Immune System Killer Mechanism Identified 88

traveller.ct writes "Researchers from Melbourne and London have identified the mechanism by which the immune system destroys malignant cells. The notion of killer cells puncturing a malignant cell to inject toxic enzymes has been understood for over a century, but now, using the Australian Synchrotron, researchers have identified the protein which is responsible for forming a pore in the malignant cell: perforin. Perforin resembles the cellular weaponry employed by bacteria such as anthrax, but may have been appropriated by our immune system in our evolutionary past to fight against them. The researchers are now investigating ways to boost perforin for more effective cancer protection and therapy for acute diseases such as cerebral malaria."

Facebook Buys a Private File Sharing Service 87

angry tapir writes "Facebook has purchased most of drop.io, an online content-sharing service, but the social-networking giant sounds more interested in acquiring the company's developers than its technology. Drop.io is a service that lets users create a 'drop' where they can share documents, videos and other digital content. The user can set a time for how long the drop will exist, decide who can view the content, set permissions for who can alter the content and share content in a variety of ways, including on Facebook."

VLC Developer Takes a Stand Against DRM Enforcement 717

jamie writes "The GPL gives Apple permission to distribute this software through the App Store. All they would have to do is follow the license's conditions to help keep the software free. Instead, Apple has decided that they prefer to impose Digital Restrictions Management (DRM) and proprietary legal terms on all programs in the App Store, and they'd rather kick out GPLed software than change their own rules."
