Wikipedia Breeds Unwitting Trust (Says IT Professor) 441

kingston writes ""As I say to my students 'if you had to have brain surgery would you prefer someone who has been through medical school, trained and researched in the field, or the student next to you who has read Wikipedia'?" So says Deakin University associate professor of information systems, Sharman Lichtenstein, who believes Wikipedia, where anyone can edit a page entry, is fostering a climate of blind trust among people seeking information. Professor Lichtenstein says the reliance by students on Wikipedia for finding information, and acceptance of the practice by teachers and academics, was "crowding out" valuable knowledge and creating a generation unable to source "credible expert" views even if desired. "People are unwittingly trusting the information they find on Wikipedia, yet experience has shown it can be wrong, incomplete, biased, or misleading," she said. "Parents and teachers think it is [okay], but it is a light-weight model of knowledge and people don't know about the underlying model of how it operates.""

A Virus that Attacks Brain Cancer 131

Ponca City, We Love You writes "In the past few years, scientists have looked to viruses as potential allies in fighting cancer. Now researchers at Yale University have found a virus in the same family as rabies that effectively kills an aggressive form of human brain cancer in mice. Using time-lapse laser imaging, the team watched vesicular stomatitis virus (VSV) rapidly home in on brain tumors, selectively killing cancerous cells in its path, while leaving healthy tissue intact. 'A metastasizing tumor is fairly mobile, and a surgeon's knife can't get out all of the cells,' says Anthony Van den Pol, lead researcher and professor of neurosurgery and neurobiology at Yale. 'A virus might be able to do that, because as a virus kills a tumor cell, it could also replicate, and you could end up with a therapy that's self-amplifying.' It's not yet clear why VSV is such an effective tumor killer, although Van den Pol has several theories. One possible explanation may involve a tumor's weak vascular system. Vessels that supply blood to tumors tend to be leaky, allowing a virus traveling through the bloodstream to cross an otherwise impermeable barrier into the brain, directly into a tumor."

Scientists Find Believing Can Be Seeing 169

Ponca City, We Love You writes "Scientists at University College London have found the link between what we expect to see, and what our brain tells us we actually saw revealing that the context surrounding what we see is all important — sometimes overriding the evidence gathered by our eyes and even causing us to imagine things which aren't really there. A vague background context is more influential and helps us to fill in more blanks than a bright, well-defined context. This may explain why we are prone to 'see' imaginary shapes in the shadows when the light is poor. "Illusionists have been alive to this phenomenon for years," said Professor Zhaoping. "When you see them throw a ball into the air, followed by a second ball, and then a third ball which 'magically' disappears, you wonder how they did it. In truth, there's often no third ball — it's just our brain being deceived by the context, telling us that we really did see three balls launched into the air, one after the other." The original research paper is available on PLOS, the open-access, peer-reviewed journal."

Will The Next Generation of Spacecraft Land In the Water? 318

Reservoir Hill writes "Work is progressing on the design of the new Orion Crew Exploration Vehicle (CEV), the next generation of NASA spacecraft that will take humans to the International Space Station, back to the Moon, and hopefully on to Mars. One major question about the spacecraft has yet to be answered. On returning to Earth, should the CEV land in water or on terra firma? After initial studies, the first assessment by NASA and the contractor for the CEV, Lockheed Martin, was that landing on land was preferred in terms of total life cycle costs for the vehicles. Getting the CEV light enough for the Ares rockets to be able to launch it, and therefore eliminating the 1500 lb airbags for landing has its appeal. A splashdown in water seems to be favored."

Did SCO Get Linux-mob Justice? 320

An anonymous reader writes "According to Fortune's legal blogger Roger Parloff, "once in awhile a judicial ruling comes down that's so wrong at such a basic level that you're just left scratching your head". He claims that Judge Kimball's "102-page ruling (about SCO) was greeted with widespread rejoicing and I-told-you-so's", but "the problem is not that Judge Kimball's view of the facts is wrong". Was the ruling unfair?"

Has Wikipedia Peaked? 484

An anonymous reader writes "After more than a year with no official statistics, an independent analysis reported Wednesday showed that activity in Wikipedia's community has been declining over the last six months. Editing is down 20% and new account creation is down 30%. After six years of rapid growth and more than 2 million articles, is Wikipedia's development now past its peak? Are Wikipedians simply running out of things to write about, or is the community collapsing under the weight of external vandalism and internal conflicts? A new collection of charts and graphs help to tell the tale."

Iowa Antitrust Case Costs Microsoft $255M 96

The judge in charge has approved the payout for the case, which was settled seven months ago. Iowa citizens will get up to $179 million in refunds and the attorneys will get $75 million, $8 million of which covers expenses. There's another $1 million in there for legal aid. Individual consumers pocket very little: they can file for $16 for each copy of Windows or MS-DOS purchased over a 12-year period, and $29 for Office. Such a payout would serve as a deterrent only if all 50 states had sued and won similar amounts. Alone it's a slap on the wrist.

How Would You Refocus Linux Development? 821

buddyglass writes "The majority of Slashdot readers are no doubt appreciative of Linux in the general sense, but I suspect we all have some application or aspect of the platform that we wish were more stable, performant, feature-rich, etc. So my question is: if you were able to devote a 'significant' number of resources (read: high-quality developers) to a particular app or area of the kernel, and were able to set the focus for those resources (stability, performance, new features, etc.), what application or kernel area would you attempt to improve, and what would aspect you focus on improving?"

Does Comcast Hate Firefox? 676

destinyland writes "Comcast is the largest ISP in America. And they're requiring Internet Explorer for installations — even if you're using a Mac. The Comcast homepage even specifies that the page is optimized for IE 5.5 (which was released in 2000), and 'is not optimized for Firefox browsers and Macs.' With 13 million subscribers, you'd think they could spring for a web developer who could handle multiple browsers. (From the last line of the article: 'I'm afraid to ask how Comcast handles Linux...')"
