Submission + - Purported Relativity Paradox Resolved (sciencemag.org)

sciencehabit writes: A purported conflict between the century-old theory of classical electrodynamics and Einstein's theory of special relativity doesn't exist, a chorus of physicists says. Last April, an electrical engineer claimed that the equation that determines the force exerted on an electrically charged particle by electric and magnetic fields—the Lorentz force law—clashes with relativity, the theory that centers on how observers moving at a constant speed relative to one another will view the same events. To prove it, he concocted a simple "thought experiment" in which the Lorentz force law seemed to lead to a paradox. Now, four physicists independently say that they have resolved the paradox.

angry tapir writes "Pope Benedict XVI Monday gave his blessing to social networking, urging Catholic Internet users to adopt a respectful Christian netiquette when spreading the Gospel online.

Professor Ditches Grades For XP System 311

schliz writes "Like in World of Warcraft, students of Indiana University's game design classes start as Level 1 avatars with 0 XP, and progress by completing quests solo, as guilds, or in 'pick up groups.' Course coordinator Lee Sheldon says students are responding with 'far greater enthusiasm,' and many specifics of game design could also be directly applied to the workforce. These included: clearly defining goals for workers; providing incremental rewards; and balancing effort and reward."

Stem Cell Treatment To Cure the Most Common Cause of Blindness 126

The Times Online reports that researchers from the Institute of Ophthalmology at University College London and Moorfields eye hospital have developed stem cell therapy that can treat age-related macular degeneration (AMD), the most common cause of blindness. They are currently moving the treatment through the regulatory approval process, and clinical trials are expected to start within two years. Quoting: "Under the new treatment, embryonic stem cells are transformed into replicas of the missing cells. They are then placed on an artificial membrane which is inserted in the back of the retina. ... [Professor Pete Coffey, director of the London Project to Cure Blindness] said the treatment would take 'less than an hour, so it really could be considered as an outpatient procedure. We are trying to get it out as a common therapy.'
