Yes, You Do Walk Weird When You're Texting, Scientists Confirm

Texting while walking changes more than just your chances of running into a pole or another pedestrian. It alters your gait, according to a new study spotted by CNET.

In a recent study published in PLOS One, scientists from Anglia Ruskin University in the UK recruited 21 young people to text and walk under observation. The participants promenaded along an 18-foot-long walkway that contained a fiberboard a few inches high and a step-up box (like you'd find at a gym) designed to trip them up. They navigated the walkway 12 times each: without their phone, while talking on their phone, while reading a text, and while writing and sending a text.

When people whipped out their phones, they took a lot longer to traverse the walking path, which is no doubt a good thing. Compared to not having a phone at all, people took 118 percent longer to complete the task while writing a text. Navigating the walkway while reading a text took 67 percent longer than when there was no phone present, and talking on the phone took 83 percent longer.

The decreased visibility and attention clearly made people more cautious, and that changed their gaits significantly. "We found that using a phone means we look less frequently, and for less time, at the ground, but we adapt our visual search behavior and our style of walking so we're able to negotiate static obstacles in a safe manner," study co-author Matthew Timmis said in a university press release. "This results in phone users adopting a slow and exaggerated stepping action."

None of the participants tripped, and if anything, this study shows that distracted walkers are a little more careful than we give them credit for. They were able to successfully navigate the obstacles while not looking directly at them, a win for peripheral vision. Texting lanes have popped up in a few cities around the world (though mostly as a joke), and in one German city, there are ground-level traffic lights designed to keep texters safe in crosswalks.

Whether or not you think texting while walking is a problem, though, depends on who's doing it. A 2015 survey found that 74 percent of respondents believed "other people" had a problem with distracted walking, but only 29 admitted to doing it themselves. Meanwhile, reports of texting-while-walking accidents may be overblown, since there aren't official statistics on cell-phone-involved pedestrian crashes. The fact of the matter is, it's dangerous to be a pedestrian in the U.S., phone or no phone, largely due to road design rather than iPhone availability. (Sweden, where people also use cell phones, saw its lowest annual road deaths since World War II in 2016, and for the past three years in a row, fewer than 270 people have died on Swedish roads per year.)

Putting your phone down while you're walking down the street might have value beyond personal safety, though. As part of its digital detox program, the technology podcast Note to Self challenges people to put away their phone whenever they're in motion. It's supposed to help wean you off your dependency on your phone, but it could have the added benefit of making you look much more suave when sauntering down the street.

Fish Tube: How the 'Salmon Cannon' Works and Why It's Important

If you’ve been on the internet at any point in the past week, you’ve certainly come across footage of wildlife conservationists stuffing salmon into a giant plastic tube and shuttling them over obstacles. It’s so bizarre—even by the already loose standards of the web—that it briefly ignited discussions over fish welfare, its purpose, and the seeming desire of people to be similarly transported through a pneumatic tunnel into a new life.

Naturally, the “salmon cannon” has a mission beyond amusing the internet. The system was created by Whooshh Innovations, a company that essentially adopted the same kind of transportation system featuring pressurized tubing that's used in banking. Initially, the system was intended to transport fruit over long distances without bruising. At some point, engineers figured they could do the same for fish.

The fish payload is secured at the entrance of the tube—acceptable species can weigh up to 34 pounds—and moves through a smooth, soft plastic tube that conforms to their body shape. Air pressure behind them keeps them moving. The fish are jettisoned between 16 and 26 feet per second to a new location, where they emerge relatively unscathed. Because there’s no need for a water column, the tubing can cover most terrain at virtually any height.

The tubing solution is a human answer to a human problem: dams. With fish largely confined to still bodies of water thanks to dams and facing obstacles swimming upstream to migrate and spawn, fish need some kind of assistance. In the past, “fish ladders” have helped fish move upstream by providing ascending steps they can flop on, but not all fish can navigate such terrain. Another system, trapping and hauling fish like cargo, results in disoriented fish who can even forget how to swim. The Whooshh system, which has been in used in Washington state for at least five years, allows for expedient fish export with an injury rate as little as 3 percent, although study results have varied.

The video features manual insertion of the fish. In the wild, Whooshh counts on fish making semi-voluntary entries into the tubing. Once they swim into an enclosure, they’re curious enough about the tube to go inside.

If all goes well, the system could help salmon be reintroduced to the Upper Columbia River in Washington, where the population has been depleted by dams. Testing of the device there is awaiting approval from the U.S. Army Corps of Engineers.

12 Facts About Netflix, Recommended For You

Netflix has become the world’s intravenous line for filmed entertainment. And like any media empire, it has a few stories of its own to tell. Take a look at some lesser-known, non-buffering facts about the streaming giant.

1. Early Netflix subscribers got a lot of Chinese pornography.

In 1998, Netflix was still in the business of selling as well as renting DVDs. To try and offer consumers something new, co-founder Marc Randolph decided to offer footage of President Bill Clinton’s Grand Jury testimony about his involvement with Monica Lewinsky. But according to the book Netflixed, the duplicating house had a mix-up: out of the 1000 customers who ordered Clinton's interview, a few hundred received discs full of hardcore Chinese pornography.

2. Netflix was originally called Kibble.

Choosing a name for the company was a drawn-out process. Directpix.com, Replay.com, and other names were considered; so was Luna.com, which was the name of Randolph’s dog. When the company was being incorporated, he named it Kibble.com until they could decide on something permanent.

3. Netflix executives used to make house calls.

From the beginning, Netflix has been preoccupied with seeing how users interact with its software in order to select titles. In the late 1990s, subscribers near the company’s location in Los Gatos, California were reached via telephone and asked a series of questions. Then staffers would ask if they could stop by to watch them use the site. Surprisingly, most agreed. Netflix brought them coffee, a small investment for gaining valuable information about their usage.

4. Netflix got Dennis Quaid to sing.

For a 2006-2007 publicity tour, Netflix decided to screen films in thematically-correct locations: For example, Field of Dreams was shown in the “real” Iowa cornfield-slash-baseball diamond featured in the movie. But the company also wanted actors to make appearances. Their approach: offer to let those with bands perform for the crowds. Kevin Costner, Bruce Willis, Dennis Quaid, and Kevin Bacon all agreed to the barter deal. Quaid and his band, The Sharks, played in New Orleans before a screening of his film The Big Easy.

5. Netflix has made a science out of spoilers.

Because so much of Netflix’s high-profile content can be “binged” in a single weekend, the company commissioned cultural anthropologist Grant McCracken to examine how spoilers affect a person’s viewing habits. McCracken identified classifications of spoiler-prone people by whether they ruin a plot twist intentionally or hold it over others. (Some people are “Coded Spoilers,” too self-aware to let anything slip. These people are your friends.) His verdict? Some people enjoy the power they get from having knowledge of spoilers. But if a show is good enough, knowing about key scenes won't dissuade viewers from watching.

6. Netflix staffers think you decide on a movie in two minutes.

Netflix spends more than $150 million on improving their recommendation system every year, trying to arrange selections based on what they think you might like. That kind of personalized menu is necessary: The company estimates that users spend only two minutes browsing for a title before choosing one or opting for another diversion entirely.

7. Netflix staffers also think you might be kind of a liar. 

You can stop trying to impress Netflix with the streaming version of keeping Ulysses on your coffee table. In a 2013 WIRED interview, Carlos Gomez-Uribe—the company's vice president of product innovation from 2010 to 2016—noted that viewers often report viewing documentaries or esoteric foreign movies. “But in practice,” he said, “that doesn’t happen very much.”

8. the first "netflix original" was an abstract test footage short.

In order to test frame rates and how their streaming service handles different kinds of content, Netflix produced 11 minutes of test footage in 2011 that can be viewed by typing “example show” in their search engine. Cut together (as seen above), the shorts become a very strange, very abstract art film, with an unidentified man juggling and reciting Shakespeare. (But not, sadly, juggling while reciting Shakespeare.)

9. Netflix binge-watching might correlate with depression. 

A 2015 study by the University of Texas found that respondents who claimed to binge Netflix shows were more likely to suffer from depression, lack of self-control, or loneliness. The good news? The sample group was small—only 316 people—and the university’s definition of “binge-watching” was as low as two episodes. Amateurs. 

10. There’s a secret Netflix menu.

No, not that kind of secret menu. Pressing Shift + Alt + a left mouse click brings up a troubleshooting menu that allows you to adjust the bit rate of a stream so it doesn’t buffer. (On a Mac, it's Shift + Option + click.) The picture quality won’t be as good, but it’s better than a pixelated Demogorgon.

11. There was once a glitch in the Netflix matrix. 

In 2014, Netflix’s content descriptions became odd amalgamations of two different titles to create one completely nonsensical listing. The summaries were quickly fixed, but not before someone took several screen shots of the mishaps.

12. You'll soon be able to stream Netflix in a Tesla.

In July 2019, Tesla founder Elon Musk informed Tesla owners they would soon be able to stream both Netflix and YouTube in their cars, an attractive option for anyone looking to keep passengers occupied. But there's a catch: The services only work when the cars are parked. The feature will be available in newer-model cars at a date to be determined.
