CNET has learned a constellation of law enforcement groups has asked the U.S. Senate to require that wireless companies retain that information, warning that the lack of a current federal requirement "can hinder law enforcement investigations." They want an SMS retention requirement to be "considered" during congressional discussions over updating a 1986 privacy law for the cloud computing era -- a move that could complicate debate over the measure and erode support for it among civil libertarians. As the popularity of text messages has exploded in recent years, so has their use in criminal investigations and civil lawsuits. They have been introduced as evidence in armed robbery, cocaine distribution, and wire fraud prosecutions. In one 2009 case in Michigan, wireless provider SkyTel turned over the contents of 626,638 SMS messages, a figure described by a federal judge as "staggering."

“The government does not cite a single case in which analysis of the NSA’s bulk metadata collection actually stopped an imminent terrorist attack,” the judge wrote.

“Given the limited record before me at this point in the litigation – most notably, the utter lack of evidence that a terrorist attack has ever been prevented because searching the NSA database was faster than other investigative tactics – I have serious doubts about the efficacy of the metadata collection program as a means of conducting time-sensitive investigations in cases involving imminent threats of terrorism.”

The project, which cost a total of $1.8 billion to construct, received a million-dollar loan from the Loan Programs Office. Under its “SunShot” initiative (so-named in the spirit of president John F. Kennedy’s “moon shot” program), the DoE provides guaranteed loans to unproved ventures in solar power in the hopes of promoting innovation and making the technology more cost-effective.* Although Agua Caliente (owned by U.S. energy giant NRG Energy and partner MidAmerican Solar) is now the largest photovoltaic solar facility in the world, it probably will not hold that distinction for long. Other massive solar panel facilities, such as Antelope Valley Solar Ranch One in California’s Mojave Desert, are rapidly springing up across the Southwest.

The practice contradicted what Mr. Verrilli had told the Supreme Court last year in a case challenging the law, the FISA Amendments Act of 2008. Legalizing a form of the Bush administration’s program of warrantless surveillance, the law authorized the government to wiretap Americans’ e-mails and phone calls without an individual court order and on domestic soil so long as the surveillance is “targeted” at a foreigner abroad. A group of plaintiffs led by Amnesty International had challenged the law as unconstitutional. But Mr. Verrilli last year urged the Supreme Court to dismiss the case because those plaintiffs could not prove that they had been wiretapped. In making that argument, he said a defendant who faced evidence derived from the law would have proper legal standing and would be notified, so dismissing the lawsuit by Amnesty International would not close the door to judicial review of the 2008 law. The court accepted that logic, voting 5-to-4 to dismiss the case. In a statement, Patrick Toomey, staff attorney with the American Civil Liberties Union, which had represented Amnesty International and the other plaintiffs, hailed the move but criticized the Justice Department’s prior practice.

Still, it remains unclear how many other cases — including closed matters in which convicts are already service prison sentences — involved evidence derived from warrantless wiretapping in which the National Security Division did not provide full notice to defendants, nor whether the department will belatedly notify them. Such a notice could lead to efforts to reopen those cases.

According to internal NSA documents viewed by SPIEGEL, these on-call digital plumbers are involved in many sensitive operations conducted by American intelligence agencies. TAO's area of operations ranges from counterterrorism to cyber attacks to traditional espionage. The documents reveal just how diversified the tools at TAO's disposal have become -- and also how it exploits the technical weaknesses of the IT industry, from Microsoft to Cisco and Huawei, to carry out its discreet and efficient attacks. The unit is "akin to the wunderkind of the US intelligence community," says Matthew Aid, a historian who specializes in the history of the NSA. "Getting the ungettable" is the NSA's own description of its duties. "It is not about the quantity produced but the quality of intelligence that is important," one former TAO chief wrote, describing her work in a document. The paper seen by SPIEGEL quotes the former unit head stating that TAO has contributed "some of the most significant intelligence our country has ever seen." The unit, it goes on, has "access to our very hardest targets."

This is a fundamental problem for nations that aren't interested in exposing their traffic to American observation, whether they're engaged in nefarious activities or not. Long term, the problem could lead to the construction of digital firewalls, in which the United States is effectively isolated behind protective nodes built by local governments to scrub and redirect traffic away from potential capture points. This is directly in opposition to the central concept of the Internet, which is a dynamic structure capable of responding to outages or damage by routing around the problem.

The FBI has an elite hacker team that creates customized malware to identify or monitor high-value suspects who are adept at covering their tracks online, according to a published report.

one issue was left conspicuously unaddressed in the report. The Securities and Exchange Commission, the civil agency in charge of protecting investors and ensuring orderly markets, has been advocating for a special exception to the warrant requirement. No agency can or should have a get-out-of-jail-free card for bypassing the Fourth Amendment.

With a surveillance reform bill stuck in the Senate, the federal court overseeing spy agencies on Friday reauthorized the National Security Agency’s controversial bulk collection of Americans' phone records.

The NSA’s phone records program needs to be reauthorized by the FISC every 90 days. The current authority expires on Dec. 5.

The European Space Agency's satellite array dubbed “Swarm” revealed that Earth's magnetic field is weakening 10 times faster than previously thought, decreasing in strength about 5 percent a decade rather than 5 percent a century. A weakening magnetic field may indicate an impending reversal, which scientists predict could begin in less than 2,000 years. Magnetic north itself appears to be moving toward Siberia.

There is a good chance the weakening magnetic field that the Swarm satellites observed will not lead to a full flip. Indeed, Glatzmaier notes that there have been several false starts over geologic history. The intensity of Earth's magnetic field, though waning, now equals its average strength over millions of years. The field would need to weaken at its current rate for around 2,000 years before the reversal process actually begins.

It is hard to know how a geomagnetic reversal would impact our modern-day civilization, but it is unlikely to spell disaster. Although the field provides essential protection from the sun's powerful radiation, fossil records reveal no mass extinctions or increased radiation damage during past reversals. A flip could possibly interfere with power grids and communications systems—external magnetic field disturbances have burned out transformers and caused blackouts in the past. But Glatzmaier is not worried. “A thousand years from now we probably won't have power lines,” he says. “We'll have advanced so much that we'll almost certainly have the technology to cope with a magnetic-field reversal.”

The National Security Agency listed Israel among a handful of nations considered to pose the “greatest threat” to American government, military and industrial secrets, classified documents leaked by whistleblower Edward Snowden reveal.
