Facial Bones Grown From Fat-Derived Stem Cells
TheClockworkSoul sends in an article up at Scientific American, from which we quote: "Stem cells so far have been used to mend tissues ranging from damaged hearts to collapsed tracheas. Now the multifaceted cells have proved successful at regrowing bone in humans. In the first procedure of its kind, doctors at Cincinnati Children's Hospital Medical Center replaced a 14-year-old boy's missing cheekbones — in part by repurposing stem cells from his own body. To create the new bones, which have become part of the patient's own skull structure and have remained securely in place for four and a half months, the medical team used a combination of fat-derived stem cells, donated bone scaffolds, growth factors, and bone-coating tissue. The technique, should it be approved for widespread use, could benefit some seven million people in the US who need more bone — everyone from cancer patients to injured war veterans."Read more of this story at Slashdot.
How To List FOSS Experience On Your Resume
maximus1 writes "If you're selling skills gained in an open source project, you have additional opportunities to shine, say experts in this ITWorld article. But what is the best way to explain your FOSS experience? 'Someone stands out because of how they talk about the project, says Zack Grossbart, author of The One Minute Commute. His advice is to describe the project and discuss your contributions in detail: 'If you were a committer, what did you do to earn that status? What features did you work on? Did you design new areas, or just implement predefined functions? Did you lead meetings? Define new architecture? Set the project direction?' If the FOSS experience is part of your background but not a shining beacon or job equivalent, it's common to list it under 'other experience.' Andy Lester, author of Land The Tech Job You Love, says: 'Think of each project as a freelance job that you've worked on. Just as different freelance gigs have varying sizes and scopes, so too does each project to which you contribute. The key is to not lump all your projects under one "open source work" heading.' Good examples are worth a thousand words. Grossbart offers up his resume as a sound but not perfect example (PDF) that includes open source experience. (His article on how to format your resume might also be of interest.)"Read more of this story at Slashdot.
Giant Ribbon Discovered At Edge of Solar System
beadwindow writes "NASA's IBEX (Interstellar Boundary Explorer) spacecraft has made the first all-sky maps of the heliosphere and the results have taken researchers by surprise. The maps are bisected by a bright, winding ribbon of unknown origin: 'This is a shocking new result,' says IBEX principal investigator Dave McComas of the Southwest Research Institute. 'We had no idea this ribbon existed — or what has created it. Our previous ideas about the outer heliosphere are going to have to be revised.' Another NASA scientist notes, '"This ribbon winds between the two Voyager spacecraft and was not observed by either of them.'"Read more of this story at Slashdot.
On the Efficacy of Flu Vaccine
The Atlantic is running a major article questioning the received wisdom about flu vaccines and antivirals, for both seasonal flu and H1-N1. "When Lisa Jackson, a physician and senior investigator with the Group Health Research Center, in Seattle, began wondering aloud to colleagues if maybe something was amiss with the estimate of 50 percent mortality reduction for people who get flu vaccine, the response she got sounded more like doctrine than science. 'People told me, "No good can come of [asking] this,"' she says... Nonetheless, in 2004, Jackson and three colleagues set out to determine whether the mortality difference between the vaccinated and the unvaccinated might be caused by a phenomenon known as the 'healthy user effect.' Jackson's findings showed that outside of flu season, the baseline risk of death among people who did not get vaccinated was approximately 60 percent higher than among those who did, lending support to the hypothesis that on average, healthy people chose to get the vaccine, while the 'frail elderly' didn't or couldn't. In fact, the healthy-user effect explained the entire benefit that other researchers were attributing to flu vaccine, suggesting that the vaccine itself might not reduce mortality at all."

MS's "Lifeblogging" Camera Enters Mass Production
holy_calamity writes "Remember Microsoft's camera to be slung around the necks of people with Alzheimer's to help them recall where they'd been? A version of this device will now be mass-produced by a UK firm, Vicon, which obtained a license from Microsoft to manufacture the camera. It is worn around the neck and takes an image every thirty seconds, or in response to its light sensor, accelerometer, or body-heat sensor indicating that something of interest may be happening. Until now only a few hundred had been made for research, which showed they can genuinely help people with memory problems. The new version will be marketed to Alzheimer's researchers this winter, and to consumers for 'lifelogging' beginning in 2010."Read more of this story at Slashdot.
Arrested IBM Exec Goes MIA On the Web
theodp writes "Among those charged in the largest hedge-fund insider trading case in US history was IBM Sr. VP Robert W. Moffat, the heir apparent to IBM CEO Sam Palmisano and the guy behind Big Blue's 'workforce rebalancing' and the sale of IBM's PC unit to Lenovo. IBM's not talking about the incident, but it's interesting that Moffat's bio is MIA at IBM.com ('Biography you tried to access does not exist.'), and his Smarter Planet video can no longer be found ('This video has been removed by the user.') at IBM's YouTube Channel. Do you need approval from the Feds before tidying up after someone who's under investigation? BTW, if stories and comments appearing in the Times Herald-Record and Poughkeepsie Journal are any indication, Moffat may want to avoid a local jury trial. 'I have talked to a few IBMers today, and there seems to be a lot of cheering in the halls of IBM over his arrest,' said Lee Conrad of Alliance@IBM."Read more of this story at Slashdot.
The Medical Benefits of Carbon Monoxide
tugfoigel writes with this excerpt from the Boston Globe: "For more than a century, carbon monoxide has been known as a deadly toxin. In an 1839 story, Edgar Allan Poe wrote of 'miraculous lustre of the eye' and 'nervous agitation' in what some believe are descriptions of carbon monoxide poisoning, and today, cigarette cartons warn of its health dangers. But a growing body of research, much of it by local scientists, is revealing a paradox: the gas often called a silent killer could also be a medical treatment. It seems like a radical contradiction, but animal studies show that in small, extremely controlled doses the gas has benefits in everything from infections to organ transplantation."Read more of this story at Slashdot.
The Changing Face of the Console Wars
An article at Gamasutra explores the decisions by Microsoft and Sony to launch significant hardware additions — their respective, upcoming motion-control schemes — in the middle of a console cycle, rather than waiting until the next generations of their systems are ready. It's indicative of a change to the established pattern of console wars; nowadays, it's more about adding features and gadgets to improve existing products than developing entirely new ones. Quoting: "... for Sony and Microsoft, motion controllers are their next-gen consoles. And it's a damn sight easier than launching Xbox 720 or PS4. They can debut these peripherals without needing to engineer completely new boxes for consumers, potentially bundle them over time, and they have a much better chance at getting exclusive games, thanks to the specificity of the hardware (something that's happened a lot for the Wii). Thus, both hardware manufacturers and publishers like EA see these controllers sparking new interest in Xbox 360 and PS3, which will delay the next dreaded console transition for another few years."Read more of this story at Slashdot.
New Nanotech Helps Detect Early-Stage Cancer
CWmike writes "Stanford University researchers have used nanotechnology and magnetics to create a biosensor that they said should be able to detect cancer in its early stages. The sensor, which sits on a microchip, is 1,000 times more sensitive than cancer detectors used clinically today, say scientists at Stanford. The researchers announced this week that the sensors have been effective in finding early-stage tumors in mice, giving them hope that it can be equally successful in detecting elusive cancers in humans. 'In the early stage [of a cancer], the protein biomarker level in blood is very, very low, so you need ultra-sensitive technology to detect it,' said Shan Wang, professor of materials science and engineering at Stanford. 'If you can detect it early, you can have early intervention and you have a much better chance to cure that person.' Wang also noted that the biosensor could be used to determine whether chemotherapy or other cancer treatments are working after only a few days."Read more of this story at Slashdot.
Democrats, Minority Groups Question Net Neutrality Push
uuddlrlrab writes "A group of 72 Democratic lawmakers is the latest to question the US Federal Communications Commission's move to create new net neutrality regulations. Democrats, including US President Barack Obama, have generally supported new rules that would prohibit broadband providers from selectively blocking or slowing Web content, but the group of 72 members of the House of Representatives sent a letter Thursday to FCC Chairman Julius Genachowski, saying they're concerned that new regulations would slow down investment in broadband networks. A coalition of minority groups made their objections known as well, saying, 'We are concerned that some of the proposed regulations on the Internet could, as applied, inhibit the goal of universal access and leave disenfranchised communities further behind.' This follows news from earlier in the week that similar letters were sent by a group of 44 tech companies and a group of 18 Republican senators." It's worth noting that the FCC is receiving letters in support of the net neutrality regulations as well. One such is from a group of internet pioneers, which includes Vint Cerf and Stephen Crocker.Read more of this story at Slashdot.
Kaspersky CEO Wants End To Online Anonymity
Andorin writes "Eugene Kaspersky, CEO of well-known computer security company Kaspersky Labs, is calling for an end to the anonymity of the Internet, and for the creation of mandatory 'Internet passports' for anyone who wishes to browse the Web. Says Kaspersky, 'Everyone should and must have an identification, or internet passport ... the internet was designed not for public use, but for American scientists and the US military. Then it was introduced to the public, and it was wrong ... to introduce it in the same way.' He calls anonymity 'the Internet's biggest security vulnerability' and thinks any country that doesn't follow this regime should be 'cut off.' The EFF objects, and it's likely that they won't be the only ones."Read more of this story at Slashdot.
California Moving Forward With Big-Screen TV Power Restrictions
Hugh Pickens writes "The Los Angeles Times reports that California regulators are poised to pass the nation's first ban on energy-hungry big-screen televisions just as they did with refrigerators, air conditioners and dozens of other products since the 1970s. 'We would not propose TV efficiency standards if we thought there was any evidence in the record that they will hurt the economy,' said Commissioner Julia Levin, who has been in charge of the two-year rule-making procedure. 'This will actually save consumers money and help the California economy grow and create new clean, sustainable jobs.' California's estimated 35 million TVs and related electronic devices account for about 10% of all household electricity consumption, but manufacturers quickly are coming up with new technologies that are making even 50-inch-screen models much more economical to operate. Sets with screens of up to 58 inches would have until the start of 2011 to comply with a minimum efficiency standard, with more stringent rules being introduced two years later. If all TVs met state standards, California could avoid the $600-million cost of building a natural-gas-fired power plant, says Ken Rider, a commission staff engineer. Switching to more-efficient TVs could have an estimated net benefit to the state of $8.1 billion, the commission staff reported."Read more of this story at Slashdot.
Avataritis — On the Abundance of Customizable Game Characters
Martyn Zachary writes "The Slowdown has posted a new critique, 'Avataritis,' that attempts to portray the utilization of character customization as a pandemic, emotional response on behalf of publishers and developers to finding the easiest, most efficient solution to the very unique dilemma presented by the enlarging, widening player base of video games. 'No mechanisms are in place stopping developers from writing and designing heterogeneous yet fully structured, narrative-based computer games with carefully constructed and immutable, unchangeable characters.' The article discusses the emergence and role of gender criticism and research in relation to the recent proliferation of the customizable avatar. The story also dissects the very act of character creation, subsequently aiming to clarify several semantic distortions related to the terminology utilized in character creation, and in turn breaking apart the concepts of relatability and understandability, wholly differentiating the two. The overarching analysis is finally related to examples from the gaming marketplace, where many continue to corroborate apparent falsehoods and misunderstandings in relation to the utilization of the avatar. Ultimately, the writer hopes to dissuade readers, developers and players from believing that written narratives are going away as customization and emergent content are entering video games with full force."Read more of this story at Slashdot.
German Team Wins 2009 Solar Decathlon
An anonymous reader writes "Our team recently competed in the 2009 US Department of Energy Solar Decathlon. The Solar Decathlon is a 2-year competition that challenges university students from 20 US and international teams to design, build, and operate the most attractive and energy-efficient solar-powered house. Objective scores are based on comfort control, appliance performance, net-metering, and home entertainment. Subjective contest scores are determined by juries that weigh the engineering design, architectural design, as well as marketing and communication strategies. Team Germany took 1st place due to a large net production of electricity, while Team California claimed top honors in the Architecture contest. Minnesota won the engineering design section. However, looking beyond the contest winners, the main purpose of the event is to raise awareness about solar technology and sustainable design. As part of this campaign, products used in all 20 homes are listed on the DOE website. The most exciting aspect is that the construction and engineering documents and communication materials from all teams are open-sourced for anyone to use or modify!"Read more of this story at Slashdot.
New Super Mario Bros. Wii Attempts To Bridge Casual/Hardcore Divide
When Nintendo returns to its roots next month by releasing a new, 2-D, side-scrolling Super Mario Bros. game for the Wii, it's trying to do more than simply hop on the retro bandwagon many publishers have ridden in recent months. Speaking at a roundtable discussion in New York this week, Nintendo game designer Shigeru Miyamoto talked about how they're trying to satisfy fans of the series who want challenging gameplay in addition to attracting new or casual players just looking for an entertaining platformer. Quoting: "... you can play the story mode single-player all the way through from beginning to end, and at any point along the way, you can add players from the world map and have up to four players cooperate to complete the levels. And beyond that, there are two dedicated multiplayer modes, one of which is free-for-all, which lets you select the stages from story mode ... so you can easily find the stage you like. And then there’s also a coin battle mode which is a competitive multiplayer mode, in which you’re actually competing for points and you’re getting ranked based on how many points you’ve collected. The free-for-all mode has kind of a similar feel to something like Mario Kart where you just happen to have four people over and you want to sit down and play a quick match in your favorite level."Read more of this story at Slashdot.
