By SHIRLEY S. WANG ( See Corrections & Amplifications item below .) The risk of cancer associated with popular CT scans appears to be greater than previously believed, according to two new studies published Monday in the Archives of Internal Medicine. The findings support caution against the overuse of CT scans and other medical technologies that use radiation. The studies also bolstered the rationale behind controversial new breast-cancer screening guidelines, which pushed back the recommended age for annual mammograms to 50 from 40.
Internal Homeland Security documents describing specifications for border-crossing scanners, which emit gamma or X-ray radiation to probe vehicles and their occupants, are raising new health and privacy concerns, CNET has learned. Even though a public outcry has prompted Homeland Security to move away from adding X-ray machines to airports--it purchased 300 body scanners last year that used alternative technology instead--it appears to be embracing them at U.S.-Mexico land border crossings as an efficient way to detect drugs, currency, and explosives. The Z Portal scanner in use at the San Ysidro, Calif., border crossing uses high energy X-ray radiation to probe the interior of vehicles. Homeland Security says it's safe for humans, but some biophysicists disagree. (Credit: AS&E)
Federal V.I.P Penn - 11/13/02 Last Thursday I was flying to LA on the Midnight flight. I went through security my usual sour stuff. I beeped, of course, and was shuttled to the "toss-em" line. A security guy came over.
On the day after Christmas, readers of The Washington Post were given a real treat: pictures of naked men. The men in the pictures were fully clothed, but they were naked nonetheless, because the pictures came from airport full-body scanners. Continue Reading VIDEO: Napolitano on security The machines provided graphic pictures of the male anatomy. True, they were no more graphic than Michelangelo’s David or Leonardo da Vinci’s Vitruvian Man (that’s the naked guy with his arms and legs stuck out), but both of those were depictions, not actual people trying to heft their wheelie bags on the conveyor belt, take off their shoes and jackets, remove their laptops, take out their baggies full of fluids no more than 3 ounces in size, take the metal out of their pockets and somehow get through security before their planes take off.
February 21, 2011 The latest opt-out: An Alaska state lawmaker is returning home by sea after refusing a pat-down search at a Seattle airport, a spokeswoman said.
Now that she’s sold her private jet , Sen. Claire McCaskill is airing her grievances about flying commercial. The Missouri Democrat told Transportation Security Administration chief John Pistole on Wednesday that she is an “expert” on commercial air travel, and that with her artificial knee, she tries her hardest to avoid what she calls “unbelievably invasive” pat-downs in favor of the Advanced Imaging Technology scanning machines. Continue Reading McCaskill keeps an eye out for one TSA agent in particular.

At the beginning of December, we warned the Copyright Office that operating system vendors would use UEFI secure boot anticompetitively, by colluding with hardware partners to exclude alternative operating systems. As Glyn Moody points out , Microsoft has wasted no time in revising its Windows Hardware Certification Requirements to effectively ban most alternative operating systems on ARM -based devices that ship with Windows 8. The Certification Requirements define (on page 116) a "custom" secure boot mode, in which a physically present user can add signatures for alternative operating systems to the system's signature database, allowing the system to boot those operating systems. But for ARM devices, Custom Mode is prohibited: "On an ARM system, it is forbidden to enable Custom Mode. Only Standard Mode may be enable." [sic] Nor will users have the choice to simply disable secure boot, as they will on non-ARM systems: "Disabling Secure [Boot] MUST NOT be possible on ARM systems."
EPIC - FOIA Documents Reveal Homeland Security is Monitoring Political Dissent As the result of EPIC v. DHS, a Freedom of Information Act lawsuit , EPIC has obtained nearly thee hundred pages of documents detailing a Department of Homeland Security's surveillance program. The documents include contracts and statements of work with General Dynamics for 24/7 media and social network monitoring and periodic reports to DHS. The documents reveal that the agency is tracking media stories that "reflect adversely" on DHS or the U.S. government.
This will be short and “sweet.” Like many of you, when I think of a cupcake, I don’t think of it being in a jar. However, the photo below shows the “cupcake” that was prohibited from being taken into the cabin of a plane last month.
Carnival Booth: An Algorithm for Defeating the Computer-Assisted Passenger Screening System Samidh Chakrabarti Aaron Strauss 6.806: Law and Ethics on the Electronic Frontier
The MBTA has been conducting random security inspections regularly since October 2006. Passengers are selected on a random basis through the use of a computer generated sequence of numbers. These inspections involve the brushing, with a swab, of the exterior of a carry-on.
TSA is looking for vendors that could help it measure the levels of ionizing radiation that its security screeners are exposed to at U.S. airports. “The measurements will assist the TSA in determining if the Transportation Security Officers (TSO) at selected federalized airports are exposed to ionizing radiation above minimum detectable levels, and whether any measured radiation doses approach or exceed the threshold where personnel dosimetry monitoring is required by DHS/TSA policy,” says a request for information (RFI) document made public by TSA on Dec. 29, 2011. The agency is required by federal safety regulations to undertake periodic examinations of its radiation-emitting equipment. In response to an inquiry by Government Security News , TSA spokesman Mike McCarthy said on Jan. 4 that the recently-issued RFI did not reflect any heightened concern by the agency about radiation levels that might be excessive or pose a risk to either TSA screeners or members of the traveling public.

The Transportation Security Administration is a top-heavy, intrusive bureaucracy that is ineffective in protecting the nation’s skies from terrorists, House Republicans said Wednesday during the week of its 10th anniversary. “We’ve spent nearly $60 billion funding TSA, and travelers are no safer today than they were before 9/11,” said Rep. Paul Broun (R-Ga.), a member of the House Homeland Security Committee, who joined House Transportation and Infrastructure Chairman John Mica in calling for reforms.
