After tense months of research, the U.S. Air Force has announced that it has located the cause of "hypoxia-like" symptoms that have been observed in F-22 Raptor pilots. This is good news for the Air Force, as the breathtakingly expensive aircraft has been repeatedly grounded and severely limited during the ongoing investigation. Now, those limitations will be coming to an end soon.

After months of waiting, Apple's next major operating system upgrade Mountain Lion is now available for download in the Mac App Store. This new iteration of the software, version 10.8 if you're keeping score at home, continues Apple's move toward unifying iOS and MacOS into one seamless experience.

Olympic fever is nearing its zenith, and artists seem to have taken notice. Animators Leo Bridle and Amael Isnard present their own slightly warped view on these events in their short film Olympic Vermin. If you enjoy adorable animals performing endurance events in order to light an "eternal" flame, then you are in luck, my friends.

Conan O'Brien is a lot of things: Comedian, musician, Tilda Swinton stand-in. But he is not a gamer. However, that has not stopped him from trying in a series of review videos called "Clueless Gamer." This week, the object of his bemusement was Minecraft. Things were off to a great start where, within seconds, the late-night funnyman compared it to 19th century Wales. I think he gets it. See the video, after the break.

We love imaginative LEGO sets here at Geekosystem, but we've often neglected the amazing world of LEGO minifig customization. This collection of 16 characters from Street Fighter 2 by Julian Fong demonstrates just what we've been missing out on. See the full collection, after the break.

Yesterday, the security research group F-Secure received a puzzling email claiming to be from a nuclear scientist with the Atomic Energy Organization of Iran (AEOI). In it, the author claimed that the country's nuclear facilities were once again under attack. Only this time, the hackers brought Angus Young along for the ride.

By this point, you are no doubt aware that the U.K. Ministry of Defence is installing surface-to-air missiles around London as a deterrent against would-be airplane hijackers during the Olympics. As you can imagine, some people are unhappy about the idea of having heavy weapons next door. Popular street artist Banksy doesn't seem too happy about it either.

There is no doubt in anyone's mind that after the stupendously successful launch of the Kindle Fire last year -- and the amazing surge in tablet use that followed -- that Amazon will be trotting out new hardware soon. In fact, some reporters have even touched prototype devices. However, the number of new devices has just doubled from previous reports. This could be a big year for Amazon.

For some of you (particularly, our U.K. readers) this will probably not come as a surprise, but the "City of London" is not actually "London." In fact, as the great Internet explainer C.G.P. Grey reveals, the City of London is sort of its own thing within what we normally call London today. How this came to pass involves a little explaining about parliamentary democracy, history, and military construction, but it's imparted in just under five minutes.

It's that great American story: A man, his son, and their Nexus 7 tablet alone against the elements. In this, the first advertisement for the highly anticipated Google Android tablet, we see the device in its natural habitat. See the surprisingly charming video below.

In case yesterday's reminder that the universe is a beautiful place wore off, this short piece from Goldpaint Photography is a dreamy look at the night sky. The time lapse video shows off the spiraling stars, the quiet woods, and some tantalizing hints of an aurora. Watch it, and just chill a while.

When we last checked in on the potential exoplanet Gliese 581 g, things were looking good for it to exist in the habitable "Goldilocks region" where liquid water can exist on the surface of a planet. Then, there were concerns that the rocky world might not exist at all. Now, the University of Puerto Rico at Arecibo has placed the planet at the top of its list of potentially habitable exoplanets.

At a midnight premiere of The Dark Knight Rises in Aurora, CO, a six-foot-tall man dressed in riot gear entered theater 9 at the Cinemark 16. According to reports, he opened a cylinder of tear gas and then began firing into the audience at random. The horrific shooting has left 12 people dead, and dozens more injured.

First we saw the teaser, then we saw the other teaser, and now the full-length trailer for the forthcoming film The Master is at last revealed to us. While it's a bit weird to get this worked up about trailers, this controversial film about a cult in post-war America looks stunning. See it, after the break.

Despite Google bringing the South Pole to your computer, there are some sights that have to be witnessed first hand to really be appreciated. Such is likely the case for this picture, taken outside the Concordia base in Antarctica. In the bitter, freezing night, the southern lights -- aurora australis -- put on an incredible show with the Milky Way.
