“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. Now they’re starting to show up someplace even a little more personal: the doctor’s office. Learn about your ad choices: dovetail.prx.org/ad-choices...

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.

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.

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 about your ad choic...

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 about your ad choices: dovetail.prx.org/ad-choices

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.

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.

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.

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 about your ad choices: dovetail.prx.org...

In December 1861, as a California drought was wearing into its fifth year, farmers on the West Coast were all asking for one thing for Christmas: rain. And boy did they get it. For 43 days rain and snow fell across the state, causing rivers to surge their banks, turning the 300-mile long, 20-mile-wide Central Valley into an ice-cold inland sea. LA got 66 inches. So deep were Sacramento’s floodwaters that the capital had to be relocated to San Francisco. Learn about your ad choices: dovetail.prx....

If humans ever leave this solar system, they probably won't do it aimlessly. More likely they'll set a course for some distant waypoint, perhaps another solar system, to visit, study, or maybe even settle. And when they do, there's a good chance the destination they choose will have been discovered by NASA's new planet-hunting spacecraft. Called the Transiting Exoplanet Survey Satellite, the instrument will soon hitch a ride to space aboard one of SpaceX's Falcon 9 rockets. Learn about your ad c...

In 2007, I spent the summer before my junior year of college removing little bits of brain from rats, growing them in tiny plastic dishes, and poring over the neurons in each one. For three months, I spent three or four hours a day, five or six days a week, in a small room, peering through a microscope and snapping photos of the brain cells. The room was pitch black, save for the green glow emitted by the neurons. Learn about your ad choices: dovetail.prx.org/ad-choices...

Twenty-seven years ago, a group of physicists made an accidental discovery that flipped mathematics on its head. The physicists were trying to work out the details of string theory when they observed a strange correspondence: Numbers emerging from one kind of geometric world matched exactly with very different kinds of numbers from a very different kind of geometric world. To physicists, the correspondence was interesting. To mathematicians, it was preposterous. Learn about your ad choices: dove...
