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.

Canadian Copyright Lobby Fights Anti-Spyware Legislation
An anonymous reader writes "New Canadian anti-spam and anti-spyware legislation is scheduled for a key vote on Monday. Michael Geist reports that the copyright lobby has been pushing to remove parts of the bill that would take away exceptions which currently allow spyware to be installed without authorization. 'The copyright lobby is deeply concerned that this change will block attempts to track possible infringement through electronic means.' There have also been proposals to extend the exemptions granted to telecom providers to include the installation of programs without the user's express consent, which Geist says will 'leave the door open to private, surreptitious surveillance.'"Read more of this story at Slashdot.

Scientists Write Memories Directly Into Fly Brains
TheClockworkSoul writes "Researchers at the University of Oxford have devised a way to write memories onto the brains of flies, revealing which brain cells are involved in making bad memories. The researchers said that in flies, just 12 brain cells were responsible for what is known as 'associative learning.' They modified these neurons by adding receptors for ATP, so that the cells activate in the presence of the chemical, but since ATP isn't usually found floating around a fly's brain, the flies generally behave just like any other fly. Most interestingly, however, is that the scientists then injected ATP into the flies' brains, in a form that was locked inside a light-sensitive chemical cage. When they shined a laser on the fly brains, the ATP was released, and the 'associative learning' cells were activated. The laser flash was paired with an odor, effectively giving the fly a memory of a bad experience with the odor that it never actually had, such that it then avoided the odor in later experiments. The researchers describe their findings in the journal Cell."Read more of this story at Slashdot.

Open Source Effort To Codify America's "Operating System" Online
Rubinstien writes "O'Reilly Radar is reporting on an effort to produce Law.gov, 'America's Operating System, Open Source.' The group Public.Resource.Org seeks to 'create a solid business plan, technical specs, and enabling legislation for the federal government to create Law.gov. [They] envision Law.gov as a distributed, open source, authenticated registry and repository of all primary legal materials in the United States.' According to its new website, 'Law.gov would be similar to Data.gov, providing bulk data and feeds to commercial, non-commercial, and governmental organizations wishing to build web sites, operate legal information services, or otherwise use the raw materials of our democracy.'"Read more of this story at Slashdot.
