NASA captures red sprite, puts it in a jar
Lightning doesn't always shoot downwards. Just occasionally, a thunderstorm will be accompanied by a red sprite: a huge, momentary electrical explosion that occurs around 50 miles high and fires thin tendrils many miles further up into the atmosphere. Sprites have been caught on camera before, but a fresh photo taken by arty astronauts on the ISS helps to show off their true scale. Captured accidentally during a timelapse recording, it reveals the bright lights of Myanmar and Malaysia down below, with a white flash of lightning inside a storm cloud and, directly above that, the six mile-wide crimson streak of the rare beast itself. Such a thing would never consent to being bottled up and examined, but somehow observers at the University of Alaska did manage to film one close-up at 1000 frames per second back in 1999 -- for now, their handiwork embedded after the break is as intimate as we can get.
AMD strikes CES with brand new APUs and Lightning Bolt
AMD decided to steer clear of the show floor this year, instead choosing to stick to a briefing room upstairs, where they gave us a quick tour of their current offerings as well as a sneak peek at some upcoming projects. There were two big stars, though, the first of which is the upcoming Trinity APUs, based on its Piledriver core. There will be three different versions: desktop, laptop and "thin and light." The latter of which is clearly aimed at Ultrabook-like form factors and draws just 17W, while promising similar performance to current generation 35W chips. To show off just how powerful its next-gen architecture is AMD demoed a machine playing DiRT 3 (at low quality mind you) on one display, transcoding video on another and playing a clip of a kata on third. Oh, and that third display was attached to the laptop that was driving the whole thing without stuttering. The other big news, though we sadly don't have accompanying visuals, was a backroom demo of Lightning Bolt -- AMD's answer to Thunderbolt. The protocol is capable of driving up to four displays and several USB 3.0 ports while providing power. It can only drive two at 1080p and it won't reach the full speed of USB 3.0, but AMD did say it will be faster than 2.0. Supposedly the tech will be incredibly cheap in integrate into a PC, and a single cord running from a DisplayPort to a hub was able to handle playing back a Blu-ray and transferring files from a thumb drive while pushing two 1366 x 768 monitors -- not bad for an early prototype. Check the gallery above for a few shots of the latest AMD APUs and, for more technical details, hit the more coverage links.
NASA's Cassini can hear it when lightning crashes on Saturn
Some folks can fall asleep to the calming pitter patter of gentle rain. Yeah, we're not those people. But we could be swayed into a somnolent stupor if those sounds came from epic storms -- on Saturn. Captured by NASA's Cassini probe last March, this 11-second clip of AM radio-like electrostatic is actually the agency's first glimpse into storm activity on the planet's Northern Hemisphere. Alright, so we admit the recording's more of a weak 'snap, crackle and fizzy pop' than outright terror-inducing awe, but still these are the noises of another world. Would it help if we told you this storm's been raging since December 2010 and hasn't shown any signs of stopping? Shocking, we know. It's not all doom and gloom, though as the folks behind Cassini think this is simply a sign of impending summer. So basically, it's spring break at the saturnine Señor Frogs. Check the source for a sample of otherworldly rumbles.
Totem Talk: Enhancement Cataclysm update
Axes, maces, lightning, Windfury, and wolves. It can mean only one thing: enhancement. Rich Maloy lives it and loves it. His main spec is enhance. His off-spec is enhance. He blogs about the life and times of enhance, and leads the guild Big Crits (Week 9 now out!) as the enhancement shaman Stoneybaby. With such a lame title, you'd never guess we have so much to talk about this week! Mastery bonus is all elemental damage, not just nature! Smarter Searing Totems! Four Ghostcrawler replies (11 paragraphs!) about Shamans, with four paragraphs solely about Enhancement! Longer Hex! New crit-increasing talents! Increased totem ranges! Well, okay, maybe that last one isn't as exciting as the first few. But there's so much news out there for us enhancers, I don't even know where to begin. The logical place to start is with the biggest news: Enhancement Mastery bonus "increases all elemental damage done by 20%. Damage increased further by mastery rating." This is a change from the first Cataclysm build that included mastery; previously our bonus was only increasing our nature damage. The nature-only mastery was great for our core spell, Lightning Bolt (LB), but with Maelstrom Weapon (MW) now including Lava Burst (LvB) we would not benefit from our Mastery bonus with LvB. This was a problem for two reasons: first LvB does more damage than LB, and second, LvB could be used to keep Elemental Devastation up. Lava Burst will automatically crit when Flame Shock (FS) is on a target, making it a smart choice to used to keep Elemental Devastation active. That choice changed. Mastery now affects all elemental damage, which includes Lava Burst. Hence, Lava Burst plus Flame Shock plus mastery equals happy enhancer. This is a great buff for us. Because LvB has an 8 second cooldown and LB has none, we'll still keep LB handy for when LvB is on cooldown.
