Anonymongoose writes "A researcher at Brookhaven National Lab reckons it could be just a few years before computers can pass through the uncanny valley. The article refers to this as a 'Graphics Turing Test': 'a computer can be considered intelligent if it can create an artificial world capable of fooling a person into believing it is the real thing.' Michael McGuigan has been performing some interesting experiments using Brookhaven's Blue Gene/L supercomputer and has shown that it can produce realistic lighting effects in real time. McGuigan's original research paper (pdf) is available online."

Invisible Pink Unicorn writes "Engineers at the University of California, Riverside have found semiconducting nanotubes produced by living bacteria — a discovery that could help in the creation of a new generation of nanoelectronic devices. This is the first time nanotubes have been shown to be produced by biological rather than chemical means. In a process that is not yet fully understood, the bacterium secretes polysacarides that seem to produce the template for the arsenic-sulfide nanotubes. These nanotubes behave as metals with electrical and photoconductive properties useful in nanoelectronics. The article abstract is available from the Proceedings of the National Academy of Sciences."

Via Joystiq, the news at the Red vs. Blue site that the 100th episode will be their last. Despite the 04/01 posting date of the announcement, it looks like the reality is that there are only a handful of episodes of the Blood Gulch Chronicles left. "One hundred is a great number, and it seems like the perfect place to call it a show. I am sure you have some questions about our plans for the series and beyond. We will be talking about all of that in the weeks and months to come, but I want to use this time to thank all of you for nearly half a decade of support. For now, it's back to work. From the recent developments in the storyline, you may have noticed some loose ends coming together and we have a lot to wrap up in the last seven videos. We hope you will love them as much as the first seven or the middle seven or whatever it was that initially drew you to the world of Red vs Blue." It's always great to see a series go out on a high note, and one can only hope that the folks at RoosterTeeth plan to work on new projects in the future.
