship.

2018/05/04

For the dozen years between 1974 and 1986, he rained down terror across the state of California. He went by many names: the East Side Rapist, the Visalia Ransacker, the Original Night Stalker, the Golden State Killer. And on Wednesday, law enforcement officials announced they think they finally have his real name: Joseph James DeAngelo. Police arrested the 72-year-old Tuesday; he’s accused of committing more than 50 rapes and 12 murders. Learn more about your ad choices. Visit

2018/05/03

For the first time since launching the Curiosity rover in 2011, NASA is sending a spacecraft to the surface of Mars. Exciting! Surface missions are sexy missions: Everyone loves roving robots and panoramic imagery of other worlds. But the agency's latest interplanetary emissary won't be doing any traveling (it's a lander, not a rover). And while it might snap some pictures of dreamy Martian vistas, it's not the surface that it's targeting. Learn more about your ad choices. Visit

When I ask Bradley Worthington to tell me about that one time people in the southwest thought his trucking company, McCollister's, was moving a UFO across the country, he laughs. There’s not a “that one time.” “It happens frequently,” he says, “especially with oversized things.” And McCollister's hauls a lot of oversized things. Learn more about your ad choices.

Insect-Borne Diseases Have Tripled. Here's Why.

Science, Spoken ·

2018/05/02

The year 2004 was a simpler time to be an infectious disease doctor in the US. Zika and chikungunya hadn’t yet emerged. Mystery RNA viruses weren’t spreading by tick bite around America’s heartland, killing farmers and ranchers. Certainly no one was on the lookout for a meat allergy caused by a tick with a white splotch on its back the shape of Texas. But that was then. Learn more about your ad choices.

2018/05/02

On a breezy evening this past weekend, I sat out on my patio, lit a sizable joint, and took little drags from it til the burn line singed my fingertips. When I stood up I was stoned, and I knew it; I rarely smoke pot, so when I do I really feel it. But how high was I, really? I reached for my phone, logged into an app called Druid, and took a five minute test. When I finished it gave me my results, which appeared in red: Your DRUID impairment score is 50.3.

Does Your Doctor Need a Voice Assistant?

Science, Spoken ·

2018/05/01

“Siri, where is the nearest Starbucks?” “Alexa, order me an Uber.” “Suki, let’s get Mr. Jones a two-week run of clarithromycin and schedule him back here for a follow-up in two weeks.” Doesn’t sound that crazy, does it? For years, voice assistants have been changing the way people shop, get around, and manage their home entertainment systems.

How a Soviet A-Bomb Test Launched US Climate Science

Science, Spoken ·

2018/05/01

This storyoriginally appeared on Undarkand is part of theClimate Deskcollaboration. On March 23, 1971, the Soviet Union set off three Hiroshima-scale nuclear blasts deep underground in a remote region some 1,000 miles east of Moscow, ripping a massive crater in the earth. The goal was to demonstrate that nuclear explosions could be used to dig a canal connecting two rivers, altering their direction and bringing water to dry areas for agriculture.

2018/04/30

The tsunami-driven seawater that engulfed Japan’s Fukushima Daiichi nuclear plant has long since receded. But plant officials are still struggling to cope with another dangerous flood: the enormous amounts of radioactive water the crippled facility generates each day. More than 1 million tons of radiation-laced water is already being kept on-site in an ever-expanding forest of hundreds of hulking steel tanks—and so far, there’s no plan to deal with them.

The Terrifying Technological Tactics Behind BattleBots

Science, Spoken ·

2018/04/30

It's hard not to like BattleBots. It is essentially a modern technology-based sporting event in which teams build remote controlled robot-like things that fight in an arena. Two robots enter, one robot leaves—and on May 11, the eighth season of the showdown begins. Of course, there are many engineering aspects of these bots—but underlying every bit of technological terror is some very fundamental physics. Let's go over some of the physics-based tactics used in the game. Learn more about your ad

The main act of Kang-Kuen Ni’s experiment could fit on the tip of a needle—and it happens in a fraction of a second. The Harvard chemist takes two individual atoms, a sodium and a cesium, each about 10,000 times smaller than a bacterium. Then, very carefully, she brings them together to become a single molecule: sodium cesium. It’s an unlikely pairing. Learn more about your ad choices. Visit megaphone.fm/adchoices

A New Startup Wants to Use Crispr to Diagnose Disease

Science, Spoken ·

2018/04/27

In 2011, biologists Jennifer Doudna and Emmanuelle Charpentier published a landmark paper introducing the world to Crispr. The arcane family of bacterial proteins had a talent for precisely snipping DNA, and one of them—Cas9—has since inspired a billion-dollar boom in biotech investment. Clinical trials using Cas9 clippers to fix genetic defects are just beginning, so it will be years before Crispr-based cures could potentially reach the world. Learn more about your ad choices.

The Lab Making Robots Walk Through Fire and Ride Segways

Benefits of robots: 1. They never get tired. 2. They can lift very heavy things. 3. They can walk through (controlled) conflagrations on college campuses. At least, that is, the robots in and around roboticist Jessy Grizzle’s lab at the University of Michigan. Specifically, Grizzle is working with a remote-controlled biped called Cassie, a research platform that roboticists are using to master bipedal locomotion. Learn more about your ad choices.

What Happens When Science Just Disappears?

2018/04/25

Kay Dickersin knew she was leaping to the front lines of scholarly publication when she joined The Online Journal of Current Clinical Trials. Scientific print-publishing was—and still is—slow and cumbersome, and reading its results sometimes required researchers to go to the library. But as associate editor at this electronic peer-reviewed journal—one of the very first, launched in the summer of 1992—Dickersin was poised to help bring scientists into the new digital age.

Delivery Bots Have Awkward Sidewalk Interactions, Too

Science, Spoken ·

2018/04/25

Self-driving cars have it rough. They have to detect the world around them in fine detail, learn to recognize signals, and avoid running over pets. But hey, at least they’ll spend most of their time dealing with other robot cars, not people. Now, a delivery robot, on the other hand, it roams sidewalks. That means interacting with people—lots of people—and dogs and trash and pigeons. Unlike a road, a sidewalk is nearly devoid of structure. It’s chaos. Learn more about your ad choices. Visit

Why Can't We Fix Puerto Rico's Power Grid?

2018/04/24

And then the lights went out. Again. The loss of electrical power in Puerto Rico and the US Virgin Islands after Hurricane Maria churned across the islands in September 2017 was already the second-biggest blackout in the history of power on Earth—3.4 billion lost customer-hours. But in recent weeks, various agencies were touting their success in restoring Puerto Rico’s flattened grid. Learn more about your ad choices. Visit megaphone.fm/adchoices
