An anonymous reader writes to tell us that a company has demonstrated a new form of wireless communication that uses light instead of radio waves. "Its inventor, St. Cloud resident John Pederson, says visible-light embedded wireless data communication is the next step in the evolution of wireless communications, one that will expand the possibilities in phone and computer use. The connection provides Web access with almost no wiring, better security and with speeds more than eight times faster than cable."

Lumpy writes "I am giving several new PC's to a local charity that will be giving them to needy kids this Xmas. They are not powerful, basically baseline Dells that have Intel graphics and Celeron, but more than enough to do homework and other studies on. They are going out with XP on them, an Ubuntu CD, and a bunch of OSS software like OO.o and the others. I would like to include some games for the kids. Strategy, fun, etc. Great freeware games that are fun to play. What would be the best games that a 13-16 year old will like to play that are free and legal to give away, and will run on this lower-end hardware?"

It seems that Sky Captain and the World of Tomorrow may not have been completely off the mark. According to Venture Beat, Airship Ventures has raised capital sufficient to build their first Zeppelin NT (Microsoft Windows reference purely coincidental). The airship will offer rides for up to 12 passengers out of the old Navy Blimp hangars at Moffett Field in Silicon Valley. Airship Ventures notes that airships are already flying safely in Japan and Germany, so now the US will have its chance. Rides will cost from $250 to $500 per person. Esther Dyson is one of the investors.

esocid alerts us to news out of the University of Michigan, where physics researchers have found a way to focus microwaves to a point 20 times smaller than their wavelength using a new 'superlens'. Such resolution was thought to be impossible until recent years, and it could bring about the capability to transfer power wirelessly. "No matter how powerful a conventional lens, it cannot focus light down to more than about half its wavelength, the 'diffraction limit'. This limits the amount of data that can be stored on a CD, and the size of features on computer chips. The new lens is a 127-micrometer-thick plate of teflon and ceramic with a copper topping. 'The beauty of these is that they're planar,' Grbic says, 'they're easy to fabricate.' The lenses can be made through a single step of photolithography, the process used to etch computer chips."

esocid sends us to the European Space Agency's site for news of a new discovery that appears to resolve the long-standing mystery surrounding Omega Centauri, the largest and brightest globular cluster in the sky. The object is 17,000 light-years distant and is located just above the plane of the Milky Way. Seen from a dark rural area in the southern hemisphere, Omega Centauri appears almost as large as the full moon. What the researchers discovered is a black hole of 40,000 solar masses in the cluster's center. From the press release: "Images obtained with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope and data obtained by the GMOS spectrograph on the Gemini South telescope in Chile show that Omega Centauri appears to harbor an elusive intermediate-mass black hole in its center... Exactly how Omega Centauri should be classified has always been a contentious topic. It was first listed in Ptolemy's catalog nearly two thousand years ago as a single star. Edmond Halley reported it as a nebula in 1677. In the 1830s the English astronomer John Herschel was the first to recognize it as a globular cluster. Now, more than a century later, this new result suggests Omega Centauri is not a globular cluster at all, but a dwarf galaxy stripped of its outer stars. According to scientists, these intermediate-mass black holes could turn out to be baby supermassive black holes."

philetus writes "An article in New Scientist describes a robotic system composed of swarms of electromagnetic modules capable of assuming almost any form that is being developed by the Claytronics Group at Carnegie Mellon. 'The grand goal is to create swarms of microscopic robots capable of morphing into virtually any form by clinging together. Seth Goldstein, who leads the research project at Carnegie Mellon University, Pittsburgh, in the US, admits this is still a distant prospect. However, his team is using simulations to develop control strategies for futuristic shape-shifting, or "claytronic", robots, which they are testing on small groups of more primitive, pocket-sized machines.'"
