NSA reportedly recommends retiring phone surveillance program

first_imgThe National Security Agency has recommended the White House abandon a controversial program that collects and analyzes data on millions of Americans’ domestic calls and texts, The Wall Street Journal reported Wednesday.The recommendation against renewing the program represents a dramatic reversal from the longstanding position of the agency, which had argued that the program was vital to identifying and disrupting terrorist activities. The program, which was put in place after the 2001 terrorist attacks, has legal and logistical burdens that outweigh its value to national security, sources told the Journal.The reported recommendation comes a little more than a month after a national security advisor revealed that the NSA hasn’t used the system in months. Luke Murray, an advisor for Republican House minority leader Kevin McCarty of California, also said at the time the White House might not seek to renew its legal authority to operate the program.The NSA had been collecting large amounts of metadata, the digital information that accompanies electronic communications, under a controversial national security policy put in place by the Patriot Act in 2001. That information included what phone numbers were on the call, when the call was placed and how long it lasted, which was then saved in a database.The already heated debate over the Patriot Act programs intensified in 2013 when former NSA contractor Edward Snowden leaked documents detailing the ways in which the secretive US government agency was collecting data. A new system put in place by Congress in 2015 required federal agencies to seek a court order on a case-by-case basis to obtain call data from telephone companies.The USA Freedom Act of 2015, legislation designed to curtail the federal government’s sweeping surveillance of millions of Americans’ phone records, is set to expire at the end of year, if the Trump administration doesn’t ask Congress to renew its authority to continue the program.The NSA and White House didn’t immediately respond to requests for comment. 6 Now playing: Watch this: 4:25 NSA Security Tech Industrycenter_img Share your voice Comments Yes, Facebook is still tracking you (The 3:59, Ep. 541) Tagslast_img read more

Research station on skis withstands Antarctic ice and snow

In consideration of the residents’ psychological needs, a central red module, intended for use as a social space, contains communal dining areas, a hydroponic garden, and climbing wall. Colors were even chosen on the advice of a color psychologist. Construction of Halley VI began in Capetown, South Africa. The first modules were shipped to Antarctica at the end of 2007.

Halley researchers also perform glaciology and geology studies. Notably, scientists first recorded ozone layer depletion in the stratosphere above the Antarctic here.Antarctic conditions have caused problems for Halley research bases. Accumulated snow, measured at more than three feet per year, crushed buildings in the first four bases. Movement of the ice shelf toward the ocean at an annual rate of a quarter of a mile means that research stations are at risk of falling into the ocean when ice separates from the mainland. These factors give buildings that cannot be moved a lifespan of only ten years. Halley VI, commissioned in 2006, consists of eight connected modules, each of which sits atop hydraulic legs. The legs allow the individual modules to be raised above the snow. Additionally, placement of the modules at a right angle to the prevailing wind encourages snow to blow underneath the station. Skis positioned beneath the legs allow inland towing of each module, thereby minimizing its proximity to the ocean. Antarctica Halley VI Halley V had extensible steel legs, allowing operators to maintain the buildings above the snow’s surface. The legs, though raised every year, were eventually trapped in 75 feet of ice. Because the station was rendered immobile, it was carried along with the ice and was therefore at risk of plummeting into the ocean when the ice caved.In June 2004, the British Antarctic Survey and the Royal Institute of British Architects (RIBA) launched a competition to design a new research station. In addition to being able to cope with moving ice and heavy snow accumulation, this new station would have to provide psychological comfort to the station’s residents—around 70 in summer and around 16 in winter—who are at great risk of stress and depression related to the harsh Antarctic weather and permanent lack of sunlight in winter.

The Halley VI Antarctic Research Station, designed by Hugh Broughton Architects, utilizes a modular design that incorporates hydraulic legs fitted with skis. This design allows Halley VI to survive in conditions that have destroyed its five predecessors. The Halley VI modules at the Halley VI site. Credit: British Antarctic Surveylast_img read more
