A Robot's Life

Have you worked in a warehouse? How about a warehouse filled with Roomba-like robots that crawl the floor looking for stuff? In this three-minute presentation, Kiva Systems founder Mick Mountz explains how his company's robots work: the robot locates an item in the warehouse's "pod" system, fetches the pod containing the item (while avoiding other robots driving around), brings the pod to a "pick worker" (human), who hands the item off to a "packing worker" (also human), who puts the item (or collection of items) in a box for shipment. Periodically the robot is assigned a resting period, to recharge.

While I haven't worked in a warehouse, this seems like a distinct improvement over sending humans through the maze of items, locating and retrieving each one. Sure, the picking and packing are not exactly awesome jobs either, but at least this is a start. Have a look, and see how robots are taking at least one of the tedious steps out of warehouse fulfillment.

SpaceX's Landing Blooper Reel Shows That Even Rocket Scientists Make Mistakes

On March 30, 2017, SpaceX did something no space program had done before: They relaunched an orbital class rocket from Earth that had successfully achieved lift-off just a year earlier. It wasn't the first time Elon Musk's company broke new ground: In December 2015, it nailed the landing on a reusable rocket—the first time that had been done—and five months later landed a rocket on a droneship in the middle of the ocean, which was also unprecedented. These feats marked significant moments in the history of space travel, but they were just a few of the steps in the long, messy journey to achieve them. In SpaceX's new blooper reel, spotted by Ars Technica, you can see just some of the many failures the company has had along the way.

The video demonstrates that failure is an important part of the scientific process. Of course when the science you're working in deals with launching and landing rockets, failure can be a lot more dramatic than it is in a lab. SpaceX has filmed their rockets blowing up in the air, disintegrating in the ocean, and smashing against landing pads, often because of something small like a radar glitch or lack of propellant.

While explosions—or "rapid unscheduled disassemblies," as the video calls them—are never ideal, some are preferable to others. The Falcon 9 explosion that shook buildings for miles last year, for instance, ended up destroying the $200 million Facebook satellite onboard. But even costly hiccups such as that one are important to future successes. As Musk once said, "If things are not failing, you are not innovating enough."

One Day, You May Not Have to Take Your Laptop Out at the Airport

TSA security lines might be a little less annoying in the future. According to Condé Nast Traveler, the agency will soon test new airport scanners that allow you to keep your liquids and laptop in your carry-on bag during security screening, a benefit currently only available to those who have been accepted into the agency’s PreCheck program.

The ConneCT scanners have met the TSA's "advanced technology detection standards," according to the company that makes them, Analogic, meaning that they can be tested out at airports across the U.S.

Computed tomography scanning technology is regularly used in hospitals and research labs for everything from diagnosing cancer to studying mummies. The imaging technique uses x-rays that rotate around whatever object is being imaged to create 3D images that provide more detail than those created by the regular x-ray scanners currently used to inspect carry-on luggage.

The ConneCT scanners have been in the works for 10 years. The devices have x-ray cameras that spin around the conveyor belt that holds your bag, creating a 3D image of it. Then algorithms help flag whether there's something suspicious inside so that it can be pulled aside for further screening by hand. They've already been tested in airports in Phoenix and Boston, but haven't been used on a national level yet.

But don't expect to see the high-tech scanners at your local airport anytime soon. According to the TSA, they have to undergo yet more testing before any of the machines can be deployed, and there’s no timetable for that yet.

Until then, as you're packing your liquids, just remember—you can always just freeze them.
