Submission + - Cell Carriers Responded to 1.3 million Law Enforcement Requests for Data. (nytimes.com) 1
In the first public accounting of its kind, cellphone carriers reported that they responded to a daunting 1.3 million demands for subscriber data last year from law enforcement agencies seeking text messages, caller locations and other information in the course of investigations.
One stinging statistic: AT&T gets 230 requests for data per hour, and turns down only 18 per week. Sprint gets 500,000 requests per year. While many requests are backed by court orders, most are not. Some include "dumps" of tower data, which captures everyone near by at a certain time."
Submission + - Icelandic MP Claims US vendetta against Wikileaks (guardian.co.uk)
What's new? She asserts that there is a grand jury investigation into Wikileaks and related organizations, and is calling on Sweden to provide assurances that Wikileaks founder Julian Assange not be re-extradicted to the US."

More likely it is the speed of deployment, the ability to strike targets without going high enough to be seen by many advance warning radars, and without using nuclear warheads makes it a precision surprise attack weapon, a kind of super cruise missile for surprise asymetric attacks."

Submission + - Paper Disputes Closing Ivins Anthrax Case (nytimes.com)
it appears likely that Dr. Ivins could not have made the anthrax powder alone with the equipment he possessed, as the F.B.I. maintains. That would mean either that he got the powder from elsewhere or that he was not the perpetrator.
For a good summary of the case from a medical standpoint this article from the Annals of Internal Medicine is an excellent place to start. The review by the National Resources Council that stated that the evidence available was not sufficient to locate the source of the spores is here, with a free pdf download."
Submission + - Oldest Submerged City Visualized with CGI and Ster (nottingham.ac.uk)
The result is a BBC documentary that features a detailed CGI reconstruction. The Independent chimes in about the oldest known submerged city first inhabited 5000 years ago and was rediscovered in 1967. Of course, Slashdot readers will want to dig into the (pdf) how stereo mapping was used to create the map in the first place."
Submission + - Dan Schechtman wins 2011 Nobel Chemistry for quasi (nobelprize.org)
So what's the big deal? A quasi-crystal is to a crystal, what a transcendental number is to a repeating decimal. A fraction like 1/3 written out never ends, but it never changes, just like ordinary squares cover a flat surface, by repeating over and over again, or cubes fill a space. Quasi crystals fill space completely, but do not repeat, even though they show self-similar patterns, the way pi has order, but doesn't repeat. That is, the tessellate in an ordered way, but do not have repeating cells.
In art Girih tiles showed the essential property of being able to cover an infinite space, without repeating. In mathematics, Hao Wang came up with a set of tiles that any Turing Machine could be represented by, and conjectured that they would eventually always repeat. He turned out to be wrong, and over the next decades, tiles that did not repeat, but showed order, were discovered, most famously, though not first, by Penrose.
Physically, when x-rays diffract, that is are scattered, from a crystal, they form a discrete lattice. Quasi-crystals also have an ordered diffraction pattern, and it tiles the way ordered by non repeating tiles do. Quasicrystal patterns were known before Schechtman labelled them.
So why care? Because crystals have only certain symmetries, and that determines their physical properties. Quasicrystals can have different symmetries, and do not bind regularly, and so different physical properties – which means new kinds of materials. Some examples are for highly ductile steel, and in something that is a bit of a by-word among people who study them cooking utensils."
Submission + - Climate Change Driving War? (sciencemag.org)
"As the Thirty Years' War between Europe's ruling dynasties dragged on during the 17th century, soldiers suffered through the coldest few decades Europe had experienced for some time. Far to the east, armies from Manchuria (present day northern China) swept down from the snowy north and breeched the Great Wall of China. Not long after, a plague swept Europe. Why so much tumult? A controversial new study suggests that most of humankind's maladies—from wars to epidemics to economic downturns—can be traced to climate fluctuations.
