According to a new study using NASA's Chandra X-ray Observatory, there's a breed of supermassive black holes out there a lot more ravenous than usual. Supermassive black holes are found in the middle of galaxies, measuring millions to billions of times the mass of our Sun. Some of them actively consume gas and dust, which form a "disc" around the mass -- as matter from that disc fall into the black hole, a jet of particles stream out, appearing as cloudy streaks. These are called quasar black holes, and they usually shine more brightly than the galaxy itself, since that disc radiates huge amounts of energy. The ones discovered by Bin Luo and his team of astronomers, however, "[dine] at enormous rates, at least five to ten times faster than typical quasars."

Store pickups give you the luxury of shopping online without waiting days for deliveries, but there's still one big hassle involved: you have to, y'know, enter the store. That won't be a problem if Nordstrom's latest experiment pans out. Several of the retail chain's locations (including its Seattle flagship) are testing an option that lets you pick up an internet order while staying in your car. All you do is call or text when you're near the shop, and a staffer will wait for you outside. There's no word on whether or not Nordstrom will expand the streetside option, but here's hoping that it does. This would not only save you time picking up a new wardrobe when you're in a rush, but spare you from hunting for that elusive downtown parking spot.

Grand Theft Auto V has a few mobile apps of its own, but one enterprising modder has taken the idea to its natural conclusion: an application that lets you control the in-game cellphone with an iPhone. With the application you can scroll through text messages on-screen, peep your current list of objectives and, among other things, even control the in-game phone's camera. The YouTube video's description (spotted by former Joystiq'r Dave Hinkle) does't offer much by way of details other than it's running on an Arduino Leonardo with an Ethernet shield connected to a PC, sadly.

NASA's ten-engine UAV, dubbed the Greased Lightning (GL-10), recently showed off a slick new trick in the skies over Hampton, Virginia. The drone, which is under development by a team at the Langley Research Center, had already passed its initial hovering tests last August; but that was the easy part. As the long and miserable development of the V-22 Osprey has shown, the real challenge is switching over from hover mode to conventional forward flight without the vehicle falling out of the sky. But on Thursday, NASA's battery-powered tilt-rotor aircraft successfully did just that.

The 787 Dreamliner has been plagued with battery woes since its early days, to the point where the Federal Aviation Administration kept it from flying the skies in the past. And while those technical difficulties are apparently taken care of, Boeing's flagship airliner could be on the way to more trouble soon. According to the FAA, there's a software bug in the 787 Dreamliner that can cause its electrical system to fail and, as a result, lead to "loss of control" of the plane. But why? The FAA says this is triggered by the aircraft's electrical generators, which could give out if they have been powered on continuously for over eight months.

Warby Parker, the eyewear company that sends you frames to try on before you make a purchase, has some lofty goals for the near future. In addition to plans that'll almost double its current retail footprint, the start-up has tech in the works that will save you a trip to the optometrist for an eye exam. "We think that would increase access to eye exams," co-founder Dave Gilboa told The Wall Street Journal. "It's early in the process but we are excited about the potential." Of course, besides the convenience, it'll also provide an avenue for folks who really need their eyes looked at to get some help at home.

After almost five years of internal turmoil and allegations, WikiLeaks is back in secret-sharing business. The site has re-launched a beta version that is accepting anonymous files starting today. Even though Julian Assange, the editor-in-chief of the site, continues to live in asylum at the Ecuadorian Embassy in London, the online submission system intends to regain its reputation as a secure site for people looking to share information of political and historical significance.

For ages, whenever you've wanted to use your Facebook credentials to log into a third party app like Foursquare or Candy Crush, you've had to give the app access to any and all data that FB has on you. There's simply been no way of choosing what information you can share--until now. Facebook announced last year that it would be implementing a new API this spring which allows the user, not the developer, to decide what sorts of private information each app is privy to. Well, that year is up and now whenever you "Log In Using Facebook," you'll be redirected to a landing page where you can select which individual data sets you want to share. Only want to tell Groupme your birthday and location? Done. Don't want to give Untappd access to your contacts? Easy.
