Um No?
A Democracy is 51% or more can change everything.
A Republic has a core of laws that are not changeable by simple majority vote.
I realize that people are using the two interchangeably (out of ignorance or perhaps trying to move the Overton window) but they are NOT the same. True Democracy is a very short lived and violent form of government. In history Republics tend to be stable forms of government.
At the moment the US is a representive republic I am aware some people ignorant of what they are asking for have been clamoring for a true democracy. I very much hope they never get their way.

What US Health Care Needs 584

Medical doctor and writer Atul Gawande gave the commencement address recently at Stanford's School of Medicine. In it he lays out very precisely and in a nonpartisan way what is wrong with the institution of medical care in the US — why it is both so expensive and so ineffective at delivering quality care uniformly across the board. "Half a century ago, medicine was neither costly nor effective. Since then, however, science has... enumerated and identified... more than 13,600 diagnoses — 13,600 different ways our bodies can fail. And for each one we've discovered beneficial remedies... But those remedies now include more than six thousand drugs and four thousand medical and surgical procedures. Our job in medicine is to make sure that all of this capability is deployed, town by town, in the right way at the right time, without harm or waste of resources, for every person alive. And we're struggling. There is no industry in the world with 13,600 different service lines to deliver. ... And then there is the frightening federal debt we will face. By 2025, we will owe more money than our economy produces. One side says war spending is the problem, the other says it's the economic bailout plan. But take both away and you've made almost no difference. Our deficit problem — far and away — is the soaring and seemingly unstoppable cost of health care. ... Like politics, all medicine is local. Medicine requires the successful function of systems — of people and of technologies. Among our most profound difficulties is making them work together. If I want to give my patients the best care possible, not only must I do a good job, but a whole collection of diverse components must somehow mesh effectively. ... This will take science. It will take art. It will take innovation. It will take ambition. And it will take humility. But the fantastic thing is: This is what you get to do."

Matter-Antimatter Bias Seen In Fermilab Collisions 304

ubermiester writes "The New York Times is reporting that scientists at Fermilab have found evidence of a very small (about 1%) average difference between the amount of matter/antimatter produced in a series of particle collisions. Quoting: '[T]he team, known as the DZero collaboration, found that the fireballs produced pairs of ... muons ... slightly more often than they produced pairs of anti-muons. So the miniature universe inside the accelerator went from being neutral to being about 1 percent more matter than antimatter.' This finding invites theorists to explain why there is so much more matter than antimatter in the universe, when the Standard Model suggests that there should be equal amounts of each." Here is the paper as submitted to Physical Review (PDF). The DZero team is looking forward to getting detailed data from the LHC once it ramps up operationally.

Commercial Quantum Cryptography System Hacked 117

KentuckyFC writes "Any proof that quantum cryptography is perfect relies on idealized assumptions that don't always hold true in the real world. One such assumption is related to the types of errors that creep into quantum messages. Alice and Bob always keep a careful eye on the level of errors in their messages because they know that Eve will introduce errors if she intercepts and reads any of the quantum bits in a message. So a high error rate is a sign that the message is being overheard. But it is impossible to get rid of errors entirely, so Alice and Bob have to tolerate a small level of error. This level is well known. Various proofs show that if the quantum bit error rate is less than 20 percent, then the message is secure. However, these proofs assume that the errors are the result of noise from the environment. Now, physicists have come up with an attack based on the realization that Alice also introduces errors when she prepares the required quantum states to send to Bob. This extra noise allows Eve to intercept some of the quantum bits, read them and then send them on, in a way that raises the error rate to only 19.7 percent. In this kind of 'intercept and resend attack,' the error rate stays below the 20 percent threshold and Alice and Bob are none the wiser, happily exchanging keys while Eve listens in unchallenged. The physicists say they have successfully used their hack on a commercial quantum cryptography system from the Geneva-based startup ID Quantique."

Scientists Question Safety of New Airport Scanners 357

An anonymous reader sends this quote from a story at NPR about the accelerated deployment of new scanning machines at airports: "Fifty-two of these state-of-the-art machines are already scanning passengers at 23 US airports. By the end of 2011, there will be 1,000 machines and two out of every three passengers will be asked to step into one of the new machines for a six-second head-to-toe scan before boarding. About half of these machines will be so-called X-ray back-scatter scanners. They use low-energy X-rays to peer beneath passengers' clothing. That has some scientists worried. ... The San Francisco group thinks both the machine's manufacturer, Rapiscan, and government officials have miscalculated the dose that the X-ray scanners deliver to the skin — where nearly all the radiation is concentrated. The stated dose — about .02 microsieverts, a medical unit of radiation — is averaged over the whole body, members of the UCSF group said in interviews. But they maintain that if the dose is calculated as what gets deposited in the skin, the number would be higher, though how much higher is unclear."

ACLU Sues To Protect Your Right To Swear 698

The ACLU is suing the police in Pennsylvania for issuing tickets to people who swear. They argue that it is every American's constitutional right to drop an F-bomb. From the article: "'Unfortunately, many police departments in the commonwealth do not seem to be getting the message that swearing is not a crime,' said Marieke Tuthill of the ACLU of Pennsylvania. 'The courts have repeatedly found that profanity, unlike obscenity, is protected speech.'" This is a big f*cking deal.

Seagate Confirms 3TB Hard Drive 467

Stoobalou writes "After a few weeks of rumours, Seagate's senior product manager Barbara Craig has confirmed that the company is announcing a 3TB drive later this year, but the move to 3TB of storage space apparently involves a lot more work than simply upping the areal density. The ancient foundations of the PC's three-decade legacy has once again reared its DOS-era head, revealing that many of today's PCs are simply incapable of coping with hard drives that have a larger capacity than 2.1TB."

Cheap Cancer Drug Finally Tested In Humans 363

John Bayko writes "Mentioned on Slashdot a couple of years ago, the drug dichloroacetate (DCA) has finally finished its first clinical trial against brain tumors in humans. Drug companies weren't willing to test a drug they could not patent, so money was raised in the community through donations, auctions, and finally government support, but the study was still limited to five patients. It showed extremely positive results in four of them. This episode raises the question of what happens to all the money donated to Canadian and other cancer societies, and especially the billions spent buying merchandise with little pink ribbons on it, if not to actual cancer research like this."

Supermassive Black Hole Is Thrown Out of Galaxy 167

DarkKnightRadick writes "An undergrad student at the University of Utrecht, Marianne Heida, has found evidence of a supermassive black hole being tossed out of its galaxy. According to the article, the black hole — which has a mass equivalent to one billion suns — is possibly the culmination of two galaxies merging (or colliding, depending on how you like to look at it) and their black holes merging, creating one supermassive beast. The black hole was found using the Chandra Source Catalog (from the Chandra X-Ray Observatory). The direction of the expulsion is also possibly indicative of the direction of rotation of the two black holes as they circled each other before merging."

Why would downloading the game 4 or 5 times even count? It's not like there's some global counter out there that says "# of times pirated" as much as the game publishers would like you to believe.

First choice - don't buy the game and/or buy other games. Second choice - pirate. Not necessarily condoned by yours truly, but eh, it's a choice.
