    NASA Robotic Rocket Plane To Survey Martian Surface

    By Stuart Fox Posted on 11.24.2009 17 Comments

    Since budget cuts and the inability to overcome problems like boredom and high radiation doses have ruled out any manned mission to Mars in the foreseeable future, NASA has shifted gears back towards a program of robotic exploration. To that end, NASA now wants a rocket-powered UAV to fly around the Red Planet, photographing the surface.

    Hmm, seems as if NASA is just investigating at this stage. They probably investigate a lot of stuff at any one time. I think that it could be a reasonable program, given the problems to be solved for a manned mission. As for the baloon concept, it may have already been proven to be a non starter. The rarefied atmosphere would seem awfully hostile to a 'lighter than air' approach. When I see NASA stories, I can't help but contrast them to the LHC stories. I have no beef with the LHC program -- quite the opposite. However, if it had been under NASA with the same results, there would have been cries for public beheadings by now.

    High-Pressure Diamond Anvil Creates a New Solid from Xenon and Hydrogen

    By Jeremy Hsu Posted on 11.23.2009 9 Comments

    Science under pressure can produce marvelous results, such as an entirely new way to store hydrogen fuel. Researchers combined the noble gas xenon with molecular hydrogen (H2) to make a never-before-seen solid that opens the doors to an entire new family of materials for hydrogen storage.

    Here's hoping. There have been a number of promising schemes in the Hydrogen storage area -- apparently none to date have been adequate.

    Man Diagnosed 'Comatose' For 23 Years Was Actually Conscious All Along

    By Clay Dillow Posted on 11.24.2009 9 Comments

    In what can only be described as a harrowing instance of misdiagnosis, a Belgian man presumed comatose for 23 years after a near-fatal car crash was actually conscious and paralyzed the entire time. Rom Houben, whose real state was discovered three years ago but only now made public, could be one of many falsely diagnosed coma cases, raising serious questions about those diagnosed as "vegetative" and, even more frighteningly, the process by which vegetative people are removed from life support.

    It would appear that the 'misdiagnosis' was caused by not having any method of communication until recent technology advances. Not a case of doctors missing anything. It's a sad story, and maybe there are quite a few others in the same condition. Maybe now these people can be helped. This is a cause for celebration, not blame.

    President Obama Hopes to Jumpstart Science and Technology Education With New Initiative

    By Posted on 11.23.2009 15 Comments

    Elmo and Big Bird may represent old school learning compared to video games, but both Sesame Street and video game programmers have joined forces as part of a new White House initiative aimed at promoting science, engineering and math both in and out of the classroom.

    I dislike President Obama, but I support this effort -- although the money is peanuts. It could at least give some prestige to 'geeks'. Another positve step might be to stop federal requirements for diversity and other PC subjects to be taught in schools -- could allow the teachers time to teach a little science. There are a lot of other contributing factors, it's a complex problem. Strangely, it doesn't really seem to relate to salary. Engineering salaries can be pretty decent, but the educational requirements are stiff. Doesn't seem to be a popular major.

    Rat Brain Modelers Denounce IBM's Cat Brain Simulation as "Shameful and Unethical" Hoax

    By Jeremy Hsu Posted on 11.24.2009 16 Comments

    IBM's claim of simulating a cat cortex generated quite a buzz last week, but now the head researcher from the Blue Brain project, a team that is working to simulate its own animal brain (a rat's), has gone incandescent with fury over the what

    So, a competing scientest disagrees -- so what. The acacdemic community is filled with disputes, although most of them are confined to to letters and articles in some obscure journal ("Professor Xnthi's point 1.i.2 is completely contraindicated by earlier research" ) Maybe IBM is right and the complaints are sour grapes, or maybe they're just making statements that are technically accurate, but imply much more -- I don't know. Let's see if they respond. In any case, I don't blame PS in this case, they're simply reporting claims by a relatively reputable organization. BTW, most of the commentors could use a bit of spelling review.

    Introducing the Popular Science Tech Buyer's Guide

    By Posted on 11.23.2009 2 Comments

    The advantage to working at a place like PopSci is that, between our editors and contributors, I’m surrounded by tech experts I can turn to whenever I’m in the market for a gadget and ask simply, “So which one should I buy?” This year, we decided to package all of that expertise into the Tech Buyer's Guide which we're giving away for free starting today.

    I hate to be negative on a free guide, but : - Vid/Graphic loaded -- makes it slow, hard to navigate and touchy ( I have DSL and a 2.5 Ghz processor) - Descriptions were short and relatively vague -- If they expanded to detail, I couldn't find it. - relatively few devices in each category, and I'm not sure that I agree with the picks

    CERN Successfully Brings Large Hadron Collider Back Online

    Much beset by magnet quenches, birds, bread, black holes, evil time travelers, and fools, the Large Hadron Collider successfully came online and orbited a proton beam today! Photographs of the triumphant moment are within.

    Good, they've had their troubles. I've been amazed at the lack of media coverage on this -- in the US and Europe. If this was a NASA project, seven kinds of hell would have been dropped on them by now.

    This simple-looking white powder can get mercury-contaminated water 100 times as clean as any other method, for about half the cost. Each grain is actually a carefully engineered molecular sponge designed to absorb more than half its weight in mercury.

    Mourning the Death of the Meta Media Experience

    By Tom Conlon Posted on 11.20.2009 9 Comments

    I tend to think of my cable bill kind of like my health insurance premium. Every month, I begrudgingly pony up the funds necessary to continue this so-called “service” wondering the what the heck it is I’m actually paying for--especially since most of what I regularly watch can be found online in some form--all the while deathly afraid of the consequences should I ever stop wiring in my money. Every month, I consider amputating cable from my bottom line once and for all. But what’s holding me back is that I think I might actually miss it.

    I think that the download system goes awry in a few ways 1. Channel flipping -- I (and others) often flip between shows on occasion. In my case, this is especially true for football ( not all of which is available on free local channels). Can't imagine how you'd replace that with downloads. 2. Checking for new shows. I read the tv skeds, but there are often cases where I see the plugs for a new show and give it a chance. 3. Checking for shows in general. Hulu doesn't actually have that large of a selection, but it takes me a long time to search through it. Maybe Apple will do a better job. 4. Bandwidth. Right now cable /satellite send an amazing amount of data out in a fairly efficient manner. Downloading will likely increase the required bandwidth significantly. 5. Equipment. Now I will need a computer more or less dedicated to downloads. I will also need something to connect it to various TVs -- unless I choose to watch it on my computer. Of course, I could always watch it on my 4 inch smartphone ( whoopee) 6. Industry. This won't fly unless the entertainment industry does a major shift to support it. I doubt that they will. I think that this will always be a niche market. Yes, it can be fun, and there will be those who've cut the cable. But there are those who don't have TVs -- or even radios.

    Roboticists Want to Make You an Electric Car Customized for Your Personal Commute

    Drivers who want to know energy tradeoffs between gas guzzlers and electric cars may find some help at the ChargeCar project, where researchers have begun investigating how to customize electric vehicles to meet individual commuting needs. A smart power management system could even boost electric vehicle efficiency and extend battery life.
