Here is Bruce Schneier's take on the subject.

"... assuming that the radiation in a backscatter X-ray is about a hundredth the dose of a dental X-ray, we find that a backscatter X-ray increases the odds of dying from cancer by about 16 ten millionths of one percent. That suggests that for every billion passengers screened with backscatter radiation, about 16 will die from cancer as a result.

Given that there will be 600 million airplane passengers per year, that makes the machines deadlier than the terrorists."

Earliest Americans Arrived In Waves, DNA Study Finds 131

Posted by samzenpus from the where-are-you-from? dept.
NotSanguine writes "Nicholas Wade of the New York Times has written an article about a new DNA study that suggests the earliest Americans arrived in three waves, not one. 'North and South America were first populated by three waves of migrants from Siberia rather than just a single migration, say researchers who have studied the whole genomes of Native Americans in South America and Canada. Some scientists assert that the Americas were peopled in one large migration from Siberia that happened about 15,000 years ago, but the new genetic research shows that this central episode was followed by at least two smaller migrations from Siberia, one by people who became the ancestors of today's Eskimos and Aleutians and another by people speaking Na-Dene, whose descendants are confined to North America.' The study, published online (paywalled), investigated geographic, linguistic and genetic diversity in native American populations."

Submission + - DirectTV Drops Viacom Channels (examiner.com)

Submitted by Anonymous Coward
An anonymous reader writes: DirectTV has dropped all of Viacom's channels. This includes channels such as MTV, Comedy Central, and Nickelodeon. The drop is reported to be over a carrier fee dispute. It appears programming content can magically disappear from satellite too and not just from streaming services. I guess pirating and physical media is the only way to make sure the content we pay for doesn't disappear.

Submission + - OS X 10.8 (Mountain Lion) Won't Support Some 64-bit Macs with Older GPUs (hothardware.com)

Submitted by
MojoKid
MojoKid writes: "Apple is pitching Mac OS X 10.8 (Mountain Lion) as the cat's meow with over 200 new features "that add up to an amazing Mac experience," but that only applies if you're rocking a compatible system. Some older Mac models, including ones that are 64-bit capable, aren't invited to the Mountain Lion party, and it's likely because of the GPU. It's being reported (unofficially) that an updated graphics architecture intended to smooth out performance in OS X's graphics subsystem is the underlying issue. It's no coincidence, then, that the unsupported GPUs happen to be ones that were fairly common back before 64-bit support became mainstream."

How many people are remembering to consider their phones as possibly their "most-used personal computer"?

Who the hell uses their phone more than their PC?

I know a few that probably do, like my overly talkative sister. But for myself, my phone isn't even in the top three. I'm probably an exception, since I use my phone primarily as an XBMC remote.
