Researchers aim to give surgeons 3D maps, directions of human body
While a GPS-style "navigation system" for surgeons may not seem like the best idea to anyone that's ever been led astray by their dash-mounted co-pilot, it apparently seemed like a good enough idea for a group of researchers at the University of Twente in the Netherlands. While they do stretch the metaphor a bit, the group's TLEMsafe system does provide surgeons with a complete 3D map of the lower body, which can actually be personalized for each individual patient, giving surgeons a reference and means to practice before any actual surgery takes place -- and, yes, even an "automated navigation system" during surgery. Coincidentally, some researchers from the University of Colorado have also just announced that they've developed a similar modeling system that would give surgeons 3D views of arteries and let them see any blockages up close. It's even already been tested on patients, while the University of Twente says its system will be ready for clinical trials in about four years' time.
New atomic clock claims title of world's most accurate
You may have thought that the previous world's most accurate clock was good at keeping time, but it's apparently nothing compared to this new strontium atomic clock developed by scientists at the University of Colorado, which is supposedly more than twice as accurate and just as atomic. To achieve that impressive feat, the scientists made use of the same so-called "pendulum effect" of atoms as before, but took things one step further by holding the atoms in a laser beam and freezing them to almost -273 degrees Celsius, or the temperature at which all matter stops resonating. In clock terms, that translates to about one second lost every 300 million years. Of course, that's still one second too many for the researchers, and they say they "dream of getting an atomic clock with perfect precision." You just know you never want to be late for a meeting with these guys.
Is World of Warcraft a religion?
Just when you thought you had heard it all, MMO gamers are now being called religious zealots. According to Theo Zijderveld, a grad student at the University of Colorado, gamers who experience online worlds "like World of Warcraft and Second Life" are doing so to transcend their physical bodies and "realize a new identity in cyberspace". This is not exactly news to us, but it's the connection to religion that becomes interesting.In his 72-page Master's thesis entitled Cyberpilgrims, Zijderveld cites the four dimensions of religion for his cause: community, ethics, culture and emotion. "The community dimension is present in World of Warcraft as well as in Second Life. People are using their avatar online meet other avatars of real people. Avilion is clearly a community of people with the same interest in the fantasy world. The social markers are clear; the rules of how to dress and how to behave are very explicit. Avatars who do not fit in this picture are (sometimes actively) excluded by the community or by the moderators." At least now your family can't nag you for not going to church enough.
