Believing In Medical Treatments That Don't Work 467

Hugh Pickens writes "David H. Newman, M.D. has an interesting article in the NY Times where he discusses common medical treatments that aren't supported by the best available evidence. For example, doctors have administered 'beta-blockers' for decades to heart attack victims, although studies show that the early administration of beta-blockers does not save lives; patients with ear infections are more likely to be harmed by antibiotics than helped — the infections typically recede within days regardless of treatment and the same is true for bronchitis, sinusitis, and sore throats; no cough remedies have ever been proven better than a placebo. Back surgeries to relieve pain are, in the majority of cases, no better than nonsurgical treatment, and knee surgery is no better than sham knee surgery where surgeons 'pretend' to do surgery while the patient is under light anesthesia. Newman says that treatment based on ideology is alluring, 'but the uncomfortable truth is that many expensive, invasive interventions are of little or no benefit and cause potentially uncomfortable, costly, and dangerous side effects and complications.' The Obama administration's plan for reform includes identifying health care measures that work and those that don't, and there are signs of hope for evidence-based medicine: earlier this year hospital administrators were informed by the Centers for Medicare and Medicaid Services that beta-blocker treatment will be retired as a government indicator of quality care, beginning April 1, 2009. 'After years of advocacy that cemented immediate beta-blockers in the treatment protocols of virtually every hospital in the country,' writes Newman, 'the agency has demonstrated that minds can be changed.'"

Uproar Over Netflix's New Instant Viewer 575

almechist writes "Many Netflix customers are up in arms over the new instant-watch player powered by Microsoft's Silverlight. The official Netflix blog is full of complaints from users who decry not only the new player's quality but also the way it's being distributed, with many claiming they were deceived into downloading it. Once you opt for the new player, the old Windows Media based player won't function, not on any computer associated with the account. The new player is supposedly still beta, but NF members are strongly encouraged (some say tricked) by NF into the so-called 'upgrade,' which is permanent — there is no way to opt out. The marked decrease in video quality seen by those who have switched is perhaps not surprising, since the old player could utilize bit streams up to twice as fast as the new one, but this information is nowhere given out by NF. So far NF has been answering all complaints with variations on 'tough luck pal, you're stuck with it,' but many customers are so disgusted they're ready to cancel their NF membership. This could be a public relations disaster in the making for Netflix."

Space Based Solar Power Within a Decade? 371

Nancy Atkinson writes "A new company, Space Energy, Inc., says they have developed what they call a 'rock-solid business platform' and they should be able to provide commercially available space based solar power within a decade. 'Although it's a very grandiose vision, it makes total sense,' Space Energy's Peter Sage told Universe Today. 'We're focused on the fact that this is an inevitable technology and someone is going to do it. Right now we're the best shot. We're also focused on the fact that, according to every scenario we've analyzed, the world needs space based solar power, and it needs it soon, as well as the up-scaling of just about every other source of renewable energy that we can get our hands on.'"

Demo of Spatially Aware Blocks 109

Chris Anderson writes "This 5-min demo just posted from last week's TED — got a big crowd reaction. It's a new technology coming out of MIT, about to be commercialized. Siftables have been seen before, but not like this. They're toy blocks/tiles that are spatially aware and interact with each other in very cool ways. Initial use may be as toys, but there's big potential for new paradigm of spatially-aware physical mini computers."

Washington State Wants DNA From All Arrestees 570

An anonymous reader writes in to say that "Suspects arrested in cases as minor as shoplifting would have to give a DNA sample before they are even charged with a crime if a controversial proposal is approved by the Legislature. "It is good technology. It solves crimes," claims Don Pierce, executive director of the Washington Association of Sheriffs and Police Chiefs. Under the bill, authorities would supposedly destroy samples and DNA profiles from people who weren't charged, were found not guilty or whose convictions were overturned. Others believe that this is just another step in the process to build a national DNA database with everyone in it."

Snakelike Robot To Treat Soldiers During Battle 130

Al writes "Technology Review has an article about a snake-like robotic arm that could soon be used to treat injured soldiers as they lie on the battlefield. Developed by researchers at Carnegie Mellon University, the snakebot attaches to a stretcher and is controlled remotely using a joystick, allowing a doctor to assess a soldier's injuries as the bullets fly by. In future, the robotic arm will be fitted with sensors allowing it to measure vital signs and probe for internal bleeding. Here's a brief video of a prototype arm in action. The arm will become part of the US military's high-tech stretcher, called the Life Support for Trauma and Transport system. This is essentially a portable intensive-care unit, with a ventilator, defibrillator, and other physiological monitors, and it's currently being used in areas of Iraq and Afghanistan."

Could Fake Phishing Emails Help Fight Spam? 296

Glyn Moody writes "Apparently, the US Department of Justice has been sending out hoax emails to test the security awareness of its staff. How about applying a similar strategy to tackling spam among ordinary users? If fake spam messages offering all the usual benefits, and employing all the usual tricks, were sent out by national security agencies around the world, it would select precisely the people who tend to respond to spam. The agencies could then contact them from a suitably important-looking government address, warning about what could have happened. Some might become more cautious as a result, others will not. But again, it is precisely the latter who are more likely to respond to further fake spam messages in the future, allowing the process to be repeated as often as necessary. The system would be cheap to run — spam is very efficient — and could use the latest spam as templates."

Cox Communications and "Congestion Management" 282

imamac writes "It appears Cox Communications is the next in line for throttling internet traffic. But it's not throttling of course; Cox's euphemism is 'congestion management.' From Cox's explanation: 'In February, Cox will begin testing a new method of managing traffic on our high-speed Internet network in our Kansas and Arkansas markets. During the occasional times the network is congested, this new technology automatically ensures that all time-sensitive Internet traffic — such as web pages, voice calls, streaming videos and gaming — moves without delay. Less time-sensitive traffic, such as file uploads, peer-to-peer and Usenet newsgroups, may be delayed momentarily...' Sounds like throttling to me."

Black Holes From the LHC Could Last For Minutes 672

KentuckyFC writes "There is absolutely, positively, definitely no chance of the LHC destroying the planet (or this way either) when it eventually switches on some time later this year. And yet a few niggling doubts are persuading some scientists to run through their figures again. One potential method of destruction is that the LHC will create tiny black holes that could swallow everything in their path, including the planet. Various scientists have said this will not happen because the black holes would decay before they could do any damage. But physicists who have re-run the calculations now say that the mini black holes produced by the LHC could last for seconds, possibly minutes. Of course, the real question is whether they decay faster than they can grow. The new calculations suggest that the decay mechanism should win over and that the catastrophic growth of a black hole from the LHC 'does not seem possible' (abstract). But shouldn't we require better assurance than that?"

A Step Toward an Invisibility Cloak 197

Technology Review has a writeup on the latest advance in the lab towards an invisibility cloak made of metamaterials, described this week in Science. We've been following this technology since the beginning. The breakthrough is software that lets researchers design materials that are both low-loss and wideband. "The cloak that the researchers built works with wavelengths of light ranging from about 1 to 18 gigahertz — a swath as broad as the visible spectrum. No one has yet made a cloaking device that works in the visible spectrum, and those metamaterials that have been fabricated tend to work only with narrow bands of light. But a cloak that made an object invisible to light of only one color would not be of much use. Similarly, a cloaking device can't afford to be lossy: if it lets just a little bit of light reflect off the object it's supposed to cloak, it's no longer effective. The cloak that Smith built is very low loss, successfully rerouting almost all the light that hits it."

South Carolina Seeking To Outlaw Profanity Screenshot-sm 849

MBGMorden writes "It looks like in an act that defies common sense, a bill has been introduced in the South Carolina State Senate that seeks to outlaw the use of profanity. According to the bill it would become a felony (punishable by a fine up to $5000 or up to 5 years in prison) to 'publish orally or in writing, exhibit, or otherwise make available material containing words, language, or actions of a profane, vulgar, lewd, lascivious, or indecent nature.' I'm not sure if 'in writing' could be applied to the internet, but in any event this is scary stuff."

A Cheap, Distributed Zero-Day Defense? 116

coondoggie writes "Shutting down zero-day computer attacks could be carried out inexpensively by peer-to-peer software that shares information about anomalous behavior, say researchers at the University of California at Davis.The software would interact with existing personal firewalls and intrusion detection systems to gather data about anomalous behavior, says Senthil Cheetancheri, the lead researcher on the project he undertook as a grad student at UC Davis from 2004 to 2007. He now works for SonicWall."

Internet Not Really Dangerous For Kids After All 445

Thomas M Hughes writes "We're all familiar with the claim that it's horribly dangerous to allow our children on to the Internet. It's long been believed that the moment a child logs on to the Internet, he will experience a flood of inappropriate sexual advances. Turns out this isn't an accurate representation of reality at all. A high-profile task force representing 49 state attorneys general was organized to find a solution to the problem of online sexual solicitation. But instead the panel has issued a report (due to be released tomorrow) claiming that 'Social networks are very much like real-world communities that are comprised mostly of good people who are there for the right reasons.' The report concluded that 'the problem of child-on-child bullying, both online and offline, poses a far more serious challenge than the sexual solicitation of minors by adults.' Turns out the danger to our children was all just media hype and parental anxiety." Those who have aggressively pushed the issue of the dangerous Internet, such as Connecticut's attorney general Richard Blumenthal, are less than happy with the report.

In-Depth With the Windows 7 Public Beta 785

Dozer writes "With the Windows 7 public beta out, Ars Technica has an in-depth look at the release. There's praise for Windows 7's UI changes and polish as well much-needed changes to UAC, but also a warning that those who have problems with Vista won't like Windows 7 much better. 'If you couldn't stand Vista's UI (whether it's because you didn't like Explorer, Aero, Control Panel, UAC, or anything else), Windows 7 is unlikely to do much to help, as it builds on the same UI. If Vista's hardware demands were too steep, Windows 7 will likely cause you the same grief, as its hardware demands match. And if Vista didn't work with a program or device you need to use, Windows 7 will offer no salvation, as its compatibility is virtually identical.'"
