Why Snap’s Spectacles Are Going to (Finally) Make Life Logging Cool

The human desire to log the realities of everyday life is something that technology companies have been trying to turn into a successful product for years. With a new pair of smart glasses on offer, the company behind Snapchat hopes that the answer lies in simplicity.

Some of the strongest proponents of the life-logging movement have recently retired from the pursuit. But those early adopters sought to record everything, from sleep and steps to calorie intake and mood. Ultimately, they found the process difficult and unrewarding.

Google’s attempt to capitalize on the phenomenon with its Glass project struggled to take off. First announced in April  2013, the device later became available as part of the Explorer Program for the princely sum of $1,500. It was ultimately scrapped as a commercial product last year, sidelined instead to research and workplace use.

Glass had many problems. Certainly, its price made it an exclusive item. Privacy advocates worried ceaselessly about people snapping images without permission, coining the fabulous term “Glasshole” along the way. But perhaps its biggest failing was Google’s attempt to shoehorn a small computer, display, camera, microphone, and more into a diminutive frame. This was Google trying to invent the future, and failing.

Now Snap—the new name of Snapchat—thinks it can do better.

Where Glass was an exercise in speculative future-gazing, Snap’s new Spectacles are a study in pragmatism. The new sunglasses, which are styled like Ray-Bans, allow the wearer to record first-person video at the press of a button, shooting up to 30 seconds of circular video with a 115-degree field of view. The clips can then be transferred to a smartphone via Wi-Fi or Bluetooth, to be added to Snapchat.

That’s it. Nothing else to it.

Their simplicity—the very decision not to even attempt to break new technological ground—could be the very thing that cements their place in the future. Perhaps their most compelling feature is that they have a clear and distinct purpose: you can wear them, acquire first-person images and video of what you have done, and then quickly upload that material to the Web.

Snap does give Spectacles one particularly innovative touch: the circular video that the device shoots. In a stroke, that’s solved—for Snapchat, at least—the annoying problem of video appearing in the wrong orientation if people hold their phone in landscape view.

At $130, the glasses are also easy on the wallet. Snap’s CEO, Evan Spiegel, referred to them as a “toy” in the Wall Street Journal interview in which they were announced, and he’s right. At that price, it’s a piece of hardware that can be purchased for good old-fashioned fun, or given to a teenager as a treat. Like any other toy, they’ll become their own advertising if they do sell well: while smartphones are inherently private devices, wearing a pair of Snap’s glasses alerts the world to what a person is doing, which may appeal to people looking to make a statement.

But that brings us to one of the major questions facing the device: who, exactly, is going to buy them?

The styling is undeniably youthful, and it’s easy enough to imagine a teenager lusting after a pair. But earlier this year, Snapchat’s vice president of content, Nick Bell, pointed out that two-thirds of its users are over 18, and 50 percent of new daily users are over 25. Those folks are more attractive to advertise to, because unlike teens, they tend to have money. But it’s not clear if Spectacles are the product to drive that adoption.

There’s also the pesky question of privacy. Glass suffered an onslaught of criticism for the ways in which it enabled snooping, and Snap will undoubtedly be seeking to avoid the same. It’s clearly at least considered the issue: the glasses light up when they’re recording, which may help. A little. But that feature is sure to be hacked within days of the device’s release.

What could act in Snap’s favor is volume. While Glass was the preserve of wealthy, middle-aged Silicon Valley types who were few and far between and easy to feel alienated by, cities awash with Spectacle-wearing Millennials could help normalize public video recording.

Not that will happen overnight. Spiegel told the Wall Street Journal that the company was “going to take a slow approach to rolling them out,” so that it can work through a process of “figuring out if it fits into people’s lives and seeing how they like it.” If it does, and they do, Spectacles could help Snap turn an idea that’s always proved unsuccessful into something that allows people to document their lives easily.

It could, perhaps, make life logging cool again.

Most of India Still Isn’t Online—Here’s Google’s Plan to Fix That

Google has made a series of announcements that make one thing very clear: it plans to take India’s Internet by storm.

The company is no stranger to working in India, with its railroad station Wi-Fi project already proving to be a notable success. But today it announced a series of new products and projects squarely aimed at the Indian market, signaling its intent to tap a market of 1.25 billion people where only 200 or 250 million are currently online.

Most notable among the announcements is a new YouTube app called Go, specially designed for users in developing countries with poor—and expensive—data connections. While the app does allow video downloads for later viewing, that’s not its real party trick. Instead, as Wired explains, it allows people to share video with others in their community using ad-hoc wireless networks, so users don’t have to chew through cellular data allowances. That feature was inspired by trips to India, where Google saw people sharing videos not as links, but via SD cards that were passed around.

In partnership with Google, Indian Railways’ RailTel offers free Wi-Fi Internet service in Mumbai’s central railway station. The service is due to be rolled out in 100 of the country’s busiest stations by the end of 2016.

The app isn’t the only data-saving scheme Google’s been working on. It’s also announced that Chrome for Android will now provide a Data Saver mode that will allow it to more aggressively compress audio and video, as well as downloading a specially streamlined version of Web pages. It’s claimed that MP4 files can be streamed using 67 percent less data, while a Web page ends up just 10 percent of the size. There will also be the option to download Web pages for later viewing. Clearly, there will be a loss of quality—but that probably doesn’t matter too much when you’re using a slow 2G connection.

Elsewhere, Google has also announced that it’s expanding its rail station Wi-Fi initiative, known as Google Station, into other locations such as cafes and malls, with plans to take it to other countries. And the company will be adding Hindi support to its new AI-powered Assistant.

You may, of course, be reading this and thinking that these features seem useful anywhere, and not just in underconnected countries like India. Google would agree. Writing in the Economic Times, Google CEO Sundar Pichai explains that the company is learning a lot from its work in the country, finding that many of its solutions to connectivity issues—such as Maps Offline—are also popular in the West. “In an increasingly mobile-first world, India gives us early insights into the future of the Internet,” he explains.

But make no mistake: India is a huge opportunity for Google. If Google can be the one to provide the services that new Internet users adopt, it will be able to recoup its investments using its favorite trick of all—advertising. Facebook has already tried as much in India with its Free Basics scheme, but that was banned because it breached the principles of net neutrality.

Google, though, looks set to do everything it can to succeed.

Used Coffee Grounds Can Clean Contaminated Water

The earthy aroma of coffee in the morning is great for waking you up in the morning. But people who make a daily cup of joe generate, and toss, a helping of coffee grounds every day. Add restaurants and coffee shops into the mix and you can get tons of the brown dust. Now scientists figured out an innovative way to reduce this waste—and simultaneously help remove other toxic chemicals from the environment.

The researchers molded coffee grounds in the form of a spongey filter that absorbs heavy metals from water. The design and initial tests are described in the American Chemical Society’s journal Sustainable Chemistry and Engineering. “This product can help reduce the waste we generate,” says lead scientist Despina Fragouli, a materials scientist at the Istituto Italiano di Tecnologia.

It’s a pretty convenient solution. And though people have previously recycled coffee waste for fertilizer, animal feed, and even biodiesel, there wasn’t an efficient way of using it for water remediation until now. The chemicals in coffee, such as fatty acids, cellulose, and polyphenols, bind to heavy metals the same way activated charcoal does, but then the powder had to somehow be removed from water afterwards. So Fragouli and her team set about simplifying this process.

By adding sugar and silicone to coffee, the researchers were able to make a foamy brick that held together on its own and was easy to use as a filter. Soaking the brick in water caused the sugar to leach out and leave the coffee grounds open to bind to metal ions in the water.

In still water, a small 200-milligram piece of foam the size of an almond successfully removed 99 percent of lead and mercury ions within 30 hours. In flowing water, or water with a concentration of metal ions that exceeded 200 parts per billion, the foam’s efficiency was removed about 50 to 60 percent of the lead ions. That’s about the same efficiency that most commercially available filters have, according to Fragouli.

Fragouli says her team is working on improving the composition of the coffee and silicone mix so that it can eventually be the only filter you need. The scientists are also experimenting with other waste materials from agricultural and food industries that may have different chemical properties and could help filter out other chemicals.

“It’s very important that we find new resources to make polymers—materials that are reusable and that can replace the petroleum-based materials we currently use," says Fragouli.

Riding A Roller Coaster Could Help You Pass Small Kidney Stones

Every year around Spring Break there is a mass migration in which flocks of families from mid-Michigan flee the winter cold and head South, down to Orlando, Florida and the many theme parks there. They return a week later, satiated with fun and sun, cleansed of their worries by the vacation and their kidney stones by the roller coasters.

Yes, riding a moderately intense roller coaster for just a few minutes might be enough to dislodge those pesky kidney stones before they turn into an even bigger problem. In a paper published today in The Journal of the American Osteopathic Association, researchers showed that riding the Big Thunder Mountain Railroad at Disney World’s Magic Kingdom helped kidney stones dislodge.

Kidney stones are small mineral deposits that form in the kidney and can be very painful to pass through the urinary tract. They can result in about 300,000 emergency room visits in the United States each year, with annual costs of treating kidney stone patients at about $2.1 billion.

Urologist David Wartinger told Popular Science that the idea for the study came about eight years ago, after a patient came to see him after a spring break vacation down to Disney World. The patient had gone on a ride, the Big Thunder Mountain Railroad in Disney World’s Magic Kingdom three times in a row. That, in itself was not unusual. What caught Wartinger’s attention was the fact that after each ride the patient passed a small kidney stone, passing three stones in less than an hour.

"That really caught my attention, there was something going on here with roller coasters and renal calculi [kidney stones]" Wartinger says. "The problem was, how do you study something like that?"

Wartinger and his colleague, Marc Mitchell, tested the idea by using a silicone model kidney filled with urine and real kidney stones, then carrying it onto the ride in a backpack, positioned to align with the actual location of the kidneys. The silicone mold was 3D printed using a CT scan of an actual kidney. The silicone was chosen after thought was given to other options, including ballistic gel (which fell apart after use) and cow and pig kidneys, which the authors note in the paper would have been poor choices "owing to ambient temperature and the inappropriate display of such material in a family-friendly amusement park."

For the purposes of this study, they rode the Big Thunder Mountain Railroad 60 times with the fake kidney, noting the position of the kidney stones and re-positioning any that had become dislodged after each ride, and standing in line along with everyone else at Disney to determine where on the ride they would sit. They found that sitting in the front part of the ride resulted in a passage rate of 16.67 percent, while sitting in the back resulted in passing a kidney stone 63.89 percent of the time.

The exact mechanisms by which roller coasters help dislodge a kidney stone are still unknown, but Wartinger does have some ideas as to what’s going on. “We know that the moderate intensity coaster worked. You don’t need 70 mile an hour coasters, you don’t need precipitous drops, you don’t need inversions, you don’t need high speed turns. What I think is happening is we’re vibrating the stones loose.” Wartinger says.

But before everyone rushes to Disney World with doctor’s notes, it’s important to note that this was only one model with one set of kidney stones. The interior of kidneys are unique to each person, and kidney stones also grow in many different shapes and sizes, so this isn’t a one-size-fits-all roller coaster solution.

“The recommendation isn’t go to Disney World and ride this one coaster” Wartinger says. “Amusement theme park rides of moderate intensity have the potential to dislodge stones. So whatever coaster or park catches your fancy, you can probably benefit from attending.”

Wartinger says that three types of people could probably benefit the most from a roller coaster prescription: people that have small kidney stones, people that have had an operation to break a larger kidney stone into smaller pieces, and women who have small kidney stones and are trying to get pregnant (vitamin supplements taken with pregnancy can cause kidney stones to grow larger).

If he can get more cooperation from other theme parks, Wartinger hopes to expand the study to look at how other roller coasters affect kidney stones. And it’s not just people here on the ground that might benefit.

Kidney stones are a huge problem for astronauts on long-term missions in micro-gravity environments. While building a roller-coaster in space might be impossible, Wartinger says that it might be possible to build a device that could spin people around, jarring the stones loose, no roller-coaster required.
