  1. Re:stop the lies on Startup Claims to Make $1/Gallon Ethanol · · Score: 1

    RTFA, their process uses any type of material like corn husks or hay.

  2. One Thing not well-addressed in TFA on GM Says Driverless Cars Will Be Ready By 2018 · · Score: 2, Insightful

    I'm sure designers have taken this all into account, but I'd still be concerned with control systems for pedestrian avoidance, sensors determining whether the small object in front is a newspaper or a rock to be avoided, and predicting behaviors of bicyclists, etc. Sometimes its better to run over a squirrel than break suddenly and risk being rear-ended or swerve around it.

  3. Just a demo on Palau May Get Satellite Power In the Next Decade · · Score: 5, Interesting

    The description here is a bit misleading. From the sound of the article, Palau is really just a testbed for this technology. I'm assuming that they aren't footing any of the bill that is about 6X their GDP.

  4. Re:300 What? on High Efficiency Hybrid Car Planned For 2009 · · Score: 1

    I'm guessing that with an all-electric car you could calculate some equivalent amount of oil/gas that would be theoretically burned at the power plant in order re-charge through the power grid..

  5. preceding release of the new movie? on Startrek.com Shutting Down · · Score: 2, Interesting

    Timing seems a bit strange considering the movie is upcoming; you'd think they'd want to preserve the online fan community to hype the new picture. Especially considering that CBS and Paramount Pictures are one and the same (I think?)

  6. Did I Miss Something? on Fairly Realistic Flying Car Offered for 2009 Delivery · · Score: 1

    Cool as a flying car sounds, how is owning one of these advantageous to driving to your local airport and flying a "normal" plane to your destination? I guess it saves you the issue of finding transportation when you arrive.. Keep in mind that take-off checklists, wait times, etc., will add even more time to the flying car "commute".

  7. Re:Cost? on Perfect Crystals Grown by Cancelling Out Gravity on Earth · · Score: 1

    TFA says, "What's more, the technique will be faster and much cheaper than growing crystals in space..."

    Of course, the researcher is likely projecting costs down the road when fine-tuning reduces costs.

  8. Re:Did they figure it out, or did he? on Teen Plays Videogame With Brain Signals · · Score: 1

    Sorry, misspoke. The neural control is related to real motor commands in the sense of using the activation of neural tissue that may be sending motor commands, but not directly decoding an actual motor command (whatever that may be).

  9. Re:Invasive technique on Teen Plays Videogame With Brain Signals · · Score: 1

    EEG is just not well-suited at this point for this kind of control. The main issue with long-term invasive electrode implantation in neural tissue (aside from the usual health concerns like brain damage and infection) is that over time electrodes become encapsulated by a brain tissue response and are no longer usable for recordings and BCI. There are other strategies for recordings that are not quite as invasive (meaning directly in neural tissue) such as recording from the surface of the dura (covering of the brain). There has been talk of using Near Infrared Imaging to develop a kind of optical Brain Computer Interface.

  10. Re:Did they figure it out, or did he? on Teen Plays Videogame With Brain Signals · · Score: 1

    The subjects are seizure patients at Barnes hospital who have electrode grids placed over tissue that is suspected to be involved in the seizures. The ECoG team takes advantage of this opportunity to work with human subjects (something that is next to impossible to arrange, normally). The tissue being recorded from isn't necessarily primary motor cortex or some other motor region where a "motor command" could be "decoded" (I work in a different motor control lab at WashU-StL but have also worked with one of the main collaborators on this project).

    To answer your question, its a bit of both. Neural plasticity is key in learning to use your brain to move a mouse cursor or play a video game, since you obviously don't possess neural regions that expect to directly control a video game.

    They begin by examining and processing neural recordings while asking the subject to do and/or think about doing various motor tasks (sticking out tongue, moving arm, etc) and determining which electrodes' processed activities appear to be correlated with these movements. Then they do the same while subjects play a "game" with a joystick. The brain-to-Atari control is one of the final stages of the experiment. So really, the subjects do need to learn how to control various degrees of freedom with thought, but its also related to real motor commands.

  11. Re:Could it be? on Google Violates Miro's Copyright? · · Score: 1

    Miró? Isn't that the same artist whose work is reproduced in millions of dormitory "art" posters being sold for $15 a pop in every university student center?

    Yeah, I think its fair to say the Miró estate is interested only in prostituting their art for $$$

  12. Blame Cana... America! on Prof Denied Funds Over Evolution Evidence · · Score: 1

    "the rising popularity in the United States of 'intelligent design' - a controversial creationist theory of life - is eroding acceptance of evolutionary science in Canada." ---- Blaming the US for the ignorance of Canadian Christians.. I don't know how valid this is.

  13. In Other News on Apple Officially Releases Beta Dual Boot Loader · · Score: 1

    2006 Sales of Microsoft Virtual PC rapidly approach zero.

  14. Re:Link to clip on FCC Levies Record Indecency Fine · · Score: 1

    Boy did I go to the wrong parties in high school.

  15. Ouch on Hot Pepper Kills Prostate Cancer · · Score: 1

    Well, I guess I'd rather suffer severe ulcers and heartburn my whole life than contract prostate cancer.

  16. Re:skewed statistics. on Gates Provides Windows Crash Statistic · · Score: 1

    Ha, we don't see the BSOD anymore cause Microsoft likely removed that "feature". Now Microsoft notifies you of system crash via a blank desktop and hidden mouse pointer! But don't worry. If you wait long enough, they'll come back. Really.

  17. Re:phew. on The RIAA's Hit List Named · · Score: 1

    I don't know if it actually matters if you use a default username or not, since they are also identifying users' IP addresses. Notice that the list is much shorter than the number of subpoenas issued. I'm sure they have targets some default users by identifying their IPs.
