Have you noticed the wealth of sunrise and sunset photos on Instagram? Michelle Chandra certainly has, and her project offers a look at the sun's activity around the world in real time. "All Our Suns" gathers snapshots upload with either the #sunrise or #sunset hashtag, using the posts to populate a set of data-driven maps. Two of the crowdsourced cartography pieces catalog every image that's uploaded during the course of a 24-hour period -- one for sunrises and one for sunsets based on a user's location. What's more, you can click on a location marker to view the photo. A third map notes times when two people are posting at the same time, with one updating the beginning and the other observing the end of a day. The whole thing is a study on how our lives literally revolve around the sun and how social networks illustrate time as a never-ending loop.

Cognitive Cooking with Chef Watson is a collaboration between IBM and the Institute of Culinary Education in New York City. Once a week, as part of an ongoing series, we'll be preparing one recipe from the book until we've made all of them. Wish us luck.

Sometimes, the ingredient lists for these Watson recipes read like a Chopped contestant's worst nightmare.

Inside the basket you will find: tart shells, gruyere, sour cream and salmon filets.

Almost any time you mix cheese and fish, you know you're in trouble. (Update: I acknowledge that both tuna melts, and bagels with cream cheese and lox are rare exceptions to this rule.) But, if anyone is capable of taming the culinary cruelty of Watson it would be the brilliant minds at the Institute of Culinary Education, like Florian Pinel and Michael Laiskonis. So, even though the idea of a Scandinavian salmon quiche is a little off-putting, I put my faith in the human interpreters to steer me and my captive taste testers in the right direction.

Marines on a sunny golf course in Quantico, Virginia, this week demonstrated a pair of augmented reality glasses that simulate combat scenarios. The Office of Naval Research recently completed development of the goggles and this week hooked them up to a larger training system known as the Augmented Immersive Team Trainer for the first time. Representatives from the Army, Navy and Marine Corps showed up at Marine Corps Base Quantico to see the AITT in action. The AR glasses themselves have a wider field of view than similar products on the commercial market, and the full AITT experience incorporates real-life weapons props, binoculars and other physical equipment necessary in a potential combat zone. "For Marines, this system increases their situational awareness, whether for training or operations, giving them a wider aperture for information to help make better decisions," ONR action officer Le Nolan said.

An unassuming, Mormon family man. A brilliant physics and engineering student with a goofy smile. Five years ago, neither of these men knew each other, let alone suspected that they'd be drawn into a web suffused with libertarian dogma, hard drugs and the sort of rhetorical dedication that allegedly drove that student -- Ross Ulbricht -- to order a hit on that family man.

That's the weighty world that digital documentarian Alex Winter set out to explore in his new film, Deep Web. By his own admission, the documentary -- which first appeared at SXSW in March and hits Epix on May 31st -- can't tell the whole story of the Silk Road, an anonymous bazaar of hallucinogens, hitmen and, really, whatever you were looking for. Ulbricht is still behind bars after being found guilty of all seven charges leveled at him earlier this year, which included narcotics trafficking, computer hacking and money laundering. One even crowned him a "kingpin," and stuck him with the punishment attached to the title. While he and the rest of us wait to see what his sentencing holds, though, Deep Web acts as an important crash course in the events that led to all this. We spoke to director Winter to understand how and why he put the story together on film.

An optometrist in British Columbia claims to have invented an easily implantable device that provides its wearer with vision "three times better than 20/20" for life. Dubbed the Ocumetics Bionic Lens by its inventor Dr. Garth Webb, this device appears to be very similar in structure to the conventional artificial lenses employed in cataract surgery. The eight-minute installation procedure is reportedly painless. It involves injecting the folded lense into your eye where it unfurls to replace your natural lense and correct your vision. There's also an added benefit in that with these artificial lenses in place, you'll never develop cataracts.

It took 100 hours of research and testing conducted by an airborne particle physicist and former NOAA scientist using $100,000+ of equipment to find the best air purifier for most people: The $250 Coway AP-1512HH Mighty. It's as effective at removing particulate contaminants (such as pollen, spores, smoke, and dust) as machines over twice its size and costing twice as much. But the best air purifier for you personally depends on your specific needs, which is why we have other recommendations.

Earlier this week, folks in the know claimed that Apple's HDTV project had been junked after more than a decade of development. Now, however, Re/code is reporting that the company is still working on an online TV service for its devices, but wants to beat its rivals by being the first to offer live video from local broadcasters. Naturally, a push for regional content means having to deal with the hundreds of affiliates that operate across the country. So, instead of just shaking hands on a contract with ABC, Apple's got to get lawyers out to every station from Arizona's KNXV-TV to Wyoming's WAOW.

Samsung's new wireless headphones are a worthy contender

Last summer, I spent some time getting to know the first four entries in Samsung's "Level" audio line. There's a new item this year, though: a wireless version of the original Level On headphones. In case you missed the first roundup, this model is an on-ear option, and it ended up being my favorite of the bunch. But with the bulk of the features being the same, is the extra $80 worth it to go wireless?

There comes a point in every zeitgeisty app's life when it wonders if it should stop eating nothing but Doritos and having those drunken one-night stands and become a mature, serious business. We've already seen Snapchat evolve from a way to distribute pictures of your genitals to a news broadcast system, and now Tinder is seriously considering becoming a music promoter. The dating app has just signed a deal with Interscope Records to promote the new album from Russian DJ Zedd.

Kids looking at ipad / tablet in classroom

DirecTV saw what YouTube and Netflix were doing with their kid-focused apps, and decided that it, too, wanted a piece of that action. After many months of toil, the company has busted out DirecTV Kids, an iOS app that lets your rugrats consume content from your cable package at no extra cost. Designed for 5-10 year-olds, the offering lets your kids watch shows anywhere, and can be used on up to five devices at once. It's available for free from the App Store, and is likely to be a bit safer than YouTube's rival, at least as far as parental groups are concerned.
