Sun’s coronal ejections caused by magnetic ropes, galactic weathermen to predict solar storms?

Space weather gets nasty when the sun starts shooting plasma into the cosmos, and these solar storms wreak havoc on both satellites and gadgets here on earth. Scientists want to predict the sun’s eruptions so we can protect our gear (and know the best time to go tanning), and George Mason University researchers have made a discovery that may help us do so. By examining images from NASA’s Solar Dynamic Observatory spacecraft, Professor Jie Zhang and grad student Xin Cheng determined that magnetic ropes are causing coronal ejections. The ropes are formed by several magnetic fields wrapped around each other, and scientists believe they can carry electrical currents strong enough to cause the plasma bursts. Prior to an eruption, Zhang observed a low-lying channel with unique electromagnetic properties (believed to be a magnetic rope) heat a portion of the sun’s surface up to 10 million degrees. Once hot enough, the spot spewed forth copious amounts of the plasma and magnetic energy that gives GPS units and phones fits. Now that we know what gets Helios all riled up, we just need to find a way to calm him down. Close-ups of the sun in its tizzy are after the break.

Kobo eReader Touch Edition goes on sale in the US and Canada

At the moment, there are two very similar-looking e-readers with black-and-white Pearl E Ink touchscreens on the market, and now, the smaller and less expensive of the pair is up for grabs. The Kobo eReader Touch Edition went on sale today in the US and Canada for $129.99 (or $139.99 Canadian) at Best Buy, Borders, Walmart, and the Canadian bookseller Indigo. If you’ll recall, the 6-inch Kobo is thinner, lighter, and more compact than the Nook Touch, even though its screen is the same size. It also undercuts it by $10 but it lacks the convenience of any physical buttons. Could these trade-offs be worth the trimmer design? We’ll leave that to you and your wallet (and the guy who may or may not receive this as a last-minute Father’s Day gift).

Microsoft gets antitrust okay for Skype purchase, readies shockingly large wire transfer


Look out, world — Microsoft just crossed another hurdle in its bid to swallow Skype whole. Earlier today, US antitrust approval was given on Microsoft’s largest (proposed) acquisition, clearing the path for all sorts of Windows / Xbox / WP7-related VoIP shenanigans. While many are still questioning the logic here, Skype continually brought around 145 million users to the table per month even while it constantly bled money. Whatever the case, it looks as if the accountants in Redmond just got FTC permission to move $8.5b from one column to the next, and with an initial investment like that, we’re hoping for a number of updated features as the attack plan unfolds.

Netflix’s day: Sony movies pulled, new bandwidth options, no more DVD API access and a lawsuit

In an apparent ode to Rebecca Black, Ice Cube and any number of body switch movies, Netflix has had an incredibly active Friday, so sit back while we get you up to speed. Sony Pictures movies from Starz Play are no longer available (on any device, not just the Xbox 360 this time) due to a “temporary contract issue” according to the official blog. According to NewTeeVee, the problem is an “IP distribution cap” that was reached due to Netflix’s explosive growth, but with no word on when the movies will be back, you’ll be missing The Other Guys. Up next was the National Association of the Deaf, which has filed a lawsuit in Springfield, MA against Netflix, claiming that its failure to provide closed captions on all streaming content puts it in violation of the Americans with Disabilities Act. Netflix last claimed 30 percent of titles were subbed with plans to reach 80 percent by the end of the year, but the press release (and captioned YouTube video) make the case that as a leader in streaming video, it should do better.

Netflix also quietly gave US subscribers access to the same bandwidth management options provided to Canadians a few months ago. The new Manage Video Quality settings (shown above) can be found in the Your Account section, and if you’re trying to stay under bandwidth caps or just keep seeing buffering, they should help you out at the cost of a few pixels. As if that wasn’t enough, the Netflix Tech Blog squeezed in news that it was ending access to “DVD-related features” for apps using its Open API later this year. The move is apparently preparation for expanded international streaming, so if you’re trying to manage discs through a third party things may change soon.

RIM shares hit a five-year low: oh, how the mighty have fallen

There was a time when RIM owned the smartphone space with its revolutionary push email-equipped BlackBerrys. And there are still plenty of folks who can’t live without a good physical keyboard and BBM. But, despite the company’s $4.9 billion in revenue and $695 million in profits from Q1 2011, RIM’s stock has tumbled to its lowest price in five years. What’s changed since those heady days when it seemed like there was a Pearl in every pocket? As many of you know, Androids and iPhones have carved out a big chunk of the smartphone market, largely at RIM’s expense. Sure, Blackberry 7 OS is coming and the PlayBook is rolling out to help the company gain ground on Android and iOS, but only time will tell if these latest efforts from Waterloo can stem the rising tide of iPhones and little green bots.

So, we knew the Galaxy Tab 10.1 was coming, but it looks like some shoppers eagerly anticipating the tablet’s arrival will go home empty handed today. We just received word from a Samsung rep that there have been “shipping delays to some stores in certain regions.” They went on to say, “We expect most retail locations to have inventory by tomorrow while supplies last.” That’s all we have at the moment, but we’ll keep you posted as soon as we know more.
