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."

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 authors of the article note several similarities with the bizarre and enigmatic soft-bodied life forms that lived between 635 and 540 million years ago - the span of Earth history known as the Ediacaran Period.

The authors of the paper recognise two new species of mushroom-shaped animal: Dendrogramma enigmatica and Dendrogramma discoides.

a bail revocation application is underway which could put back behind bars as early as next week.

Last week it was revealed that his New Zealand legal team had backed out of their arrangement to defend the Megaupload founder.

A full report on developments isn’t possible due to a news blackout, but Crown Prosecutor Christine Gordon told the Court that an application had been made to have Dotcom’s bail revoked after an apparent breach of conditions.
