The sun has "flipped upside down", with its north and south poles reversed to reach the midpoint of Solar Cycle 24, Nasa has said. Now, the magnetic fields will once again started moving in opposite directions to begin the completion of the 22 year long process which will culminate in the poles switching once again."A reversal of the sun's magnetic field is, literally, a big event," said Nasa’s Dr. Tony Phillips."The domain of the sun's magnetic influence (also known as the 'heliosphere') extends billions of kilometers beyond Pluto. Changes to the field's polarity ripple all the way out to the Voyager probes, on the doorstep of interstellar space."

Jammie Thomas-Rasset

the first US file-sharer to take her RIAA-initiated lawsuit all the way to a trial and a verdict back in 2007. Five years, three trials, and one appeal later, she owes $222,000 to the recording industry for sharing songs on the Kazaa file-sharing network, but she doesn't plan to quit fighting.

Thomas-Rasset will follow Joel Tenenbaum, the second US resident to take his file-sharing case that far. Tenenbaum—who reached the Supreme Court first because he had only one jury trial instead of three—tried to convince the justices that they should take his case to stop the music label plan to create, in his lawyer's words, "an urban legend so frightening to children using the Internet, and so frightening for parents and teachers of students using the Internet, that they will somehow reverse the tide of the digital future." The Supremes showed no interest, denying Tenenbaum's petition back in May.

The Washington Post added another noteworthy finding to the growing pile of information leaked by former NSA contractor Edward Snowden: the NSA is collecting nearly five billion cellphone location records per day from across the world.

This gigantic data collection feeds a database that stores information on "hundreds of millions of devices," according to the documents obtained by

A guitar design firm called Born to Rock has won an initial victory over the user-generated T-shirt-printing website CafePress in a legal battle over whether CafePress users will be allowed to use the company's name as part of their T-shirt designs. While the guitar firm initially registered the phrase only for use selling guitars, it has taken the position that any use of the phrase "born to rock" by a CafePress user infringes its trademarks.

The researchers suspect they've reached a region of the solar-interstellar boundary that nobody had predicted. In this area, the magnetic field lines of the Sun link up with those of the interstellar field. Scientists are calling this linkage a "highway" for particles to travel along. It lets solar wind particles escape more readily, causing the drop in their intensity. And it opens the door for low-energy cosmic rays to slip in to our Solar System, which is why Voyager 1 is seeing so many of them. According the researchers at the press conference that announced these results, most steady-state models of the Solar System failed to predict anything like this. A few models did have a feature like this, but it was only a transient one that appeared at certain times of the solar cycle.

the commission will put the newly-freed blocks of spectrum up for auction. If, as expected, the spectrum is more valuable when used for mobile services than broadcast television, then the FCC should reap significantly more from these traditional auctions than it had to pay for the spectrum in the original reverse auctions, producing a tidy profit for taxpayers.

Further evidence of overeager and illegal police work emerged Thursday in New Zealand as Inspector General of Security and Intelligence Paul Neazor released a report on the illegal bugging of Kim Dotcom and Megaupload programmer Bram van der Kolk. Two GCSB officers were present at a police station nearby Dotcom’s mansion as the raid took place.

Police weighed several options for the raid named “Operation Debut,” undertaken at the behest of US authorities, and sought to take Dotcom and associates with the “greatest element of surprise” and to minimise any delays the in executing the search and seizure operation should the German file sharing tycoon’s staff be uncooperative or even resist officers on arrival.

The police planners also noted that “Dotcom will use violence against person’s [sic] and that he has several staff members who are willing to use violence at Dotcom’s bidding” after a U.S. cameraman, Jess Bushyhead, reported the Megaupload founder for assaulting him with his stomach after a dispute. Based on Dotcom’s license plates such as MAFIA, POLICE, STONED, GUILTY, and HACKER, police said this indicates the German “likes to think of himself as a gangster” and is “described as arrogant, flamboyant and having disregard for law enforcement.” However, the documents show that Dotcom had only been caught violating the speed limit in New Zealand. The request for assistance from the STG notes that the US investigation against Mega Media Group and Dotcom was started in March 2010 by prosecutors and the FBI. According to the documents, US prosecutors and FBI “discovered that the Mega Media Group had engaged in and facilitated criminal copyright infringement and money laundering on a massive scale around the world.” FBI in turn contacted NZ Police in “early 2011," requesting assistance with the Mega Media Group investigation as Dotcom had moved to New Zealand at the time.
