Association for Computer Machinery's Conference on Electronic ConferenceSecond Life data offers window into how trends spread Do friends wear the same style of shoe or see the same movies because they have similar tastes, which is why they became friends in the first place? Or once a friendship is established, do individuals influence each other to adopt like behaviors?

SciencePinpointing origin of gamma rays from a supermassive black hole An international collaboration of 390 scientists reports the discovery of an outburst of very-high-energy gamma radiation from the giant radio galaxy Messier 87, accompanied by a strong rise of the radio flux measured from the direct vicinity of its super-massive black hole. The combined results give first experimental evidence that particles are accelerated to extremely high energies of tera electron Volt in the immediate vicinity of a supermassive black hole and then emit the observed gamma rays.

Nanotechnology may increase longevity of dental fillings Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. A Medical College of Georgia researcher hopes a new nanotechnology technique will extend the fillings' longevity.

DNA RepairGenetically engineered mice yield clues to 'knocking out' cancer Researchers from NIST, Oregon Health and Science University and the New York University School of Medicine have demonstrated that deleting two genes in mice responsible for repairing DNA strands damaged by oxidation leads to several types of tumors, providing additional evidence that such stress contributes to the development of cancer. The work may lead to the development of new measurement methods and reference materials for accurate and reproducible assessments of DNA damage and repair. Contact: Michael E. Newman

Journal of Thoracic OncologyResearchers find clear difference in quality, type of lung cancer info available in US and Japan A study published in the July 2009 issue of the Journal of Thoracic Oncology revealed that internet-based lung cancer information was of a higher quality in the United States than in Japan. Dr. Yasushi Goto of the National Cancer Center Hospital in Tokyo and his team of researchers evaluated 150 Web sites, and determined noticeable differences in the quality and type of information on lung cancer available over the Internet in the two countries.

Scientists create first working model of a 2-qubit electronic quantum processor A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology -- similar to that found in computers and cell phones. The new processor is far from conventional, however, in that it uses the potent power of quantum mechanics to bring the dream of quantum computing a small but significant step closer to reality.

Proceedings of the National Academy of SciencesStanford researchers find a quicker, cheaper way to sort isotopes Stanford chemist Richard Zare and his research team have taken a novel approach to building a new device to determine the isotope ratios within a certain substance. It's a new twist on a old procedure used to solve crimes, identify chemicals and date ancient artifacts (think carbon-14 dating). In Zare's device, magnets are replaced with mirrors, and a laser is pointed into the gas produced by burning a sample of the substance.
